The emergence of bariatric surgeries and their significant impact on the management of morbid obesity have brought about numerous healthcare and economic benefits through surgical interventions. However, it is essential to acknowledge that post-surgical complications, particularly those related to malnutrition, are widespread and often prone to misdiagnosis or inadequate treatment. Recent evidence suggests a rise in malnutrition-related complications, while patient adherence to supplementation and post-operative monitoring fails to match this upward trend. Given the increasing popularity of bariatric surgery as an obesity treatment, it becomes essential to recognize and understand these complications and their associated symptoms of nutritional deficiencies. This undertaking aims to examine the malnutrition complications following bariatric surgery, emphasizing the crucial role of the interprofessional team in evaluating and addressing these issues in patients.

Bariatric surgery is an effective treatment that produces significant and sustained improvement in metabolic disorders and comorbidities associated with obesity.[1] However, bariatric surgery is associated with an increased risk of malnutrition post-operatively. Moreover, bariatric surgery can exacerbate preexisting nutritional deficiencies in patients with obesity who undergo such procedures. Patients can also be lost to follow-up after surgery and fail to adhere to dietary recommendations necessary to prevent such deficiencies. With the increasing popularity of bariatric surgery as a treatment for obesity, it is crucial to be aware of such complications and recognize the presenting symptoms of nutritional deficiencies so that necessary measures can be taken for prevention and treatment.

The effective and timely management of malnutrition complications following bariatric surgery necessitates the collaboration of an interprofessional healthcare team comprising various disciplines. Key healthcare providers involved in the process include dietitians, bariatric surgeons, and general practitioners, who should provide preoperative counseling and assessment to patients. Mental health professionals also play a crucial role in patient-centered education and promoting compliance with supplementation and follow-up care. Additionally, for female patients planning to undergo or who have already undergone weight loss surgeries and wish to conceive, preconception counseling by obstetricians is essential to address their specific needs. Clinicians specializing in bariatric patients should familiarize themselves with the clinical presentations of deficiencies and appropriate monitoring protocols to ensure early diagnosis. When patients present with severe complications from deficiencies such as neurological, dermatological, or hematological disorders, a careful history and an organized effort by an interprofessional team of physicians, mid-level practitioners, pharmacists, clinical dieticians, and nursing staff are critical to ensure optimal outcomes. Earlier diagnosis can improve morbidity and mortality. [Level 2]
