Factors that may increase your chances of hypoglycemia:
Taking medicines that lower blood sugar levels
Drinking too much alcohol
Fasting (worse when it happens with intense exercise)
Symptoms may come on slowly or quickly. Hypoglycemia may cause:
Tingling feeling around the mouth
As hypoglycemia worsens, it may cause:
A change in behavior or confusion
Poor control of movements
Loss of consciousness
Early symptoms may start to fade if you have a lot of events. The symptoms may stop all together. This means you will not have early warning. It will increase the chance of a having a severe drop in glucose. Get to know your early signs. Quick care can stop future problems.
You will be asked about your symptoms and health past. An exam will be done.
Your doctor will try to track your low blood glucose. Your blood glucose levels will need to be measured while you are having symptoms. This is a common step with diabetes care.
If you do not have diabetes, other tests may need to be done. This may include checking your blood levels after fasting.
Treatment will bring blood glucose levels back to normal. This will make a quick fix. Other steps may be needed to keep it from occurring again.
In people who can eat or drink, symptoms of low blood sugar can be relieved quickly by:
Eating sugar that is easily passed into blood, such as:
Sugared soft drink
Table sugar in water
Honey or corn syrup
Taking glucose tablets
Once blood glucose has risen to normal levels, a snack or meal can help to keep levels stable.
If someone is not conscious, care may need to be delivered such as:
Glucagon—a hormone that raises blood sugar levels
To help reduce your chance of hypoglycemia:
For people with diabetes:
Check your medicine. Take it as prescribed.
Follow the food and exercise plans given by your doctor.
Check your blood glucose often.
