Why does only vanilla coffee make your stomach hurt?

It's unlikely that only vanilla coffee would specifically cause stomach upset. Here's why:

* Vanilla itself is unlikely the culprit. Vanilla is a natural flavoring agent, generally considered safe for consumption. It's unlikely to be the cause of stomach pain unless you have a specific allergy.

* It's more likely related to other factors in coffee. Stomach issues with coffee could be due to:

* Caffeine: Caffeine is a stimulant that can irritate the stomach lining, especially in sensitive individuals.

* Acidity: Coffee is naturally acidic, and this can contribute to heartburn or indigestion in some people.

* Other ingredients: If you're adding cream, sugar, or other additives to your coffee, these could be contributing to your stomach pain.

Possible reasons you might experience stomach pain with vanilla coffee:

* The brand you use: Different coffee brands use varying roasts, brewing methods, and additives, which could affect your stomach.

* The brewing method: Strong brews or over-extracted coffee can be more acidic and harder on the stomach.

* Your own sensitivity: Some people are more sensitive to caffeine or acidity than others.

To figure out why your vanilla coffee is causing stomach upset, try:

* Eliminating caffeine: Try decaffeinated coffee to see if that helps.

* Reducing acidity: Try brewing coffee with a lower acid content, or adding a teaspoon of baking soda to your coffee.

* Adjusting your diet: Pay attention to what you eat before and after drinking vanilla coffee. Certain foods can exacerbate stomach issues.

* Talking to your doctor: If your stomach pain persists or is severe, it's always best to consult a healthcare professional.

Remember, it's important to listen to your body and identify the specific triggers that cause you discomfort.
