Diabetes and Blurred Vision

Don't run out and buy a new pair of glasses as soon as you notice you have blurred vision. It could just be a temporary problem that develops rapidly and is caused by high blood sugar levels.

High blood sugar causes the lens of the eye to swell, which changes your ability to see. To correct this kind of blurred vision, you need to get your blood sugar back into the target range (80 mg/dL to 140 mg/dL before meals and 100 mg/dL to 160 mg/dL before bedtime snack). It may take as long as three months after your blood sugar is well- controlled for your vision to fully get back to normal.

Diabetes and Wounds: Caring for Sores

Every 30 seconds, somewhere in the world, someone loses a lower limb as a result of diabetes. That's because diabetes and wounds are a dangerous combination. If you have diabetes, there's no such thing as a minor wound to the foot -- even a small foot sore can turn into an ulcer that, if not properly treated, can lead to amputation. The rate of amputation for people with diabetes is 10 times higher than for those who don't have the disease.  Most of these amputations could easily be prevented...

Blurred vision can also be a symptom of more serious eye problems. If your vision is blurred, contact your doctor.

The American Diabetes Association offers these eye care guidelines for people with diabetes:

  • Have an annual dilated eye exam if you are between 10 and 29 years old and have had diabetes for at least 5 years.
  • Have an annual dilated eye exam if you are 30 or older, no matter how long you've had diabetes.
  • Get a dilated eye exam if you are pregnant or planning to get pregnant.

Your level is currently

If the level is below 70 and 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.
