I am 30 years old diabetic and also suffer from hypothyroidism and anemia. I have a regular checks for my anemia and they are fine.

for 10 days now I have got upper abdominal pain,nausea especially after eating, my stools are very loose and yellow.I feel bloated tired and sleepy. I have also noticed that my hair is falling out!!

last year I have had an endescopy to test for coeliac disease and ulcer the test turned out to be negative.

I went to my doctor and she said that its an acid problem and she put me on emoprazole and said to me to stay away from fatty food but I still don't feel better and the pain is always there,could it be anything serious.
bear in mind I haven't taken my thyroid medication for about 2 months now.
