Weight loss surgery can be too risky for the elderly

Reported by Susan Aldridge, PhD, medical journalist

Weight loss surgery may not be appropriate for older people as it is associated with a higher rate of complications.
Weight loss surgery is becoming more popular as populations struggle to cope with an epidemic of obesity and the associated health problems. But the surgical approach to weight loss is not without risks and, according to a new study, these may be magnified in those over 65.

Researchers at the University of Texas Southwestern, a leading center for weight loss surgery, have carried out the first-ever review of patients over 65 undergoing such procedures. They have found that weight loss surgery has an adverse event rate of 20 per cent and a death rate of 3.25 per cent in the over 65s. Men and those with heart failure are especially at risk. Complications included gastrointestinal, lung and heart problems. What is more, older patients tend to shed less weight through surgery and have less to gain in terms of improved health. For most, the risks of weight loss surgery may be greater than the potential benefits. Therefore, weight loss surgery should, ideally, be limited to those under 65, the researchers conclude.
