Frequent late menstruation, sometimes up to 3 weeks late. Could this be a sign of illness?

Question

I am asking the question for my girl-friend. She is 22 years old and not over weight.

Answer 1

It could be a sign of illness, like poor nutrition, hyperthyroidism, or stress, or PCOS, or peri-menopause.  Really, there could be a lot of reasons for having late periods, but you really should go see your doctor as some reasons may tell you that you need to have a child now if you want one, or make some changes in your life if you want to remain healthy, or have some things happen to return you to normal.

Answer 2

If your overweight alittle that can affect periods.  I had problems with ovarian cysts, and that caused late and missed periods.  I had to go on birth control for 3 years, and then when I came off of it, I didn't have the problems anymore.  Talk to your doctor the next time your there.  Have you had a recent pap?
