During post-surgical check-ups of transit bipartition patients, it was observed that long-term iron requirement was not seen in any patients as a post-surgical defect except thalassemia carriers. Hence, it is proven that transit bipartition is the ideal surgery who wishes to carry on with a weight loss surgery but has mild anaemia either as a traitor as a disease. While on the other hand, both Gastric Sleeve and Gastric Bypass patients are meant to have B12 intakes after their surgeries regardless of them having low Haemoglobin levels or not.
