Hi Dr. I am turning 22 years old next month, I have never had sex, I am overweight and had never had any problems; but now I am worry because I have missed my period now 4 months...I was told it could be hormone inbalance and/or that is due to my overweight. I am 5 10 ht and wt. 245 lbs. my bone is large structure. On my last physical exam all came out ok. my sugar, cholesterol, etc. Only a few points more of the testerone for which gyn told me it had to do with my overweight. Again, nothing has changed I eat the same, I sleep the same, but my period stopped. What can do? Thank you.
