Final answer:
Lactose intolerance is a digestive condition characterized by the inability to digest lactose, leading to symptoms such as bloating, flatulence, and diarrhea.
Step-by-step explanation:
Lactose intolerance is a widespread digestive condition where individuals cannot fully digest lactose, a sugar found in milk and dairy products. This happens due to a deficiency in lactase, an enzyme produced by the absorptive cells in the small intestine, which is responsible for breaking down lactose into glucose and galactose. Lactose intolerance can lead to symptoms like lactic acidosis, bloating, flatulence, indigestion, and gastrointestinal discomfort. When lactose is not digested, it reaches the large intestine where it is fermented by gut bacteria, leading to the production of gas and other byproducts that cause the uncomfortable symptoms mentioned.
People with this condition typically experience a range of symptoms, that can include watery diarrhea, stomach cramps or pain, bloating, increased gas, nausea, and sometimes indigestion after consuming dairy products. The severity of these symptoms can vary from mild discomfort to severe pain. Treatment often involves dietary adjustments to reduce or eliminate the intake of lactose-containing foods and the use of lactase enzyme supplements.
While lactose intolerance is not typically dangerous, it can cause significant discomfort and a decrease in quality of life for those affected. It is important to distinguish the symptoms of lactose intolerance from other potential causes of gastrointestinal distress to ensure appropriate management and care.
