The doctor will ask about your symptoms and medical history. A physical exam will be done.
The National Cholesterol Education Program offers these criteria for diagnosing metabolic syndrome. With these criteria, you have metabolic syndrome if you have 3 of the 5 following conditions:
Central obesity occurs when extra fat tissue is concentrated in the waist area. This has been found to have greater metabolic consequences than when fat is concentrated in the hips and thighs. Central obesity may be defined as:
- In men—waist measurement greater than or equal to 40 inches (102 cm)
- In women—waist measurement greater than or equal to 35 inches (89 cm)
There is some variation in this guideline with ethnicity in relation to overall size.
When your body cannot appropriately control the levels of sugar in the blood, impaired fasting glucose occurs. This is defined as a fasting glucose level greater than or equal to 100 mg/dL (5.6 mmol/L). People previously diagnosed with type 2 diabetes also meet this criterium.
Elevated blood pressure is defined as a blood pressure greater than or equal to 130/85 mm Hg.
Triglycerides are a kind of fat found in your blood. This is defined as fasting blood triglycerides greater than or equal to 150 mg/dL (1.6 mmol/L).
HDL stands for high-density lipoprotein. This breaks down and removes cholesterol from the body. It is sometimes referred to as the good cholesterol. This is defined as:
- In men—HDL levels less than 40 mg/dL (1.0 mmol/L)
- In women—HDL levels less than 50 mg/dL (1.3 mmol/L)
There are a number of tests that your doctor may do. Examples include:
- Waist circumference—a measurement around your hips and belly button
- Blood pressure
Your doctor will ask you to fast (not eat) after dinner the night before the test. The next morning, a blood sample will be tested for glucose levels.
These tests are also called lipid profile tests. After fasting, a blood sample will be taken to check for levels of:
- Total cholesterol
- LDL cholesterol—low-density lipoprotein (bad cholesterol)
- HDL cholesterol—high-density lipoprotein (good cholesterol)
