Overview
Lactose intolerance means your body can't fully digest lactose — the sugar found in milk and dairy products. This happens because you don't produce enough lactase, the enzyme that breaks down lactose. It's very common (especially in the Middle East) and is not the same as a milk allergy. It's not dangerous, but can be uncomfortable.
Symptoms
Bloating and gas after dairy
Diarrhea or loose stools
Abdominal cramps
Nausea after consuming milk products
Symptoms appear 30 min to 2 hours after dairy
Common Causes
Genetic — lactase production decreases with age (primary)
Damage to small intestine from illness (secondary)
Very common in Middle Eastern, Asian, and African populations
Not related to milk allergy (which involves the immune system)
Self-Care Tips
Try lactose-free milk and dairy products
Take lactase enzyme supplements before eating dairy
Yogurt and aged cheeses are usually better tolerated
Read food labels for hidden lactose
Ensure adequate calcium from non-dairy sources
Start with small amounts of dairy to find your tolerance level
When to See a Doctor
See a doctor if you're unsure whether it's lactose intolerance or a milk allergy, or if symptoms persist despite avoiding dairy (may indicate another condition).
