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.
Latent autoimmune diabetes of adults. Latent autoimmune diabetes of adults (LADA) is a form of diabetes mellitus type 1 that occurs in adulthood, often with a slower course of onset than type 1 diabetes diagnosed in juveniles. Adults with LADA may initially be diagnosed incorrectly as having type 2 diabetes based on their age, particularly if they have risk factors for type 2 diabetes such as a strong family history or obesity.
