📖 1. Lactase Deficiency

🔑 Key Concepts & Definitions

• Lactase deficiency: A condition characterized by the insufficient activity of the enzyme lactase in the small intestine, leading to an inability to digest lactose properly (source content).
• Symptoms after dairy intake: Clinical manifestations such as abdominal pain, spasms, nausea, and diarrhea that occur following consumption of dairy products, due to undigested lactose fermenting in the gut (source content).
• Osmolar diarrhea due to lactase deficiency: Diarrhea caused by the osmotic effect of unabsorbed lactose in the intestinal lumen, which draws water into the bowel, leading to increased stool volume and liquidity (source content).
