I am a diabetic and my doctor says I should not use an electrical blanket. Why?

Well, this is not an absolute contraindication. 


Diabetics can use an electric blanket but it should be with care and the temperature should not be very high. The reason for this is that diabetics do lose their ability to sense pain. If there is excessive heat the diabetic may not be able to sense the pain and this can lead to a burn. 


Since diabetics have diminished blood supply to their legs, this small burn can quickly get out of control and easily lead to a full blown infection or an amputation. Diabetics should use caution with all electrical appliances.
