Nausea And Headache: Causes And Prevention Methods

Headaches are very common and most people will experience one from time to time. They are manifested with pain or discomfort in or around your head, including your scalp, neck, or sinuses. However, sometimes a headache may be accompanied by nausea, which is the feeling of needing to vomit, and a number of health issues can be a cause to this.

Nausea and headache are very common symptoms, which can range from mild to severe. Even though there are many factors which can trigger nausea, for example, food poisoning, stress, anxiety, etc., headaches may affect nauseous feelings as well.

Despite not being able to give an exact answer to why certain types of headaches cause nausea, many researchers and physicians believe that headaches trigger nerves in the brain that make blood vessels in the brain enlarged. These nerves are connected to bodily signals that lead to nausea. While other studies have associated low levels of serotonin and changes in estrogen levels to headache-related nausea.

However, to gain a deeper insight into the relation between nausea and headache, let’s see what triggers them and how to prevent and treat these two symptoms.

Nausea and headache causes

There are many causes which trigger both nausea and headache, but the most common one is migraine, which is a recurring type of headache that can cause debilitating pain. Except for nausea, migraines can also cause other symptoms, including dizziness and sensitivity to light. Migraines are often preceded by a visual or sensory disturbance, called an aura.

According to Healthline, other conditions linked to nausea and headache include dehydration and low blood sugar. Dehydration occurs when you use or lose more fluid than you take in, whereas low blood sugar may develop for various reasons, including taking too much medication, excessive alcohol consumption, severe liver or kidney disease, hormonal deficiencies, and long-term starvation. Even diabetes can lead to low blood sugar, due to too much insulin intake.

Consuming too much alcohol, caffeine, or nicotine can also cause headache and nausea.

Other conditions that can lead to nausea and headache include:

– stress or anxiety

– food poisoning
– early pregnancy

When should you seek medical help?

Usually, mild to moderate episodes of nausea and headaches resolve on their own with time. For example, if they appear due to the common cold and flu, they will resolve without treatment.

– vomiting for more than 24 hours
– loss of consciousness
– dizziness
– confusion
– slurred speech
– neck stiffness and a fever
– no urination for eight hours or more

If your experiences with nausea and headache are mild, but however, occur on a frequent basis, it is still recommended to see a doctor so they diagnose your symptoms and recommend a treatment plan.
