No its not contagious, however it can be hereditary.
Most people with diabetes type II are taking insulin in prescribed doses. If they take their insulin but then don't eat very many carbohydrates then their blood sugar falls and they get hypoglycemia. This is the most common reason for hypoglycemia in diabetics.
People with type II diabetes may also have a problem with hypersecretion of insulin. Because they are insulin resistant, their blood sugar skyrockets after a meal. This signals the pancreas to release more insulin, and if it releases too much too fast their blood sugar goes down and they get hypoglycemic symptoms.
The term diabetes (is Greek) was coined by Aretaeus of Cappadocia (he practiced medicine about 100 AD). It is derived from the Greek word, diabaínein that literally means "passing through," or "siphon", a reference to one of diabetes' major symptoms-excessive urine production. In 1675, Thomas Willis added the word mellitus, from the Latin meaning "honey", a reference to the sweet taste of the urine. This sweet taste had been noticed in urine by the ancient Greeks, Chinese, Egyptians, and Indians. In 1776, Matthew Dobson confirmed that the sweet taste was because of an excess of a kind of sugar in the urine and blood of people with diabetes.

It is an important source of energy, usually found in our muscles. Produces phosphate and creatine and releases energy used to make adenosine triphosphate (ATP). When split, ATP provides energy for muscle cell function.
