I am suffering from recurring headaches post pregnancy from last two years. Thyroid, BP ,CBC, eye sight all normal. What could be the reason?

A. Studies have shown that up to 39 percent of people experience headaches in the first week after childbirth. Commonly called postpartum headaches or postnatal headaches, sometimes these headaches can be due to changes in estrogen levels. After pregnancy, a woman's estrogen levels drop significantly.
