Abstract
BACKGROUND One of the most important risk factors for osteoporotic fractures in postmenopausal women is elevated bone turnover (EBT), occurring in 25-30% of this population. This study's aim was to find a correlation between bone resorption and bone formation markers to assess bone turnover rate and qualify an individual postmenopausal woman as a possible EBT subject. MATERIAL/METHODS Three hundred twenty postmenopausal women (> or = one year after the last menstruation, < or = 70 years old) were enrolled at seven clinical sites in this cross-sectional observational study conducted within the EPOLOS. The group was a random sample of the population. The study was performed in a referral center involved in the diagnosis and treatment of osteoporosis. The exclusion criteria included pregnancy, cancer, fracture in the last year, and overweight (> 100 kg). Bone mineral density (BMD) measurements of the lumbar spine, total hip, trochanter, and femoral neck regions were performed. Bone resorption and formation rates were evaluated by serum levels of C-terminal telopeptide of type I collagen (CTX) and osteocalcin (OC), respectively. RESULTS Using logistic regression to correlate the concentrations of CTX and OC it was possible not only to distinguish the EBT subgroup, but also to construct a simple nomogram for easy classification of individual patients as possible EBT subjects. EBT patients showed generally decreased BMD values and increased bone formation and resorption rates. CONCLUSIONS Evaluation of both CTX and OC levels enables a more proper indication for EBT. The proposed nomogram may assist in evaluating outcome from the two markers of bone turnover.

Abstract
INTRODUCTION The activity of androgen receptor (AR) is modulated by a polymorphic CAG trinucleotide repeat in receptor gene. There are suggestion, that there are association between polymorphism androgen receptor gene and the occurrence typical features of metabolic syndrome in men. The metabolic syndrome is more frequent with aging. We knows, that polymorphism androgen receptor gene is associated with risk of prostate cancer and with occurrence Kennnedy's syndrome. However the association of this polymorphism for occurrence of hypertension, obesity and lipid and glucose concentration disturbance is not examined. MATERIAL AND METHODS The original study population consisted 268 randomly selected wroclaw population men aged 45-65. The physician examination include mensuration of blood pressure and antropometrical analysis. The men were coming on an empty stomach between 8.00 and 10.00 am for blood taken. The blood were taken for biochemical measurements and for genetic analysis CAG repeat in androgen receptor gene. RESULTS There is statistical significant differences between number of CAG repeat in men with normal and higher concentration of cholesterol LDL. There were no significant differences between number of CAG repeat in men in dependent of value of blood pressure and concentration of insulin, glucose, cholesterol HDL, total cholesterol and triglicerides. CONCLUSIONS The investigation results are not unambiguous with regard to influence of polymorphism androgen receptor gene for occurrence of metabolic syndrome in men. We found only association between number of CAG repeat an androgen receptor gene and concentration of cholesterol LDL (which it is as we knows atherogenic factor).

Abstract
The present paper describes a case of a breast cancer patient in whom lymphoscintigraphy identified metastases in the internal mammary nodes whilst the axillary lymphatic center was tumor-negative. Because of the lymph node involvement, cancer was restaged from original I to IIIc. Consequently, the patient was qualified for chemotherapy with docetaxel and doxorubicin. The case described is another contribution for the routine application of sentinel lymph node biopsy (SLNB) in breast cancer patients.

Abstract
AIM Vitamin D could have a direct effect on adipocyte differentiation and metabolism and might be involved in glucose regulation of insulin secretion. In recent years several polymorphisms in the gene encoding the vitamin D receptor (VDR), which are potent to alter the activity of VDR protein, have been described. The present study aimed to investigate the prevalence of the VDR BsmI polymorphism and its association with anthropometric and biochemical features of metabolic syndrome in postmenopausal women. MATERIALS AND METHODS We studied 351 randomly selected healthy postmenopausal women, with mean age of 55.43 +/- 2.75 years and mean body mass index (BMI) of 27.5 +/- 4.78 kg/m2, to evaluate the frequency of BsmI polymorphism (by restriction fragment length polymorphism-polymerase chain reaction) in the VDR gene and to find out whether there is an association between this polymorphism and BMI, total fat volume and visceral fat (as determined by total body dual-energy X-ray absorptiometry), blood pressure, lipid profile (total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol, triglycerides) glucose and fasting insulin in the whole group, as well as subgroups of obese and non-obese women. RESULTS The prevalence of BsmI genotypes in the study group was 51.0% Bb, 37.3% bb and 11.7% BB. Genotype distribution did not differ from that expected under Hardy-Weinberg equilibrium conditions (chi2 = 2.95, p = 0.22). Apart from LDL-C levels (F = 3.46, p = 0.032), there were no significant differences in anthropometric or metabolic parameters between genotypes. CONCLUSIONS The BsmI polymorphism in the VDR gene does not seem to predispose to obesity and insulin resistance, but the BB genotype is connected with an unfavorable lipid profile.

Abstract
INTRODUCTION It was found that vitamin D may have a direct effect on adipocyte differentiation and metabolism and might be involved in the glucose regulation of insulin secretion, as suggested from the discovery of a nuclear localization of 1,25-(OH)(2)D(3) in pancreatic islets. In recent years, several polymorphisms in the VDR gene which are able to alter the activity of VDR protein have been described. The BsmI and FokI polymorphisms were described in relation to obesity and type 2 diabetes. The aim of the study was to find whether there are associations between BsmI and FokI polymorphisms and anthropometric (BMI, WHR, BP) and biochemical parameters describing metabolic syndrome. MATERIALS AND METHODS Studied were 176 randomly selected men aged 25-65 years (mean: 51.99 years) with a mean BMI of 28.06 kg/m(2). Two polymorphisms of the VDR gene (FokI and BsmI) were explored using the PCR-RFLP method. Serum glucose, insulin, total cholesterol, LDL, HDL, and TG were measured using commercially available kits. RESULTS It was found that BB carriers tend to have higher BMI (29.00 +/- 3.74 versus 26.81 +/- 3.76, p = 0.024) and waist circumference (101.79 +/- 10.59 versus 96.23 +/- 10.35, p = 0.014) compared with the bb genotypes. Similarly, FF and Ff carriers had higher fasting insulin levels than the ff genotypes (12.30 +/- 10.26 versus 9.76 +/- 5.88, p = 0.001 and 9.76 +/- 5.88 vs. 6.35 +/- 2.64, p = 0.008), and lover cHDL levels in comparison to ff genotypes (52.28 +/- 10.02 versus 60.63 +/- 16.58, p = 0.015 and 53.70 +/- 12.03 versus 60.63 +/- 16.58, p = 0.032. Besides these, no significant differences were found. CONCLUSIONS The BsmI VDR polymorphism seems to influence BMI, while the FokI VDR polymorphism appears to affect insulin sensitivity and serum cHDL level.

Abstract
OBJECTIVES Most research confirms that metformin therapy has a positive influence on cardiovascular risk factors (CVRF) such as dyslipidemia, insulin resistance and hyperandrogenism in polycystic ovary syndrome (PCOS). The aims of the present study were to establish other CVRF, such as plasma adiponectin, tumor necrosis factor-alpha (TNFalpha), interleukin-6 (IL-6) and C-reactive protein (CRP) levels, in obese premenopausal women with PCOS and to investigate the effect of metformin treatment on these factors. MATERIALS AND METHODS The study group consisted of 29 PCOS woman with body mass index (BMI) >25 kg/m(2). They were treated over 6 months with 500 mg metformin twice daily. Twenty-nine healthy individuals matched for age and BMI were controls. Adiponectin, TNFalpha, IL-6 and CRP levels were examined in all PCOS (before and after treatment) and control women. RESULTS In the PCOS group significantly lower plasma adiponectin and TNFalpha levels were observed, whereas there were no differences in plasma IL-6 and CRP levels between PCOS and control groups. Plasma adiponectin increased significantly after metformin treatment, but levels of inflammatory factors did not change.

Abstract
INTRODUCTION The aim of this study was to examine the association of Pro12Ala PPARgamma2 polymorphism with anthropometric and biochemical parameters defining the risk for the development of metabolic syndrome in a healthy population of men. MATERIAL AND METHODS The study group consisted of 176 healthy men, aged 25-65 years (average 54.16 years). Polymorphisms of the PPAR-g gene (Pro12Ala, Ala12Ala, Pro12Pro) were explored using the PCR-RFLP method. Plasma glucose, insulin, total cholesterol, LDL, HDL and TG were measured using commercially available kits. RESULTS The genotypic distribution of the Pro12Ala polymorphism was as follows: Pro/Ala 69.8% (n = 123), Ala/Ala 28.4% (n = 50) and Pro/Pro 1.8% (n = 3). The Pro12Ala and Ala12Ala subjects did not differ in any of the measured variables. The non-obese (BMI < 30 kg/m(2), n = 117) and obese subpopulations (BMI > 30 kg/m(2), n = 56) did not significantly differ in the distribution of the genotypes. In the nonobese subpopulation, the homozygous Ala12 carriers (n = 38, 32.4%) had higher systolic blood pressure, plasma triglycerides, insulin levels and HOMA-IR. CONCLUSIONS We conclude that despite the high frequency of the Ala allele at the PPAR-gamma2 gene in our population of Polish men, the Ala12 allele does not appear to improve insulin sensitivity or have an influence on the occurrence of obesity. It remains to be explained by larger studies if this polymorphism carries any risk of the development of metabolic abnormalities in non-obese men.

Abstract
OBJECTIVES Some studies indicate that the Trp64Arg polymorphism in the gene encoding the beta(3)-adrenergic receptor (ADRB3) is associated with obesity, insulin resistance and earlier onset of type 2 diabetes mellitus. The aim of the present study was to evaluate the frequency of ADRB3 polymorphism and its association with metabolic syndrome in postmenopausal women. METHODS We performed the study on 284 randomly chosen postmenopausal women, aged 50-60 years, who were then selected to the study. Measurements of anthropometric parameters and biochemical estimations such as lipid profile, glucose and insulin level in serum were carried out using commercial kits. ADRB3 genotyping was performed by polymerase chain reaction and mini-sequencing. RESULTS The frequency of the Trp64/Arg64 genotype in the investigated population was 13%, and of the Trp64/Trp64 genotype, 85%. The Arg64/Arg64 genotype was present in only 2% of women. Metabolic syndrome was recognized in 22% of women bearing Trp64/Arg64 genotype and in 14% of women bearing Trp64/Trp64 genotype, without a statistically significant difference between the two groups (p > 0.05 in the chi(2) test). Women bearing the Trp64/Arg64 genotype had lower serum levels of high-density lipoprotein cholesterol (HDL-C) than Trp64/Trp64 genotype women (63.2 +/- 13.0 vs. 71.4 +/- 17.4 mg/dl). Both groups did not differ in any other investigated parameter. CONCLUSION Trp64Arg polymorphism of the beta(3)-adrenergic receptor gene is not related to metabolic syndrome in postmenopausal Polish women; however, it seems to be associated with decreased HDL-C levels.

Abstract
Consensus statement of the Polish Society for Endocrinology, regarding presurgical somatostatin analogs in acromegaly has been presented. It is suggested to administer depot somatostatin analog (Octreotide LAR at the dose 20 mg and then 30 mg or equivalent doses of Lanreotide Autogel 90/120 mg every 4 weeks) in order to normalize or suppress to a maximal extent GH and IGF-1 concentrations. The period of therapy in case of microadenoma would be at least 3 months (targets: biochemical improvement, reduced risk of disease's complications, perioperative risk reduction, inhibition of tumor growth). The period of therapy in case of macroadenoma would be at least 6 months, until maximal possible reduction of GH and IGF-1 concentrations (targets: tumor shrinkage, biochemical improvement, reduced risk of disease's complications, perioperative risk reduction). Using an uniform approach in a group, as numerous as possible, of treated patients would allow objective evaluation of long-term efficacy of the treatment.

Abstract
BACKGROUND Dehydroepiandrosterone (DHEA) is postulated to have antiatherogenic properties, but the possible mechanism of this action is unclear. The aim of this study was to determine the influence of endogenous DHEA-S on the levels of some factors playing significant roles in atherogenesis. MATERIAL/METHODS In a group of 40 premenopausal women, relationships between endogenous DHEA-S and serum lipids and the apolipoproteins A1 (apoA1) and B (apoB), serum lipid peroxide (LPO), and total antioxidant system (TAS) concentrations as markers of the serum antioxidant-prooxidant balance were measured as well as clinical and biochemical parameters playing roles in atheromatosis such as the type of obesity and the serum glucose, insulin, insulin-like growth factor (IGF-1) and homocysteine (HCY) concentrations. RESULTS Statistical analysis revealed significant correlation (p<0.05) between serum DHEA-S level and the serum concentrations of: HDL(2)-C (r=0.53), HDL(2)-C/HDL(3)-C (r=0.58), TG (r=0.35), IGF-1 (r=0.39), and HCY (r=-0.44). There was no statistically significant correlation between DHEA-S level and other biochemical and clinical parameters (age, BMI, WHR) found in this study. CONCLUSIONS Despite unfavorable correlation between DHEA-S and TG concentration, the results of this study indicate a potential antiatherogenic action of DHEA which may occur through various mechanisms: by increasing HDL(2)-C and the HDL(2)-C/HDL(3)-C ratio, which has an atheroprotective effect, by elevating the serum IGF-1 concentration, or by decreasing the HCY level. These preliminary results, however, require further investigation.

The aim of the present study was to evaluate the frequency of this polymorphism and its relationship with obesity and oxidative stress in postmenopausal women. MATERIAL AND METHODS We performed the study on 200 women, aged 50-60 years. Estimation of anthropometric parameters and total body fat, android and gynoid fat deposits was carried out using dual-energy X-ray absorptiometry. Oxidative stress was estimated by measurement of thiobarbituric acid-reactive substances (TBARS) in serum. Blood for analysis was collected before, directly after and 6 h after a 30-min physical test on a cycle ergometer. ADRB3 genotyping was performed by polymerase chain reaction. RESULTS The frequency of Trp64/Arg64 genotype in the investigated population was 12%, and of Trp64/Trp64 was 87%. The Arg64/Arg64 genotype was present in only 1% of women. Women bearing the Trp64/Arg64 genotype did not differ in any measured anthropometric parameters from women bearing the Trp64/Trp64 genotype. Moreover, genotype had no influence on oxidative stress parameters. Likewise, in both groups, mean plasma level of TBARS was increased significantly (p < 0.05) directly after the endurance test and remained elevated 6 h after the test. CONCLUSIONS The Trp64Arg polymorphism of ADRB3 seems to not be related to obesity in postmenopausal women. Moreover, the Trp64Arg polymorphism has no influence on oxidative stress intensification after standardized physical effort in postmenopausal women.

Abstract
INTRODUCTION Some studies indicate, that the Trp(64)/Arg(64) polymorphism of beta(3)-adrenergic receptor (ADRB3) is associated with obesity, insulin resistance and earlier onset of type 2 diabetes mellitus. The aim of our study was evaluation of frequency of this ADRB3 polymorphism and his association with metabolic syndrome parameters and oxidative stress in postmenopausal women. MATERIAL AND METHODS We performed the study among 94 women, aged 50-60, selected randomly from Wroclaw city population. Estimation of anthropometric parameters, densitometry (total body fat, android and gynoid deposits--using DPX(+) Lunar, USA device) and biochemical estimations such as lipid profile, glucose, insulin, estradiol and FSH serum level (using commercial kits) were carried out. Oxidative stress was estimated by measurement of thiobarbituric-reactive substances (TBARS) serum concentration, using Yagi method, on spectrofluorimeter Perkin-Elmer LS55. Blood for analysis was collected before, direct after and 6 h after the 30-minutes physical test using cycloergometer. ADRB3 genotyping was performed by PCR and mini-sequencing using ABI 310 sequencer (Applied Biosystems). RESULTS The frequency of Trp(64)/Arg(64) genotype in investigated population was 15.8%. The Arg(64)/Arg(64) genotype had only one woman. Women bearing Trp(64)/Arg(64) genotype showed higher mean serum level of triglycerides and lower serum level of HDL-cholesterol in comparison to women bearing Trp(64)/Trp(64) genotype, however without statistical significance (p > 0.05) (respectively, means +/- SD for triglycerides: 140.3 +/- 64.1 vs. 113.9 +/- 56.2 mg/dl; and for HDL-cholesterol: 60.9 +/- 11.9 vs. 67.0 +/- 16.9 mg/dl). Both groups did not differ in any other investigated anthropometric nor biochemical parameter. CONCLUSIONS 1. The Trp(64)/Arg(64) polymorphism of beta(3)-adrenergic receptor could be associated with lipid profile disorders observed in metabolic syndrome in postmenopausal women, however it should be explained basing on the study with more included subjects. 2. The Trp(64)/Arg(64 )polymorphism of beta(3)-adrenergic receptor has no influence on oxidative stress intensification after standardized physical effort in postmenopausal women.

Abstract
Obesity is epidemic of 21st century, its visceral form is associated with increased risk for type 2 diabetes, cardiovascular disease, hypertension and increased mortality due to consequences of the disease. This type of obesity is a common diagnostic and therapeutic problem in gynecological practice. This especially concerns polycystic ovary disease, in which this type of obesity with its metabolic consequences is one of the important factors in etiology and additionally may lead to remote metabolic and cardiovascular problems. Another group of women in which this type of obesity plays an important role are climacteric women in whom redistribution of adipose tissue with increase in visceral fat deposit occurs. On the basis of current viewpoints and own experiences, the authors propose a diagnostic-therapeutic algorithm in women with visceral obesity and polycystic ovary disease or climacteric period. In case with cardiovascular risk factors (waist circumference over than 80cm, serum triglycerides over 1.7mmol/l, HDL cholesterol lower than 1.0mmol/l, blood pressure over 130/85mmHg and fast serum glucose levels over 100mg/dl) the therapeutic model focuses on the recognize risk factors. It must be considered that diet and physical activity play a very important role in the therapy.

Abstract
AIM OF THE STUDY to determine the effect of rosiglitazone on plasma adiponectin and resistin levels in obese, non-diabetic polycystic ovary (PCO) subjects and relationship between circulating adipocytokines, insulin resistance and lipid profile. MATERIAL AND METHODS PCOS women were treated 6 months with 4mg rosiglitazone daily (the blood was tested before and 3; 6 months after treatment). Plasma resistin, adiponectin, total-cholesterol, triglycerides, HDL- and LDL-cholesterol levels were examined in 12 obese PCO women (age 18-45) with BMI >30. Twelve healthy, obese individuals with BMI >30 were controls. We measured peripheral insulin resistance using FIRI and Quicki indexes derived from fasting insulin and glucose levels, and insulin area under the curve during an oral glucose challenge. RESULTS BMI, WHR, % of total fat, FIRI, Quicki and fasting insulin were comparable in both groups. We observed significantly lower adiponectin and resistin plasma levels in PCO woman. Fasting plasma insulin level was similar in both groups and didn't change after treatment. We noticed decrease in insulin area under the curve after 3 and 6 months of rosiglitazon (respectively p = 0.029 and 0.03). There were decreases after treatment in BMI and WHR and beneficial changes in lipid profile--but not significant. Plasma adiponectin level increased after 6 months of treatment (p = 0.03) but plasma resistin level didn't change. We revealed negative correlation between adiponectin, BMI and fasting glucose. CONCLUSION Our data confirm that in obese, hyperinsulinemic PCO women adiponectin and resistin levels were decreased. After therapy we observed increase in adiponectin level and no change in resistin level.

Abstract
OBJECTIVE Data concerning the relationship between sex steroid hormones and the cellular antioxidative enzyme system are controversial. We investigated the effects of oestradiol deficiency after menopause and the influence of transdermal oestradiol therapy (ET) and hormonal (oestradiol plus medroxyprogesterone) replacement therapy (HT) on erythrocyte superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT). GSH and selenium (Se) concentrations were also estimated. Serum lipid peroxide (LPO) levels were measured as an indicator of free-radical production and lipid peroxidation. PATIENTS The study group consisted of 80 postmenopausal women, divided into two subgroups: 26 women with surgically induced menopause (ET1) and 54 women with physiological menopause (HT1). Forty premenopausal healthy volunteers were controls (C group). RESULTS LPO was higher in postmenopausal women and decreased after both ET and HT. GSH-Px and GSH were lower in the postmenopausal groups but increased significantly after both types of therapy. Se concentrations did not differ significantly among the groups. CAT activities were similar in all groups and decreased after ET and HT. SOD activities in postmenopausal women were similar to those in the C group and did not change significantly after treatment. CONCLUSIONS The administration of natural oestrogens to postmenopausal women diminishes oxidative stress and increases antioxidative cell potency.

Abstract
AIM The aim of the present study was to investigate the influence of endogenous estradiol and estrogen and estrogen-progestin therapies on concentration in pre- and postmenopausal women. MATERIALS AND METHODS The study groups consisted of 26 women with surgical menopause (mean+/-standard deviation (SD): age 51.8+/-2.6 years, body mass index (BMI) 26.45+/-4.56 kg/m(2)), 54 with natural menopause (mean+/-SD: age 50.5+/-3.0 years, BMI 25.75+/-4.09 kg/m(2)) and 40 premenopausal controls (mean+/-SD: age 48.3+/-2.3 years, BMI 26.23+/-4.12 kg/m(2)). The group with surgical menopause received estradiol transdermally (50 microg/day) and those with natural menopause received additionally medroxyprogesterone acetate (5 mg/day) for the last 12 days of the cycle. Before and after 4 months of therapy, body weight, waist and hip circumferences and blood pressure were measured, and BMI and waist-to-hip ratio (WHR) were calculated. Serum leptin, follicle-stimulating hormone (FSH), estradiol (E(2)), testosterone, prolactin and dehydroepiandrosterone sulfate (DHEAS) were measured prior to and after treatment. RESULTS Leptin concentrations did not differ statistically among the groups. No correlations between leptin and E(2), FSH, prolactin, testosterone and DHEAS concentrations were found in any of the groups before and after treatment. Leptin level correlated positively with body mass, BMI and hip and waist circumferences in all groups. There were no correlations between leptin and WHR in the pre- and postmenopausal groups. In the premenopausal group and in some postmenopausal groups, serum leptin level correlated with blood pressure. CONCLUSIONS Endogenous E(2) and androgens in premenopausal women and estrogen and estrogen-progestin therapies in postmenopausal subjects do not influence serum leptin concentrations. Leptin level is related to body mass and BMI, but not to sex hormone status. The distribution of adipose tissue and the type of obesity (android or gynoid) have no influence on serum leptin concentration. The correlation between serum leptin level and blood pressure requires further investigation.

Risk factors of cardiovascular disease in GH-deficient adults with hypopituitarism: a preliminary report. Med Sci Monit 2006; 12:CR75-80.

Abstract
BACKGROUND We estimated the influence of GH deficiency (GHD) in adults on chosen risk factors of cardiovascular disease and bone density. MATERIAL/METHODS Fifty-four adults (mean age: 50.4 years) with hypopituitarism were studied. We measured blood pressure, body mass index, waist-to-hip ratio, total body fat, and bone mineral density and the serum levels of lipids, glucose, insulin, pituitary hormones, estradiol, testosterone, and thyroxine, and the excretion of free cortisol in 24-h urine. GHD was confirmed with the insulin intravenous test (IIT) with a GH response to IIT of <3 microg/ml. The control group consisted of 73 healthy adults. RESULTS Increased levels of LDL-cholesterol and triglycerides and decreased levels of HDL-cholesterol in the GHD group were observed. Fasting serum glucose and insulin levels were significantly higher in the GHD group than in controls. Significant differences in the QUICKI and FIRI indexes were observed. Twenty-three percent of the hypopituitary patients were hypertensive and 65% were obese. The percentage of total body fat was significantly higher in the studied group than in controls. Thirty-seven percent of the GHD patients were osteoporotic and 23% were osteopenic. CONCLUSIONS An atherogenic lipid profile, insulin resistance, obesity, and increased body and trunk fat in GHD adults may cause the higher risk of cardiovascular disease in these patients. GHD adults should receive human recombinant GH along with conventional replacement therapy. This may be a useful method in protecting against early onset of atherosclerosis, metabolic disturbances, and osteoporosis, especially in young patients.

Abstract
The etiology of obesity is multifactorial and still unclear. Genetic factors play a significant role and include several gene candidates: polymorphisms of genes for ss(2)-adrenoreceptor, resistin, estrogen receptor-a and peroxisome proliferator-activated receptor-gamma. Moreover, peptides regulating hunger and satiety, e.g. leptin, galanin, cholecystokinin and neuropeptide Y, and altered nutritional patterns have been implicated. Also, factors associated with aging, e.g. decreased levels of growth hormone and dehydroepiandrosterone, and the activity of the sympathetic nervous system (resting metabolism and thermogenesis) cannot be disregarded. Participation of the sex steroids and inflammatory factors has also been postulated in the etiology of obesity. Three phenotypes of obesity are postulated; however, the visceral (abdominal) phenotype is typical of postmenopausal women and is characterized by several metabolic disorders with high risks of diabetes mellitus type 2 and cardiovascular disease. On the basis of personal experience and data from evidence-based medicine, diagnostic-therapeutic algorithms of climacteric obesity are presented.

Abstract
Human life was prolonged by 30 years in the past century, with the result that about 40% of a woman's life falls within the postmenopausal period. The consequences, both early and remote, in the form of cardiovascular disease, osteoporosis and neoplastic disease are most pronounced in women suffering from one of the most common diseases, i.e., diabetes mellitus and the metabolic syndrome preceding it. These patients are problematic for physicians, and for this reason a study of diagnostic and therapeutic management was undertaken on the basis of our own experience as well as examination based on evidence-based medicine. Prior to making therapeutic decisions it is necessary to determine cardiovascular, thromboembolic and breast cancer risk factors. Hormonal therapy may be helpful in young postmenopausal women who are free of risk factors, and its composition and route of administration are significant considerations. Women with risk factors and who are more than 10 years after menopause should be administered alternative therapy depending on the diagnosed pathology.
