All You Need to Know About the Glucose Tolerance Test

Most of the food people eat is turned directly into glucose when digested, and the body uses it as energy. The pancreas is responsible for making the hormone insulin which helps to get glucose into the cells of the body.

Diabetes is a long-term disease that occurs due to the pancreas not producing enough insulin or the body being unable to use the insulin it produces effectively.

The body is unable to process food properly to use for energy. Glucose builds up in the blood, which can lead to severe health problems.

There are two main types of diabetes. Type 1 diabetes is usually diagnosed in children and young adults and is also known as juvenile diabetes. With type 1 diabetes the body does not produce insulin. 


A glucose tolerance test can be used to screen for type 2 diabetes. Gestational diabetes can occur in
pregnant woman who have never had diabetes but have high blood glucose levels. During the
glucose test, some people may experience nausea, lightheadedness, shortness of breath, and sweating.

The Continuing Case for Point-of-Care Testing for HbA1c

There is an ongoing conflict between traditional clinical laboratories and the relative new kid on the block, point-of-care testing (POCT). Of course, the laboratory system will likely always be king. But there is absolutely a place for POCT, especially as the way in which we approach healthcare, especially diagnostics, develops beyond the usual settings.

POCT ensures the rapid provision of diagnostic information, ideally during one consultation, to enable clinical decisions to be made at the earliest opportunity. Such rapid provision of information facilitates optimization of the care process. The potential for any application of POCT can, therefore, be judged in terms of its contribution to decision making and to the process of care.

In the case of the management of diabetes patients, POCT for glycated hemoglobin (HbA1c) may offer a number of advantages—as long as the performance characteristics of the analyzers used are equivalent to those employed in the central laboratory, and can be certified as such.

Blood Test Uncovers Undiagnosed Diabetes In Hospital Patients

Hyperglycemia is a frequent finding that can be related to physiologic stress, illness and medications, including steroids and vasopressors and glycated hemoglobin (HbA1c) correlates with the average blood glucose level over the previous eight to 12 weeks.

Screening of HbA1c levels plays an important role in the diagnosis and management of diabetes mellitus in the outpatient setting but remains underused in the evaluation of hyperglycemia with undiagnosed diabetes in the inpatient setting.

Can diabetes be cured?

What Causes Diabetes?

Scientists don’t know exactly what causes diabetes. They think that type 1 diabetes is a disease in which your immune system attacks your own cells as if they were foreign invaders. This is called an autoimmune disease. In type 1 diabetes, your immune system attacks your pancreas cells and destroys their ability to make insulin. Most scientists believe that an environmental factor, such as a virus, triggers this process in your body. Your genes play a role as well. Certain people are more prone to develop diabetes.

Likewise, health experts don’t fully understand what causes type 2 diabetes. They do know that it is closely linked to obesity and it tends to run in families. Type 2 diabetes is the most common type of diabetes but you can prevent it in many cases. If you have type 2 diabetes, you may be able to reverse or control high blood sugar through diet and exercise. However, you will always have diabetes and you will always need to manage it to prevent serious health problems.

Is There a Cure for Diabetes?

Both type 1 and type 2 diabetes are chronic, lifelong conditions. Currently, there is no permanent cure for either type. However, there is hope in research for a cure and in prevention. While you can’t prevent type 1 diabetes, you may be able to prevent type 2 diabetes. Maintaining a healthy weight, eating a healthy diet, and exercising regularly are all ways you can help prevent type 2 diabetes.
