In this episode of Dr Tisdall Unfiltered, I explain how I approach teaching medical students to connect the basic medical sciences with clinical reasoning and patient care. I’m Dr. Philip Tisdall, a physician who practiced general pathology for decades before moving into medical education. My experience working through patient problems with clinicians shapes how I teach: every concept needs a purpose, and that purpose is helping you understand, diagnose, and treat your patients. I walk through the framework I use in my textbook, Clinical Pathophysiology: begin with the patient’s clinical presentation, build an understanding of normal structure and function, explore what happens when the organ fails, and then move into specific disease groups. Using examples from heart disease, I explain how symptoms such as shortness of breath and edema give anatomy and physiology a meaningful clinical context. We also explore why being an expert doesn’t automatically make someone an effective teacher, how unfamiliar medical vocabulary can interrupt understanding, and why preparing students for patient care requires more than delivering information. I explain how I judge my own teaching by whether students can apply what they’ve learned. From there, I discuss why neurology and endocrinology require different approaches. I share how I want to connect neuroanatomy more closely with the physical examination and imaging, and how looking at an organ’s evolutionary history helps me frame questions about its function. Thyroid physiology provides an example of connecting development, metabolism, temperature regulation, and clinical symptoms. If you’re a medical student trying to organize a new system, connect concepts across courses, or move beyond memorizing isolated facts, this episode offers a practical starting point. My goal is to help you build a foundation you can use when a patient walks through the door.

    Why Passing Medical School Exams Isn’t Enough: Building Clinical Reasoning

    Interested in joining my community for FREE? I’m now offering a free week trial for Medical School Companion. Inside the community, you’ll find weekly live teaching sessions with me as well as practice questions, video courses, and more: https://www.drphiliptisdall.com/?utm_medium=social&utm_source=spotify&utm_campaign=spotify_description What separates passing a medical school exam from understanding the patient in front of you? As a pathologist and medical educator, I’ve spent decades learning how much more there is to medicine than knowing the right answer. In this episode of Dr. Tisdall Unfiltered, I explore how clinical mentorship, thoughtful questioning, and a structured understanding of pathophysiology help turn memorized facts into clinical reasoning. I begin with a conversation I had with a former student during his clinical clerkship about an ovarian cystic teratoma, also called a dermoid cyst. What started as a discussion about one diagnosis became an opportunity to explore medical terminology, tissue origins, and the Rokitansky nodule. I explain how a tutor can help you make connections that reading alone may leave unexplored—and why arriving with questions is part of learning medicine. I also share my experience with oral examinations and why being questioned about what you don’t know can feel uncomfortable even when you’re doing well. Learning to work with people who know more than you is an essential part of medical training, and embarrassment shouldn’t keep you from seeking guidance. Then I walk through diabetic ketoacidosis (DKA), connecting insulin deficiency and counterregulatory hormones to changes in the liver, muscle, and fat cells. I trace how impaired glucose uptake, glycogenolysis, gluconeogenesis, and ketone production fit together to explain hyperglycemia, dehydration, and acidosis. My goal is to give you a structure for understanding disease mechanisms and connecting them to a patient’s symptoms, signs, and laboratory findings. Whether you’re studying for medical school exams, entering clinical rotations, or strengthening your approach to patient care, I want you to ask more than “Do I know this fact?” Ask yourself, “Can I explain how it all fits together?” Follow Dr. Tisdall Unfiltered on Spotify or Apple Podcasts for more expert interviews and conversations about medical education, clinical reasoning, and the practice of medicine.

    Why Studying Isn’t the Same as Learning Medicine | Dr. Philip Tisdall

    Are you learning medicine—or becoming comfortable with material you still can’t explain? In this episode of Dr. Tisdall Unfiltered, I draw on my experience as a pathologist and medical educator to explain why hours of lectures, highlighting, and strong exam scores don’t necessarily translate into clinical understanding. Learning hurts. Knowing is fun. The challenge is making your study time build knowledge you can actually use. I explain how active learning connects anatomy, physiology, and pathology to clinical reasoning. My approach starts with a patient’s chief complaint and builds toward an explanation of disease: what changed, why it changed, and how those changes produce symptoms, signs, and test findings. Drawing the relevant structures and explaining their function helps reveal gaps that passive review can leave hidden. Using diabetic kidney disease as a worked example, I explore renal anatomy, kidney blood supply, nephron function, sodium-glucose transport, and diabetic hyperfiltration. I connect these mechanisms to the kidney-protective effects of SGLT2 inhibitors, showing how understanding pathophysiology makes pharmacology more logical and memorable. I also share how to put this approach into practice: study with pencil and paper, redraw foundational diagrams until you can reproduce and explain them, get expert feedback on conceptual errors, and reinforce your understanding by teaching someone else. For medical students preparing for USMLE Step 1 or struggling to connect the basic sciences to patient care, this episode offers a practical way to build a stronger foundation for thinking like a doctor.

    Medical School Admissions: What Makes a Good Doctor?

    Can a medical school interview really predict who will become a good doctor? In this episode of Dr Tisdall Unfiltered, I draw on my decades as a physician, medical educator, and former admissions committee chair to question what medical schools are selecting students for—and why applicants feel pressured to pretend they’re perfect. I discuss medical school admissions, standardized interviews, and what teaching at Caribbean medical schools taught me about academic readiness and second chances. I also examine compassion, competence, professionalism, and confidence: qualities that sound straightforward until we try to define what they mean in patient care. Through stories from my training and pathology practice, I explore how medicine tests our ability to handle stress, recognize our limits, and make decisions under uncertainty. I share the three questions I would ask when selecting medical students: Would I want you as my student, my doctor, and my partner? If you’re a premed student preparing applications or interviews, this conversation offers an experienced physician’s perspective on the admissions process and finding your place in medicine.

    Stop Memorizing Everything: How Medical Students Should Actually Learn

    Medical students are asked to learn an extraordinary amount of information—but how much of it actually matters when you are standing in front of a patient? In this episode of Dr. Tisdall Unfiltered, I take on one of the biggest problems in medical education: the “data dump.” Too often, students are handed enormous volumes of basic science information and expected to memorize it without ever being shown why it matters clinically. The result is predictable: anxiety, information overload, short-term memorization, and knowledge that disappears before students ever have the chance to use it. I explain why I believe medical students need to distinguish between what is testable and what is important for understanding patients. Those are not always the same thing. Using examples from biochemistry, gluconeogenesis, diabetes, alcohol metabolism, pharmacology, pathology, and clinical cases, I show how seemingly abstract basic science becomes valuable when it is connected directly to diagnosis, treatment, and patient care. This is the basis of what I call “Make Me Care”: if I am teaching you something, I should be able to explain why a future doctor needs to know it. I also discuss one of the most difficult skills in medical education—knowing how much to teach. My approach is “just enough, just in time.” Teaching more information does not necessarily produce more understanding. If students are overwhelmed with material before they have a clinical framework for it, they may memorize it temporarily, but much of it will be gone by the time they actually need it. That is one reason I increasingly teach medicine through clinical cases. Starting with the patient gives students a reason to care about respiratory rate, oxygen saturation, enzymes, molecular pathways, pharmacology, and pathology. Instead of learning disconnected facts and hoping they eventually fit together, we can start with the clinical problem and work backward—from patient to organ, cell, ultrastructure, protein, and molecular mechanism. I also address an uncomfortable reality for medical students: sometimes you really do have to study in two different ways. You may need to learn the material your individual school expects for a local exam while simultaneously developing the patient-centered clinical reasoning you will need for national exams, clerkships, and ultimately clinical practice. Understanding that distinction can make an overwhelming curriculum much easier to navigate. If you are a medical student trying to figure out what actually deserves your limited time and attention, this episode is about learning medicine with a purpose: not simply remembering more information, but understanding enough of the right information to take care of patients.

    How to Study Medicine Without Memorizing Everything: Clinical Reasoning, Exams & Anki

    In this episode of Dr Tisdall Unfiltered, I’m sharing a crossover conversation with the Do It Right Podcast, where I sit down with Joshua Leake, co-president of the podcast, along with his classmates Elena and Patricia from William Carey College of Osteopathic Medicine. They bring me the questions medical students are actually wrestling with: how to manage the sheer volume of information in medical school, how to know what matters, and how to move beyond studying for the next exam toward learning medicine in a way that will ultimately help you take care of patients.  One of the biggest mistakes I see in medical education is treating the problem as though students simply need to memorize more. I don’t think the issue is how much information you have; it’s how well that information is organized. In this conversation, I explain why I start with patient care and clinical-pathological correlation, and why medical knowledge becomes far easier to understand and retrieve when you have a clinical framework in which to put it.  We talk about the major transition that happens as medical students move deeper into their training: the study methods that got you this far may no longer be enough. At some point, every piece of information needs to be challenged with a much more important question: Where do I need this in patient care? You still have local medical school exams to pass, but learning for an exam and learning to practice medicine are not always the same thing.  We also get into clinical knowledge versus test-taking ability, how to approach medical school exams and national board preparation, what students really need from microbiology and pharmacology, and how to decide which details deserve your limited time and attention. We discuss the difference between knowing isolated facts and being able to reason through a patient, why understanding pathophysiology gives medical knowledge structure, and what it actually means to begin thinking like a doctor. And yes, we tackle Anki. I discuss where spaced-repetition tools can be useful, where I think they can become limiting, and what happens when a student can recognize information on a flashcard but cannot reconstruct the underlying physiology or anatomy without it. The question is not whether Anki is “good” or “bad.” The more important question is what role memorization should play in a medical education built around understanding, clinical reasoning, and patient care.  If you’re a medical student trying to figure out how to study more effectively, prepare for exams without drowning in low-yield detail, retain what you learn, improve your clinical reasoning, or make the transition from memorizing medicine to actually understanding it, this episode is for you.

    She Went Blind During the MCAT | Shrena Punj on Vasculitis, Medical School & Learning Medicine

    In this episode of Dr. Tisdall Unfiltered, I sit down with first-year MD student Shrena Punj to talk about medical school, clinical reasoning, and what it means to study medicine while living with serious chronic illness. Shrena has been diagnosed with both GPA vasculitis and Takayasu arteritis, giving her an unusual perspective as both a patient and a future physician. We discuss the overwhelming volume of first-year medical education, Anki, learning by drawing, why understanding pathophysiology matters more than memorizing facts, and how her own disease has shaped the way she thinks about medicine. Shrena also shares the extraordinary story of losing vision in one eye during the MCAT and continuing the exam. If you’re a medical student, pre-med, physician, or interested in vasculitis, autoimmune disease, clinical reasoning, or medical education, this episode offers a candid look at learning medicine from both sides of the exam room.

    Testing Teaches Pathophysiology: Why Medical Tests Matter

    If you understand why a medical test works, you understand something fundamental about the disease you’re testing for. In this episode of Dr. Tisdall Unfiltered, I explore one of the most useful ways I know to learn medicine: using diagnostic testing to teach pathophysiology. Rather than memorizing that a particular test “goes with” a particular disease, I want you to ask: What is this test actually measuring, and why does the disease make it change? I start with myocardial ischemia and troponins. Every medical student knows troponin matters in chest pain, but understanding why requires following the process from myocardial cell injury and membrane disruption to the release of intracellular contents and their appearance in the bloodstream. Once you can explain that sequence, the test becomes part of the disease story rather than an isolated fact. From there, I trace the evolution of heart failure testing—from the physical exam and chest X-ray through ECGs, catheterization, echocardiography, Doppler echo, BNP, strain imaging, and cardiac MRI. The disease did not keep changing; our ability to see and measure it did. We moved from thinking primarily about congestion, to pump function and ejection fraction, to myocyte stress, fibrosis, and infiltrative disease. That evolution matters because better tests do more than confirm a diagnosis. They can actually change how we understand pathophysiology. I also discuss the difference between structure and function. Structural and functional tests can examine the same disease from different directions and sometimes disagree. I use examples from coronary disease, renal artery disease, and COPD to show why understanding what a test measures is often more important than simply knowing when to order it. This is the kind of clinical reasoning I want medical students to develop: don’t just memorize the test. Ask what part of the disease process it reveals, whether that is structure, function, flow, pressure, cellular injury, or stress.
