Thinking about weight loss surgery? You're not alone. Over two-thirds of Americans are overweight or obese. Many are looking for ways to lower their bodyweight and enjoy a healthier, more active lifestyle. A fast surgical procedure seems like a great option. But, for the vast majority of people, weight loss surgery should be a last resort.

One of the most common types of weight loss surgery is liposuction, a procedure that removes excess fat from the waistline. Thousands of people - mostly women - undergo liposuction surgery every year. For many, it appears to be a much easier alternative to diet and exercise. Yet recent studies show that removing abdominal fat with liposuction provides almost none of the health benefits of "normal" weight loss: lowered levels of blood sugar, insulin and inflammation-related biomarkers, not to mention increased cardiovascular fitness, improved muscle tone, stronger bones, etc.

Another little-known problem with liposuction weight loss surgery: over 40% of patients regain the weight they lose from the procedure. Why? Simply because they make no healthy lifestyle changes. Some even believe that they can exercise less and eat more now that they have fewer abdominal fat cells. Obviously this isn't true and thousands of people find that out the hard way.

Other types of weight loss surgery are designed for the severely obese - generally those people with a body mass index (BMI) of 40 or higher. These surgeries, which include gastric bypass and various "banding" and "stapling" procedures, have helped many formerly-obese people enjoy a higher-quality of life. However, all of these operations involve a considerable amount of risk.

Some of the risks associated with weight loss surgery include:

Death - According to the Mayo Clinic, about one in 200 to 300 people who has gastric bypass surgery dies from the procedure.

Post-surgery complications - Some weight loss surgery patients experience severe complications such as internal bleeding, infections, and blood clots. Others have to undergo follow-up procedures to correct complications such as abdominal hernias.

Gallstones - More than a third of patients develop gallstones as a result of losing large amounts of bodyweight following a weight loss surgery procedure.

Nutrient deficiencies - Some weight loss surgeries disrupt the digestion process. Without careful dietary supplementation this can lead to deficiencies in many important nutrients, especially vitamins B12 and D, iron, calcium, and folate.

Anyone considering weight loss surgery needs to weigh the risks against the benefits. They also need to realize that these extreme procedures are not cosmetic. Most patients only end up losing about 30% of their bodyweight and remain overweight for life. Simply put, weight loss surgery alone will not make you thin and beautiful. Yes, if you are extremely overweight, it may provide tremendous health benefits. But if you're just looking for a way to get thin without the "hassles" of healthy diet and regular exercise you better think again.
