Many people notice an increased urge to use the bathroom after drinking coffee. Is this a mere coincidence, or does coffee truly have laxative properties—especially something to consider before an important meeting?
Caffeine in coffee is a well-known diuretic, which means it promotes urine production. This explains why some individuals need to urinate frequently after consumption, a normal physiological response best avoided before long activities like marathons.
For those with sensitive digestive systems, coffee can also stimulate contractions in the large intestine, mimicking the effect after a meal. Notably, decaffeinated coffee lacks this impact, pinpointing caffeine as the key factor.
Coffee's acidity boosts bile production in the liver, stored in the gallbladder. Caffeine can then trigger its release into the stomach, potentially leading to diarrhea. Added sugars or lactose may worsen these effects, prompting urgent bathroom visits.
To minimize risks, limit intake to 2-3 cups in close succession, advises the International Foundation for Gastrointestinal Disorders (IFFGD). Alternating with decaf is a smart strategy.
