Metabolic (met-ah-BOL-ik) 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 (plak) 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.
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.
Your risk for heart disease, diabetes, and stroke increases with the number of metabolic risk factors you have. In general, a person who has metabolic syndrome is twice as likely to develop heart disease and five times as likely to develop diabetes as someone who doesn't have metabolic syndrome.
Other risk factors, besides those described above, also increase your risk for heart disease. For example, a high LDL cholesterol level and smoking are major risk factors for heart disease, but they aren't part of metabolic syndrome.
Having even one risk factor raises your risk for heart disease. You should try to control every risk factor you can to reduce your risk.
The risk of having metabolic syndrome is closely linked to overweight and obesity and a lack of physical activity. Insulin resistance also may increase your risk for metabolic syndrome.
Insulin resistance is a condition in which the body can't use its insulin properly. Insulin is a hormone that helps move blood sugar into cells where it's used for energy. Insulin resistance can lead to high blood sugar levels, and it's closely linked to overweight and obesity.
Genetics (ethnicity and family history) and older age are other factors that may play a role in causing metabolic syndrome.
Metabolic syndrome is becoming more common due to a rise in obesity rates among adults. In the future, metabolic syndrome may overtake smoking as the leading risk factor for heart disease.
It is possible to prevent or delay metabolic syndrome, mainly with lifestyle changes. A healthy lifestyle is a lifelong commitment. Successfully controlling metabolic syndrome requires long-term effort and teamwork with your health care providers.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Metabolic Syndrome, visit www.clinicaltrials.gov.

NIH launches trial to evaluate anti-inflammatory treatment for preventing heart attacks, strokes, and cardiovascular deaths
An international multi-site trial has launched to determine whether a common anti-inflammatory drug can reduce heart attacks, strokes, and deaths due to cardiovascular disease in people at high risk for them.
The NHLBI updates Health Topics articles on a biennial cycle based on a thorough review of research findings and new literature. The articles also are updated as needed if important new research is published. The date on each Health Topics article reflects when the content was originally posted or last revised.
