The problem is that i haven't had a period in around a year. i'm 23, not on birth control, and have been diagnosed with pcos. is this typical?

PCO: yes. Very common. Has your treating healthcare provider started you on medicine. Metformin and birth control are used very commonly to treat this condition along with spirinolactone. Be sure to discuss treatment options with your healthcare provider. Hope this helps. Best of luck Dr R

It is typical : If you have PCOS you do not ovulate much at all, if ever. Without ovulation there is no period although there can be irregular bleeding from time to time. See your GYN for treatment options. One thing that helps enormously is exercise and weight loss. It is often possible lose enough weight to start ovulating on your own without meds.

Lets review your que: Menses in PCOS is vary irregular and infrequent. Follow up with your gynecologist. since patients that don't ovulate have a 3 times higher chance of developing uterine cancer. You are more likely to develop diabetes so I would be followed by a primary care physician as well.

No period for a year: PCOS commonly causes menstrual cycle irregularity, but there are a number of other causes that can occur in women with or without PCOS. A pregnancy test is important, especially for women who are not using birth control. If periods used to be more frequent then stopped for one year, the change in pattern might mean additional hormone tests are needed to find out the cause.

PCOS: PCOS is a condition which usually inhibits ovulation, and since ovulation is required for a menstrual period to follow ( if pregnancy does not intervene) it is common for those women correctly diagnosed with PCOS to go for long periods of time without menses. Ask your health professional about oral contraceptives. Long term estrogen only can affect the uterus negatively, and oral BCP's stop this.
