What is the cause of headache after drinking beer

March 10, 2023
Everyone is different, and some people are fine after drinking beer, but others feel headaches, dizziness and other discomforts. What is this all about? The following will take you to learn more about it.

Insufficient blood supply to the brain

If you have a headache after drinking beer, it may be caused by a lack of blood supply to the brain. Drinking beer can cause a decrease in blood flow to the brain, which causes a large amount of lactic acid, oxygen ions, and potassium ions to accumulate in the brain and cause a headache.

Amine stimulation

Headaches after drinking beer may be caused by amine stimulation. Beer contains more amines, which stimulate the release of adrenaline from sympathetic nerve endings, and adrenaline can have a constricting effect on blood vessels and cause headaches.

Alcohol stimulates nerves

If you have a headache after drinking beer, it may be caused by the stimulation of nerves in the brain by alcohol. The acetaldehyde formed by the decomposition of alcohol can stimulate the autonomic nerves and cause the blood vessels to dilate and the muscles to atrophy, resulting in headaches.

High blood pressure

If your body has high blood pressure, you may also have a headache after drinking beer. Patients with high blood pressure should control their alcohol consumption. If the liver is functioning well, a small amount of alcohol consumption is possible.

Neurovascular headache

If you have a headache after drinking beer, it may be a neurovascular headache. This is a headache caused by abnormalities in the diastolic function of blood vessels in the head due to the stimulation of blood vessels by alcohol.
