Health risk associated with being over weight

The following are some of the increased health risks associated with being over weight.

Heart Disease
The risk of heart attack, congestive heart failure, sudden cardiac death, angina or chest pain is increased in persons who are overweight or obese. High blood pressure is twice as common in adults who are obese than in those who are at a healthy weight. Obesity is associated with high triglycerides and decreased HDL cholesterol.

Stroke
Atherosclerosis, or narrowing of the arteries, which may lead to the formation of an arterial blood clot, is an important pre-condition of many strokes. Atherosclerosis is accelerated by high blood pressure, smoking, high cholesterol and lack of exercise. Obesity, especially morbid obesity is frequently associated with a high-fat diet, raised blood pressure and lack of exercise.

Type 2 Diabetes
A weight increase of 11-18 pounds raises a person's risk of developing type 2 diabetes to twice that of individuals who have not gained weight. Over 80 percent of people with diabetes are overweight or obese.

Cancers
Obesity is associated with an increased risk for some types of cancer.

Fatty Liver Disease
The main cause of non alcoholic fatty liver disease is insulin resistance, a metabolic disorder in which cells become insensitive to the effect of insulin. One of the most common risk factors for insulin resistance is obesity, especially central abdominal obesity. Studies indicate a correlation between body mass index (BMI) and the degree of liver damage. The higher the BMI the worse the liver disease.

Chronic Venous Insufficiency
Although obesity is not a direct cause of chronic venous insufficiency, it is an important risk factor. This is because obesity, especially morbid obesity, leads to raised blood pressure, a sedentary lifestyle and musculoskeletal problems (hampering mobility and use of leg muscles), all of which are contributory factors in the development of chronic venous insufficiency.

Gallbladder Disease
The risk of gallstones is approximately 3 times greater for obese patients than in non-obese people.

Breathing Problems
Obstructive sleep apnea (that is, interrupted breathing during sleeping) is more common in obese persons.

Deep Vein Thrombosis
Risk factors for deep vein thrombosis include prior history of the disease, vascular damage, hypertension and predisposition to blood clotting. Although obesity (BMI 30+) has traditionally been recognised as a risk factor for deep vein thrombosis and pulmonary embolism, experts now consider that the evidence supporting this association is inadequate, as much depends on other factors such as history, illness, immobility, and age.

Arthritis
Musculoskeletal disorders, including osteoarthritis, are much more prevalent among obese patients, especially patients diagnosed with severe clinical or morbid obesity. Health studies show that obesity is a strong predictor for symptoms of osteoarthritis, especially in the knees. The risk of osteoarthritis increases with every 2-pound gain in weight.
