PCOS stands for polycystic ovary syndrome, a relatively common hormone imbalance that effects nearly 1 out of every 10 women worldwide. It is diagnosed in teens born with female reproductive organs and is often diagnosed during the early to mid-teen years. Many teens will experience symptoms such as irregular periods, unwanted hair growth, difficulty losing weight, and/or acne. Since PCOS is caused by hormone imbalances, it’s possible for teens to feel tired. It’s super important to speak to your health care provider (HCP) about your fatigue. Once you speak with your HCP, they may decide to draw some laboratory tests (a quick blood test) to look at your hormone levels. These levels will help determine if your fatigue (tiredness) is caused by your PCOS or something else.
