Metabolic Syndrome

Question 1

What is metabolic syndrome?

Answer 1

Metabolic syndrome is a cluster of risk factors contributing to higher incidence of diabetes, cardiovascular events, and mortality.

Question 2

Who coined the term “metabolic syndrome” and when?

Answer 2

The term “metabolic syndrome” or “syndrome X” was first coined by Gerald Reaven in 1988.

Question 3

How does a syndrome differ from a disease?

Answer 3

A syndrome is an aggregate of symptoms and signs associated with an underlying morbid process, producing the picture of a disease.

Question 4

What are the core components of metabolic syndrome?

Answer 4

The core components include obesity, hypoglycemia, dyslipidemia, and hypertension.

Question 5

What criteria did the WHO establish for diagnosing metabolic syndrome?

Answer 5

The WHO established criteria based on insulin resistance in the 1990s.

Question 6

What does the ATPIII recommend for diagnosing metabolic syndrome?

Answer 6

ATPIII recommends that three out of five specific factors must be present for a diagnosis of metabolic syndrome.

Question 7

What are the diagnostic criteria components for metabolic syndrome?

Answer 7

1) Elevated waist circumference
2) Elevated triglycerides
3) Low HDL cholesterol
4) Elevated blood pressure
5) Elevated fasting glucose levels

Question 8

How is waist circumference measured for metabolic syndrome diagnosis?

Answer 8

It is measured using a tape around the abdomen at the level of the iliac crest, during expiration.

Question 9

Why is a single waist circumference definition problematic?

Answer 9

Different races and ethnic groups have varying susceptibility to metabolic syndrome, making a universal cutoff ineffective.

Question 10

What is the relationship between triglycerides and cardiovascular risk?

Answer 10

Elevated plasma triglycerides are positively and independently associated with cardiovascular risk factors.

Question 11

What role does HDL cholesterol play in cardiovascular health?

Answer 11

HDL (good cholesterol) helps transport lipids back to the liver for disposal; low levels are a negative marker for cardiovascular health.

Question 12

What additional factors enhance risk for coronary heart disease and type 2 diabetes?

Answer 12

Chronic proinflammatory states, hormonal dysregulation, excess liver fat, and abnormal fat distribution.

Question 13

How can hormonal factors affect metabolic syndrome?

Answer 13

Hormonal dysregulation, particularly in the corticosteroid axis, can be strongly associated with metabolic syndrome.

Question 14

What is a chronic proinflammatory state in the context of metabolic syndrome?

Answer 14

It is indicated by elevated inflammatory cytokines and can enhance the risk for various conditions associated with metabolic syndrome.

Question 15

Why is understanding metabolic syndrome important for public health?

Answer 15

It helps in the diagnosis, treatment, prognosis, and understanding the prevalence of non-communicable diseases.

Question 31

What factors primarily influence the pathophysiology of metabolic syndrome?

Answer 31

Genetic factors and environmental factors, including diet, lifestyle, and activity levels.

Question 32

What effect does an unhealthy lifestyle have on body composition related to metabolic syndrome?

Answer 32

It can lead to an increase in adipose tissue and visceral obesity.

Question 33

What are some circulating pro-inflammatory cytokines associated with metabolic syndrome?

Answer 33

Interleukin 6 and TNF alpha.

Question 34

How does stress contribute to metabolic syndrome?

Answer 34

Stress can increase appetite, lead to visceral obesity, raise cortisol levels, and dysregulate the renin-angiotensin system.

Question 35

What is insulin resistance?

Answer 35

A condition where peripheral tissues (like muscles and fat) are unable to utilize insulin effectively, leading to elevated blood glucose levels.

Question 36

What are the long-term consequences of insulin resistance?

Answer 36

It can lead to increased oxidative stress, the release of reactive oxygen species, and dysregulation of protein synthesis at the cellular level.

Many risk factors are preventable and manageable with early intervention, reducing the risk of developing serious health issues.

Question 41

What is the overall conclusion regarding the pathophysiology of metabolic syndrome?

Answer 41

It is a complex process with multiple underlying mechanisms contributing to its development, highlighting the need for early identification and management.

Question 42
