Hi, Welcome to HCM.
Read your problem.Since her creatinine
is high she needs to have low protein, moderate carbohydrate
and fat diet.Also should reduce water intake. Completely avoid pain killers[ NSAIDS] and drugs acting on kidney. If creatinine is increasing further she may require dialysis or even kidney transplantation
if circumstances are worsening and if you can afford. She needs to continue insulin injections for diabetes. Also watch her hemoglobin
levels which can drop.You can go to AIIMS for further management and care.
Wish her good health.Take care.
