There are different types of diabetes. Type 1 or juvenile diabetes occurs in children and adolescents. The pancreas stops producing the insulin needed to move glucose (sugar) from the blood into cells to be used as energy. Those with type 1 diabetes must take insulin shots for the rest of there lives. The good news is that the insulin shots can usually control blood sugar nicely, as long as the dose is correct. To much insulin may cause blood sugar to drop to a dangerously low level, which could be deadly. Too much insulin and thus too low of blood sugar is the most immediate danger to the type 1 diabetic.
Type 2 diabetes occurs in adults when either the pancreas stops making sufficient insulin or the body becomes resistant to insulin rendering it ineffective. Those with type 2 diabetes usually do not have the same risk of low blood sugar from insulin shots as type one diabetics because of insulin resistance. Most often they will have difficulty bringing the blood sugar down to normal even with insulin. However, a large enough dose of insulin will put anyone in danger. Type 2 Diabetics usually need a combination of diet, exercise and drugs to reduce blood sugar to normal levels. Also, stress can cause high blood sugar so a low stress lifestyle can be important as well.
