    Think of your gut after a bad flare, food poisonin Think of your gut after a bad flare, food poisoning, or a course of antibiotics like a city after a flood.

The water goes down. The inflammation clears. But the roads have cracks and potholes, and traffic never flows quite the same way afterwards.

That used to just be a metaphor. Now a new paper gives us a piece of the biology underneath it. The condition is real — gastroenterologists call it post-inflammatory (or post-infectious) IBS — and we’ve been studying it for years. What this paper adds is one specific thread: how inflammation leaves your gut’s nervous system physically rewired.

It’s a mouse study, but it fits a pattern I’ve seen in my patients for years.

Here’s what the science supports for repairing the roads:

Try gut-directed hypnotherapy. An underused, evidence-informed tool we have for the nervous-system piece.

Feed your microbes with soluble fiber. Fiber feeds the microbes that produce short-chain fatty acids — the molecules that patch the lining after inflammation damages it. (Moayyedi 2014 meta-analysis, PMID 25070054) 38TERA DMN is an example of a quality prebiotic with evidence from a controlled microbiome study showing a significant increase in SCFAs (acetate) after 3 days of use and continued increase in acetate, propionate and butyrate across 15 days of use.

Try peppermint oil. Recommended by the ACG 2021 guidelines for IBS and abdominal pain. (Not for people with reflux.)

So the good news: The roads can be repaved. The wiring can be retrained. Follow for more gut health science and solutions.
    Every week, somebody asks what to do about micropl Every week, somebody asks what to do about microplastics. For a long time my answer was “we don’t have the human data yet.”

Now we do.

The 2026 Gut Microbes (PMC12818824) review pulls together the first real human research— and the pattern is concerning enough to act on, without being dramatic enough to panic about. Beneficial bacteria down. Pathogens up. Barrier function impaired.

I’m not here to scare you. I’m here to tell you what I actually do, and why your gut is nowhere near as helpless in this as the headlines suggest. Your microbiome is the most adaptable system in your body. Feed it well, and it does a remarkable amount of the repair work for you.

Save this for the next time someone you love starts spiraling about plastic.
    5 minutes of sleep. 2 minutes of exercise. 1 more 5 minutes of sleep. 2 minutes of exercise. 1 more year of life.

A study of 59,000 people just proved you don’t need a massive lifestyle overhaul to live longer — you need small, consistent wins across three areas.

    You’ve Been Pooping All Wrong by @trishapasrichamd You’ve Been Pooping All Wrong by @trishapasrichamd 

Look… everyone poops. And we all have questions. What’s normal? What’s that food doing in there? How can I poop like a pro?

    You can poop every single day and still be constip You can poop every single day and still be constipated.
I know that sounds counterintuitive— but as a gastroenterologist I see this constantly.

Constipation isn’t just about frequency. It’s about quality. If you’re straining, feeling incomplete, or sitting there for 10 minutes and still feel like something’s left behind— that’s constipation. Even if you went yesterday.

The number one cause? Not enough of the RIGHT kinds of fiber to fully move things through.

Save this if you’ve ever felt “regular” but not quite right. Your gut is trying to tell you something.
    I want you to sit with that number. One hundred gr I want you to sit with that number. One hundred grams of fiber a day. That’s not a typo.

Anthropological research on hunter-gatherer populations and studies of traditional societies still eating ancestral diets have found fiber intakes ranging from 50 to over 150 grams daily— from an enormous variety of plant sources including tubers, legumes, wild fruits, seeds, and fibrous vegetables.

Our gut microbiome evolved in that context. The bacterial populations that colonize our colon, the enzymes they produce, the metabolic pathways they run— all of it developed under conditions of fiber abundance and diversity. Then in a geologic instant, we shifted to a processed food diet delivering 15 grams from a handful of sources. The microbiome hasn’t had time to adapt. And we’re seeing the consequences: declining microbial diversity across industrialized populations, rising rates of colorectal cancer, metabolic disease, and inflammatory conditions— all with established connections to microbiome disruption.

The good news: the microbiome is responsive. You don’t have to reach 100 grams. Moving from 15 toward 30, 40, 50— from more diverse sources— produces measurable changes in bacterial composition and inflammatory markers.

Start where you are and move the number up.
