What is metabolic syndrome?(Part 1)


Metabolic syndrome (MS) refers to a medical condition wherein you have a combination of abnormal findings in your health profile. These are: 1. increased blood pressure{systolic blood pressure of 130 millimeters of mercury (mmHg) or greater, or diastolic blood pressure of 85 mmHg or greater}, 2.a high fasting blood sugar {100 mg/dl or greater}, 3.excess body fat around the waist {waist circumference of 40 inches or over in men, and 35 inches or over in women}, 4. the level of HDL cholesterol is less than 40 mg/dl in men or less than 50 mg/dl in women, and 5.abnormal triglyceride levels {150 milligrams per deciliter of blood (mg/dl) or greater}. To label you as having MS, you should have at least three of these abnormalities in your medical profile[1,2].

Stricter definition

Based on the report of the National Heart, Lung, and Blood Institute/American Heart Association Conference on Scientific Issues Related to Definition, however, there were six components of MS which were identified. These are (1) abdominal obesity, (2) atherogenic dyslipidemia, (3) raised blood pressure, (4) insulin resistance with or without glucose intolerance, (5) proinflammatory state, and (6) prothrombotic state[3].

Abdominal obesity[3]

This refers to the increased waistline circumference as described in the preceding.

Atherogenic dyslipidemia[3]

When a substance is considered as atherogenic, this means that it can be deposited along the internal lining of your   blood vessel wall. When this takes place, your blood vessels become inelastic and rigid that eventually your blood pressure increases. Thus, as much as possible, these substances (cholesterol and triglycerides) need to be at normal levels in your blood in most of the times.

In the cholesterol profile, the factor which is more important is the level of the so-called HDL-cholesterol which is otherwise known as the “goodcholesterol. This is considered as “good” because it is responsible for the reverse cholesterol transport whose main function is to carry allcholesterol molecules from the different organs of your body back to the liver for elimination. If this is low, more cholesterol stays in your peripheral circulation, promoting possible attachment in the internal lining of your blood vessels. This becomes an atherogenic factor which should be addressed at the soonest possible time.

Raised blood pressure[3]

This refers to the elevation of your blood pressure as described in the preceding. Have your blood pressure checked regularly. When you find out that it is elevated, you need to consult your medical doctor for proper medication(s). It has to be lowered as soon as possible so that complications will not set in.

Insulin resistance [3]

The substance responsible for the absorption of glucose in your cells is the protein known as insulin. If you are suffering from MS, glucose is no longer sensitive to the action of insulin. Thus, in spite of having enough concentration of insulin in your cells, glucose is not absorbed and therefore not used.

Proinflammatory state[3]

If you are obese and your C-reactive protein (CRP) is elevated,aside from having inflammatory diseases, such as rheumatoid arthritis, it is greatly possible that you have MS. There are a number of causes of the CRP elevation, but obesity is one of the causes because excess adipose tissue releases inflammatory substances that will cause elevation of CRP[3].

Prothrombotic state[3]

When your plasma plasminogen activator inhibitor (PAI)-1 and your fibrinogen are elevated[3], then very likely you have MS. These are additional substances which indicate that some inflammatory substances are highly elevated in your body, promoting the development of cardiovascular diseases.
