Most students learn cystic fibrosis as a collection of facts: CFTR mutations, thick mucus, lung infections, pancreatic insufficiency. The problem is that memorizing facts rarely helps you understand why the disease behaves the way it does.
In this video, I walk through cystic fibrosis from first principles and show how a single protein defect can create a cascade of physiological changes throughout the body. By understanding the underlying pathophysiology, you'll not only understand cystic fibrosis better, but you'll also strengthen the clinical reasoning skills needed to tackle virtually any disease process in medicine.
If you've ever felt overwhelmed trying to memorize endless details for medical school, this lesson will show you a different approach—one focused on understanding rather than memorization.

Modern medical students are studying harder than ever… so why do so many still feel lost?
In this episode of Dr. Tisdall Unfiltered, I break down one of the biggest failures in modern medical education: students are being taught disconnected facts instead of learning medicine as a complete clinical story. We discuss why memorization fails, why learning objectives and compliance-driven testing often work against true understanding, and why so many students struggle with retention, anxiety, and burnout despite putting in enormous effort.
I also explain the difference between cadaver anatomy and clinically usable anatomy, why students forget diseases like atherosclerosis even after “learning” them, and how patient-centered learning changes the entire way you think through medicine. If you are a medical student, premed, resident, educator, or healthcare professional trying to improve your clinical reasoning and actually understand disease processes, this conversation is for you.
