Lactase Deficiency (Loc283332): A Comprehensive Guide
Description
Lactase deficiency is a condition where the body produces insufficient lactase, an enzyme responsible for breaking down the milk sugar lactose into digestible components. This results in an inability to properly digest lactose-containing foods, leading to various health issues.
Symptoms
The primary symptoms of lactase deficiency include:
- Abdominal pain
- Bloating
- Diarrhea
- Gas
- Nausea
- Vomiting
These symptoms typically occur within 30 minutes to 2 hours after consuming lactose-containing foods.
Associated Diseases
Lactase deficiency can be associated with certain medical conditions, such as:
- Inflammatory bowel disease (IBD): Crohn's disease and ulcerative colitis can damage the lining of the small intestine, leading to reduced lactase production.
- Celiac disease: An autoimmune condition that attacks the small intestine, also affecting the production of lactase.
- Bacterial overgrowth: An excessive presence of bacteria in the small intestine can interfere with lactase activity.
Did you Know ?
Lactase deficiency affects approximately 65% of the global population, varying significantly among different ethnic groups. Prevalence is highest in East Asians (90-100%), followed by South Asians (60-80%), Europeans (30-50%), and Africans (20-40%).
Diagnosis
Lactase deficiency is typically diagnosed through:
- Hydrogen breath test: This test measures the amount of hydrogen gas produced in the breath after consuming a lactose solution.
- Stool acidity test: This test measures the acidity of stool samples, which can be elevated in the presence of undigested lactose.
Management
Individuals with lactase deficiency can manage the condition by:
- Avoiding lactose-containing foods: This includes dairy products (milk, cheese, yogurt) and foods that contain hidden lactose (e.g., baked goods, processed foods).
- Using lactase supplements: These supplements contain lactase enzyme that can be taken before consuming lactose-containing foods.
- Choosing lactose-free alternatives: Many dairy products and food items are now available in lactose-free versions.
