Dr. Ravi Kumar is a board-certified neurosurgeon who left the operating room to explore the questions that matter most about your health.
Listen to the PodcastEvery week, I cut through the noise of health headlines and marketing claims to bring you what the research actually says. No dogma, no agenda, just an honest look at the science that shapes how you live, heal, and thrive.
In a new sham-controlled trial, catheter ablation for atrial fibrillation beat a fake version of the procedure on rhythm control but not on how patients said they felt six months later.
A Danish study of 132,585 adults newly diagnosed with type 2 diabetes found that those who started a statin within the first year had a 15% lower relative risk of dementia over 10 years than those who never started one.
A 2,280-patient trial presented at ESC Congress 2026 found that giving a strong blood thinner without aspirin after a major heart attack cut serious bleeding by about a third but left more patients dead, reinfarcted or stroked at one year.
The European Society of Cardiology's 2026 heart failure guidelines, published August 28, recommend semaglutide or tirzepatide for patients with preserved ejection fraction and obesity, and erase the middle ejection fraction category that has shaped treatment decisions for years.
A 17,710-person analysis presented at ESC Congress 2026 found that the higher a person's blood level of the sweetener xylitol, the higher their rate of death, heart attack or stroke, but the sweetener was measured in blood, not in the diet.
The SINGLE-AF trial is the first randomized test of direct oral anticoagulants in atrial fibrillation patients whose stroke risk sits in the middle, a group guidelines have hedged on for years.
What if cancer is better understood as a metabolic and mitochondrial disease than a purely genetic one? Dr. Ravi Kumar sits down with Dr. Casey Peavler, a hospitalist who has spent years digging into the metabolic science of cancer, to walk through the press pulse framework: a chronic press like therapeutic ketogenic metabolic therapy and stress reduction that handicaps a tumor's fuel supply, followed by intermittent pulses like high dose IV vitamin C and hyperbaric oxygen delivered when the cancer cell is least able to defend itself. They cover why glucose and glutamine supply roughly 80% of the NADPH a cell uses for antioxidant defense, why antioxidants may help prevent cancer but appear to worsen outcomes once it is present, and how repurposed drugs like metformin, mebendazole, and ivermectin fit in. Nothing here is medical advice, and every therapy discussed is framed as a potential add-on to work through with your oncologist.

Dr. Ravi Kumar is a board-certified neurosurgeon and assistant professor of neurosurgery at the University of North Carolina. After years in the operating room, a transformative sabbatical in India changed how he saw medicine forever.
Now, through The Dr. Kumar Discovery, he explores the intersection of modern science, traditional wisdom, and the questions most doctors never think to ask.

He is the best of both worlds - he shares a wealth of modern medical knowledge, but also empowers the listeners to take personal responsibility for their health."
