Hi and welcome to the forum! I am glad that I can help you.
You want to know whether there could be any underlying condition that could be related to anemia.
Anemia may appear due to several reasons including lack of iron, proteins, increased blood loss (due to bleeding out or hemolysis). An increased number of reticulocytes (immature red blood cells) indicate that the bone marrow functions normally and tends to make up for the loss of red blood cells and correct the anemia. However, anemia can be an additional symptom of underlying cancer in the body. If there is no particular reason for the anemia and the condition doesn't improve despite taking iron substituents or blood transfusions, there might be an underlying neoplastic process in the body.
Given the data that you described, it seems probable that you experience anemia. Have your coagulation status checked. You should also consider having your stool checked for possible hidden bleeding, which may be due to chronic intestinal conditions or colon cancer. You may also need to have a bronchoscopy to rule out bronchial cancer which is characterized with coughing and hemoptysis (coughing up of blood or mucus that contains blood). You may need to have an RTG scan of the ribcage and antibacterial culture to rule out possible tuberculosis which is also characterized with hemoptysis.
