What exactly is insulin resistance? Why can't your body absorb sugar efficiently?
Insulin resistance has become an important health issue in today's society. Many people are not familiar with this pathological condition, but it invisibly affects their health. Insulin resistance refers to the body's abnormal response to insulin, which makes it impossible for cells to effectively use insulin to absorb glucose in the blood, leading to a series of health problems, including diabetes and metabolic syndrome.
Causes of Insulin ResistanceInsulin is a hormone secreted by the pancreas. Its main function is to help transport glucose in the blood into cells and lower blood sugar levels.
The causes of insulin resistance are varied and complex. The main causes include genetic factors, lifestyle and environmental influences. Here are some common risk factors:
- Obesity or Russell's disease.
- A sedentary lifestyle.
- Family history of diabetes.
- Some health conditions, such as polycystic ovary syndrome.
The impact of lifestyle and diet
Dietary habits play an important role in insulin resistance. Studies have found that high-sugar foods and foods with a high glycemic index increase the risk of insulin resistance. In addition, excessive intake of high-fat and high-sugar foods is also considered to be one of the main factors causing metabolic syndrome.
Dietary adjustments can change the ratio of polyunsaturated fatty acids to saturated fatty acids in cell membranes, thereby affecting insulin sensitivity.
Diagnosis of insulin resistance
Diagnosing insulin resistance usually involves checking fasting insulin levels and doing a glucose tolerance test. Fasting insulin levels above 29 micro IU/mL may indicate insulin resistance. The glucose tolerance test measures blood sugar levels within two hours after eating, with the normal range being less than 7.8 mmol/L.
Prevention and Management
Maintaining a healthy weight and exercising regularly are effective ways to prevent developing insulin resistance. Many studies have shown that combining exercise with a healthy diet can significantly reduce the risk of diabetes.
Weight loss and increased physical activity can improve or reverse insulin resistance.
When the body's cells cannot absorb glucose effectively, the pancreas releases more insulin to try to compensate, which results in hyperinsulinemia. Over time, this condition can further lead to abnormalities in fasting and postprandial blood sugar levels, and may eventually lead to the development of type 2 diabetes.
ConclusionInsulin resistance is an increasingly common health problem, but it can be changed through lifestyle changes. Diet, exercise and a healthy lifestyle are important measures. Facing changes in the internal environment, how should we better protect our health so as not to become victims of insulin resistance?
