Presence of Serum Ferritin before and after Bariatric Surgery: Analysis in Dentate and Edentulous Patients

Abstract

Society has changed its own lifestyle, specially its eating habits and physical activities, leading to excessive weight and a sedentary behavior, which has contributed to obesity increase. Bariatric surgery is the most effective treatment to obesity, allowing weight loss and its maintenance. However, it has been related high levels of iron deficiency after surgery. A person’s nutritional status might be affected by total or partial tooth loss. The aim of this longitudinal prospective cohort study was to evaluate the levels of serum ferritin before and after bariatric surgery and to identify if there is a relation with tooth loss. The sample was composed of 50 patients selected and assisted at Amaral Carvalho Hospital, located in Jaú city, Brazil. The use and necessity of prosthesis, dental absence or presence, and serum ferritin dosage were evaluated. Student’s t test, Univariate analysis, Chi-square and Odds Ratio were adopted (p<0.05). There was no significant difference regarding the serum ferritin levels between dentate and edentulous patients prior to surgery (p = 0.436). After surgery, the serum ferritin levels were higher in edentulous patients (prosthesis users) when compared to the pre-surgical levels, and the post-surgical levels presented significant difference regarding the dentate patients (p = 0.024). It can be concluded that rehabilitated patients in postoperative period showed better levels of serum ferritin after surgical intervention.

Evaluation of systemic conditions, tooth loss, body image, and quality of life of women with obesity and women who underwent gastric bypass surgery

“…In this study, a higher prevalence of hypertension was observed in patients with obesity ( P = .020) (Table 1). Hypertension was the most important risk factor for cardiovascular disease, being more common than smoking, dyslipidemia, and diabetes 2,18,19 …”

“…Patients with obesity have a reduced immune response considering the widespread inflammatory state of the body caused by inflammatory cytokines and adipokines, including tumor necrosis factor alpha (TNF‐α), Interleukin‐6 (IL‐6), adiponectin, leptin, adipocytokine, and cytoplasmic enzymes 1 . These patients may present several comorbidities, such as hypertension, dyslipidemia, type II diabetes mellitus, and obstructive sleep apnea 2 . Furthermore, obesity has been associated with several oral changes, including reduced salivary flow, periodontal diseases, and tooth loss 3 …”

“…such as hypertension, dyslipidemia, type II diabetes mellitus, and obstructive sleep apnea. 2 Furthermore, obesity has been associated with several oral changes, including reduced salivary flow, periodontal diseases, and tooth loss. 3 Periodontitis is a disease in which the toxins produced by the bacteria stimulate a chronic inflammatory response that destroys the periodontal tissue, causing tooth mobility that may progress to tooth loss.…”

Condição periodontal e hipertensão arterial em pacientes obesos mórbidos antes e após a cirurgia bariátrica: estudo de coorte prospectivo

“…O estado nutricional de um individuo pode ser afetado pela perda total ou parcial dos dentes. Foratori et al, 2016 avaliaram os níveis de ferritina sérica antes e apos a cirurgia bariátrica e obtiveram como resultado que após a cirurgia, os níveis de ferritina sérica foram maiores em pacientes edêntulos quando comparados com os pacientes pré-cirurgia bariátrica.…”

“…Fato este, que deveria contribuir para a redução da periodontite, o que não ocorre. Tendo em vista o aumento no número de P. gingivalis e do sangramento periodontal (SALES-PERES et al, 2016), após a cirurgia bariátrica.…”
