Caffeine is a common substance that many people ingest on a daily basis without even realizing it. However, caffeine can produce some unpleasant side effects in the body, especially if you consume too much. If you notice a bloated belly and digestive upset after your morning cup of coffee, it may be due to the caffeine content.
Caffeine Sources
Caffeine is present in a variety of foods and products. Coffee and tea are the most obvious sources, but it's also naturally included in chocolate. Caffeine is added to products as well, including pain killers, energy drinks and nutritional supplements.
Digestive Effects
Consuming caffeine can cause some digestive upset, including pain and diarrhea, according to MayoClinic.com. Though gas isn't a typical side effect, it can occur if you take in an irritating substance that contains caffeine, like coffee. Coffee is acidic and can make you gassy.
Sensitivity or Allergic Response
Though caffeine can upset your stomach, if you experience severe gas, you may have a food sensitivity or allergy not to the caffeine but rather to something the caffeine is in, such as milk, wheat or soy. If you have a sensitivity or allergy, your body will react through inflammation of your digestive tract. This causes bloating, gas, constipation, diarrhea and, in some cases, external symptoms like rashes or throat swelling. If you suspect you have a food allergy, contact your doctor immediately.
Prevention and Precaution
If you notice that drinking coffee or consuming some other product that contains caffeine causes you digestive upset like intestinal gas, you can prevent future suffering by reducing your intake of caffeine or discontinue use altogether. If you have severe abdominal cramping or blood in your stool, see a doctor immediately for a prompt diagnosis.
