I've heard that a lot of people get a lot of headaches when they're pregnant. What are the causes and how can I prevent them?

The most common cause of headaches during pregnancy is hormonal changes, such as those caused by increased levels of progesterone and estrogen. Other factors that may contribute to headaches include stress, fatigue, lack of sleep, certain foods or drinks, and physical discomfort from swelling or pressure on your head. To help reduce the frequency and intensity of headaches, try getting plenty of restful sleep each night, avoiding caffeine and alcohol, eating healthy meals, and exercising regularly. Additionally, you can talk to your doctor about medications that might be safe for use during pregnancy.
