Which is the most common hormone disorder found in women?
Polycystic ovary syndrome (PCOS) is extremely prevalent and probably constitutes the most frequently encountered endocrine (hormone) disorder in women of reproductive age. Having the disorder may significantly impact the quality of life of women during the reproductive years, and it contributes to morbidity and mortality by the time of menopause.
What are the disorders associated with PCOS?
PCOS women are at increased risk for coronary heart disease and type 2 diabetes mellitus. Their risk factors include central obesity, hypertriglyceridemia, low levels of high-density lipoprotein (HDL) cholesterol, hypertension, and elevated fasting plasma glucose concentrations. PCOS women should undergo screening for hypertension, abnormal lipid profiles, insulin resistance, and reproductive disorders including cancer of endometrium.
What is PAO?
A subgroup of women (up to 30%) may have subtle abnormalities resembling PCOS called PAO. While PCOS occurs in at least 5% of the population, the isolated finding of polycystic-appearing ovaries (PAO), which meets the classic ultra-sonographic criteria, occurs in 16–25% of the normal population without evidence of the full-blown syndrome. These characteristics include androgenic ovarian responses to stimulation with gonadotropins, as well as metabolic changes such as lowered high density lipoprotein-C levels and evidence of insulin resistance. While these data generated by our group need further assessment, these findings suggest that important yet silent abnormalities may exist in otherwise normal women who have a trait of PCOS (namely PAO).
What is the most important reproductive concern in women with PCOS?
The most frustrating reproductive concern for women with PCOS is pregnancy loss. The spontaneous abortion rate in PCOS is approximately one third of all pregnancies. This is at least double the rate for recognized early abortions in normal women (12–15%). Reasons for this are unclear although hypotheses include elevated LH levels, deficient progesterone secretion, abnormal embryos from atretic oocytes, and an abnormal endometrium.
How PCOS negatively impact psychosocial development of young women?
Women with PCOS, particularly those with hirsutism, have an increased prevalence of reactive depression and minor psychological abnormalities. There is also evidence of increased psychological stress and an increased catecholamine response to provoked stress. The overall quality of life is decreased in hirsute women. The presence of hirsutism and menstrual irregularities, especially in younger patients, is extremely distressing and has a significant negative impact on their psychosocial development.
Which cancer has increased risk in women with PCOS?
Women with PCOS are at increased risk of endometrial cancer. Chronic unopposed estrogen exposure is probably the proximate risk factor. This may be confounded by obesity, hypertension, and diabetes, which are known correlates of endometrial cancer risk. It is imperative to screen all women with PCOS, even those who are considered too young to develop endometrial hyperplasia and carcinoma.
Can low grade inflammation be a risk factor of PCOS?
Women with PCOS have significantly increased CRP concentrations relative to those in healthy women with normal menstrual rhythm and normal androgens. Inflammatory marker like CRP concentrations is more with PCOS. It correlates with the degree of obesity and inversely with insulin sensitivity, although not with total testosterone concentrations.
Which is a better predictor of metabolic syndrome in PCOS?
Obesity, a key determinant of insulin concentrations, appeared to have an independent effect on risk for the metabolic syndrome. In Anovulatory PCOS women a waist circumference of >83.5 cm along with biochemical evidence of hyperandrogenism is a powerful predictor of the presence of metabolic syndrome and insulin resistance. Age and central obesity (waist-hip ratio/waist circumference) are better predictors of metabolic syndrome in women with PCOS compared to other parameters including BMI.
How Metformin helps in PCOS?
Metformin is the most thoroughly investigated insulin-lowering agent used to treat PCOS; it enhances insulin sensitivity in the liver, where it inhibits hepatic glucose production, and in muscle, where it improves glucose uptake and use.
The persistence of regular ovulatory menstrual cycles in the 6 months after the end of treatment demonstrates that metformin treatment provides lasting benefits. All girls maintain a BMI <25 kg/m2, and this can play a role in normal ovulation menstrual cycles.
What is the role of AMH in diagnosis of PCOS?
Serum anti-Mullerian hormone (AMH), produced in the ovaries by small follicles, is usually elevated in women with PCOS and correlates with the severity of this syndrome. AMH plays an important role in inhibiting follicular development by decreasing the sensitivity of the follicles to FSH and by inhibiting granulosa cell aromatase. Serum AMH appears as a sensitive and specific parameter that predict PCOS than antral follicle count and ovarian volume.
What is the source of DHEA in PCOS?
Serum DHEAS has been found to be elevated in some women with polycystic ovary syndrome (PCOS). In PCOS, it has been found that there are actually two different sources of androgens, the ovary and the adrenal. In women with PCOS, the theca cells are overactive and proliferate excessively, producing too much testosterone. Unfortunately, in 40-50% of women with PCOS, there is also another source of androgens, which is the adrenal glands. The adrenal glands produce all of the DHEA in the body.
