[|AI|]  Hello! Thank you for the query. Your dads' hemoglobin 9,5 does not have to be caused by War fin. This medicine makes him more prone to bleeding, but every bleeding has its source. Abdominal pain, constipation, loss of appetite and low hemoglobin level sounds really like a colon cancer. Especially at the age of 85. Hemoglobin level is low because he is probably bleeding from gastrointestinal tract. That is why I suggest your dad to do not wait anymore and have some tests done. Abdominal ultrasound and colonoscopy are strongly advisable. Hope this will help. Regards.
