Unexpected weight loss, exhaustion, increased thirst, frequent urination – all these symptoms indicate diabetes mellitus: a condition that occurs when the body does not process glucose properly.
During digestion, the food you eat is converted into a sugar called glucose, which your body uses for energy. To move glucose from the blood stream into your cells your body needs insulin, a hormone produced by the pancreas. In diabetics, the pancreas is either unable to produce enough insulin or the body is unable to react appropriately to the insulin that is being produced. In both cases, because the glucose does not get converted into energy, it accumulates in the blood and causes a rise in blood sugar levels.
