• Human Physiology
• Nutritional Science

Background:

• Lactose intolerance is a prevalent gastrointestinal issue.
• Most individuals lose the ability to digest lactose after infancy.
• Lactose is the primary carbohydrate in milk.

Purpose of the Study:

• To review the role of lactase-persistence alleles.
• To discuss the diagnosis of lactose malabsorption.
• To explore the development and management of lactose intolerance symptoms.

Main Methods:

• Literature review of lactose intolerance.
• Discussion of diagnostic methods like the lactose hydrogen breath test.
• Analysis of management strategies including dietary restriction and drug therapy.

Main Results:

• Approximately 75% of the world's population experiences lactose malabsorption.
• Symptoms vary significantly among individuals and include bloating, diarrhea, and abdominal pain.
• Effective management strategies are available.

Conclusions:

• Lactose intolerance is a common condition with diverse symptoms.
• Diagnosis is typically achieved through non-invasive breath testing.
