Obese people are susceptible to health complications and diseases, such as cardiovascular disorders, type 2 diabetes, hypertension, osteoarthritis, gallstone, hypoxia, certain cancers and even mental and intellectual and disabilities. Bariatric surgery is a prevalent weight loss approach, predominantly in situations where prior efforts towards weight reduction proved ineffective. It engages a modification in the digestive system by limiting food consumption, leading to decreased stomach capacity and physiological ability for nutrient absorption. Since obesity associates with morbidity, the pre, intra and post-operative care and post-discharge rehabilitation comprise key determining factors for a successful bariatric surgery. The process may involve short- and long-term recuperation in nursing homes and hospitals, which accord significant impact on patient’s well-being and psychology. Nursing care for these individuals with unique physiological and emotional problems is often an arduous task, requiring environmental modifications, mobility training facilities and bariatric program and care-related equipment. Special attention is required from nursing professionals towards minimum fall and injury, management of related problems, including arterial venous insufficiency, neuropathic ulcers, seromas, anastomotic leaks, abdominal wound dehiscence and post-surgery complications, together with increased hygiene and skin care. Through an interdisciplinary approach, regular monitoring of diet, nutritional parameters, including weight change, Body Mass Index, energy and protein requirement, medication, clinical complications, functional mobility, psychosocial issues, etc. can be essential. Overall, the current review enlightens the importance of bariatric surgery, and particularly offers critical assessment of nursing care systems and specialized rehabilitation services addressing physical and mental health care in obese and post-operative patients.
