Hi welcome to HCMForum. first of all your father had bleeding in the stomach resulted in vomiting
followed by brown curdy blood clots
the renant blood can cause loose motions. The other reason is infection causing vomiting gastric bleeding followed by motions.
can some times cause such changes. what ever the reason must be treated by antibiotic ppi probiotics etc for few days
to stabilise the gut. in the last 2 instances we dont get any thing in gastro scopy. For bloating
ask him to stop all the drugs. if no
improve ment he has to use gastrokinetic drugs only under the supervision of a gastro enterologist. besides ask him to use more curd
with food. avoid spices chillies
