Research output: Chapter in Book/Report/Conference proceedingChapter


Hematological complications after bariatric surgery can present early on in the postoperative period most commonly as hemorrhage and venous-thrombo-embolism. Hemorrhage is a direct result from the procedure and its incidence has been going down as the procedures and surgical equipment become more efficient. Thrombosis is one of the most feared complications after surgery since it can be life-threatening. Surgery as well as obesity are risk factors for it. Long-term complications are usually related to deficiencies of either vitamins or minerals, the more malabsorptive component a surgery has, the higher the risk for this type of complication. Iron deficiency anemia is the most common one, but as we will see in the chapter, copper, vitamin K, and vitamin B12 among others can also have hematological complications.
