Impaired Fasting Glucose (IFG) is a type of prediabetes, where a person's blood sugar levels during periods of fasting are consistently higher than normal, but not high enough to be classified as diabetes.
Definition[edit]
The World Health Organization (WHO) and the American Diabetes Association (ADA) have slightly different views on the definition of IFG. According to the WHO, IFG is a fasting glucose level of 6.1 mmol/L (110 mg/dL) to 6.9 mmol/L (125 mg/dL). The ADA defines IFG as a fasting glucose level of 5.6 mmol/L (100 mg/dL) to 6.9 mmol/L (125 mg/dL).
Causes[edit]
IFG is often caused by insulin resistance, a condition in which the body's cells do not respond properly to insulin, leading to higher levels of glucose in the blood. Other factors that may contribute to IFG include obesity, a lack of physical activity, and a diet high in sugars and fats.
Symptoms[edit]
People with IFG often do not have any symptoms. However, they are at a higher risk of developing type 2 diabetes and cardiovascular disease.
Diagnosis[edit]
IFG is diagnosed through a Fasting plasma glucose test, which measures the level of glucose in a person's blood after an overnight fast. If the test shows a fasting blood glucose level between 100 and 125 mg/dL, it may indicate IFG.
Treatment[edit]
Treatment for IFG focuses on lifestyle changes such as increasing physical activity, eating a healthy diet, and losing weight if necessary. Medications may also be prescribed in some cases.
Prevention[edit]
Prevention of IFG involves maintaining a healthy lifestyle, including regular physical activity, a balanced diet, and maintaining a healthy weight.
