HI, thanks for using healthcare magic
Diarrhea is most commonly due to bacterial or viral infection with viral infection being more common of the two.
It can be associated with the
fatigue and fever that you are experiencing.
The
chills that you are having are related to fever.
Diabetes can affect the immune system and affect your response or recovery if your blood sugars are not controlled.
Treatment of diarrhea would include: (1) monitoring your blood sugars , may need to alter your medications
(2)holding off solid food till there is a 4 hour window with no symptoms
(then start with the dry solid food like you were doing eg toast). Using solids when the intestine is not ready would delay healing and worsen symptoms
(3)fluids to replace what is lost. Normally oral rehydration solutions and sport drinks are recommended
(4)probiotics- help to shorten the course of the illness
(5)meds such as
lomotil or pepto bismol
I hope this helps, feel free to ask any other questions
