What is the condition in which blood glucose levels are higher than normal but not high enough for diagnosis as diabetes?
Prediabetes means you have a higher than normal blood sugar level. It’s not high enough to be considered type 2 diabetes yet, but without lifestyle changes, adults and children with prediabetes are more likely to develop type 2 diabetes.
Why must the body make sure glucose levels do not rise too high?
Having too much sugar in the blood for long periods of time can cause serious health problems if it’s not treated. Hyperglycemia can damage the vessels that supply blood to vital organs, which can increase the risk of heart disease and stroke, kidney disease, vision problems, and nerve problems.
What is the evidence of diabetes?
Type 2 diabetes is a common condition that causes high blood sugar levels. Early signs and symptoms can include frequent urination, increased thirst, feeling tired and hungry, vision problems, slow wound healing, and yeast infections.
Why must glucose levels be controlled?
It is important that the concentration of glucose in the blood is maintained at a constant level and controlled carefully. Insulin is a hormone – produced by the pancreas – that regulates glucose concentrations in the blood….Action of insulin.
| Low glucose | High glucose | |
|---|---|---|
| Effect on blood glucose level | Increases | Decreases |
What condition contributes to a greater risk of type 2 diabetes?
Inactivity. The less active you are, the greater your risk. Physical activity helps control your weight, uses up glucose as energy and makes your cells more sensitive to insulin. Family history.
What does the glucose test entail?
You will be asked to drink a liquid that contains glucose (75 g). You will have blood drawn before you drink the liquid, and again 2 more times every 60 minutes after you drink it. Each time, your blood glucose level will be checked. Allow at least 2 hours for this test.
How is glucose concentration controlled?
The concentration of glucose in the blood is determined by the balance between the rate of glucose entering and the rate of glucose leaving the circulation. These signals are delivered throughout the body by two pancreatic hormones, insulin and glucagon (Maitra, 2009).
How is glucose level maintained in the body?
The bloodstream carries glucose-a type of sugar produced from the digestion of carbohydrates and other foods-to provide energy to cells throughout the body. Unused glucose is stored mainly in the liver as glycogen. Insulin , glucagon, and other hormone levels rise and fall to keep blood sugar in a normal range.
