Obesity is a public health issue, with several factors as its cause. It may be related to several co-morbidities such as diabetes mellitus II, systemic arterial pressure, dyslipidemia, cancer and others. Current research verified aspects of bariatric surgery with special focus on alterations caused by the lack of vitamin B12. The bibliographical review evaluated scientific papers, particularly recent ones, to obtain data on the theme. Obesity is defined as a disease characterized by the accumulation of fat in the adipose tissue. Bariatric surgery helps weight loss in obese people with the consequence improvement of comorbidities and increase in life expectancy. The surgery may, however, bring about certain early or delayed problems. Nutritional deficiencies will occur in time due to low food ingestion and anatomical changes caused in the digestive system. One of the most frequent deficiencies after surgery is the lack of vitamin B12, especially in Roux´s y gastric bypass. Lack of vitamin B may cause cardiovascular diseases, neurological problems, complications in pregnancy and anemia. Nutritional follow-up after surgery is required to minimize the surge of these complications. The surgeon must inform the patient on the importance of using vitamin supplements and efficient supplementation ways for a better post-surgery performance.
