Migraine nausea: your brain, your gut, and why they’re connected

A guide to understanding why nausea happens during a migraine attack, which types bring it on, and how to find some relief

Migraine is more than a headache. For many people, the nausea that comes with an attack is just as hard to deal with (and sometimes even harder) than the pain itself. It can make it impossible to eat, move, or function, and it often lingers long after the worst of the attack has passed.

According to Migraine Buddy data, 82% of users report nausea as a symptom during a migraine attack, and 32% report vomiting.

Understanding what is happening in your body and why can help you respond faster and feel less at the mercy of your own nervous system.

What happens in your body

Migraine nausea has its own neurological roots. It is not a byproduct of pain.

During a migraine attack, the trigeminal nerve system activates and sends pain signals from the blood vessels and membranes around the brain toward the brainstem. These signals arrive near the centers that control nausea and vomiting. The signals spill over, and the nausea response gets triggered. [1]

At the same time, serotonin levels fluctuate during a migraine attack. Because serotonin receptors are found throughout the gut as well as the brain, these fluctuations directly affect the digestive system slowing down stomach emptying in a process called gastroparesis. [2]

This slowing of the stomach, known as gastric stasis, is common in people with migraine, both during and between attacks. [3] It can leave you feeling full, bloated, and nauseous even when you haven’t eaten. It also makes oral medication harder to absorb, which matters when you’re planning your attack response.

Not only with headache: nausea & different attack phases

Before the headache (prodrome)

The prodrome is the warning phase that can begin hours before pain sets in. Among the most commonly reported prodrome symptoms is nausea, which tends to appear roughly 45 minutes to an hour before headache onset. This is one of the earliest warning signals the body sends. [4] Catching it early can be a cue to act before the attack fully takes hold.

During the aura phase

A 2012 study found that 51% of migraine attacks studied included nausea during the aura phase, [5] which means it can overlap with visual or sensory symptoms before the headache even begins.

During the headache phase

This is when nausea tends to be most intense. According to the American Migraine Foundation, nausea may occur during the headache stage, which can last anywhere from 4 to 72 hours. [5]

After the headache (postdrome)

The attack isn’t always over when the pain fades. Nausea is among the symptoms that can persist into the postdrome phase, when people are recovering from the attack. [6]

Which types of migraine attacks bring nausea

• Migraine without aura, the most common type. Nausea is one of its hallmark symptoms alongside sensitivity to light and sound. [7]
• Migraine with aura. In a study of migraine attacks with typical aura, nausea was present during the headache phase in 62% of attacks. [8]
• Vestibular migraine. Dizziness and balance problems are the main symptoms, but intense nausea and vomiting often follow from the vestibular disturbance. [7]
• Hemiplegic migraine. Nausea is a common accompanying symptom alongside temporary motor weakness and other aura symptoms. [7]

In short: nausea can be part of any attack type, regardless of which kind you experience.

What you can do about it: coping with nausea

There’s no single fix, but you can try these several approaches to help yourself if nausea is a common symptom of your migraine attacks.

Rescue plan during an attack

• Go somewhere dark and quiet. Sensory stimulation makes nausea worse. Removing it gives your nervous system room to settle.
• Try ginger. Ginger has anti-inflammatory and anti-nausea properties. Clinical studies have found that ginger can improve migraine symptoms, including nausea, within two hours. [9] Ginger tea, capsules, or candied ginger are all options.
• Test acupressure. Research has found that acupressure can decrease migraine-related nausea. [10] Two points to try: the P6 point on the inside of the wrist (about three finger-widths below the palm), and the LI-4 point in the fleshy space between the thumb and index finger.

• Sip cold water or an electrolyte drink. Small, slow sips tend to sit better than drinking at a normal pace. Staying hydrated also helps the body process the attack.
• Eat small and bland. If you can eat at all, plain foods like crackers, toast or plain rice are easier to tolerate than anything rich or heavily seasoned.
• Consider non-oral medications. Because gastric stasis can slow the absorption of oral medication during an attack, doctors sometimes recommend alternative routes (such as nasal sprays or injections) for people who vomit frequently during attacks. [11]

Talk to your doctor about anti-nausea medication

If nausea is a regular and disabling part of your attacks, bring it up with your neurologist or doctor. Anti-nausea medications such as metoclopramide or domperidone are sometimes prescribed alongside migraine treatments. Metoclopramide also helps speed up gastric emptying, tackling part of the underlying mechanism directly. [11]

Track your patterns

Logging your symptoms in Migraine Buddy can help you see when nausea tends to hit, how long it lasts, and whether certain triggers seem to make it worse. Over time, that data can be useful to share with your doctor for better treatment and can help you plan your attack response.
