About Metabolic Syndrome

Metabolic syndrome is the name for a group of risk factors that raises your risk for heart disease and other health problems, such as diabetes and stroke.

The term "metabolic" refers to the biochemical processes involved in the body's normal functioning. Risk factors are traits, conditions, or habits that increase your chance of developing a disease.

In this article, "heart disease" refers to coronary heart disease (CHD). CHD is a condition in which a waxy substance called plaque builds up inside the coronary (heart) arteries.

Plaque hardens and narrows the arteries, reducing blood flow to your heart muscle. This can lead to chest pain, a heart attack, heart damage, or even death.

Metabolic Risk Factors

The five conditions described below are metabolic risk factors. You can have any one of these risk factors by itself, but they tend to occur together. You must have at least three metabolic risk factors to be diagnosed with metabolic syndrome....Read more about Metabolic Syndrome

Lifestyle Interventions for Four Conditions: Type 2 Diabetes, Metabolic Syndrome, Breast Cancer, and Prostate Cancer [Internet]

To synthesize evidence from randomized controlled trials (RCTs) on the effectiveness of lifestyle interventions to control progression of type 2 diabetes, progression to diabetes from metabolic syndrome, or recurrence of breast cancer and prostate cancer. Lifestyle interventions were defined as any intervention that included exercise, diet, and at least one other component (e.g., counseling, stress management, smoking cessation).

Nutritional interventions for survivors of childhood cancer

Survivors of childhood cancer are at a higher risk of chronic health conditions such as, osteoporosis, metabolic syndrome (including obesity and type II diabetes), and cardiovascular disease. These diseases have the potential to be reduced or prevented with targeted nutritional interventions.

The effect of antidepressants for women with polycystic ovary syndrome

The prevalence of depression in women with polycystic ovary syndrome (PCOS) is high; a study has shown it to be four times that of women without PCOS. Therefore, systematic evaluation of the effectiveness and safety of antidepressants for women with PCOS is important. We found no evidence to support the use or non‐use of antidepressants in women with PCOS, with or without depression. Well‐designed and well‐conducted randomised controlled trials with double blinding should be conducted.

Terms to know

Glucose (Dextrose)
A simple sugar the body manufactures from carbohydrates in the diet. Glucose is the body's main source of energy.
High-Density Lipoprotein Cholesterol (HDL Cholesterol)
HDL cholesterol stands for high-density lipoprotein cholesterol, which is a fat found in the blood that takes extra cholesterol from the blood to the liver for removal. Sometimes called "good" cholesterol.
Hypercholesterolemia (High Blood Cholesterol)
Abnormally high levels of cholesterol in the blood.
Hypertension (High Blood Pressure)
A condition present when blood flows through the blood vessels with a force greater than normal. Also called high blood pressure. Hypertension can strain the heart, damage blood vessels, and increase the risk of heart attack, stroke, kidney problems, and death.
Insulin Resistance
The body's inability to respond to and use the insulin it produces. Insulin resistance may be linked to obesity, hypertension, and high levels of fat in the blood.
Triglycerides
One of the major forms of fat that is produced in the liver and found in the blood.
