It's reassuring that your father's blood
sugar is now well controlled (102 mg/dL before meals and 140 mg/dL after meals). After major surgeries like bypass surgery, blood sugar levels often increase temporarily due to the stress of surgery, so doctors may adjust
diabetes medications during recovery.
Since his sugars are currently within the target range, I would not advise switching back to his previous medication without consulting his treating doctor. Let him continue the current treatment for now. During his follow-up visit, the doctor can review his blood sugar log,
HbA1c,
kidney function, and overall recovery to decide whether he can return to his earlier medication.
