Obesity Vs Dyslipidemia

Etymology and Pronunciation

Dyslipidemia (dis-lip-uh-dee-mee-uh)
dys - Greek for "abnormal" or "impaired"
lipid - Greek for "fat"
-emia - Greek suffix for "blood"


Dyslipidemia refers to a condition where there is an abnormal amount or distribution of fats (lipids) in the blood, such as high levels of cholesterol or triglycerides. This condition is often associated with an increased risk of cardiovascular disease, such as heart attack or stroke.

The term "dyslipidemia" is relatively modern and was first used in medical literature in the 1970s. Before that, the condition was often referred to as "hyperlipidemia" which simply means high levels of lipids in the blood. However, the term dyslipidemia is now more commonly used because it encompasses both high and low levels of lipids, as well as abnormalities in their composition and distribution.

Modern Understanding

Obesity is a medical condition characterized by excess body fat that can negatively affect a person's health. It is typically diagnosed by measuring a person's body mass index (BMI), which is calculated by dividing their weight in kilograms by the square of their height in meters. According to the World Health Organization, obesity is defined as having a body mass index (BMI) of 30 or higher.

Dyslipidemia refers to an abnormal lipid profile in the blood, which can include high levels of total cholesterol, LDL (low-density lipoprotein) cholesterol (also known as "bad" cholesterol), triglycerides, or low levels of HDL (high-density lipoprotein) cholesterol (also known as "good" cholesterol).

Dyslipidemia is often associated with obesity, a sedentary lifestyle, and an unhealthy diet, although it can also be caused by genetic factors, certain medications, and medical conditions such as hypothyroidism, kidney disease, and liver disease.

Elevated levels of LDL cholesterol and triglycerides, combined with low levels of HDL cholesterol, increase the risk of cardiovascular disease, including heart attack, stroke, and peripheral vascular disease. Dyslipidemia can also contribute to other medical conditions such as diabetes and fatty liver disease.

Is obesity and dyslipidemia?

No, obesity and dyslipidemia are not the same thing, although they are often associated with each other. Obesity is defined as having an excess amount of body fat, while dyslipidemia refers to abnormal levels of lipids (fats) in the blood, such as high levels of cholesterol or triglycerides. Obesity can contribute to the development of dyslipidemia by increasing the amount of free fatty acids in the blood, which can in turn cause insulin resistance and increased production of triglycerides and LDL cholesterol. However, dyslipidemia can also occur in people who are not overweight or obese, and may be caused by other factors such as genetic predisposition or certain medical conditions.


1. Genetics: Obesity can be hereditary, and certain genetic factors can increase the likelihood of obesity in some individuals.
2. Lifestyle factors: A sedentary lifestyle with little physical activity, along with poor dietary habits, is a major cause of obesity. Consuming high-calorie, high-fat, and high-sugar foods, as well as large portion sizes, can contribute to weight gain.
3. Environmental factors: The environment in which a person lives can also play a role in obesity. For example, living in a neighborhood with limited access to healthy food options or safe places to exercise can make it difficult to maintain a healthy weight.
4. Medical conditions: Certain medical conditions, such as hypothyroidism, Cushing's syndrome, and polycystic ovary syndrome (PCOS), can cause obesity.
5. Medications: Certain medications, such as antidepressants, antipsychotics, and corticosteroids, can lead to weight gain.
6. Psychological factors: Stress, depression, and other emotional issues can contribute to overeating and unhealthy eating habits.


- Lifestyle changes: Making healthy lifestyle changes, such as adopting a balanced diet and increasing physical activity, is often the first step in treating obesity. This can involve working with a dietitian or nutritionist to develop a healthy eating plan, and gradually increasing exercise levels with guidance from a healthcare professional.
- Medications: Certain medications may be prescribed to help manage obesity, but they are typically reserved for individuals with a BMI of 30 or higher, or those with a BMI of 27 or higher and an obesity-related health condition.
- Bariatric surgery: In cases of severe obesity, bariatric surgery may be recommended as a last resort. This involves altering the digestive system to reduce food intake or the body's ability to absorb calories.
- Behavioral therapy: Behavioral therapy can be used to help individuals with obesity change their habits and develop healthy lifestyle habits that will help them maintain a healthy weight. This may involve working with a psychologist or counselor to identify triggers for overeating and develop coping strategies to manage these triggers.
- Support groups: Joining a support group or seeking support from family and friends can help individuals with obesity stay motivated and on track with their weight loss goals.
