Patient's Query

Hello doctor,

Last month, my mother went to the hospital for diabetics, and her reading is 200 mg before having food, and after meal reading is 300. Doctor gave her 35 points of insulin. Again she took her sugar test yesterday, and her result is 180 mg/dL (within normal levels). My mother suffering from fever right now. So my question is, Do this fever occur due to high amount of insulin even though she was within limits now? Now, what should we do? How much insulin should she take?

Hi,

Welcome to icliniq.com.

From your history, I have noted that your mother was diagnosed with uncontrolled type 2 diabetes and was on insulin since one month. Now on review, yesterday it was found that it is under control with the present dose of insulin. Coming to your concern, insulin will not cause fever, whatever dose you are taking. But uncontrolled diabetes can be a trigger for infections like urinary infections, chest infections, and even be more cautious about insulin site infections if you are not properly injecting. Please make sure you are rotating the sites of injection between the abdomen, thighs, and upper arm.

The Probable causes

The probable cause is viral fever and UTI (urinary tract infection).

Investigations to be done

Do urine routine, HBA1c (glycated hemoglobin), serum creatinine, CBC (complete blood count) with ESR (erythrocyte sedimentation rate).

Treatment plan

Continue insulin in the prescribed dose.

Preventive measures

Rotate insulin site. Do regular exercise for 30 minutes per day. Follow strict diabetic diet.

Regarding follow up

Review with the above reports. Please attach your old prescription.

Same symptoms don't mean you have the same problem. Consult a doctor now!
