CBT is one of the most widely studied forms of psychotherapy, and it has been shown to be extremely effective for a variety of mental illnesses. Some of the issues that respond well to CBT include mood disorders, personality disorders, eating disorders, substance abuse, sleep disorders, and psychotic disorders. In some cases, CBT has been shown to be as effective or even more effective than medication. One of the interesting things that the scientific study of CBT has shown is that CBT actually changes the way the brain works, physically improving its function.

CBT differs from traditional psychotherapy in a few key ways. One of the most important distinctions is the emphasis on the power and responsibility of the patient in CBT. The patient will be encouraged to be the one asking the questions in CBT therapy, and most patients are assigned homework to complete outside of therapy sessions. There is a concept in CBT that everyone has power the power to change how they feel, even if they cannot control the situation, and this can be very empowering for patients. Because of this power shift, the therapist-client relationship is not as critical to success in CBT as it is in other modes of therapy. Patients should still get along well with their therapists, but they do not need a deep, dependent emotional connection to them. Finally, because CBT often treats a specific issue or problem, it is usually shorter in duration than traditional therapy. While some therapies may continue for years, CBT lasts on average just 16 sessions.

By far the most common of the gastric bypass surgeries is called Roux-en-Y. During this surgery, part of the stomach and small intestine are detached from the gastrointestinal tract, in order to make the tract smaller. The surgeon divides the stomach into two parts. The working stomach, at the end of the esophagus, is now tiny - only the size of a walnut. This makes patients feel full after eating a small amount of food. Then the small intestine is also divided, and after bypassing a section of the small intestine to reduce food absorption, the intestine is attached to the small stomach pouch. The patient now has a working stomach and intestine like before, only much smaller.

Because gastric bypass is used to treat extreme obesity, it can reduce the risk of some of the problems associated with obesity. Gastric bypass can help treat or reduce the risk for such conditions as heart disease, high blood pressure, sleep apnea, and type 2 diabetes. However, it is a major surgery and also carries risks itself. Any surgery can lead to infection, bleeding, or blood clots, and weight loss surgery in particular carries risks of leaks in the gastrointestinal system, malnutrition, bowel obstructions, and vomiting.

Typically patients are considered candidates for gastric bypass surgery if they have a BMI greater than 40, or sometimes if they have a BMI between 35 and 40 but are suffering from obesity-related illnesses such as diabetes. The outlook is generally good, with most patients losing between 50-75% of their excess weight in 1-2 years. However, patients must follow strict diet guidelines so that the stomach can heal, starting with no food at all, then followed by a liquid diet for some time. For many severely obese patients who have tried strict diets before without success, gastric bypass surgery is the tool that allows them to finally achieve their weight loss and health goals.
