Although they don't develop ketoacidosis, type 2 diabetics can experience a different kind of catastrophe, known as hyperosmolar syndrome. High blood sugar causes increased urination and loss of fluid. If the person is taking diuretics, the condition can get worse. This condition is not an uncommon occurrence for elderly diabetics living alone. They may get sick, lose control of their blood sugar, and forget to drink enough water.
Severe dehydration leads to low blood pressure, loss of consciousness, and eventually deep coma.
These people are treated with intravenous fluids and insulin. This complication does not naturally develop with diabetes, but is caused by the power of the treatments if taken in excessive doses. Severe hypoglycemia can result from taking more insulin or oral diabetes medication than you need. It occurs most commonly in people who are on insulin. Exercise and certain illnesses may also contribute to its occurrence.
