I am really sorry to hear about your son suffering from diarrhea (I assume its not bloody stools). Any diarrhea more than 2weeks fits to be called chronic diarrhea
. Antibiotics may not help him. He needs evaluation by a good pediatrician
to find out cause and treat accordingly. Few common causes are,
Secondary Lactose intolerance
: Gut may be damaged after an episode of diarrhea resulting in prolonged loose stools after taking milk.
Cow milk protein allergy
: Blood in loose stools due to cows milk.
Celiac disease : Due to allergy to wheat. Very common in north indians.
List of causes is many and needs evaluation by a good pediatrician as said earlier.
Till then you can safely try the following,
Completely avoid milk and milk based items. Easily digestible bland diet of rice can be tried.
Zerolac (Soy based milk) can be safely tried instead of cow's milk. Zinc supplementation reduces diarrhea duration (proven). keep hydrating child with plenty of fluids, ORS to maintain good urine output (>4times/day)
Don't worry children usually recover if milk free diet is tried. Pediatrician consultation is necessary as it is becoming chronic diarrhea. Take care.
