How do I treat high blood sugar?
High blood sugar is a blood sugar that is higher than your target range. It is normal to have a high blood sugar once in a while.
Call your diabetes nurses if you have:
- High blood sugar a lot of the time
- High blood sugar about the same time each day
The nurses can help figure out the reason for the high blood sugar and suggest changes in medicine, exercise, or eating to help the high blood sugars come down.
High blood sugar over a long period of time, such as months or years, causes damage to body organs. This damage is not usually seen for 10 years or longer.
High blood sugars, over time, lead to:
- Kidney damage and kidney failure
- Blood vessel damage that can cause heart attacks and strokes
- Eye problems that can lead to poor vision or blindness
- Nerve damage that can cause pain like pins and needles in the feet and legs
- Skin infections and sores that do not heal and could lead to surgery to remove a toe, foot, or leg
- Sexual problems, such as not being able to get an erection
Keeping your blood sugar normal lowers your risk for these long-term problems.
