Lactose Intolerance: A Concise Review to Skim the Surface

Area of Science:

• Gastroenterology
• Human Genetics

Background:

• Lactose intolerance is a prevalent condition causing gastrointestinal distress.
• Current understanding and management often fall short of addressing the complexity of the condition.

Purpose of the Study:

• To provide a comprehensive review of lactose intolerance.
• To elucidate the condition's definitions, genetic underpinnings, pathogenesis, clinical manifestations, and diagnostic and management approaches.

Main Methods:

• Literature review of existing research on lactose intolerance.
• Synthesis of information regarding genetic basis, pathogenesis, clinical signs, diagnosis, and management.

Main Results:

• Lactose intolerance diagnosis extends beyond symptom observation upon dairy consumption.
• Effective management involves strategies beyond simple avoidance of milk and dairy products.

Conclusions:

• A thorough understanding of lactose intolerance requires exploring its genetic and pathogenic basis.
• Comprehensive diagnostic and management strategies are crucial for addressing this common gastrointestinal condition.
