Although typhoid can occur simultaneously along with jaundice
but Jaundice can sometimes be confused for typhoid as the symptoms of both diseases are similar. So I feel that probably the symptoms you are talking about were prodromal symptoms of jaundice and not of typhoid.However you should confirm the presence of typhoid by a blood culture
The other important point is to stop taking oral anti diabetics and switch to injection insulin
since oral anti diabetic drugs are metabolised by liver ( except metformin
) and liver is already inflamed in jaundice.As a result the action of anti diabetic drugs is exaggerated and as a consequence blood sugar levels may fall dangerously low.
Further more jaundice is treated by giving more glucose ,you all the more need injection insulin to prevent sugar levels going very high.
Further, jaundice produces "stress" and as such in any stressful situation, the patients with diabetes
get shifted to inj. Insulin until the period of stress is over.
In nutshell it is a challenge to treat jaundice in a diabetic and so your father must be admitted in hospital and treated with intravenous glucose with injection insulin and other relevant medicines.
