Type 2 Diabetes: Living With the Disease - What Happens
Now that you have had type 2 diabetes diabetes for a while, you already know how important it is to keep your blood sugar as close to your target range as you can. Doing so can help you delay or prevent more serious health problems later.
If your diabetes gets worse, your
pancreas
may make less and less
insulin, which can make it harder for you to
control your blood sugar. When your pancreas
makes too little or no insulin, you will need to give
yourself shots of insulin.
It can be hard to find the right balance of insulin and blood sugar levels. So even if you take insulin or other diabetes medicines, there may still be times when your blood sugar is too high or too low. It's important to know the symptoms of both of these and to treat them early. For more information, see the Symptoms section of this topic.
High blood sugar emergencies
A hyperosmolar state is life-threatening and can occur when your blood sugar level is very high (400 to 500 mg/dL or higher) and you get dehydrated. You are more likely to have this problem if your blood sugar stays above 200 mg/dL.
Hyperosmolar state is treated in a hospital. You'll have frequent blood tests for glucose and electrolytes. Insulin will be given to you through a vein (intravenous, or IV) to lower your blood sugar level. You'll get fluids through the IV to get rid of the dehydration. The fluids will make you urinate, removing the excess sugar from your body.
Diabetes complications
Over time, high blood sugar that is not controlled can lead to problems with your:
-
Eyes (diabetic retinopathy
). You are also at
risk for other eye diseases, such as
cataracts and
glaucoma. - Kidneys (diabetic nephropathy).
- Nerves (diabetic neuropathy).
- Heart (leading to heart attacks).
- Blood vessels (leading to heart attack, stroke, peripheral arterial disease, and possibly amputation).
- Immune system. This puts you at risk for hard-to-treat infections and wounds that take a long time to heal, especially in your feet.
If you have had high blood sugar levels for years, you may already have one or more of these complications. For more information, see Type 2 Diabetes: Living With Complications.
Other health problems
People with diabetes often already have other health problems, such as high blood pressure and high cholesterol. Or they may get them as diabetes gets worse. These health problems can make it harder to avoid complications from diabetes.
Living with diabetes
Uncontrolled high blood sugar is the main reason why complications occur. So if you work closely with your doctor to keep your blood sugar within your target range, you may be able to avoid or prevent these problems. You may also feel better and be more in control of your life. For more information, see the Preventing Complications section of this topic.
