While there are several studies that say DMII (the non-insulin-dependent diabetes mellitus) or type 2 diabetes and immune system to be correlated, there are as many studies that dennied this hypothesis but say the people who are obese and suffer from the type 2 diabetes have an altered immune system. Type 2 diabetes per se doesn’t weaken the immunity system, even if the immunity is stronger there would be instances you still contract fungal, bacterial and viral infections and not overcome those parasitic infections.

With that being said, if the diabetes goes untreated, the cells become sugar concentrated making them paradise for all microorganisms. It can be better explained like this: The person’s immune system isn’t weakened, but dysregulated, because of the presence of high concentration of sugars.

High sugar implies abundant food reserves making conducive for yeast, bacteria and other parasites to multiply. A person acquires infections very soon as the immune system becomes dwarfed and cannot eliminate them totally.

It is for the same reason the diabetics have issues with multiple yeast and bacterial and also fungal infections. These infections also presumably take time longer time to heal when compared to healing in a non-diabetic person.

So in order to keep these infections and parasites at bay and to keep immune system function well, you need to take steps to manage type 2 diabetes.

Furthermore, physicians and diabetologists believe that the hemoglobin A1C or HbA1C is correlated to immune system; and blood sugars and HbA1C are directly proportional and it gives a picture of blood glucose concentration over 2 months time period. Higher the HbA1C figures reflect higher blood glucose and likelihood for weaker immune system.

Therefore, weight loss or addressing the obesity becomes the immediate goal in those type 2 diabetics who are prone to infections and it is from an immunological perspective. This could be achieved with a combination of planned nutritious diet and exercise.

A well-balanced diet with reduced intake of saturated fats and increased omega-3 oils with generous fruits and vegetables should keep the sugars in the normal range which keeps the immune system going good. Even with diet and exercise there could be instances when insulin injections are called for. This is when the person has a non-healing wound or a ringworm infection, etc. Either insulin injection or oral hypoglycemic medications in such people help regulates the blood sugar and also triggers the wound healing in them.
