Q: Can drinking wine cause constipation?—Emmett, Dublin

A: Moderate wine consumption has been linked to many potential gastrointestinal health benefits. These include improved gut microbiota and even activity against harmful bacteria, including those that cause stomach ulcers. However, wine and other alcoholic beverages can also cause or exacerbate heartburn, bloating and other unpleasant conditions. Is constipation one of them?

How Does Alcohol Affect Digestion?

Dr. Rami El Abiad and Dr. Mohamad Mokadem, gastroenterologists at the University of Iowa Hospitals and Clinics, told Wine Spectator that “most social drinkers who consume alcohol in moderation will almost never experience any digestive issues,” including constipation.

Dr. Abiad and Dr. Mokadem stress that moderation is a key word here. “Consuming alcohol in excess, wine included, can adversely affect the digestive system.” They say alcohol’s diuretic effects can “potentially [lead] to dehydration, which can contribute to or worsen constipation.”

Since constipation is often closely associated with dehydration, it makes sense that alcohol’s dehydrating effects could cause or worsen bowel irregularities. Dehydration is also behind many of the unpleasant symptoms of hangover, which often involves gastrointestinal discomfort. Additionally, some studies suggest that alcohol, particularly in high concentrations, can actually inhibit the muscles of the intestines and slow bowel motility.

Risk of GI Tract Inflammation

Dr. Carol Murakami, a spokesperson for the American Gastroenterological Association, says that though “alcohol tends not to cause constipation,” it “can irritate or damage the lining of the gastrointestinal tract.” That, in turn, can cause “discomfort, nausea, vomiting and pain.” According to Dr. Murakami, “since acid is not involved in the irritation of the lining of the GI tract caused by alcohol, acid reducers do not prevent this from happening.”
