Welcome to The Dr. Kumar Discovery, a health and wellness podcast hosted by Dr. Ravi Kumar, a board-certified neurosurgeon. This is the medical podcast for anyone who wants honest, evidence-based answers to the health questions that matter most. No corporate influence. Just a physician who reads the research, questions the dogma, and breaks it down in plain language so you can make better decisions about your own health.
Dr. Kumar is a practicing neurosurgeon who brings a surgeon's precision to topics most doctor podcasts only scratch the surface of. Each episode dives deep into the science behind metabolic health, cardiovascular disease, heart disease, hormones, nutrition, brain health, mental health, pain, inflammation, weight loss, aging, blood pressure, sleep, and longevity. Whether it's the truth about seed oils, the real data on GLP-1 drugs and weight loss, the science of cold water therapy, how light can heal the body, or why your testosterone is declining, Dr. Kumar goes straight to the peer-reviewed literature and tells you what the evidence actually shows, not what the headlines say. This is evidence-based medicine in plain English.
The show features three formats. Solo deep dives explore a single health topic from the ground up, covering everything from the biology to the practical takeaways you can use today. Expert interviews bring on leading researchers, clinicians, and forward-thinking voices in health and medicine for in-depth conversations you won't hear anywhere else. The Tribulations series tells the true stories behind medicine's greatest breakthroughs, from the discovery of penicillin to the invention of vaccines to a father's fight to save his son's life. These are the stories of the doctors, scientists, and patients who changed the course of medicine.
Topics covered on the show include testosterone and hormone optimization, sleep science, photobiomodulation and red light therapy, exercise with oxygen therapy, creatine, uric acid and gout prevention, gut health and probiotics, cardiovascular risk and Lp(a), cholesterol, PANDAS in children, PTSD and trauma, acetaminophen safety, glyphosate, foot health, and much more.
If you're tired of generic health advice and want to hear from a neurosurgeon who actually reads the studies, The Dr. Kumar Discovery is your podcast. New episodes drop regularly. Subscribe and join the discovery.

Have you ever heard of a lipoprotein called lipoprotein little a or LP little a? If you're like most people, the answer is no, never. It's not on the standard lipid panel, and you have to ask for it specifically. And yet, roughly one in four adults globally have levels high enough to roughly double their lifetime risk of heart attacks and strokes. And most of these people have no idea.
Ravi Kumar MD:I'm doctor Ravi Kumar, and tomorrow on the Doctor. Discovery podcast, I'm doing a deep dive on LP little a, the most underdiagnosed cardiovascular risk factor in medicine, and I have a personal stake in this. My own LP little a is elevated, but the story is not all doom and gloom. If you live the right way, LP little a can actually become a superpower. Here's some important information that I can give you right now.
Ravi Kumar MD:Lipoprotein little a or LP little a is a modified LDL particle. It carries cholesterol like regular LDL does, but it has an extra protein attached to it that gives it two unique properties. First, it almost perfectly mimics a clot dissolving protein called plasminogen, which means it slows down clot breakdown and helps wounds seal faster. Second, it's a magnet for oxidized fats in your bloodstream. Those two features made it incredibly useful in the ancestral world, where bleeding out from childbirth, animal attacks, and bowel wounds were the leading cause of death.
Ravi Kumar MD:People with high LP survived. That's why the gene is still here. Now here's the part that most doctors never tell you. Your LP little a number, if it's high, is not a cardiovascular disease sentence. Your LP little a level is mostly locked in by your DNA.
Ravi Kumar MD:It's somewhere between 70 to 90% genetic. And diet and exercise basically don't move it. But LP little a only causes harm under two specific conditions. One, where your blood vessel walls are being chronically injured by things like hypertension, metabolic disease, or smoking, or two, when your LP little a particles are loaded with oxidized fats, which in most of us would be from industrial seed oils. So tomorrow's full episode will go much deeper.
Ravi Kumar MD:We'll discuss the specific evolutionary reason why LP little a gene still exists in the first place. We'll talk about why women have higher levels than men and why menopause actually makes it worse. We'll discuss the ethnic patterns that mean my South Asian ancestry and any of you with African ancestry are usually running higher on your LP number. We'll talk about the new RNA based drugs in late stage trials that can slash LP levels by more than 90%, and we'll talk about the simple framework I'm using personally to make sure my own elevated LP levels stays a non issue for the rest of my life. So if you've been told that you have high LP little a levels, or if a parent or a sibling had an early heart attack, or if you've been doing everything right and your cholesterol numbers still aren't where they should be, this conversation will shift how you think about all of it.
Ravi Kumar MD:Full episode drops tomorrow, or if you're listening to this later, just look for the next episode. And in the meantime, ask your doctor to check your LP level at your next visit. It just needs to be checked one time in your entire life, and you'll know where you stand. We'll talk tomorrow. Cheers.
