When ChatGPT Became My Doctor: How AI Fixed My Intestinal Crisis

A Personal Case Study

A few months ago, I found myself doubled over with severe stomach cramps. Naturally, I turned to my primary care physician for answers. After a quick visit, I was told I needed to see a gastroenterologist—but the earliest appointment was in November, a full seven months away. It was late March, and I was in pain now. Frustrated but determined, I decided to try something unconventional: I consulted ChatGPT.


I shared every detail with ChatGPT—excruciating stomach cramps, bloating, discomfort, my hiatal hernia, a decade on Nexium for GERD, even my daily diet. After some back-and-forth, it pinpointed a condition I’d never heard of: Small Intestinal Bacterial Overgrowth (SIBO). It suggested a low FODMAP (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) diet, which cuts carbs that feed gut bacteria. I was clueless about it and devastated to learn it banned most of my favorite foods. But ChatGPT became my lifeline. Using the app on my phone, I could check any food on the spot—getting not just a yes-or-no answer but detailed explanations, including the chemistry behind it and clever alternatives. It shared recipes, like making ghee to replace butter (a SIBO trigger) and swapping garlic, my go-to, with chives. It even guided me through preparing ghee from scratch and tweaking my favorite dishes. Desperate but skeptical, I tried the diet. It even told me that I might be deficient in certain vitamins and nutrients (e.g., vitamins B12 and D, plus iron, magnesium and zinc). Within days, my symptoms vanished. I was floored—it actually worked!

But the relief was temporary. A couple of weeks later, the cramps returned. Back to ChatGPT I went, and it suggested a breath test to measure hydrogen and methane levels, which could confirm SIBO. It also explained why my symptoms might have returned: the bacterial composition in my gut was likely adapting to the new diet. When I got the test results, they showed elevated levels of both hydrogen and methane, indicating not just SIBO but also Intestinal Methanogen Overgrowth (IMO). I shared the exact test readings with ChatGPT, and it confirmed the diagnosis, breaking down each condition in simple terms.

ChatGPT became my guide. It helped me navigate which foods were safe on the low FODMAP diet, offering more recipes and substitutions. When I went to pick up my prescribed medications—neomycin for the methane-producing microbes and Rifaximin for the hydrogen-producing bacteria—I hit a snag. Rifaximin cost $700, and my insurance wouldn’t cover it. Back to ChatGPT, which explained the role of each drug and suggested a specific herbal remedy (Berberine) as a temporary substitute until I could get the Rifaximin approved (Amazon delivered the dose and brand that ChatGPT recommended within 4 hours). It was like having a doctor who never got tired of my questions, always ready with clear, actionable advice.

The Thesis: AI as the Future of Primary Care

My experience wasn’t just a one-off success—it’s a glimpse into the future of healthcare. I believe AI will become the primary medical interface for most people, acting as a tireless, infinitely patient medical expert available 24/7. Here’s why:

1. Accessibility and Speed

Unlike human doctors, who are often overbooked, not current on all illnesses, and limited by office hours, AI is always available. In my case, I didn’t have to wait seven months for a specialist. I got immediate, actionable advice that resolved my symptoms in days. For millions of people, especially those in rural areas or with limited access to healthcare, AI could bridge the gap, providing expert-level guidance without the wait.

2. Personalized, Data-Driven Care

AI can crunch massive amounts of data—your symptoms, medical history, test results, even lifestyle habits—and deliver advice tailored just for you. When I shared my SIBO test readings, ChatGPT didn’t just confirm the diagnosis; it broke down what the numbers meant and how they tied to my symptoms. I peppered it with questions about the bacteria involved, the mechanics of my prescriptions, and their side effects, and it answered with the patience of a professor. It even fine-tuned my diet based on my updates, suggesting, for instance, a baked chicken recipe with FODMAP-safe spices—like having a nutritionist in my kitchen. This kind of personal, on-demand expertise and limitless patience is impossible to get—even if you somehow have access to the very best doctors and nutritionists, given their packed schedules and differing priorities.

3. Cost-Effective Solutions

Healthcare is expensive, and insurance doesn’t always cover what you need. When I faced a $700 prescription, ChatGPT offered an affordable alternative without missing a beat. AI can help patients navigate high costs by suggesting generics, over-the-counter remedies, or lifestyle changes that are just as effective. This could save billions in healthcare spending while keeping people healthier.

4. Empowering Patients

AI doesn’t just diagnose—it educates. Every time I asked ChatGPT a question, it explained the why behind its advice. I learned about SIBO, IMO, and the science of gut bacteria in a way that made me feel in control of my health. It even taught me how to adapt my cooking, like making ghee for my SIBO-friendly meals. This empowerment is key: patients who understand their conditions are more likely to stick to treatment plans and make informed decisions.

The Role of Humans in an AI-Driven Future

Does this mean doctors will disappear? Not entirely. While AI can handle the primary care role—diagnosing, recommending treatments, and guiding patients—there will still be a need for technicians to perform tests, draw blood, or conduct imaging. Specialists, too, will likely evolve. Some specialties may be fully subsumed by AI, especially those relying heavily on pattern recognition, like radiology or dermatology. Others will become heavily augmented, with doctors using AI to enhance their decision-making. Imagine a cardiologist who consults an AI that’s analyzed millions of heart scans to catch subtle patterns no human could see.

Challenges and Considerations

Of course, there are hurdles to overcome. AI isn’t perfect—it can misinterpret data if given incomplete or incorrect information. In my case, I had to be thorough and precise when describing my symptoms. Beyond this, I double-checked ChatGPT's answers and followed up on the references that it provided. (Since ChatGPT is sometimes wrong, validation is key.) There’s also the question of regulation: how do we ensure AI systems are safe, accurate, and unbiased? And while AI can recommend tests or treatments, it can’t physically examine you or perform procedures. These limitations mean human oversight will remain critical, at least for now.

There’s also the emotional side of medicine. A human doctor can offer empathy and reassurance in ways AI can’t (yet). But for straightforward medical issues—like my SIBO diagnosis—AI’s efficiency and accessibility outweigh the need for a bedside manner.

A Vision for the Future

Imagine a world where everyone has an AI doctor in their pocket, with seamless access to their complete health records—every blood test, scan, and prescription, all integrated into a single system. You wake up with a cough, describe your symptoms, and the AI cross-references your medical history to recommend a specific over-the-counter remedy or a telehealth test kit. If a prescription is needed, the AI issues it electronically, and your local pharmacy—now acting more like a primary care hub—dispenses it, and does a final check with you, the patient, with staff trained to handle regulatory tasks like dispensing opioids or providing basic health checks.

Devices like my Oura ring and Apple Watch are already tracking my heart rate, sleep patterns, and activity levels, feeding real-time data to apps that monitor my health. In the future, these wearables could sync directly with your AI doctor, providing a constant stream of vitals—blood sugar, oxygen levels, even gut microbiome changes. The AI could detect early signs of disease, like a slight biomarker shift indicating pre-diabetes, and intervene with personalized diet tweaks (complete with recipes) or micro-doses of medication delivered via smart implants. Pharmacies might evolve into “health hubs” with AI-powered kiosks where you step in for instant diagnostics—think full-body scans or blood tests analyzed on the spot—while a human technician oversees controlled substances or provides counseling.

Looking even further, say five or more years from now, the possibilities become truly futuristic. Homes could become medically aware, with AI-integrated appliances like a smart fridge that tracks your food intake and suggests SIBO-friendly meals, or a bathroom mirror that scans your skin for early signs of melanoma. Meanwhile, at your local urgent care center, tele-surgery robots, guided by AI and overseen by remote specialists, could perform minor procedures, reducing the need for hospital visits. For mental health, AI therapists might use voice and facial analysis to detect stress or depression, offering real-time coping strategies or connecting you to a human counselor only when needed. Your AI doctor could even predict health risks years in advance by analyzing your 23-and-me genetic data alongside your wearable stats, recommending lifestyle changes before symptoms even appear.

In this future, the line between healthcare and daily life blurs. AI will react quickly to illnesses as they occur, orchestrating your wellness through constant, unobtrusive monitoring and hyper-personalized advice. Human doctors become orchestrators of complex cases, managing a 'team' of very specialized AIs working together with the human doctors. More general medical AIs will handle the routine and preventative, making healthcare truly universal. The catch? We’ll need ironclad privacy laws and robust AI ethics to ensure your data stays secure and the system doesn’t prioritize profit over care. But if we get it right, the future of health could be as effortless as asking, “Hey, AI, what’s a SIBO-safe dinner tonight?”

My experience with ChatGPT showed me this future isn’t far off. It wasn’t just a tool—it was my primary care physician, guiding me through diagnosis, treatment, recipes, and even insurance headaches. Here’s the takeaway: AI is already smart enough to help you manage your health better than the current system allows. It’s not about replacing doctors entirely—it’s about making expert care available to everyone, anytime, anywhere.

  Comparative Advantage, Tariffs, and Why I Pay My Barber I keep hearing on the news that the U.S. has a massive trade deficit. Politicians insist this is terrible for our economy. They say we need huge tariffs on imported goods, that we must manufacture everything here at home, and stop buying so much from other countries. But recently, I noticed something interesting in my own life that seems directly related: I have a massive trade deficit with my barber—and things are working out pretty well for both of us. Every few weeks, I pay my barber to cut my hair. Yet she never buys anything from me—not engineering expertise, not a mandolin lesson—nothing at all. If the government tracked my haircuts the way it measures international trade, they’d say I’m getting ripped off, and my barber is getting rich. So why don't I "protect" myself and eliminate this unfair deficit? I suppose I could start cutting my own hair. But trust me—you don't want to see the results. I’d ...

Will Tariffs Jack Up Your Bills and Push the World to the Brink?

Image
Your next Walmart run might hit hard. The U.S. has imposed 145% tariffs on Chinese goods, with China retaliating at 125%, poised to drive up costs for clothes, appliances, and more. A sudden reprieve on April 12, 2025, exempted electronics—$127 billion worth, nearly a third of Chinese imports—keeping phones and PCs affordable for now. But with most goods under heavy tariffs, and President Trump pushing hard while Xi Jinping eyes Taiwan, fears mount that this trade war could spiral. Soaring prices could squeeze American wallets dry, or worse, spark a Taiwan conflict. The bond market, now jittery at a 4.5% yield, hints at what’s coming. Could Trump’s bold moves bankrupt consumers and ignite chaos, or does he have leverage that would mean there is a smarter deal that lies ahead? What’s driving this, and what’s next for your wallet and the world? And how much leverage does Mr. Trump really have over China? How Trade Fuels Debt—and Your Costs World trade is a giant web, and the U.S. sits ...

America’s Ideological Dumpster Fire

Image
What do you think of when you see this picture?  The image serves almost as a political Rorschach test.  To one observer, the flames perhaps represents Mr. Trump setting a badly needed fire to the previous (Biden) administration and its governing approach, who were (in their view) chaotic, reckless people driven by a 'woke' ideology rather than evidence-based logic. To another, the same image  might symbolize the current government of Donald Trump and his administration—a flaming disaster characterized (in their view) by chaotic, reckless people and driven more by impulsive ideology than evidence-based logic.  These starkly different interpretations highlight a critical reality: ideology eclipses an analytical approach for determining policy in today's polarized political environment. In fact, ideology often overshadows evidence-based governance, reasoned analysis, and even our shared sense of reality. At first glance, the Trump administration’s actions since J...
