Could taking stool soft pills be the cause of anemia?

Patient: My dad (age 90) has been diagnosed with anemia. His hemaglobin is low. his iron,b12 etc. levels are fine. He takes 2 stool softener/laxitive pills every night. Could these pills possibly cause the anemia. He is weak right now but otherwise in very good health…any suggestions?

Doctor: At his age, he is probably suffering from anaemia of old age. This occurs due to poor nutrition or deficiency of iron in the diet. For now, the iron supplements (as prescribed) along with dietary intake of iron rich food (green leafy vegetables) would work well for him. In addition, you may give him a deworming (anti-helminthic) medication single dose at night, in consultation with your GP.
