Access to psychological services should be part of obesity treatment, according to the director of the British Obesity Surgery Patients Association (BOSPA).
Following research from the charity Diabetes UK, BOSPA director Chrissie Palmer, highlighted the fact that "depression can be a side effect of obesity".
The Diabetes UK research revealed that there is a medical link between people who are undergoing gastric band surgery to lose weight and an increased risk of low self-esteem and mental health issues.
According to a report cited by the charity, the depression problems were usually brought about by the loss of food as a coping mechanism.
Ms Palmer commented: "Depression or other psychological disorders, for example body dimorphic, are unfortunately becoming more common because as we lose weight, we are unlocked from our fat prison and can talk about feelings, relationships et cetera."
She added: "Bariatric patients should be able to access appropriate psychological services should they need them at any stage of their weight loss journey."
