If someone is suffering from uncontrolled diabetes then it is likely for them to develop weak immune system. Diabetics are immunocompromised because hyperglycemia is known to suppress immune response towards intruders and pathogens. This makes a diabetic prone to developing infections. Moreover, diabetics experience complications like nerve damage and reduced blood supply to the extremities. This also contributes in suppressing the immune system. Since diabetics are immunocompromised therefore the mortality rate is higher especially when they are hospitalized. Some common infections include foot infections, UTI, yeast infections and surgical site infections. Diabetic neuropathy, hyperglycemia and hypertension in diabetes weaken the immune system of diabetic.
