Bariatric surgery for morbid obesity is rapidly gaining popularity. Restrictive and/or malabsorptive surgical interventions result in dramatic weight loss with significantly decreased obesity-related morbidity and mortality. Anemia, which may affect as many as two-thirds of these patients, is of concern and generally thought to be caused by iron deficiency. Although iron deficiency in this population may be frequent given pouch hypoacidity, defunctionalized small bowel, and red meat intolerance… 
Anemia and iron deficiency before and after bariatric surgery.
TLDR
Anemia and iron deficiency are frequent in obese patients and must be treated before and after bariatric surgery, and management of each condition must be directed at correcting the 2 major sources of iron deficiency and anemia.
Iron Deficiency and Bariatric Surgery
TLDR
The aim of this study was to review the current knowledge of nutritional deficits in obese patients and those that commonly appear after bariatric surgery, specifically iron deficiencies and their consequences and some recommendations for screening and supplementation are presented.
Iron deficiency and anaemia in bariatric surgical patients: causes, diagnosis and proper management.
TLDR
Assessment of patients scheduled for bariatric surgery should include a complete haematological and biochemical laboratory work-up, including measurement of iron stores, vitamin B12 and folate, and maintenance IV iron treatment should be provided as required, providing an excellent tool to avoid or treat iron deficiency.
Malabsorption anemia and iron supplement induced constipation in post‐Roux‐en‐Y gastric bypass (RYGB) patients
TLDR
Clinical recommendations include prophylactic iron supplementation with ferrous sulfate to prevent iron deficiency anemia and strategies for managing the side effects of iron supplementation including constipation may require a unique approach based on the anatomical and functional changes in the post‐RYGB patient and the requirement for lifelong iron supplementation.
Cooper deficiency anemia: A complication after bariatric surgery
TLDR
The hypothesis of copper deficiency was considered and a low serum level of 40μg/dl was found, and an oral supplementation with high doses of copper resulted in evident clinical and laboratorial improvements after eight weeks of therapy.
Bariatric Surgery in Adolescents: Is Routine Nutrient Supplementation Sufficient to Avoid Anemia Following Bariatric Surgery?

TLDR
Folate levels were significantly reduced following SG and were lower in SG compared with LAGB patients, which highlights the importance of ongoing surveillance by primary care providers and the need for additional folate supplementation following SG.
Prevalence of Anemia in Subjects Randomized into Roux-en-Y Gastric Bypass or Sleeve Gastrectomy
TLDR
The etiology of anemia appears to be iron-related and precipitated by the female sex, however, anemia of chronic inflammation cannot be discounted as being somewhat causal.
Hematological Variables and Iron Status in Abdominoplasty After Bariatric Surgery
TLDR
As expected, hemoglobin fell after abdominoplasty, however, after a one-third recovery of hemoglobin concentrations by week 1 postoperative, they failed to return to preoperative levels by the eighth week.
Prevalence of Anemia and Related Deficiencies 10 Years After Gastric Bypass—a Retrospective Study
TLDR
Twenty-seven percent of patients had anemia more than 10 years after RYGB, and an inverse correlation was found between anemia and regular medical checkups concerning gastric bypass surgery.
Nutritional deficiencies in obesity and after bariatric surgery.
TLDR
Current knowledge of nutritional deficits in obese and overweight individuals and those that commonly present after bariatric surgery are reviewed and current recommendations for screening and supplementation are summarized.

TLDR
Couning, monitoring, and nutrient and mineral supplementation are essential for the treatment and prevention of nutritional and metabolic complications after bariatric surgery.
Nutrient deficiencies secondary to bariatric surgery
TLDR
This review describes the literature published in the last few years concerning nutritional deficiencies after bariatric surgery as well as their etiology, incidence, treatment and prevention and gives special attention to adolescents, mainly girls at reproductive age who have a substantial risk of developing iron deficiency.
Micronutrient deficiencies after gastric bypass for morbid obesity.
TLDR
Previous reports of thiamine deficiency-related neurologic sequelae, immune paralysis, and marrow suppression, together with the micronutrient deficiencies and anemia herein reported make long-term frequent metabolic assessment of these patients essential.

Prospective Hematologic Evaluation of Gastric Exclusion Surgery for Morbid Obesity
TLDR
All gastric exclusion patients should, as a minimum, be placed on oral multivitamin preparations containing iron, folate and vitamin B12, and it is imperative that these patients be followed closely for the remainder of their lives with appropriate studies and replacement as necessary.
Iron Absorption and Therapy after Gastric Bypass
TLDR
This study suggests but does not prove that the addition of vitamin C to iron therapy after gastric bypass is more effective in restoring ferritin and hemoglobin than iron alone.

TLDR
Most diet-related surgical complications can be prevented by adhering to strict eating behavior guidelines and supplement prescriptions, and frequent monitoring of nutrition status for all patients can aid in preventing severe clinical deficiencies.
Evidence for the Necessity to Systematically Assess Micronutrient Status Prior to Bariatric Surgery
TLDR
Data indicate a high prevalence of micronutrient deficiencies in morbidly obese subjects, and strongly recommend a systematic assessment of the micronsutrient status in all candidates for bariatric surgery.
Preoperative nutritional status of patients undergoing Roux-en-Y gastric bypass for morbid obesity
Few data exist concerning preoperative nutritional status in patients undergoing bariatric surgery. We retrospectively analyzed the preoperative values of serum albumin, calcium, 25-OH vitamin D,
Late effects of gastric bypass for obesity.
TLDR
The procedure was well received by patients and most achieved adequate weight loss, but most subjects consumed inadequate diets and many developed iron and/or vitamin B12 deficiencies, and some also developed abnormal laboratory tests suggesting coexisting osteomalacia.
