Type 2 Diabetes - Symptoms

Some people who have type 2 diabetes may not have any symptoms early on. Many people with the disease don't even know they have it at first. But with time, diabetes starts to cause symptoms.

High blood sugar

Common symptoms of high blood sugar include:

See more about symptoms of high blood sugar.

The higher your blood sugar rises, the more likely you are to have symptoms. If you have higher-than-normal blood sugar and don't drink enough liquids, you can get dehydrated. This can make you feel dizzy and weak, and it can lead to an emergency called a hyperosmolar state.

To learn what to do in an emergency, see When to Call a Doctor.

Low blood sugar

When your blood sugar is too low, it can also cause problems. And it can happen suddenly. Quickly treating low blood sugar can help you avoid passing out (losing consciousness). You can pass out when your blood sugar gets very low. Low blood sugar can also lead to a heart attack.

Common symptoms of low blood sugar include:

If you aren't able to tell when your blood sugar is too low (hypoglycemic unawareness), it's a good idea to test your blood sugar often. But you're not likely to get low blood sugar unless you take insulin or oral diabetes medicines.

As important as regular testing is, you also need to know what the results mean and how to use them. "Look for patterns. If your blood sugar is always high before lunch, take a look at what you had for breakfast. Maybe you need to make some changes."—Rhonda

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.
