Consult your GI/Diet: Iro Def, B12 def and Thiamine def develop over time post Bariatic surgery and may cause severe fatigue/tiredness.After bariatric surgery you may experience reactive hypoglycemia:This may happen after eating foods high in sugar or simple carbohydrates. It is thought to be related to dumping syndrome. Instead of sugars and simple carbohydrates, eat complex carbohydrates , they release less sugar.
