Gut & Digestive Health

Digestion, immunity and energy, understood before they become a diagnosis.

1. Is This Path for You?

Who this page is for

This page is not only for people who have been diagnosed with IBS or another digestive condition.

It's for the proactive adult, typically 55 and older, who is doing most things right and still notices that digestion isn't quite what it used to be. You may recognize yourself here:

Bloating, gas or discomfort after meals that didn't bother you before.
Reflux or heartburn that shows up more often, or after foods that never used to trouble you.
Bowel habits that have become less predictable — more constipation, looser stools, or swinging between the two.
Energy or mood that dips after eating, or a sense that meals "sit" longer than they used to.
You've been told it's "just IBS" or "just stress," without a closer look at why.
Your last physical didn't include any real look at digestion, unless you brought it up yourself.

It's also for people who feel fine and want to keep it that way. The gut is closely tied to the immune system and to how the body absorbs nutrients, so quiet imbalances can affect more than digestion, long before they cause an obvious problem.

If you'd rather understand your gut than simply live around it, this path was built for you.

Reactive Care: Wait for symptoms to worsen → Chase a diagnosis

Proactive Care: Look deeper now → Protect your digestion, immunity and energy

Core takeaway: Feeling "fine" isn't the same as digesting well. Discomfort you've learned to live with is still worth a closer look.

2. What Your Routine Checkup Isn't Telling You

What we're actually looking at

A routine annual visit rarely includes a real look at digestion, unless symptoms are severe enough to prompt a referral. A quick question about your stomach can't tell you much.

Here's the difference in plain terms.

A routine checkup looks for obvious disease. It usually doesn't examine gut bacteria, digestive function or the low-grade inflammation that can build up long before a diagnosis like IBS, reflux disease or a nutrient deficiency is made.

A comprehensive digestive evaluation looks at the fuller picture. Depending on your history, Dr. Potharlanka may evaluate:

Comprehensive digestive and stool analysis: a look at gut bacteria balance, digestive function and markers of inflammation, such as fecal calprotectin, which can help distinguish IBS from an inflammatory condition.
Small intestinal bacterial overgrowth (SIBO): breath testing when bloating, gas or irregular bowel habits suggest bacteria have overgrown where they shouldn't be.
Food sensitivities and intolerances: distinguishing a true sensitivity from a general dietary pattern.
Nutrient absorption: iron, vitamin B12, vitamin D and other levels that can quietly drop when the gut isn't absorbing well.
H. pylori and reflux risk: testing for the bacteria linked to ulcers and some reflux and stomach conditions.
Whole-body inflammation: markers such as hs-CRP, which connect gut health to inflammation elsewhere in the body.

Core takeaway: Bloating or "just feeling off" isn't something to live with by default, and it isn't always visible on a standard panel.

3. The Quiet Years

When the right time is to look deeper

Changes in the gut often build quietly, long before there's an obvious diagnosis. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), digestive diseases affect an estimated 60 to 70 million Americans each year.

During these quiet years, small imbalances in digestion, gut bacteria and the gut lining can affect energy, immunity and mood well before symptoms are severe enough to send someone to a doctor. A large share of the body's immune tissue sits in and around the gut, so an ongoing imbalance there can influence far more than digestion alone.

That makes these quiet years the most valuable time to act. Addressing a gut imbalance early is usually easier than untangling a longer-standing problem.

Part II

Signs It's Time to Look Deeper

Signs that now is the right time to look deeper

You have bloating, gas or irregular bowel habits that have become a regular part of life.
Reflux or heartburn shows up more than occasionally, or you reach for antacids regularly.
You've been told it's "just IBS" or "just stress," without more investigation.
Inflammatory bowel disease, celiac disease or colon cancer runs in your family.
Your energy, skin or mood seem tied to what and when you eat.
You feel well and want a baseline so future changes can be measured against something real.

That last one matters more than people expect. A baseline taken while you feel good becomes the reference point for every decision afterward.

Core takeaway: The best time to understand your gut is before it forces the issue.

4. How Your Gut Works Together

Where the pieces connect

Digestion isn't one organ. It's a team that decides how well you absorb what you eat, and how well you defend yourself along the way. Here's who's involved.

The gut lining (the gatekeeper). A single layer of cells decides what nutrients pass into the bloodstream and what stays out. When this barrier is under stress, inflammation can follow.

Gut bacteria (the ecosystem). Trillions of bacteria help digest food, produce certain vitamins and train the immune system. Balance across the community matters more than any single "good" or "bad" species.

Digestive enzymes and bile (the processing plant). Produced by the stomach, pancreas and liver, they break food down so nutrients can actually be absorbed rather than passing through unused.

The immune system (the defense force). A significant share of the body's immune tissue is located in and around the gut, which is part of why gut health and immune resilience are so closely linked.

The gut-brain connection (the two-way line). The gut and brain communicate constantly through the nervous system, which is part of why stress can upset digestion, and why digestion can affect mood.

When one part of the team struggles, the others feel it. That's why we look at the whole system, not one symptom.

Core takeaway: Your gut is a system, so we treat it as one.

5. Today's Numbers, Tomorrow's Freedom

Why this protects your long-term vitality

There is a difference between lifespan (how long you live) and healthspan (how long you live well). Digestion, energy and immunity sit close to the center of that gap.

A well-supported gut is associated with:

Steadier energy. Fewer crashes, less afternoon fog, more good days.
Stronger immune resilience. A well-balanced gut supports the body's everyday defenses.
Better nutrient absorption. Getting real benefit from the food you eat, not just calories.
Fewer digestive surprises. Less unpredictability around meals, travel and social plans.
A calmer gut-brain connection. Steadier mood and clearer thinking.

The goal is not a perfect gut or a list of forbidden foods. The goal is to protect the systems that let you keep doing what you love: traveling, sharing meals with family, staying comfortable and confident day to day.

Core takeaway: Gut health isn't about eliminating every food. It's about understanding what actually works for your body.
