What causes PCOS?

Doctors don’t know what exactly causes polycystic ovary syndrome, but 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.


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.

You should look out for the following symptoms:

1. Irregular menstrual cycles

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.
