Why Does Coffee Upset Some People’s Stomachs?

According to SHAHEDNEWS, Coffee can impact the digestive systems of some individuals. This article explores why coffee might upset your stomach.

Why Coffee May Upset Your Stomach

Compounds in Coffee That Can Trigger Digestive Issues

Caffeine
Caffeine is a natural stimulant that helps you stay awake. A standard 240 ml cup of coffee contains about 95 mg of caffeine.

While caffeine is a powerful mental stimulant, studies indicate that it can increase contractions throughout the digestive tract.

For instance, a 1998 study found caffeinated coffee stimulated the colon 23% more than decaffeinated coffee and 60% more than water. This suggests caffeine significantly stimulates bowel movements.

Additionally, caffeine may boost stomach acid production, potentially upsetting sensitive stomachs.

Coffee Acids
Although caffeine is often blamed for coffee-related stomach issues, research shows coffee’s acids also play a role.

Coffee contains acids like chlorogenic acid and N-alkanoyl-5-hydroxytryptamine, which increase stomach acid production. While stomach acid aids in food breakdown, it can exacerbate symptoms like heartburn for some individuals.

Still, studies on this are inconclusive and have not found a definitive link between coffee and heartburn symptoms.

Additives
Sometimes, it’s not the coffee itself but the additives like milk, cream, sweeteners, or sugar that upset your stomach.

For example, about 65% of the global population cannot properly digest lactose—the sugar in milk—which can cause bloating, stomach cramps, or diarrhea shortly after consumption.

Can Decaffeinated Coffee Also Upset Your Stomach?

Switching to decaffeinated coffee may help alleviate stomach issues for individuals sensitive to caffeine.

However, decaf coffee still contains coffee acids like chlorogenic acid, which can increase stomach acid and trigger gastrointestinal contractions.

Additionally, additives like milk, cream, or sugar can still cause digestive discomfort if your body is sensitive to them.

Tips to Prevent Coffee-Related Stomach Upset

• Drink Gradually: If you’re new to coffee, start with small sips to help your stomach adjust.

• Avoid Drinking Coffee on an Empty Stomach: Since coffee is acidic, pairing it with food can ease digestion.

• Try Plant-Based Milk: If you’re lactose intolerant or suspect milk causes discomfort, switch to plant-based alternatives like almond or soy milk.

By following these tips, you can reduce the chances of stomach upset and continue enjoying your coffee.
