Confirming a diagnosis of type 2 diabetes is typically done through a combination of blood tests and a physical exam.
Firstly, the doctor will likely conduct a fasting plasma glucose test. This test measures the amount of glucose in the blood after a person has fasted for at least eight hours. If the result is higher than normal, the doctor may then recommend a glucose tolerance test. This test measures the body’s ability to process glucose after drinking a glucose-containing beverage. If the results of both tests are higher than normal, then it is likely that the patient has type 2 diabetes.
The doctor may also conduct other tests to confirm the diagnosis, such as an A1C test. This test measures the average amount of glucose in the blood over the past two to three months. If the results of this test are higher than normal, it is likely that the patient has type 2 diabetes.
In addition to blood tests, the doctor may conduct a physical exam to check for signs of type 2 diabetes. These signs could include weight loss, excessive thirst, and frequent urination. The doctor may also check for signs of diabetes-related complications, such as numbness or tingling in the extremities.
Once the diagnosis is confirmed, the doctor will likely recommend lifestyle changes to help manage the condition. These changes could include regular exercise, healthy eating, and weight loss. The doctor may also prescribe medications to help control blood sugar levels.
In summary, type 2 diabetes is typically confirmed through a combination of blood tests and a physical exam. The doctor may also recommend lifestyle changes and medications to help manage the condition.
