Huntington Woods Type 2 Diabetes: Type 2 Diabetes is a chronic condition that affects the way the body processes blood sugar (glucose). In type 2 diabetes, the body either doesn’t produce enough insulin or it resists insulin. Symptoms typically include increased thirst, frequent urination, hunger, fatigue, and blurred vision. Fatigue or stress causes your cortisol levels to be elevated, and this anti-inflammatory effect becomes too strong. This effectively stops your immune system from working as it should, and this weakened state can last for whatever is causing the stress.
