Diabetes mellitus is a class of metabolic conditions characterized by high blood sugar. In Type 1 diabetes, the pancreas no longer produces insulin, which means that sugar has no means to enter cells. In Type 2 diabetes, insulin resistance means that even though insulin is being produced, cells do not respond to it. Weight and diet play a part in developing diabetes Type 2, but genetics is also a factor. I often fall into dangerous lows (a side effect of taking too much insulin, which sends blood sugar plummeting).
