Alcohol and caffeine are the two most common food-related triggers for migraine headaches, according to the National Pain Foundation. A migraine headache is often mistaken for a sinus headache because of similar symptoms, according to MayoClinic.com. One of the most significant differences between a sinus headache and a migraine headache is the nausea and vomiting that sometimes accompany migraines.
About Migraines
Migraine headaches are chronic headaches that result in severe throbbing pain throughout the head. Migraines can cause a person to try to avoid loud noises, bright lights and other activities. Migraine headaches are triggered by foods, exercise and changes in sleep patterns, according to MedlinePlus. Although the exact cause of migraines is still unknown, most medical professionals believe it is related to changes in the blood vessels of the brain.
Alcohol
Alcohol is one of the most common food-related triggers for migraines and other types of headaches. Red wine is the primary culprit. Alcohol is considered a diuretic that depletes the body of water. Ingredients in wine that are believed to trigger headaches are histamine, sulfites and tyramine. Histamine foods include beer, wine and pizza.
Caffeine
Caffeine is commonly found in coffee, sodas and chocolate. Caffeine is a substance that can either help alleviate headache pain or cause it, according to the National Pain Foundation. Caffeine also is found in over-the-counter pain relievers because of its natural ability to dilate the blood vessels in the brain. Too much caffeine, or caffeine withdrawal, can lead to severe headaches, including migraines.
Symptoms
Migraine headache symptoms caused by consuming alcohol and caffeine can include loss of appetite, severe head pain, eye pain, tunnel vision, chills, nausea, vomiting, sweating, sensitivity to light and noises. Migraine headaches produce different symptoms in different people. If you have constant head pain, consult a physician.
Treatment
The most common treatment for headaches caused by alcohol and caffeine are over-the-counter pain relievers. These medications can help treat and prevent the pain from getting worse. Taking a nonsteroidal anti-inflammatory drug at the first sign of head pain can help prevent a severe migraine attack.
