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 increased levels of estrogen and progesterone. These hormones can cause swelling in the blood vessels around the head and neck, which can lead to tension headaches. Other potential triggers for headaches during pregnancy include lack of sleep, stress, dehydration, and certain foods or smells. To help prevent headaches, try to get plenty of rest, drink lots of fluids, and avoid triggers like caffeine, alcohol, and smoking. Additionally, consider taking over-the-counter pain relievers such as ibuprofen or acetaminophen if needed.
