Integrative gastroenterologist Marvin Singh, M.D., and functional medicine doctor Wendie Trubow, M.D., MBA, weigh in on why coffee often leads you to the bathroom and whether or not it’s possible to manage that bodily reaction. “Also there are chemicals in coffee like chlorogenic acids that may contribute to the digestive process and stimulation of the bowel,” Singh explains. Those acids are present in both caf and decaf varieties. But if you’re drinking the coffee later in the day, the temperature probably won’t make a difference. “The main thing you’re removing by making coffee iced is the temperature,” he says. “The acidic chemicals and other compounds in coffee may still contribute to having a bowel movement.” Additionally, if you’re sensitive to lactose, swapping your dairy creamer for an almond or oat milk alternative might help reduce gas and bloating. Unfortunately, Trubow says, “if you are responsive to coffee, it’s unlikely that you can stop the effects if you drink it.” If it’s bothersome enough, you might try swapping your coffee for tea or warm water with lemon.
