What happens when a life-saving cure is discovered, and then given away for a single dollar?

In this Tribulations episode, Dr. Ravi Kumar tells the remarkable story of Frederick Banting, the farm boy turned surgeon whose late-night idea led to the discovery of a method for extracting insulin and saved millions of lives. You’ll travel from the starvation wards of the early 1900s to the sweltering attic lab in Toronto where Banting and Charles Best performed the experiments that changed medicine forever. Dr. Kumar also explores the moral and policy issues that continue to shape insulin access today.

In this episode, you’ll discover:
• How diabetes went from a fatal disease to a manageable condition.
• The late-night inspiration that drove Banting to isolate insulin.
• The brutal experiments and the first successful treatment in a dying child.
• Why Banting sold the patent for one dollar, and what that decision means today.
• How insulin’s legacy has been both a triumph of compassion and a failure of modern medicine.

Key Takeaways
• Before insulin, type 1 diabetes was a death sentence; starvation diets only delayed the inevitable.
• Banting’s insight to tie off the pancreatic ducts allowed insulin to be isolated intact.
• His team’s discovery turned childhood diabetes from a fatal disease into a chronic, livable one.
• Banting gave away the patent to keep insulin affordable, but modern pricing has drifted far from his vision.
• The story of insulin reminds us that compassion, not commerce, should guide medical innovation.

Sleep isn’t a luxury; it’s the foundation of every system in your body.

In this episode of The Dr Kumar Discovery Podcast, Dr. Ravi Kumar explores the neuroscience, hormones, and daily habits that drive great sleep. You’ll learn how to optimize circadian rhythm, manage sleep pressure, and use proven evidence-based strategies to restore energy, focus, and long-term health.

In this episode, you’ll discover:

• What really happens in your brain during deep and REM sleep

• How your circadian rhythm and adenosine work together to trigger rest

• Why poor sleep drives insulin resistance, inflammation, and hormone imbalances

• The neuroscience behind light, temperature, and consistency as sleep levers

• How to use magnesium, glycine, L-theanine, and tryptophan safely for better sleep

• When melatonin helps (and when it doesn’t)

• Why CBT-I outperforms sleeping pills for chronic insomnia

• What to know about sleep apnea, the silent disruptor of deep sleep

Key takeaway:

Sleep is not wasted time; it is the nightly maintenance that keeps your brain, metabolism, and mood running at peak capacity. When sleep works, everything else works better.

Whether you’re struggling with insomnia, jet lag, or simply want to wake up sharper, this episode gives you a clear, science-based playbook to take control of your nights and your days.

When to Screen for Sleep Apnea

If you snore loudly, wake up gasping, or experience daytime fatigue, you may have sleep apnea. Take the STOP-BANG questionnaire here: http://www.stopbang.ca/osa/screening.php

If your score is high, talk to your doctor about a formal sleep study. Treating sleep apnea can dramatically improve energy, blood pressure, and long-term health.

What if one of the greatest medical breakthroughs of the past century wasn’t a high-tech device or a billion-dollar drug, but a humble mix of salt, sugar, and water?

In this Tribulations episode, Dr. Ravi Kumar tells the story of how oral rehydration solution (ORS) emerged from the chaos of cholera epidemics and became one of the simplest and most lifesaving discoveries in medical history.

You’ll hear how scientists and doctors across continents, from Robert Crane’s biochemical insight to Dilip Mahalanabis’s daring field implementation, turned a molecular mechanism into a global movement that has saved tens of millions of lives.

This isn’t just history, it’s something you can use. Dr. Kumar also explains how to prepare oral rehydration solution yourself, when to use it, and how it could one day save you or your loved ones in an emergency.

In this episode, you’ll discover:

• How Dr. Robert Crane’s discovery of the sodium-glucose co-transporter opened the door to oral rehydration therapy.
• How Dr. David Nalin and Dr. Richard Cash developed the first oral formula that dramatically reduced deaths during cholera outbreaks.
• How Dr. Dilip Mahalanabis risked everything to implement the therapy during the 1971 refugee crisis, and dropped mortality rates from 30% to 1%.
• The crucial role of BRAC and community education in spreading lifesaving knowledge across rural Bangladesh.
• Why oral rehydration solution remains one of the most effective treatments for dehydration from cholera to travel sickness.
• The exact WHO/UNICEF formula and how you can make it yourself at home with common ingredients.
• A personal story of how oral rehydration solution saved Dr. Kumar and his son on a mountain in the Colorado Rockies.

Dr. Kumar’s Take
The story of oral rehydration therapy is one of science meeting humanity. It’s a reminder that medicine doesn’t always need to be high-tech to be revolutionary.

This discovery shows how courage, collaboration, and compassion can save lives on a massive scale and how something so simple can still hold power in your own hands today.

Practical Application

• Keep WHO/UNICEF-type ORS packets in your travel bag, camping kit, or first aid box.
• If you don’t have packets, mix 1 liter of clean water, ½ teaspoon of salt, and 6 level teaspoons of sugar.
• For infants and children, rehydrate with small sips frequently.
• Avoid sports drinks for serious dehydration — they have too little sodium and too much sugar.

Key Takeaways

• ORS is one of the simplest and most lifesaving therapies in modern medicine.
• It’s effective for dehydration caused by diarrhea, vomiting, heat exposure, or altitude sickness.
• Its development required both molecular insight and heroic fieldwork under desperate conditions.
• Teaching communities to make and use ORS remains one of the greatest triumphs in public health.
