Coffee Can Make You Poop, But Is It Good For Constipation?
When it comes to coffee, the health consensus can be mixed. Some praise the drink for its brain benefits, healthy antioxidants, and performance-enhancing abilities. For others, coffee can lead to gut issues, such as heartburn, acid reflux, and stomach pain. But how does coffee affect digestion—and more specifically, constipation?
Can coffee help with digestion?
"It's likely that coffee consumption induces the gastrocolic reflex," integrative medicine doctor Alejandra Carrasco, M.D., tells mbg. The gastrocolic reflex is a physiological response, which induces movement of the lower gastrointestinal (GI) tract.
In other words, coffee stimulates movement through the digestive tract and makes you want to poop. While researchers aren't clear exactly why coffee increases digestion, it's clear that it does. "The warm temperature of the liquid1 may stimulate motility," integrative gastroenterologist Marvin Singh, M.D., previously told mbg, "and the caffeine also contributes to contractions of the bowel2."
What about caffeine versus decaf?
Chemicals in both caffeinated and decaf coffee, like chlorogenic acids, may contribute to the digestive process and stimulation of the bowel, Singh says.
So, is coffee a solution for constipation?
While coffee can certainly enhance digestion, it's not a long-term solution to constipation. Persistent constipation could be a sign of another health issue, like hypothyroidism, Carrasco says.
Other underlying gastrointestinal issues may include irritable bowel syndrome (IBS), Crohn's disease, or ulcerative colitis, which can all be exacerbated by the acidity in coffee, registered dietitian Nour Zibdeh, M.S., RDN, writes for mbg.
