What lactose intolerance is
Lactose is the natural sugar in milk. To digest it, the small intestine makes an enzyme called lactase. Many adults — a large proportion in South Asia — make less lactase after childhood. Undigested lactose then reaches the large bowel, where bacteria ferment it, causing gas, bloating, cramps and loose stools, usually within a few hours of having milk.
Intolerance or allergy?
- Lactose intolerance is a digestive problem — uncomfortable but not dangerous.
- Milk allergy is an immune reaction to milk protein. It can cause hives, swelling, vomiting, wheezing or, rarely, anaphylaxis — and needs medical assessment.
How it is usually identified
Often a two-week trial of reducing milk, followed by reintroducing it, makes the pattern clear. A doctor may suggest a breath test or other tests, and will consider other causes if symptoms do not fit — such as IBS, coeliac disease or infections.
Eating well with lactose intolerance
- Many people manage small amounts of milk, especially with meals.
- Curd (dahi), buttermilk and aged cheese are often better tolerated than plain milk.
- Lactose-free milk is available in many cities.
- Keep calcium up from other sources — ragi, sesame, green leafy vegetables, paneer, almonds — and ask your doctor about vitamin D.
- Avoid cutting out dairy completely for children without advice.
When to see a doctor
- Blood in the stool, weight loss, or symptoms that wake you at night
- Symptoms starting after age 45, or a family history of coeliac or inflammatory bowel disease
- Hives, lip swelling, wheezing or vomiting after milk — this may be allergy, not intolerance
- A child with poor weight gain or ongoing diarrhoea
How homoeopathic care fits
Some people with lactose intolerance also have wider digestive complaints — bloating, irregular bowels, acidity — and seek homoeopathic care for the overall picture. The consultation covers diet, bowel pattern, stress and general health, alongside sensible dietary adjustment. Treatment duration and response are highly individual and are reviewed honestly at each follow-up.
