Follow-up glucose tolerance test

Follow-up test involves fasting overnight and measuring your fasting blood sugar level. You need to drink a higher concentration of glucose solution.

After that your blood sugar levels are checked every hour for three consecutive hours. If two of the readings are higher than the normal range than you have gestational diabetes.

Diabetes testing in children

In children, usually there are no symptoms seen when they are diagnosed with type 2 diabetes. This is mostly found out from the urine sample or blood sample which is given for testing for some other health problem.

If you find out that your child is having higher blood glucose levels than the normal range then you should consult a doctor for this matter.

If your child’s blood sugar level does not cross the prediabetes range then the doctor will make some alterations in the diet plan and exercise routine in order to help your child to avoid diabetes. You should be careful if your child is overweight because that is one of the major causes of diabetes.
