Hi there I understand your concern...you may be having gastroenteritis considering your history...I would suggest you to consult drink plenty of fluids,tender coconut etc to replenish water and electrolytes loss....take probiotics and antispasmodics to reduce the symptoms...take pantoprazole 40 mg before food along with domperidone...you may require clinical examination to assess dehydration and for specific diagnosis consult nearest physician they will do the needful

Dear Practo user, Probably your father is suffering from Acute gastroenteritis. Give him soft diet. Avoid oily and spicy food. Tablet Ciplox TZ twice a day, Tablet Ondem MD 4 MG three times a day, Tablet Pan 40 twice a day, Tablet Lomotil twice a day. Give him ORS or electral powder with water. Monitor urine output. Consult with your doctor if required.
