#AskTheExpert Hello Doctor, since last 5 months, my 5 years old son is having episodes of vomiting after having dinner which continues the entire night, associated with mucoid stool. Although his condition inproves after giving probiotics,zinc, but again after few days he starts vomiting and passage of mucoid stool accompanies. Stool examination has been done 3 times and it shows mucus+. What is the diagnosis and is there any relevance to initiation of vomiting after dinner? Kindly suggest diagnosis and treatment
