E73.9
Lactose intolerance, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
Lactose intolerance is a common digestive condition where the body cannot effectively digest lactose, a sugar found in milk and dairy products. This occurs due to a deficiency of lactase, the enzyme responsible for breaking down lactose in the small intestine. When lactose isn't properly digested, it can lead to uncomfortable gastrointestinal symptoms. Although it can develop at any age, lactose intolerance often appears during adolescence or adulthood. Recognizing its symptoms and causes can help manage the condition effectively.
Causes & Symptoms
Clinical Causes: Lactase enzyme deficiency: A decrease in lactase production can be natural with age or due to intestinal damage. Genetic factors: Some populations have a higher prevalence of lactose intolerance based on inherited traits. Injury or illness: Conditions like gastroenteritis, celiac disease, Crohn's disease, or other intestinal disorders can impair lactase production. Premature birth: Born prematurely, especially before the full development of the small intestine, can be associated with reduced lactase activity.
Key Symptoms: Bloating and gas: Excess gas production causes discomfort and abdominal distension. Diarrhea: Osmotic effects of unabsorbed lactose draw water into the intestines, leading to loose stools. Stomach cramps and pain: Cramping from gas buildup and intestinal activity. Nausea: Feeling sick after consuming dairy products. Flatulence: Increased intestinal gas results in frequent farting.
Diagnostic & Treatment
Diagnosis Path: Diagnosing lactose intolerance involves a combination of dietary history, symptom assessment, and specific tests. Common diagnostic methods include:
Treatment Protocols: While lactose intolerance cannot be cured, management strategies can help control symptoms effectively:
