Insulin Resistance (HOMA2)

Price: 35 د.ا

Insulin resistance is a condition in which the body’s cells lose their effective response to insulin, causing the pancreas to produce more insulin in order to maintain blood sugar levels. The HOMA2 (Homeostasis Model Assessment 2) test is an effective method for evaluating insulin resistance and provides insights into metabolic health.

Normal Range for Insulin Resistance (HOMA2):

• Females: A HOMA2 index less than 1.0 is considered within the normal range.
• Males: For men, a HOMA2 index less than 1.0 is also considered normal.
• Children: Normal values vary with age, but generally, a HOMA2 index less than 2.5 is considered healthy for children.

Note: These values may vary depending on age, health status, and laboratory standards. Always consult a physician for accurate interpretation.

Function of Insulin in the Body:

Insulin resistance occurs when the body’s cells become less responsive to the insulin hormone that regulates blood sugar levels. As a result, the pancreas secretes more insulin to maintain glucose stability. The HOMA2 test measures insulin resistance by analyzing fasting glucose and insulin levels, providing a numerical value that reflects how efficiently the body processes glucose and insulin.

Diseases Revealed by the HOMA2 Test:

The test helps detect insulin resistance, which is an early indicator of several metabolic conditions, including:

• Type 2 Diabetes: Insulin resistance is a major factor in the development of type 2 diabetes.
• Metabolic Syndrome: A cluster of conditions that increase the risk of heart disease and stroke.
• Polycystic Ovary Syndrome (PCOS): Many women with PCOS experience insulin resistance.
• Non-Alcoholic Fatty Liver Disease (NAFLD): Often associated with insulin resistance.

Symptoms of Insulin Resistance:

Insulin resistance develops gradually, and its symptoms may be subtle. They include:

• Fatigue: Reduced energy and a feeling of sluggishness, particularly after meals.
• Increased Appetite: Constant hunger, especially cravings for sugars or carbohydrates.
• Weight Gain: Difficulty losing weight, especially around the abdomen.
• Skin Changes: Dark patches on the skin (acanthosis nigricans) typically appear around the neck, armpits, and thighs.
• High Blood Pressure: Elevated blood pressure may also be a sign of insulin resistance.

Symptoms of Deficiency and Excess in Insulin:

• Insulin Deficiency (Extreme Resistance Leading to Diabetes):
  When cells become highly resistant, blood sugar levels rise, which may lead to type 2 diabetes. Symptoms include frequent urination, intense thirst, and fatigue.
• Excess Insulin (Hyperinsulinemia due to Resistance):
  High insulin levels in the blood can cause hypoglycemia (low blood sugar), leading to dizziness, confusion, trembling, and excessive sweating.

Methods for Diagnosing Insulin Resistance:

Diagnosis is based on a combination of clinical symptoms and laboratory tests, such as:

• HOMA2 Test: Uses fasting glucose and insulin measurements to estimate insulin resistance.
• Fasting Blood Sugar Test: Measures blood glucose after an overnight fast.
• Oral Glucose Tolerance Test (OGTT): Evaluates the body’s ability to handle glucose over time.
• Hemoglobin A1c Test: Provides an average blood sugar level over 2-3 months and is used in diagnosing diabetes.

The diagnosis is confirmed based on multiple test results and a comprehensive evaluation of the patient’s overall health.

Frequently Asked Questions:

1. What is the HOMA2 test?
   It is a test that calculates fasting glucose and insulin levels to assess insulin resistance and overall metabolic health.

2. How is insulin resistance treated?
   Treatment involves a healthy diet rich in fiber and low in refined sugars, regular physical activity, weight loss (if needed), and, in some cases, medications such as metformin under medical supervision.

3. Can insulin resistance be prevented?
   Yes, by maintaining a healthy lifestyle with balanced nutrition, regular exercise, and weight management.

4. Does insulin resistance mean I have diabetes?
   Not necessarily, but it increases the risk of developing type 2 diabetes if left unmanaged.

5. Can insulin resistance be reversed?
   Yes, improving insulin sensitivity is possible through lifestyle changes such as weight loss and increased physical activity.

Medical Laboratory Professionals’ primary duty is the patients, placing their welfare above their own needs and desires thus ensuring that each patient receives the best service and the highest quality of care according to current standards of practice. High quality laboratory services are safe, effective, efficient, timely, equitable, and patient-centered. Medical Laboratory Professionals work with all patients and samples without regard to disease state, ethnicity, race, religion, or sexual orientation. Medical Laboratory Professionals prevent and avoid conflicts of interest that undermine the best interests of patients. Learn More
