Do mood swings and alcohol affect polycystic ovaries?

Not really: Pcos is also called stein leventhal syndrome. Strangely, you don't have to have ovarian cysts to have this disease. Symptoms include lots of things including acne, excessive hair growth, obesity and infertility. Treatment is variable depending on the symptoms and severity. Lots of docs can help you. Mood swings and alcohol can make any disease feel worse, or better! but don't treat yourself.
