Thank you for your query.
Two issues need to be addressed in your father's case:
1. Breathing difficulty while having meals means that his cardiac function needs to be re-evaluated.
needs to be corrected. This shall control the anal fissure
that has caused the bleeding. In case the bleeding does not stop then a stool routine examination and an anal examination needs to be done. I hope I have answered your query to your satisfaction.
Wishing your father all the best.
