Hence, it’s of utmost importance to know actually what the problem is and to get it diagnosed by a professional.

Let’s just dive a little more into the topic, So, what is Lactose intolerance?

The inability to fully digest sugar (lactose) in dairy products and hence causing symptoms, particularly after intake of such products.


  1. Congenital or primary:
    Due to mutation of lactose gene in the chromosome number 2, very rare type.
  2. Acquired or secondary:
    -More common type and causes include Autoimmune, Gastroenteritis, Post infectious following diarrhoea, due to infection, adverse effects of drug, radiation.

Signs and symptoms:

  1. Reducing substances positive in stool.

  3. Decrease lactase activity in small intestine biopsy.
  4. Breath test:
    -Gas used is Hydrogen(H2)
    -8hr Fasting prior to this test.

Lactose is absorbed in the small intestine,
However, for people with lactose intolerance, it passes straight into the colon and is fermented by the gut bacteria which produces hydrogen which gets expelled out of the body via different routes.
The patient is asked to breathe in a piece of equipment and the baseline hydrogen level is recorded.
Then a Solution of Glass with the same amount of lactose as 0.5 litres of milk is given to the patient.
The patient has to wait for 2 hours.
The patient again reason that equipment,
Levels of hydrogen are recorded.

If hydrogen level goes 20 points above the baseline.


  1. Avoid milk, skimmed milk and Milk products like ice cream,
    Include small servings of dairy products in your regular meals

These patients must maintain
their daily calcium requirement since
Calcium builds our bone density and it is Reserved in our body since after the mid-’20s the density starts decreasing.
Hence it is important to build the highest bone density, by having an adequate supply of calcium in our diet.
