Lactose intolerance
Lactose intolerance is a common condition where the body struggles to digest lactose, a sugar found in milk and dairy products. Symptoms typically include bloating, diarrhoea, stomach cramps, and flatulence, which usually occur within a few hours after consuming lactose-containing foods.
To manage lactose intolerance, various treatments are available. Many individuals find relief by reducing or eliminating dairy from their diets. Lactose-free products are also widely available, allowing those affected to enjoy dairy without discomfort. Additionally, over-the-counter lactase enzyme supplements can help break down lactose when taken before meals.
To determine if you have lactose intolerance, your doctor may recommend a few tests. The most common include the hydrogen breath test, where you breathe into a device to measure hydrogen levels after consuming a lactose-rich drink, and the lactose tolerance test, which checks blood glucose levels after lactose ingestion.
Lactose intolerance can be caused by a deficiency in lactase, the enzyme responsible for breaking down lactose. This deficiency can be genetic or develop over time, particularly in adulthood, as some people naturally produce less lactase as they age.
