Your Gut Is Talking. Here's How to Listen.

Maria came in last month complaining she was exhausted all the time. She'd been working double shifts, eating fast — a lot of drive-through, a lot of café cubano and pastelitos to get through the afternoon. Her blood work came back fine. Thyroid, fine. Iron, fine. But when I asked about her digestion, she paused. "Now that you mention it, I've been bloated for months. I thought that was just normal."

It's not normal. And it's not in her head either.

The gut does a lot more than digest food. It houses trillions of bacteria — good, bad, and neutral — that together form what scientists call the microbiome. This community helps regulate your immune system, produce certain vitamins, and send signals directly to your brain through what's called the gut-brain axis. When that community is balanced, you feel good. When it's disrupted, you feel it everywhere — in your mood, your skin, your sleep, your energy.

In Central Florida, I see gut issues year-round, but they spike in patterns. After a round of antibiotics — which wipe out good bacteria along with the bad — after the holidays when everyone's been eating differently, and during allergy season, because your immune system and your gut are more connected than most people realize. Add in the summer heat that makes cooking the last thing you want to do, and it's easy for things to go sideways for months without anyone putting a name to it.

Here's what disruption actually looks like in a real patient: chronic bloating, constipation that alternates with loose stools, heartburn that keeps coming back, skin that's suddenly breaking out, fatigue that doesn't make sense, or anxiety that feels worse than usual. These aren't separate problems. They might all be pointing to the same place.

So what can you actually do about it?

Start with food — not an overhaul, just shifts. Add one fermented food to your daily routine. Plain yogurt (not the sweetened kind), kefir, or a small portion of kimchi or fermented curtido, which you can find at most Hispanic grocery stores on Orange Blossom Trail or near Narcoossee Road. These add live cultures back to your gut. Fiber is the other big one — specifically the kind that feeds good bacteria. Black beans, lentils, oats, ripe plantains, and almost any vegetable that grows underground. Most Americans get about 15 grams of fiber a day. The goal is closer to 25 to 35.

Reduce what's working against you: ultra-processed food, excessive sugar, and alcohol. Not never — just most days, most meals. The gut recovers fast when you give it a chance.

Stress matters more than people expect. The gut has its own nervous system — sometimes called the second brain — and it responds directly to stress hormones. This is especially true for patients I see who are working multiple jobs, sending money home, managing families with limited support. Chronic stress alters the gut environment over time. Even getting consistent sleep hours makes a measurable difference.

Probiotics from a supplement can help, but I want to be honest: the evidence is more nuanced than the marketing suggests. A probiotic taken during or right after antibiotics is well-supported. A general probiotic for general wellness? The research is still catching up. Real food sources are more reliable most of the time.

When to See a Doctor

Some gut symptoms need more than a dietary change. Come in if you notice blood in your stool or toilet water, if your stool is consistently black or tarry, if you've lost weight without trying, if you have persistent abdominal pain that doesn't ease up within a few days, or if your symptoms have suddenly changed after years of being the same. These are things I want to look at in person — they can point to conditions that deserve a closer evaluation.

Also come in if you've been managing what you assume is just "how your stomach is" for years. Patients live with treatable conditions far too long because they assume nothing can be done. That's rarely true.

Maria, by the way, made some small changes — more beans, less drive-through, a cup of kefir in the morning — and came back two months later saying she felt like herself again. No prescription required.
