If you are morbidly obese and have an accompanying medical condition such as Diabetes, your insurance may pay some or all of the cost of gastric bypass surgery for you. Gastric bypass surgery can cost anywhere from $13,000 to $30,000 in the United States. Many people without insurance have been traveling to South America, namely Mexico, to get the same surgical procedure at a fraction of the cost. In Mexico this same surgical procedure may only cost you between $4,500 and $11,500 and that includes a surgical package complete with recovery in a hotel for several days. Before committing to a surgeon for gastric bypass surgery you need to research who is the best and who is the cheapest to find the happy medium for you. If you are getting the surgery done and have insurance you need to make sure the surgeon is a participating physician on your insurance policy.
