Primary lactase deficiency develops when your lactase production decreases as your diet becomes less reliant on milk and dairy products.
Why is it important to study lactose intolerance?
Recent studies have provided important new insight into the complex relationship between lactase deficiency, lactose malabsorption and symptom generation. This work has shed light on the wider issue of food intolerance as a cause of symptoms in irritable bowel syndrome and related conditions.
