Diabetes refers to a group of metabolic disease characterized by high blood sugar level. Diabetes occurs due to inadequate secretion of insulin inside the pancreas. Some of the common symptoms for diabetes are frequent urination, excessive thirst, increased hunger, weight loss and tiredness. Type 1, type 2 and gestational diabetes are three types of diabetes. Type 1 diabetes is an autoimmune disease occurred due to high blood glucose level whereas, type 2 diabetes is a lifelong chronic diseases caused due to excess secretion of insulin inside the body. In type 1 diabetes, the immune system is activated against self-insulin producing cells. This results into low production of insulin and also disrupts blood glucose homeostasis. In type 1 diabetes, exposure to viral infection such as mumps and coxsackie viruses results into pancreas damage which results into low insulin secretion. Type 1 diabetes is highly prevalent in young people and children whereas type 2 diabetes is common type of diabetes. Some of the common symptoms for type 2 diabetes are overweight, high blood pressure and high triglycerides. Diabetes is treated with the help of insulin delivery devices and drugs. Diabetes diagnostic devices includes analog blood meter, test strips, lancets and lancing devices whereas, insulin delivery devices includes insulin syringe, insulin pump, insulin pen and insulin jet injectors. Severe problems such as blindness, kidney failure, coronary heart disease and strokes may result due to lack of proper treatment.
