"My boyfriend is lactose intolerant but continues to consume products containing it. What are the short and long term consequences?"

Consuming dairy products when lactose intolerant can have short-term effects such as intestinal inflammation and potential damage to the gut microbiome, leading to issues like diarrhea. In the long term, this can increase the risk of conditions like hemorrhoids and colitis. It is best to replace dairy products with lactose-free alternatives and consider taking lactase supplements before consuming lactose-containing foods.
