You can help avoid blood sugar problems by following your doctor's instructions on the use of insulin or diabetes medicines, diet, and exercise.
Sometimes a woman can get diabetes during pregnancy. This is called
Children who have diabetes need their parents' help to keep their blood sugar levels in a target range and to exercise safely. Be sure that children learn the symptoms of both high and low blood sugar. Then they can tell others when they need help. There are many support groups and diabetes education centers to help parents and children understand about blood sugar, exercise, diet, and medicines.
Teens especially may have a hard time keeping their blood sugar levels in control. That's because their bodies are growing and developing. Also, they want to be with their friends and eat foods that may affect their blood sugar. Having diabetes during the teen years isn't easy. But it's an excellent age to understand the disease and its treatment. Your teen can take over some of the duties of their care.
If your blood sugar level reads too high or too low but you feel fine, you may want to recheck your sugar level or recalibrate your blood glucose meter. The problem may be with either your blood sample or the machine.
High blood sugar occurs when the sugar (glucose) level in your blood rises above your target range. Your blood sugar can rise when you eat too many calories or miss taking your medicines (insulin or pills). It can also rise when you have an infection or illness, an injury, or surgery. Even emotional stress can cause your blood sugar to rise.
High blood sugar usually happens slowly over a period of hours to days. But missing a dose of insulin can cause a quick rise in blood sugar levels. Blood sugar levels just above your target range may make you feel tired and thirsty. If your blood sugar stays higher than your target range for weeks, your body will adjust to that level. You may not have as many symptoms of high blood sugar.
Unless you don't monitor your blood sugar regularly or you don't notice the symptoms of high blood sugar, you likely will have time to treat high blood sugar so that you can prevent high blood sugar emergencies. Three things can help you prevent high blood sugar problems:
Complications of high blood sugar can cause serious problems, including coma and death. Over time, high blood sugar can damage your eyes, heart, kidneys, blood vessels, and nerves.
Low blood sugar occurs when the sugar (glucose) level in your blood drops below what your body needs. Your blood sugar can drop quickly if you don't eat enough food or you skip meals. It can also happen if you take too much medicine (insulin or pills), exercise more than usual, or take certain medicines that lower blood sugar. Do not drink alcohol if you have problems noticing the early signs of low blood sugar.
People who lose weight or develop kidney problems may not need as much insulin or other medicines as they did before they lost the weight or had kidney problems. Their blood sugar may drop too low. Be sure to check your blood sugar often when your body goes through changes.
When your blood sugar level drops below 70
You may have symptoms of low blood sugar if your blood sugar drops from a high level to a lower level. For example, if your blood sugar level has been higher than 300 mg/dL for a week or so and the level drops suddenly to 100 mg/dL, you may have symptoms of low blood sugar. This could happen even if your blood sugar is in the target range. But if you've had diabetes for many years, you may not have symptoms of low blood sugar until your blood sugar level is very low.
If your doctor thinks you have low blood sugar levels but you aren't having symptoms, your doctor may ask you to check your blood sugar more often. You may need to check your blood sugar in the middle of the night. Or you may need to do a 3-day test using a

Children usually need less than 15 grams of carbohydrate. Check with your doctor or diabetes educator for the amount that is right for your child.
Here are examples of quick-sugar foods that have 15 grams of carbohydrate:
If you have problems with severe low blood sugar, someone else may have to give you glucagon. This is a hormone that raises blood sugar levels quickly.
