My wife is 60 yrs old and suffering from type-2 diabetic for last 6yrs. Now she had uti problem along with increased sugar. When uti was cured she had blood sugar of 370 (PP) in spite of taking oral medicines. Then Doctor had prescribed to take insulin dosages 2 times per day along with previous medicines. Within 7 days sugar level has come down to 140 (pre-meal. Now my questions are: 1. Is insulin to be taken permanently? We want to replace insulin by oral medicines. Is it possible? She is mentally and physically very very weak and disturbed. Is it due to sugar problem or may be for taking heavy antibiotics for uti treatment? Is it required to treat it separately by doctor other than diabetic specialist? if yes then which specialist department to be visited? Please help me with your valuable advises.
