Headaches are a pain—literally. But when you’re pregnant, that pounding in your head can come with extra worries. If you’ve been wondering what causes headaches during pregnancy, how to handle them, and when to call your doctor, you’re in the right place.
Why Do Headaches Happen?
Headaches are incredibly common, especially for women in their childbearing years. In fact, one study found that 60% of women under age 40 had a headache in the past year. For pregnant women, headaches can be triggered by hormonal shifts, stress, poor sleep, hunger, dehydration, or even the extra weight and posture changes from a growing baby.
If you’ve had headaches before pregnancy, like migraines or tension headaches, you might find they improve, get worse, or stay the same. It’s all part of your body’s unique reaction to pregnancy hormones.
Red Flags: When to Worry
Not all headaches are created equal. Some can signal something serious, especially if you’re over 20 weeks pregnant. A headache could be a sign of preeclampsia, a condition involving high blood pressure that can harm both mom and baby ( https://montanaobgyn.com/understanding-preeclampsia-a-comprehensive-guide/ ). Here’s when to call your doctor:
- Severe, constant headaches that won’t go away.
- Headaches with blurry vision, light sensitivity, or confusion.
- Headaches paired with upper belly pain, nausea, or swelling in your hands and face.
- Any new, sudden, or unusual headache.
Common Types of Headaches
- Tension Headaches: These feel like a tight band around your head. They’re often triggered by stress or poor posture.
- Migraines: These are typically one-sided and pulsating, often accompanied by nausea, vomiting, or sensitivity to light and sound. They might improve during pregnancy for some women who struggled with them prior to pregnancy.
- Cluster Headaches: These are rare but intense, focused on one side of the head, often around the eye.
Safe Ways to Manage Headaches
Good news: most headaches during pregnancy aren’t dangerous and can be treated safely. Here are some tips:
- Hydrate: Dehydration can be a major trigger. Keep a water bottle handy. https://montanaobgyn.com/the-importance-of-hydration-during-pregnancy/
- Snack Smart: Low blood sugar can cause headaches, so eat small, regular meals.
- Get Rest: Lack of sleep can make headaches worse, so prioritize rest.
- Heat or Ice: Apply a warm or cold compress to your head or neck.
- Relax: Stress management techniques like yoga, deep breathing, or meditation can help.
- Watch Your Posture: Maintaining good posture can help alleviate headaches.
- Visit a Chiropractor: A chiropractor might provide relief from pregnancy-related headaches.
- Consult a Dentist: Headaches sometimes originate from dental issues, so a visit to the dentist could help.
- Avoid Certain Foods: Some foods can trigger headaches, so be mindful of potential culprits.
- Over-the-Counter Relief: Acetaminophen (Tylenol) is usually safe for headaches during pregnancy, but always consult your healthcare provider first.

When Medications Are Needed
Sometimes, lifestyle changes aren’t enough. If your headaches persist or become severe, your doctor might recommend safe medications. Some options include:
- Acetaminophen (Tylenol): The go-to choice for many pregnant women.
- Metoclopramide or Promethazine: These can help if nausea accompanies your headache.
- Sumatriptan: This migraine-specific drug may be used if other treatments fail.
Your doctor will weigh the benefits and risks to ensure both you and your baby are safe.
Postpartum Headache
Headaches don’t always stop after delivery. The postpartum period is full of potential triggers like sleep deprivation, hormonal shifts, and stress. Additionally, epidurals or spinal anesthesia can cause a specific type of headache called a postdural puncture headache. This headache is typically better when lying flat and worse when sitting up or walking. It often improves with rest or a procedure called a blood patch, where a small amount of your blood is injected near the spinal area to seal the puncture and relieve the headache.
Managing postpartum headaches involves addressing the underlying cause, staying hydrated, getting as much rest as possible, and consulting your healthcare provider if symptoms persist or worsen.
Final Thoughts
Most headaches during pregnancy are nothing to worry about, but they can still disrupt your day. Focus on prevention with good hydration, nutrition, and stress management. And remember, if something feels off, trust your instincts and call your healthcare provider.
Pregnancy is full of changes, and your body is working overtime. Don’t hesitate to give yourself a little extra care when your head starts pounding—you’ve earned it!
