My grandfather is 80 years old. He often feels weak and always feel like fainting because when he eat, after a while he will shit out the food so I think because of this he becomes very weak.
His condition is very serious until sometimes he does not even have time to walk to the toilet and he will have already shitted on his pants. He have to put a potty by his side in case sometimes he cannot control he can straight away shit into the potty.
He have seen doctor before and eaten diahorea medicine before but it doesn't work. He stopped seeing doctor liao because everytime he go see doctor even if its different doctor, they will give the same medicines because medicines for diahoreas are pretty standard ones which can be bought at pharmacy without doctor prescription.
Ask him go hospital to stay he don't want. He stayed in hospital 5 years ago but whatever tests the doctors want to do on him he don't want to do.
He thinks that there is nothing wrong with him and the doctors just want to do the tests to earn money. No matter what my uncles and aunties tell him to do the tests he refuse to do it.
He have cancer more than 10 years ago and have already recovered.
Could it be the cancer have come back again?
He doesn't smoke nor drink.
What possible sickness could he have?
