Why does lactose intolerance cause diarrhea?

Abdominal cramps, nausea and diarrhea are all symptoms associated with lactose intolerance Lactose intolerance refers to the body's inability to digest lactose - a sugar found in dairy products Diarrhea due to lactose intolerance can lead to weight loss, dehydration and electrolyte abnormalities Lactose dyspepsia is related to intestinal biochemical level When lactose is digested, the small intestine must produce enough lactase Lactase is an enzyme responsible for the biochemical reaction of breaking down lactose into glucose molecules (absorbed by the body and used for energy) When there is not enough lactase to decompose lactose, lactose will accumulate in the digestive tract and cause lactose intolerance If the small intestine can produce a small amount of lactase, the body can tolerate a small amount of lactose Osmotic diarrhea can be caused by many reasons However, diarrhea caused by lactose intolerance is related to osmosis (or water movement between cells and tissues) Too much lactose in the small intestine attracts water molecules, preventing them from being properly absorbed into the bloodstream Therefore, reducing lactose intake can improve water absorption and solve diarrhea Too much gas lactose intolerance can not only cause diarrhea, but also produce too much gas Bacteria that ferment too much lactose in the large intestine produce a lot of gas As with diarrhea symptoms, reducing lactose intake can solve the problem of excess gas without special treatment It is suggested that if you want to prevent diarrhea, you must pay attention to your lactose intake It is recommended to drink 50-100g of dairy products to see how the body reflects Observe closely how much lactose your body ingests does not cause the limit of diarrhea In addition, products such as soymilk, goat milk, fermented milk products, cheese and lactose free milk can be used instead of milk products If lactose intolerance is serious, it is recommended to see a doctor for other gastrointestinal problems.
