Polycystic Ovary Syndrome (PCOS)
Polycystic ovary syndrome is a common hormonal disorder that affects how a woman's ovaries work, often causing irregular periods and excess androgen levels. It is a leading cause of infertility but can be managed with lifestyle changes and medication.
Overview
Polycystic ovary syndrome is a common hormonal disorder that affects how a woman's ovaries work, often causing irregular periods and excess androgen levels. It is a leading cause of infertility but can be managed with lifestyle changes and medication.
Understand this condition
In PCOS, the ovaries produce higher levels of androgens, which are typically considered male hormones. These high levels prevent the ovaries from releasing an egg every month, leading to irregular periods and fertility issues. Additionally, the body may struggle to use insulin effectively, causing blood sugar levels to rise.
Why it happens
PCOS occurs when a chain reaction of hormonal imbalances prevents normal egg development and ovulation. High insulin levels trigger the ovaries to produce excess testosterone, which disrupts the menstrual cycle and causes physical symptoms. Over time, these imbalances can lead to metabolic issues and structural changes in the ovaries.
