Weight regain may occur with all three of the most common
procedures (Roux-en-Y gastric bypass, sleeve gastrectomy and gastric banding),
and it depends on nutritional, psychological and surgeryrelated factors.
There are very few studies directly investigating the
clinical factors determining weight regain. Poor outcome after the first surgery may happen as follow-up studies
underline stressing the importance of psychiatric or psychological factors in
inducing it.
The persistence of body shape concern and uneasiness after
weight loss determining the inability to recognize one-self as an individual
with own desire and capacity, is considered a risk factor for weight regain.
Psychotherapy is the most useful instrument to reconstruct body image and
achieve weight maintenance.
