Signs and symptoms of polycystic ovary syndrome 

Polycystic ovary syndrome, otherwise known as PCOS, is problem that plagues many women who are in their reproductive years. WebMD explains that it's the result of a hormone imbalance, and that often — but not always — PCOS causes cysts to form right on the ovaries. 
These cysts aren't harmful, but they do lead to hormone imbalances that can cause infrequent or prolonged menstrual periods, excess hair growth, acne and obesity. It's also important to get a diagnosis of PCOS early on so it doesn't lead to long-term complications like type 2 diabetes and heart disease.

What causes PCOS?
Doctors don't know what exactly causes polycystic ovary syndrome, but the Mayo Clinic says there are a few theories about certain risk factors:
- Excess insulin: Too much insulin might affect the ovaries by increasing androgen production (male hormones), which could ultimately interfere with the ovaries' ability to ovulate correctly. 
- Low-grade inflammation: Studies have shown that women who have PCOS also have low-grade inflammation, which causes polycystic ovaries to produce androgens.
- Heredity: PCOS can run in families, so if your mother or sister has it, you have a greater chance of getting it, too.
Symptoms
The signs and symptoms of polycystic ovary syndrome start soon after a woman begins her period, but PCOS can also develop during the later reproductive years. There are many signs to look out for; however, individuals might be affected differently, and the symptoms worsen with obesity. 
The Mayo Clinic and WebMD say you should look out for the following symptoms:
1. Irregular menstrual cycles 
This is one of the most common signs of PCOS. Some examples include periods that are on a 35-day or longer cycle, fewer than eight periods a year, long or heavy periods and a failure to menstruate for four months or longer. 
2. Excess facial and body hair
You might find increased hair growth on your chin, chest, back, stomach and even toes.
3. Moodiness 
You might experience depression or mood swings that seem out of character.
4. Acne
PCOS can also cause acne or very oily skin. Pimples might be very deep and painful.
5. Insulin-level issues
Excess insulin interferes with the ovaries' ability to ovulate correctly. 
Treatment
 
Treating PCOS is different for everybody. Your doctor may prescribe lifestyle changes like diet and exercise to help lose weight. Your doctor might also prescribe birth control to help regulate your period and to decrease androgen production.

Each patient is different, though, so if you recognize any of the symptoms, you should talk to your doctor to get a diagnosis and learn the best way to treat your PCOS and symptoms.
