Why does wine cause migraines?

While it's not definitively understood why wine causes migraines in some people, several factors are thought to contribute:

1. Histamines:

- Some wines, especially red wines, contain higher levels of histamines, a compound that can trigger migraines in sensitive individuals.

2. Tyramine:

- Red wines can also contain tyramine, an amino acid that can constrict blood vessels and lead to headaches.

3. Sulfites:

- Sulfites are added to wine as preservatives, and some people are sensitive to them, experiencing headaches or other reactions.

4. Alcohol:

- Alcohol itself can trigger migraines in some people, as it can dehydrate and dilate blood vessels.

5. Other Compounds:

- Other compounds present in wine, such as tannins, can also contribute to headaches in susceptible individuals.

6. Individual Sensitivity:

- Migraine triggers vary from person to person. Some individuals may be more sensitive to specific compounds in wine than others.

7. Genetics:

- There may be a genetic predisposition to developing migraines after consuming wine.

8. Food Sensitivities:

- It's important to consider any food sensitivities you might have, as they can be triggered by certain wines. For example, some wines are aged in oak barrels, and people with oak allergies might experience headaches after consuming them.

9. Dietary Factors:

- Factors like skipping meals or dehydration can exacerbate headaches, making you more susceptible to migraines after consuming wine.

10. Stress and Lack of Sleep:

- Stress and lack of sleep can trigger migraines, making you more likely to experience them after drinking wine.

It's important to note that not everyone who drinks wine will get a migraine. The factors mentioned above are contributing factors, and the specific triggers and sensitivities vary from person to person.

If you experience migraines after drinking wine, it's best to talk to your doctor. They can help you determine the underlying causes and recommend ways to avoid or manage the headaches.
