The suicidal tendencies of patients who have undergone gastric bypass makes it important for patients and doctors alike to understand the link between gastric bypass surgery and post-operative depression.

Psychological Profile of Pre-Operative Gastric Bypass Surgery Patients

In a study that examined individuals who were seeking gastric bypass surgery, about 66% of the participants were found to have a lifetime history of at least one axis I disorder while 29% of the participants were found to have at least one axis II disorders. Axis I disorders are clinical disorders while axis II disorders are personality disorders.  The study concluded that Diagnostic and Statistical Manual of Mental Disorders or DSM-IV psychiatric disorders are prevalent in individuals seeking gastric bypass surgery. 

Additionally, a positive connection was made between such psychiatric disorders and obesity and lower levels of health, thus leading the study to conclude as well that the presence of psychological illnesses in these individuals by virtue of their severe obesity may be the reason why they seek gastric bypass surgery.

Post-Operative Gastric Bypass Patients

Having a history of mental illness or psychological disorder is not the only reason why gastric bypass surgery patients have a strong tendency towards depression, as one study found that even patients with no history of depression prior to the operation subsequently developed depression after the procedure. There are many psychological triggers post-operation that lead to depression as well.

The most prevalent reaction that post-gastric bypass operation patients have is their disappointment that all their expectations prior to having the surgery did not materialize, as it is quite common for such patients to blame all their existing problems on their obesity. Other patients develop depression because they cannot seem to enjoy food the same way they used to as their stomachs can no longer hold the same amounts or kinds of food as before.
