Hi, Welcome to HCM You have diabetes which is uncontrolled and also have infection in the form of UTI. It is not known if you have type I or Type II with failure of anti diabetic drugs. Insulin is very good and logical treatment of diabetes and Basal insulin starting dose is .2U/Kg body weight at the same time of day but needs to be monitored by frequent blood sugar measurement and diet advise as carbohydrate content of diet changes requirement and dose needs to be increased according to sugar level. You should consult Physician/Endocrinologist and decide about anti diabetic treatment as some other medication may be required and additional different insulin may be required. UTI must be treated with proper antibiotics and if required urine culture and sensitivity must be performed. You should take care of diet and exercise and take plenty of water. It is good that you have started insulin, soon you will control sugar level an start feeling well. If you are over weight may be metformin may be added by your doctor. Take care Good Luck
