It can be difficult to tell the difference between strep throat symptoms and symptoms of a viral infection, like mononucleosis (mono), which is also common in teens. Just like strep throat symptoms, with mono you will experience a sore throat, fever, swollen lymph nodes, rash and body aches.
Type 1 Diabetes. Type 1 diabetes is an autoimmune disease. An autoimmune disease results when the body's system for fighting infection (the immune system) turns against a part of the body. In diabetes, the immune system attacks the insulin-producing beta cells in the pancreas and destroys them. The pancreas then produces little or no insulin.
There are two primary types of diabetes. Type 1 diabetes is an autoimmune disease that requires daily use of insulin. Symptoms of Type 1 may include increased thirst and urination, constant hunger, weight loss, blurred vision, and extreme fatigue. Often diagnosed in childhood and in young adults, this type of diabetes accounts for about 5 to 10% of diagnosed cases in the United States.
