The short explanation
This pattern does fit lactose intolerance quite well. Lactose is the natural sugar in milk, and digesting it needs an enzyme called lactase. Many adults, especially in South Asia, produce less lactase as they grow older. When undigested lactose reaches the large intestine, bacteria ferment it, causing gas, bloating, cramps and loose stools. Curd is often better tolerated because the bacteria in it have already broken down some of the lactose. Paneer and aged cheeses also contain less lactose than milk. Many people manage well by reducing the amount of milk at one time, taking it with food, or choosing curd and buttermilk instead.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Lactose intolerance is different from a milk allergy, which can cause rashes, swelling or breathing problems and needs medical advice.
- If you cut down on dairy, make sure you get calcium from other foods such as ragi, sesame, green leafy vegetables and pulses.
- Similar symptoms can come from IBS or gut infections, so if symptoms continue after cutting milk, see a doctor.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot confirm lactose intolerance. A doctor may suggest a trial of avoiding milk or a specific test.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Do my symptoms fit lactose intolerance?
- Do I need a test to confirm it?
- How can I make sure I get enough calcium?
- Could something else be causing these symptoms?
When to seek help
