Obesity Surgery Can Lead To Memory Loss, Other Problems 

Obesity Surgery Can Lead To Memory Loss, Other Problems: "Weight loss surgery, such as gastric bypass surgery, can lead to a vitamin deficiency that can cause memory loss and confusion, inability to coordinate movement, and other problems, according to a study published in the March 13, 2007, issue of Neurology®, the scientific journal of the American Academy of Neurology.

The syndrome, called Wernicke encephalopathy, affects the brain and nervous system when the body doesn't get enough vitamin B1, or thiamine. It can also cause vision problems, such as rapid eye movements.

The study found that the syndrome occurs most often in people who have frequent vomiting after the surgery. It usually occurs within one to three months after the surgery, although one case occurred 18 months after surgery.

The study reviewed the scientific literature for all reported cases of the syndrome occurring after obesity surgery. A total of 32 cases had been reported. Many of the people also had neurological symptoms that are not typical of Wernicke encephalopathy, such as seizures, deafness, psychosis, muscle weakness, and pain or numbness in the feet or hands."
