PCOS makes it more difficult for the body to use the hormone insulin, which normally helps convert sugars and starches from foods into energy. This condition, called insulin resistance, can cause insulin and glucose to build up in the bloodstream.
High insulin levels increase the production of male hormones called androgens. High androgen levels lead to symptoms such as body hair growth, acne, irregular periods and weight gain.
The weight gain triggered by male hormones is typically in the abdomen. So, women with PCOS are more likely to have an apple shape rather than a pear shape.
