What Can Cause Headaches and Nausea at the Same Time?

Experiencing a headache and nausea at the same time can be quite unsettling. It is likely to make you feel even more miserable than if you just have to deal with one condition or the other on its own.

This article will describe 12 potential causes of headaches and nausea at the same time and how to deal with symptoms.

It is important to see a doctor if you are experiencing a headache with nausea, especially if you are dealing with a sudden, severe headache and have no history of migraines. You need immediate medical attention if you experience a headache and nausea after a head injury. Your headache and nausea should not be accompanied by sporadic vomiting that lasts more than one day, dizziness, or confusion. Other troubling side effects are loss of consciousness, fever, and stiffness in your neck. Headache and nausea should not cause vision problems or trouble speaking or make you unable to urinate for more than eight hours.


There are many potential causes for having a headache and nausea at the same time. Certain types of headaches feature nausea as a related symptom. Some lifestyle habits can cause simultaneous headaches and nausea. Additionally, you may have headaches with nausea due to an underlying medical condition.

Three types of headaches can cause nausea as well:

  • Migraines
  • Dehydration Headaches
  • Cluster Headaches

Migraines are the most common type of headache that features nausea. Migraines cause a sharp, severe pain that has a pulsating or throbbing feeling. Migraines usually only affect one side of your head.

As the name implies, dehydration headaches are caused by dehydration. Dehydration occurs when your body does not have adequate fluids.

Cluster headaches are a sudden, severe series of multiple headaches. These headaches occur every day or nearly every day for weeks, months, or even years. Cluster headaches typically affect only one side of your head. They cause burning and piercing pain that starts around your eye and spreads to your face and forehead.

Lifestyle Habits

Alcohol can provoke migraines, and hangovers can cause both headaches and nausea.

If you are accustomed to drinking caffeine regularly, not getting your usual amount can cause headaches and nausea.

Nicotine increases your pain sensitivity and causes blood vessels to become narrow, which makes it harder to get proper blood flow to your brain.

Health Conditions

There are a number of underlying health conditions that may be at fault.

Low blood sugar (hypoglycemia) is caused by skipping meals or not eating enough. Hypoglycemia can cause headaches and nausea.

Headaches and nausea are common medication side effects of prescription and over-the-counter medications. Taking too many pain relief medications can cause medication overuse headaches.

If you experience frequent or severe stress or anxiety or have an anxiety disorder, you are more likely to develop migraines. Stress and anxiety can also weaken your immune system and increase your chances of developing diseases that cause headaches and nausea.

Infections or illnesses such as the flu, the common cold, or the stomach flu (gastroenteritis) can cause headaches paired with nausea. Tonsillitis, which inflames your tonsils, can also cause these symptoms.

Food allergies, such as wheat and corn, dairy, and grains, could be at the center of your headaches and nausea.

Hypertension can cause headaches and nausea if your blood pressure gets extremely high. This condition requires immediate medical attention.

Low blood sodium (salt) causes hyponatremia, which leads to side effects similar to those associated with dehydration.

Food poisoning happens when you eat or drink something contaminated with bacteria or viruses. This condition can cause nausea and dehydration, which can set off headaches.

Covid-19 can cause a wide variety of symptoms, but nausea and headaches are among the most common. These symptoms can range from mild to severe.


Being relaxed and well-rested can prevent headaches. Try to take a nap in a dark, quiet room if you have a migraine.

Practicing stress management techniques such as breathing exercises, muscle relaxation exercises, and listening to soothing music can help relieve your headaches and nausea.

Biofeedback helps you monitor the level of tension in your body. This can help you notice symptoms arising and help you manage them.

Drinking water can fight off dehydration. Staying well-hydrated on a regular basis can reduce the frequency of your headaches.

Eating a bland diet can reduce headaches, pain, and nausea. You should consider eating eggs, pudding, and custard.

Over-the-counter pain medications such as ibuprofen and acetaminophen can also reduce your symptoms.

Another treatment method that can target both nausea and headaches is IV (intravenous) vitamin therapy. It is a natural treatment that offers fast-acting relief for multiple types of headaches. This type of therapy will rehydrate you and can also increase your energy levels, improve your mood, and help you relax.

Knowing what type of headache you have and why it is accompanied by nausea will allow you to seek treatment and get better faster.
