Why Should I Treat Obesity ?
Obesity increases the risk of developing several health problems like high blood pressure, insulin resistance, type 2 diabetes, coronary artery disease (heart attacks), cerebrovascular disease (stroke), gout, gallstones, colon cancer, sleep apnea and non alcoholic fatty liver disease. Obesity leads to various ailments and psychological problems. The muscles of obese persons are weak and flabby. Arthritis is also common in obese persons. The weight bearing joints are under constant stress and strain due to excess weight of the body. Blood vessels of obese persons get constricted due to excess cholesterol, which form plaques (atheromas). This leads to high blood pressure, stabbing pain in the chest (angina pectoris), heart attacks and strokes. The digestive system of obese persons is prone to diseases like diverticular pathologies. Gall stones may be formed due to excess cholesterol. Cancers, diabetes are all products of obesity. Obesity also creates problems during pregnancy.
The various diseases and complications due to obesity shorten the lifespan of individuals and can lead to premature death. Mortality and morbidity are both to associate closely with obesity. An obese person not only suffers physical pains but also suffers psychological trauma. He feels inferior, and there may be psychological problems as he is often ridiculed and teased.

Heart Disease and Stroke

Heart disease and stroke are the leading causes of death and disability for both men and women. Overweight people are more likely to have high blood pressure, a major risk factor for heart disease and stroke, than people who are not overweight. Very high blood levels of cholesterol and triglycerides (blood fats) can also lead to heart disease and often are linked to being overweight. Being overweight also contributes to angina (chest pain caused by decreased oxygen to the heart) and sudden death from heart disease or stroke without any signs or symptoms. The good news is that losing a small amount of weight can reduce your chances of developing heart disease or a stroke. Reducing your weight by 10 percent can decrease your chance of developing heart disease by improving how your heart works, blood pressure, and levels of blood cholesterol and triglycerides.

Atherosclerosis or fatty deposits in blood vessels:

Cholesterol is carried in the blood as two compounds: Low-density lipoproteins (LDL) and High-density lipoproteins (HDL). HDL is also called the ‘good’ cholesterol and LDL is also called the ‘bad’ cholesterol. Obesity is associated with low levels of good (high-density lipoprotein) cholesterol and high levels of bad (LDL) cholesterol. When cholesterol levels are high, some of the cholesterol is deposited on the walls of the blood vessels. Cholesterol deposits reduce the elasticity of blood vessels, narrows blood vessels & decreases blood flow. All these changes lead to atherosclerosis and an increased risk of heart disease & stroke.

High blood pressure:

Multiple factors are responsible for increase in blood pressure in obesity. Weight gain is associated with decrease in elasticity of blood vessels & increase heart rate. Excess calories are deposited in body as fat in fatty tissue. This fatty tissue increases demand for oxygen & nutrients, which in turn increases amount of blood circulating in the body. More blood traveling through arteries adds pressure on walls of arteries leading to increase in blood pressure. Also, obesity increases level of insulin in body. Insulin causes sodium & water retention in body, which results in increase in blood volume & extra pressure on arteries. All of these factors can increase blood pressure.

Diabetes

Non insulin-dependent diabetes mellitus (type 2 diabetes) is the most common type of diabetes. Type 2 diabetes reduces your body’s ability to control your blood sugar. Insulin is required for the entry of sugar (glucose) into body cells from blood. Excess body fat in obesity makes body resistant to insulin. Because of this insulin resistance, sugar will remain in blood, which will lead to increase in blood sugar or diabetes. High amount of sugar in blood leads to complications in kidney, eyes, blood vessel, and heart. It is a major cause of early death, heart disease, kidney disease, stroke, and blindness. Overweight people are twice as likely to develop type 2 diabetes as people who are not overweight. You can reduce your risk of developing this type of diabetes by losing weight and by increasing your physical activity. If you have type 2 diabetes, losing weight and becoming more physically active can help control your blood sugar levels. If you use medicine to control your blood sugar, weight loss and physical activity may make it possible for your doctor to decrease the amount of medication you need.

Cancer

Several types of cancer are associated with being overweight. In women, these include cancer of the uterus, gallbladder, cervix, ovary, breast, and colon. Overweight men are at greater risk for developing cancer of the colon, rectum, and prostate. For some types of cancer, such as colon or breast, it is not clear whether the increased risk is due to the extra weight or to a high-fat and high-calorie diet.

Sleep Apnea

Sleep apnea can cause a person to stop breathing for short periods during sleep and to snore heavily. Sleep apnea is a serious condition that is closely associated with being overweight. Sleep apnea may cause daytime sleepiness and even heart failure. The risk for sleep apnea increases with higher body weights. Weight loss usually improves sleep apnea.

Osteoarthritis

Osteoarthritis is a common joint disorder that most often affects the joints in your knees, hips, and lower back. Extra weight appears to increase the risk of osteoarthritis by placing extra pressure on these joints and wearing away the cartilage (tissue that cushions the joints) that normally protects them. Weight loss can decrease stress on the knees, hips, and lower back and may improve the symptoms of osteoarthritis.

Gout

Gout is a joint disease caused by high levels of uric acid in the blood. Uric acid sometimes forms into solid stone or crystal masses that become deposited in the joints. Gout is more common in overweight people and the risk of developing the disorder increases with higher body weights.

Gallbladder Disease

Gallbladder disease and gallstones are more common if you are overweight. Your risk of disease increases as your weight increases. It is not clear how being overweight may cause gallbladder disease. Weight loss itself, particularly rapid weight loss or loss of a large amount of weight, can actually increase your chances of developing gallstones. Modest, slow weight loss of about 1 pound a week is less likely to cause gallstones.

Fatty liver disease (Non alcoholic fatty liver):

Obesity increases the risk of developing fatty liver disease due to accumulation of fat in liver. These fatty deposits in liver can lead to inflammation & scarring of the liver called non-alcoholic fatty liver disease. Serious complication of this scarring is cirrhosis of liver
