As with low blood sugar, episodes of high blood sugar can be very dangerous for people with diabetes. They can cause long-term health problems that cannot be reversed.

In most cases, high blood sugar happens when your pancreas or injected insulin medication does not supply enough insulin to lower your blood sugar, or when your cells cannot use the insulin to lower blood sugar. Being overweight can cause the cells in your body to stop using insulin. Weight management is essential to help prevent this problem.

What Causes High Blood Sugar?

  1. Your insulin dose may be too low
  2. Your cells have stopped using the insulin over time, due to obesity
  3. You overeat during meals

How to Manage High Blood Sugar Episodes

When your blood sugar is high you may feel very hungry, thirsty, and feel the urge to urinate more than usual. If you feel this way, consider checking your blood sugar. If your blood sugar monitor shows an error because the reading is outside the higher limit of what it can report, call your doctor.

Getting advice from your doctor when this happens is important because:

  1. Uncontrolled high blood sugar can cause a condition that can lead to death within days if untreated.
  2. High blood sugar makes it take longer for wounds to heal.
  3. You may need an adjustment to the dose of insulin you take, or need to start using insulin to keep your blood sugar in range.
