Normally, the body's immune system fights off foreign invaders like viruses or bacteria. But for unknown reasons, in people with type 1 diabetes, the immune system attacks various cells in the body. This results in a complete deficiency of the insulin hormone.
For most people, a bad shoe day means a blistered heel or painful arch that goes away quickly. But for people with diabetes, poor footwear can trigger serious problems, such as foot ulcers, infections, and even amputation.
Foot problems aren't inevitable, though. Ralph Guanci learned the hard way to pick his shoes with care and to stick with wearing them because they're good medicine for his feet.
Guanci, 57, a businessman in Carlisle, Massachusetts, was diagnosed with type 2 diabetes 25 years...
Normally, the hormone insulin is secreted by the pancreas in low amounts. When you eat a meal, sugar (glucose) from food stimulates the pancreas to release insulin. The amount that is released is proportional to the amount that is required by the size of that particular meal.
Insulin's main role is to help move certain nutrients -- especially sugar -- into the cells of the body's tissues. Cells use sugars and other nutrients from meals as a source of energy to function.
The amount of sugar in the blood decreases once it enters the cells. Normally, that signals the beta cells in the pancreas to lower the amount of insulin secreted so that you don't develop low blood sugar levels (hypoglycemia). But the destruction of the beta cells that occurs with type 1 diabetes throws the entire process into disarray.
In people with type 1 diabetes, sugar isn't moved into the cells, because insulin is not available. When sugar builds up in the blood instead of going into cells, the body's cells starve for nutrients and other systems in the body must provide energy for many important bodily functions. As a result, high blood sugar develops and can cause:
Dehydration. The buildup of sugar in the blood can cause an increase in urination (to try to clear the sugar from the body). When the kidneys lose the glucose through the urine, a large amount of water is also lost, causing dehydration.
Weight loss. The loss of sugar in the urine means a loss of calories; therefore, many people with high sugars lose weight. (Dehydration also contributes to weight loss.)
Diabetic ketoacidosis (DKA). Without insulin and because the cells are starved of energy, the body breaks down fat cells. Products of this fat breakdown include acidic chemicals called ketones that can be used for energy. Levels of these ketones begin to build up in the blood, causing an increased acidity. The liver continues to release the sugar it stores to help out. Because the body cannot use these sugars without insulin, more sugar piles into the bloodstream. The combination of high excess sugars, dehydration, and acid buildup is known as "ketoacidosis" and can be life-threatening if not treated immediately.

Your level is currently
If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.
People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.
Congratulations on taking steps to manage your health.
However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.
Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.
Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.
One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
