Sorry to hear about your elderly father's problem. If he has had this problem
for over a year , I hope you have already taken him to the doctors for proper
testing. Did the condition start very suddenly or gradual ? That would be vvery
important. Was he on any antibiotics for any infection before this started ?
Did he do any travel prior to the onset of diarrhea
? Has he been taking any
laxatives to regulate his bowels ? He needs to have his stool tested for infectious
bacteria.Any blood in the stool ? All these are very important. Make sure to check
all the medications he is taking. If he has lost a lot of weight , again he needs
to see the doctor who can do blood tests and your father may even need an
examination of his colon
through a scope by a specialist.
I wish him well.
