Explain Any Diagnosis in Plain Language with Teach-Back Checks

I need to explain [diagnosis] to a patient who has [low/moderate/high] health literacy. The patient is [age] years old and [relevant context: newly diagnosed, managing chronic condition, caregiver of the patient is the audience]. Write an explanation that covers: what the condition is in simple terms, what caused it or what the risk factors are, what symptoms to watch for, what the treatment plan involves and why, what happens if left untreated, and what the patient can do at home to manage it. Use the teach-back method by including 2-3 questions I can ask the patient to verify understanding.
