Hello, Your symptoms are suggestive of APD or acid peptic disorder. The cause for this condition can be understood only after investigations like gastric endoscopy, an abdominal sonogram and colonoscopy. Your bleeding disorder may or may not be related and hormone profile may need to be done if no other cause has been found to answer the bleeding pattern. The low iron count is a result of the persistent bleeding and inability to eat and you should manage this with oral or parenteral iron supplements. Wish you speedy recovery.
