Vitamin K and other markers of micronutrient status in morbidly obese patients before bariatric surgery

Abstract

Micronutrient status shows differing relationships with age, gender and BMI. Vitamin K insufficiency was present in 40% and not related to deficiencies in other vitamins or micronutrients. Vitamin D and vitamin K supplementation should be considered prebariatric surgery in patients with diabetes or severe insulin resistance.

Micronutrient Deficiencies in Morbidly Obese Women Prior to Bariatric Surgery

“…Interestingly, the iron deficiency and anemia rates found in our study are considerably lower than those reported by studies carried out in other countries [10,11,13,33,37,40]. Low plasma iron concentrations found in our study are consistent with the low iron intake reported in the FFQ, as well as with the fact that the patients were mainly young women in reproductive age.…”

“…However, such procedure carries the risk of complications, such as deficiencies for micronutrients, even when supplements are used [13,[28][29][30][31][32]. Moreover, obese patient often present with micronutrient deficiencies before to bariatric surgery [9][10][11][12][13][33][34][35][36][37][38][39][40].…”

“…Data regarding nutritional indicators for obese patients seeking bariatric surgery are scarce; however, some authors have noted low pre-surgical plasma concentrations of iron, hemoglobin, ferritin, zinc, folic acid, vitamin B 12 , 25(OH)D, calcium, among others. (Table 5) [9][10][11][12][13][33][34][35][36][37][38][39][40].…”

“…It is important to note that adequate vitamin B 12 stores in the human body can maintain stable plasma levels of this vitamin for long periods of time; therefore, a plasma vitamin B 12 deficiency suggests low intake over a prolonged period of foods such as fish, shellfish, meat, dairy products, and multivitamins or, at a lower rate, malabsorption of vitamin B 12 due to intrinsic factor deficiency. In terms of vitamin D status, measured as plasma 25(OH)D, 71.7 % of the patients Papamargaritis et al [38] Gobato et al [39] Ewang-Emukowhate et al [40] Damms-Machado et al [13] Moize et al [11] de Luis et al [12] Schweiger et al [10] Ernst [36] Toh et al [9] Flancbaum [33] Gender MCV mean corpuscular volume, NM not measured, NA not available, F female, M male evaluated showed insufficiency and deficiency. 25(OH)D deficiency in the obese population has been described in many studies, with a reported inverse correlation between BMI and 25(OH)D plasma concentration.…”

Preoperative nutritional management of bariatric patients in Australia: The current practice of dietitians

“…[8][9][10][11] Nutritional deficiencies are commonly seen in patients presenting for bariatric surgery. 7,[12][13][14][15][16] Pre-existing micronutrient deficiencies prior to bariatric surgery, can involve poorer prognosis and postoperative complications. 13,15,16 Therefore, it is essential to screen and correct any abnormalities prior to surgery.…”
