When it comes to coffee, opinions on health can be mixed. Some praise the drink for its brain benefits, healthy antioxidant qualities, and performance-enhancing properties. For others, coffee can lead to intestinal problems such as heartburn, acid reflux, and stomach aches. But, how does coffee affect digestion and more specifically constipation?
«It is likely that coffee consumption induces the gastrocolic reflex,» says Alejandra Carrasco, a doctor in integrative medicine. The gastrocolic reflex is a physiological response that induces movement of the lower gastrointestinal tract. In other words, coffee stimulates movement through the digestive tract and makes you want to go to the bathroom.
While researchers aren’t clear exactly why coffee boosts digestion, it’s clear that it does. «The warm temperature of the liquid can stimulate motility,» says integrative gastroenterologist Marvin Singh, «and the caffeine also contributes to bowel contractions.»
What about decaf coffee?
According to one study, both caffeinated and decaffeinated coffee can increase intestinal motility, but another study suggests that caffeinated coffee has greater effects. This study found that caffeinated coffee stimulated colon movement 23% more than decaffeinated coffee. Chemicals in decaffeinated and caffeinated coffee, such as chlorogenic acids, can contribute to the digestive process and stimulation of the gut, Singh says.
So, is coffee a solution for constipation?
While coffee can certainly improve digestion, it’s not a long-term solution to constipation. Persistent constipation could be a sign of another health problem such as hypothyroidism, Carrasco points out.
Other underlying GI issues can include irritable bowel syndrome (IBS), Crohn’s disease or ulcerative colitis, which can be aggravated by the acidity of coffee, writes registered dietitian Nour Zibdeh.
«I would recommend that people focus on proper hydration, daily fiber intake, and work with their doctor to make sure there isn’t a causal reason for the constipation,» Carrasco says.
Opting for less acidic versions of coffee can also be beneficial for the intestine, so you can enjoy a good cup in the morning and forget about the problems it can bring you. And does coffee benefit you or harm you?
