Hi.
Thanks for your query.
Noted the history about your son having loose stools for a few months, up to 6 times a day, can not feel it until it is too late. Removed lactose from the diet without any good effects. He is known to have food allergies.
This seems to be a chronic infection or inflammation of the intestines.
Since stopping lactose has not helped , get it started again, why to stop then.
I would advise you the following in such a situation:
Send the stool for tests for 3 consecutive days.
Tests of blood: CBC,
thyroid,
diabetes and liver function tests.
Ultrasonography and CT scan of the abdomen.
Colonoscopy.
If the tests are positive, get that treated properly.
If all the tests are negative, get his treated as a case of IBS, that is
irritable bowel syndrome.
Observe and avoid all the things that is giving stress and anxiety for your son and try to help him in this regards.
