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.
The cause of diabetes mellitus type 1 is unknown. Type 1 diabetes can be distinguished from type 2 by autoantibody testing. The C-peptide assay, which measures endogenous insulin production, can also be used. Administration of insulin is essential for survival.
