Nutritional follow-up of patients after obesity surgery: best practice.

Obesity surgery is an appropriate treatment option for patients with severe and complex obesity and helps in the improvement of comorbidities. In the first 2 years following surgery, follow-up is provided by the obesity surgery centre. Ongoing care is then usually returned to the general practitioner. Patients need access to ongoing support and monitoring otherwise may be at risk of developing nutritional deficiencies such as anaemia or protein malnutrition. The British Obesity and Metabolic Surgery Society have developed guidelines on nutritional monitoring and nutritional supplements to support both bariatric centres and general practitioners. The Royal College of General Practitioners and BOMSS have worked collaboratively to develop Ten Top Tips for the management of obesity surgery patients to aid with the long-term management in primary care. Women, planning to get pregnant, need access to preconception advice and additional monitoring during pregnancy. It is essential that long-term data are collected and inputted into the National Bariatric Surgery Register. Obesity surgery improves comorbidities; however, patients must have access to long-term nutritional monitoring.
