Polycystic Ovary Syndrome (PCOS) is a common hormonal disorder that affects people with ovaries, typically during their reproductive years (usually between 15 and 44). It can impact various aspects of health and is often associated with a range of symptoms. Here's an overview:
Irregular Periods : This is one of the most common symptoms. Menstrual cycles might be infrequent, prolonged, or absent altogether.
Excess Androgens : People with PCOS may have higher levels of male hormones (androgens), which can lead to symptoms like acne, excess facial or body hair (hirsutism), and thinning hair on the scalp.
Polycystic Ovaries : The ovaries may become enlarged and contain numerous small cysts (fluid-filled sacs). These cysts are typically harmless but can interfere with the normal functioning of the ovaries.
Weight Gain : Many individuals with PCOS struggle with weight gain, especially around the abdomen, and may find it more difficult to lose weight.
Infertility : PCOS is one of the leading causes of infertility in women, primarily because it can affect ovulation (the release of eggs from the ovaries).
Other Symptoms : These can include mood swings, fatigue, sleep problems, and thinning hair.
The exact cause of PCOS is unknown, but several factors may contribute:
Hormonal Imbalance : High levels of insulin or elevated androgens can disrupt the normal reproductive cycle.
Genetic Factors : There may be a family history of PCOS or other hormonal disorders.
Insulin Resistance : Many people with PCOS have insulin resistance, where the body can't use insulin effectively. This can lead to higher insulin levels, contributing to other symptoms like weight gain and infertility.
PCOS is typically diagnosed based on symptoms, a physical exam, and tests such as:
Blood tests to check hormone levels (androgens, insulin, etc.).
Ultrasound to look at the ovaries and check for cysts.
