Health Benefits

It’s obvious to many people who have lived with morbid obesity for years that the disease has a severe negative impact on quality of life. Because of morbid obesity, you may choose not to participate in certain activities. You may feel that you have limited career choices.

What you may not know is that morbid obesity has been found to affect the quality of your health and the length of your life.4

Morbid obesity has been linked to several serious and life-threatening diseases. These co-morbid conditions include type 2 diabetesheart disease and high blood pressureacid reflux/GERD, and cancer. Most of these conditions do not develop for years. So many people living with morbid obesity may have one or more of these health issues without even realizing it.

Bariatric surgery may offer you a whole new outlook on health…

  • One study found that gastric bypass surgery reduced the total number of co-morbid conditions of participating patients by 96%.5
  • Many surgeons recommended bariatric surgery as a treatment option for type 2 diabetes.12 In some cases, resolution of type 2 diabetes occurred within days of the surgery.4
  • A meta-analysis stated that several studies found that bariatric surgery patients felt better, spent more time doing recreational and physical activities, benefited from enhanced productivity and economic opportunities, and had more self-confidence than they did prior to surgery.4

Type 2 Diabetes

Long-term Complications

Type 2 diabetes can be a lifelong condition. Type 2 diabetes is an increasingly widespread health issue in the U.S. and has serious long-term consequences. You may want to compare bariatric surgery’s high resolution rates for type 2 diabetes to the long-term effects of the condition.

People with type 2 diabetes are at risk for developing:

  • Heart disease or suffer strokes due to poor circulation
  • Kidney disease and eventually kidney failure, which requires either a kidney transplant or dialysis
  • Nerve damage which can lead to digestive problems, bladder problems, sexual dysfunction, and numbness and tingling
  • Foot problems including blisters, ulcers, and poor circulation, which can lead to amputation
  • Eye complications such as glaucoma, cataracts, and nerve damage, which can lead to blindness

Heart Disease and High Blood Pressure

Long-term Complications of Heart Disease and High Blood Pressure

Heart disease and high blood pressure are related health conditions. High blood pressure indicates that your heart is straining to pump blood throughout your circulatory system and can lead to health disorders such as heart disease.

Heart disease is an umbrella term for several diseases that affect the heart and the circulatory system. Heart disease can be quite serious and fatal. You may want to compare bariatric surgery’s high resolution rates for heart disease to the long-term effects of these conditions.

People living with morbid obesity are at risk for developing heart disease and high blood pressure, including conditions such as:

  • Coronary artery disease which occurs when the coronary arteries become hardened and narrowed by fatty material; there are rarely any signs or symptoms, so many people with this disease have lived with it for years before the first onset of symptoms, such as a “sudden” heart attack
  • Heart attack which occurs when the heart’s blood supply is interrupted and can damage or completely stop the heart
  • Angina which occurs when the heart does not get enough blood and feels like pressure or squeezing in the chest, shoulders, arms, neck, jaw, or back
  • Arrhythmias which are irregular heartbeats, depending on the type, arrhythmias can lead to death
  • Heart disease including bleeding along artery walls, hardening of the arteries, and heart attack
  • Stroke which is an interruption or blockage of blood to the brain
  • Kidney damage and kidney failure due to damaged blood vessels and which can require a kidney transplant or dialysis
  • Vision loss due to blocked blood vessels to the eye

High Cholesterol

Long-term Complications

Cholesterol is a soft, waxy substance found in all parts of the body. High cholesterol can be harmful and is associated with serious health conditions. You may want to compare bariatric surgery’s high improvement rates for this condition to the long-term effects of high cholesterol.

People with high cholesterol are at risk for developing:

  • Heart disease including hardening of the arteries (atherosclerosis), which is a principle cause of coronary heart disease, and heart attack
  • Stroke which is an interruption or blockage of blood to the brain

Obstructive Sleep Apnea

Long-term Complications

Obstructive sleep apnea is a sleep disorder with symptoms of loud snoring and long pauses in breathing. Often the person with obstructive sleep apnea is unaware of their condition until they’re told by a family member or friend. Obstructive sleep apnea is linked to several serious conditions and experiences. You may want to compare bariatric surgery’s high resolution rates for this condition to the long-term effects of obstructive sleep apnea.

People with obstructive sleep apnea are at risk for:

  • Heart disease due to low oxygen levels in blood
  • High blood pressure due to low oxygen levels in blood
  • Heart attack which occurs because of low oxygen levels in blood
  • Daytime drowsiness which can lower job performance or lead to accidents such as serious car crashes

Acid Reflux/GERD

Long-term Complications

Acid reflux, also known as GERD, occurs when the valve between the stomach and the esophagus is not working. Stomach acid splashes up into the esophagus, which can damage it and lead to painful conditions and cancer. You may want to compare bariatric surgery’s high resolution rates for acid reflux to the long-term effects of this condition.

People with acid reflux are at risk for developing:

  • Esophagitis, inflammation of the esophagus, which can cause difficulty swallowing, ulcers, and scarring
  • Barrett’s esophagus which occurs because the lining of the esophagus is damaged by stomach acid and can lead to esophageal cancer
  • Esophageal cancer (adenocarcinoma) is associated with a low survival rate: only 12% of esophageal cancer patients survive for more than five years8

Morbid Obesity and Cancer Risks

Several studies have been conducted to examine the link between morbid obesity and cancer.

In 2001, experts at the National Cancer Institute® concluded that several cancers are associated with obesity:14

  • Colon cancer
  • Breast cancer (postmenopausal)
  • Endometrial cancer (lining of the uterus)
  • Kidney cancer
  • Esophageal cancer (adenocarcinoma)

In 2003, an article in the New England Journal of Medicine estimated that obesity could account for:15

  • 14% of all deaths from cancer in men
  • 20% of all deaths from cancer in women

A Proven Treatment Option

Several clinical studies of bariatric surgery show that surgery improved life expectancy in patients by at least 29 to 89 percent.6,16,17,18

A Note on Relative Risk

The charts below refer to “relative risk,” which compares how likely an event is to occur to a person versus another person. The charts show how much more likely a person with morbid obesity is to develop cancer or die from cancer versus a person with a healthy weight.

Cancer and obesity are linked, but there is hope:

  • One recent study that examined the effect of intentional weight loss found that women who experienced intentional weight loss of 20 or more pounds and were not currently overweight had cancer rates at the level of healthy women who never lost weight.14
  • Several clinical studies found that bariatric surgery reduced mortality in patients by 29% to 89% when compared to a group of people living with morbid obesity who had not had the surgery.6,16,17,18

Depression

Symptoms and Signs

Clinical depression is a mood disorder during which feelings of sadness, loss, anger, or frustration interfere with everyday living for extended periods of time. This is very different from having a bad day, feeling unhappy, or just “down in the dumps.” You may want to consider bariatric surgery’s improvement rates for this condition.

People with depression may experience:

      • Lower quality of life
      • Sadness
      • Lack of interest in, and withdrawal from, usual activities
      • Feelings of hopelessness
      • Lack of energy
      • Difficulty concentrating
      • Difficulty making decisions
      • Insomnia or excessive sleep
      • Stomach aches and digestive problems
      • Sexual dysfunction
      • Thoughts of death, suicide, or self-mutilation

Osteoarthritis and Joint Pain

Long-term Complications

Osteoarthritis is also known as degenerative joint disease. It results in the breakdown of the cartilage in the joints. Without cartilage, the bones rub against each other, and the joints become stiff and painful. You may want to consider bariatric surgery’s resolution rates for osteoarthritis and the long-term effects of the condition.

People with osteoarthritis are at risk for developing:

      • Muscular atrophy due to the reduced range of movement caused by pain and stiffness in the joints
      • Loss of mobility because osteoarthritis commonly occurs in the hips, knees, and spine, making it harder and more painful to walk and move around
      • Joint swelling caused by the friction of bones rubbing against each other

Female Reproductive Health

You may want to consider bariatric surgery’s resolution rates for these conditions and the long-term effects of reproductive health.

Women living with morbid obesity may experience certain reproductive health issues, such as:

      • Menstrual dysfunction due to polycystic ovarian syndrome (PCOS)
      • Excess hair (also known as hirsutism) due to PCOS
      • Infertility

In a study of 28 patients with Polycystic Ovarian Syndrome who had gastric bypass surgery, the following results were reported.

Additional Health Benefits

You may want to compare bariatric surgery’s resolution rates for these conditions to the long-term effects of these health issues.

Metabolic Syndrome

Also known as syndrome X, metabolic syndrome is a group of risk factors including high blood pressure, high blood sugar, unhealthy cholesterol levels, and abdominal obesity. People with metabolic syndrome are at risk for developing:

      • Heart disease, including hardening of the arteries, which can lead to heart attacks and stroke
      • Diabetes which can lead to kidney failure, amputation of feet, and blindness

80% of gastric bypass patients experienced complete resolution of metabolic syndrome after surgery.21

Migraines

Migraines are throbbing headaches that can last up to 48 hours and are often accompanied by vomiting, nausea, loss of appetite, tiredness, and sensitivity to light and sound. While migraines are not generally considered a significant threat to overall health, they are associated with a lower quality of life.

People with migraines are at risk for developing:

      • Stroke, an extremely rare complication of severe migraines.

57% of gastric bypass patients experienced complete resolution of migraines after surgery.2

Venous Stasis Disease

Venous stasis disease occurs when the veins have problems sending blood from the legs back to the heart. Fluid seeps out of the overfilled veins into surrounding leg tissues and cause tissue breakdown and ulcers. And because skin ulcers are the result of poor blood circulation, these wounds are often slow to heal. People with venous stasis disease may experience:

      • Painful ulcers
      • Rashes
      • Leg pains
      • Dark red or purple skin over the affected area
      • Skin may become thickened, dry, and itchy

95% of gastric bypass patients experienced complete resolution of venous stasis disease after surgery.22

Pseudotumor Cerebri

Pseudotumor cerebri is a condition that appears to be a tumor—but it is not. The major symptom is increased pressure within the skull; other symptoms include headache, buzzing sound in the ears, dizziness, and nausea.

      • Vision loss can occur with this condition.

96% of gastric bypass patients experienced complete resolution of pseudotumor cerebri after surgery.22,23
