Headaches are a common occurrence during pregnancy, affecting more than 90% of expecting mothers. The reasons may vary, such as hormonal changes, increased blood volume, or low blood sugar, among others.

However, some headaches may be a sign of a more severe health condition that requires medical attention. In this article, we will discuss when to worry about headaches during pregnancy.

Types of headaches during pregnancy

Before diving into the red flags to watch out for, let’s explore the different types of headaches that you may experience during pregnancy.

Tension-type headaches

Tension-type headaches are the most common type of headache and can affect anyone, not just pregnant women. It feels like a mild-to-moderate pain or pressure sensation on both sides of the head around the forehead area.

Migraine headaches

Migraines follow a typical pattern of a throbbing headache on one side of the head accompanied by nausea, vomiting, and sensitivity to light and sound. The pain can last anywhere from four to 72 hours.

Sinus headaches

Sinus headaches occur when the cavities around the nasal passages become inflamed and congested, causing pain and pressure around the cheeks, forehead, and nose. It often accompanies a stuffy nose and fever.

When to worry about headaches during pregnancy?

While most headaches during pregnancy are entirely harmless, some may be a sign of a severe condition that requires immediate medical attention. Here’s when you should worry about your headaches:.

1. Severe headaches

If you have never experienced a headache as simple as tension headaches or migraines suddenly, especially if it’s accompanied by a stiff neck, fever, blurred vision, or sudden swelling in the face or hands, it could be a red flag for preeclampsia.

Preeclampsia is a pregnancy-specific disorder that affects blood pressure and requires immediate medical attention. This condition generally occurs after 20 weeks of pregnancy and can be fatal if left untreated.

2. Headaches accompanied by visual disturbances

Headaches associated with symptoms like blurred vision, double vision, sensitivity to light, or changes in vision could be a red flag for other pregnancy-specific health issues like gestational diabetes or hypertensive disorders like gestational hypertension.

3. Headaches lasting for an extended period

Headaches lasting for more than four hours or that don’t respond to acetaminophen (Tylenol) or other over-the-counter pain relief medications should be evaluated by your healthcare provider.

4. New onset of migraine headaches during pregnancy

If you have a history of migraine and noticed that you’re having more frequent or more severe migraine attacks, speak with your healthcare provider for guidance and appropriate treatment as migraines can increase the risk of a severe headache disorder called Reversible Cerebral Vasoconstriction Syndrome (RCVS).

Ways to prevent headaches during pregnancy

The good news is that not all headaches are inevitable! There are specific steps you can take to prevent headaches from occurring during pregnancy. Some of them include:.

1. Stay hydrated

Dehydration is one of the most common triggers of headaches. Pregnant women require more fluids than non-pregnant women, and drinking plenty of water, fresh juice, or herbal tea can help stave off headaches.

2. Get proper rest

The physical and emotional demands of pregnancy can lead to fatigue, which is another significant headache trigger. Getting enough sleep and balancing rest/nap breaks can help alleviate headaches and keep them at bay.

3. Exercise

Engaging in physical activity regularly can help reduce stress levels and tension in the muscles, which are common headache triggers.

However, it’s crucial to consult your healthcare provider before starting a new exercise routine during pregnancy.

Conclusion

Headaches are a common occurrence during pregnancy, and while most of them are entirely harmless, a few may signal a more severe condition that needs prompt medical intervention.

If you’re experiencing any severe or unusual headaches, speak with your healthcare provider and get the appropriate treatment and attention you need to ensure a healthy pregnancy.
