Hi ! If you are eating frequently from outside, then you should avoid it as infection can come in from food made unhygienic-ally outside.
Go for a stool test
to exclude ova and cyst. If positive, then take appropriate medications as per the advice of your family doctor.
To know if it is celiac disease
, you have to modify your food (gluten free
)as per the advice of a dietician, and if that improves, then possibly it was a celiac disease. But it may take patient waiting to confirm or exclude it, and confirmation may be by way of an endoscopic biopsy
from mucosa of small intestine
. Wishing you an early recovery.
