Watch patients’ symptoms after obesity surgery

GPs should pay close attention to patient symptoms during the first few weeks after obesity surgery, according to US research.

Symptoms such as vomiting, confusion, lack of co-ordination and visual changes are all signs of the Wernicke encephalopathy syndrome, which is caused by a deficiency of thiamine.

However, treatment with vitamin B1 led to the recovery of the majority of patients involved in the study, with 40 per cent of the patients making a full recovery.

The researchers found that the syndrome was most common in people who experienced vomiting after obesity surgery.

Lead researcher Dr Sonal Singh, from Wake Forest University School of Medicine in North Carolina, said: ‘GPs should consider vitamin B1 deficiency and Wernicke encephalopathy when they see patients with these types complications after weight loss surgery.’
