Final answer:
Lactose intolerance can cause gas when consuming milk and cheese. Symptoms include bloating, cramps, and diarrhea. Avoidance of lactose-containing foods or choosing lactose-free alternatives can help prevent gas.
Step-by-step explanation:
Lactose intolerance is a condition in which the lactose in milk cannot be digested well in the small intestine. The undigested lactose then moves into the large intestine where bacteria attack it, forming large amounts of gas. Symptoms of lactose intolerance include bloating, cramps, nausea, and vomiting.
Similarly, in people with lactose intolerance, the lactose in chyme is not digested. Bacteria in the large intestine ferment the undigested lactose, a process that produces gas. In addition to gas, symptoms include abdominal cramps, bloating, and diarrhea. Symptoms resolve once the lactose is eliminated in feces.
If you have lactose intolerance, avoiding foods containing lactose, such as milk and cheese, is recommended to prevent gas and other symptoms. There are also lactose-free alternatives available, such as lactose-free milk, which can be consumed without causing gas.
