Abstract

Background: Obesity is a serious health problem with increasing incidence. worldwide and remains one of the most important causes of preventable deaths. We aimed to examine the relationship between Vitamin B12 and Folic acid, which have an important role for human life, and homocysteine is widely recognized for its association with the development of cardiovascular disease, although its role as an independent risk factor remains a topic of ongoing debate.

Materials and methods: We evaluated 126 patients who underwent bariatric metabolic surgery between September 2019-September 2020. In addition to demographic characteristics of the patients, weight, Vitamin B12, folate, HbA1c, cholesterol, triglyceride, ferritin, serum iron, albumin levels at preoperative, postoperative 1st month, 6th month, 12th month follow-ups were analyzed.

Results: Patients with the desired biochemical parameters at the determined follow-up points were identified and two groups were formed as RYGB(n = 43) and SG(n = 7) patients. When biochemical parameters were analyzed between the groups, homocysteine, HbA1c, HDL Cholesterol, VLDL Cholesterol, Total Cholesterol, Triglycerides, Ferritin, Serum Iron levels showed a statistical difference (p < 0.001). Folate (p = 0.064) and albumin (p = 0.257) did not show a significant difference over time. The change in vitamin B12 (p = 0.409) over time was not significant in the SG group, whereas a significant difference was observed in the RYGB group (p < 0.001). When we established a marginal model to determine the factors affecting the change in homocysteine over time, vitamin B12 and folate values.

Conclusions: The relationship between Vitamin B12, folate and homocysteine is important in order to better understand the complications that develop in bariatric metabolic surgery patients, to prevent possible complications and to better manage the process.

Keywords: Bariatric metabolic surgery; Cardiovascular disease; Folate; Homocysteine; Vitamin B12.
