Hello, Thanks for the query. I have seen the details given. Following are a few suggestions since there are no details given about blood glucose control, drugs being taken, duration of diabetes, if there are any other complications like neuropathy and retinal problem present or not, no info on lipids, actual body weight & height and dietary pattern. 1) Please see that your blood glucose is very well controlled with fasting glucose 3) Avoid sweets, junk foods, pastries, colas, bakery items, too much of cheese, 4) Refrain from alcohol and smoking, 5)Increase the intake of green leafy vegetables and salads and permitted fruits. 6) You may have to look at your current treatment and if needed change it completely. 7) Also get a thyroid assay done to see if there is any problem with that gland too. Because just having diabetes even if it is a bit uncontrolled will not sap your energy totally. It is absolutely essential for you to take proper medical guidance from a good diabetologist in your locality. Because at 40 years you are too young to have these kind of problems. Please force your self to do some physical exercise daily. Begin with 10 to 15 minutes and then increase the duration and intensity. I hope these suggestions do help. Thanks.
