Can coffee cause diarrhea?

Coffee can cause diarrhea as its constituents tend to have a laxative effect. Generally, most people drinking over two or three cups of coffee can cause diarrhea.

Other additives and ingredients such as milk, cream or sugar can make diarrhea worse.

Why does coffee cause diarrhea?

Caffeine, dairy products, and sweeteners in coffee have a laxative effect, which stimulates the digestive system.

If a person experiences symptoms like palpitations, anxiety, dizziness, insomnia and GIT discomfort, it could mean that you are experiencing caffeine sensitivity.
