Has your Dad had his blood sugar levels checked?
As far as bloating and gassy, is this after he eats anything or fatty foods which may mean it's gallbladder related.
I sound like a broken record, but honestly, just ask him to go to his Doctor and get himself checked.
thank you for your generous reply ma'am .
The thing is my father doesn't eat a lot of carbs or sugar . about Candida , is there a specific blood test for it ?
could it be coeliac disease ?
You should tell him to cute out carbs and sugar from his diet as much as he can! Many people get a yeast overgrowth in their intestines called Candida, and it can cause people to have those symptoms after eating.
Another possibility is he might have a gluten intolerance. He should cut out gluten from his diet as well and see if it helps at all! Gluten intolerance can cause those symptoms
