Oral glucose tolerance test (OGTT)

a test to diagnose pre-diabetes and diabetes. The oral glucose tolerance test is given by a health care professional after an overnight fast. A blood sample is taken, then the patient drinks a high-glucose beverage. Blood samples are taken at intervals for 2 to 3 hours. Test results are compared with a standard and show how the body uses glucose over time.

Oral hypoglycemic agents (hy-po-gly-SEE-mik)

medicines taken by mouth by people with Type 2 diabetes to keep blood glucose levels as close to normal as possible. Classes of oral hypoglycemic agents are alpha-glucosidase inhibitors, biguanides, D-phenylalanine derivatives, meglitinides, sulfonylureas, and thiazolidinediones.
