What Is Diabetes? Diabetes mellitus, or simply Diabetes, is a group of metabolic diseases in which a person has high blood sugar, either because the pancreas does not produce enough insulin, or because cells do not respond to the insulin that is produced.This high blood sugar produces the classical symptoms of polyuria (frequent urination), polydipsia (increased thirst) and polyphygia (increased hunger). The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies. When you have diabetes, your body either doesn’t make enough insulin or can’t use its own insulin as well as it should. This causes sugars to build up in the blood. Diabetes is the fastest growing long term disease that affects millions of people worldwide. According to the charity Diabetes UK, more than two million people in the UK have the condition and up to 750,000 more are unaware of having the condition. In the United States 25.8 million people or 8.3% of the population have diabetes. Of these, 7.0 million have undiagnosed diabetes. In 2010, about 1.9 million new cases of diabetes were diagnosed in population over 20 years. It is said that if this trend continues, 1 in 3 Americans would be diabetic by 2050. Diabetes can cause serious health complications including heart disease, blindness, kidney failure, and lower-extremity amputations.
