Actually, PCOS is something to be concerned about even if you aren't deciding to have children. With PCOS, your whole endocrine system can be thrown out of balance, leading to a variety of problems. Women with PCOS are at a higher risk for developing diabetes and a lot of women are on medications like Metformin which is a medication used to treat diabetes. Left untreated, things could get worse. You may end up easily gaining weight and have trouble losing it no matter how much you exercise and diet and that extra weight is hard on your body. Women with PCOS typically have an elevated testosterone level, which leads to symptoms such as adult acne, excessive body and facial hair, and losing hair on your head. If you end up with insulin resistance, you might end up with skin spots and/or skin tags. All of which can be harsh on a persons self esteem. Not to mention the effects a hormonal imbalance can have on a persons mental health. Look up the symptoms of imbalances in estrogen and progesterone. If those are out of balance, you could end up dealing with depression, mind fog, irritability, etc. In essence, this is a condition that should be treated and not taken lightly.
