Diabetes is often referred to as a silent killer.

Check your glucose level!
The more severe form of diabetes is Type 1, or insulin-dependent diabetes. It's sometimes called "juvenile" diabetes because Type 1 diabetes usually develops in children and teenagers, though it can develop at any age.
With Type 1 diabetes, the body's immune system attacks part of its own pancreas. Scientists are not sure why, but the immune system mistakenly sees the insulin-producing cells in the pancreas as foreign, and destroys them. This attack is known as autoimmune disease. These cells - called "islets" (pronounced EYE-lets) - are the ones that sense glucose in the blood and, in response, produce the necessary amount of insulin to normalise blood sugars. Insulin serves as a "key" to open your cells to allow the glucose to enter - and to allow you to use the glucose for energy.
Without insulin, there is no "key". So, the sugar stays - and builds up - in the blood. The result: the body's cells starve from the lack of glucose. And, if left untreated, the high level of blood sugar can damage eyes, kidneys, nerves, and the heart, and can also lead to coma and death.
So, a person with Type 1 diabetes treats the disease by taking insulin injections. This outside source of insulin now serves as the "key" - bringing glucose to the body's cells.
The challenge with this treatment is that it's often not possible to know precisely how much insulin to take. The amount is based on many factors, including:These factors fluctuate greatly throughout every day. So, deciding what dose of insulin to take is a complicated balancing act. If you take too much, then your body burns too much glucose - and your blood sugar can drop to a dangerously low level. This is a condition called hypoglycemia, which, if untreated, can be potentially life-threatening. If you take too little insulin, your body can again be starved of the energy it needs, and your blood sugar can rise to a dangerously high level - a condition called hyperglycemia. This also increases the chance of long-term complications.
