Conditions · Gut & Digestive Health

Gut problems have causes. We look for them.

Healing Advanced Solutions provides root-cause digestive care in Jacksonville, FL for bloating, IBS, SIBO, reflux, and food sensitivities, with functional testing reviewed by Catherine Seidle, APRN.

An IBS label describes symptoms; it does not explain them. Stubborn gut symptoms usually trace to something testable and treatable. Finding it is the job.

What's going on

One system, many failure modes.

Digestion is a chain: stomach acid, enzymes, motility, the microbiome, the gut barrier, and the immune tissue wrapped around all of it. A symptom like bloating is the smoke. The fire can be bacterial overgrowth, low acid, slowed motility, an unresolved infection, or a food trigger, and each one has a different fix.

That is why "eat more fiber and manage stress," true as it is, fails so many people as a complete answer. The routine matters for everyone; the driver is personal.

Common symptoms, and their likely drivers.

Bloating

Often traces to:

  • SIBO
  • Low stomach acid
  • Slowed motility

The most common complaint in this office, and the least specific. Which driver it is decides the fix.

Reflux & indigestion

Often traces to:

  • Meal timing & pressure
  • Trigger foods
  • Fermentation higher up

Often a plumbing and pressure story rather than a simple acid story, which is why blanket suppression sometimes disappoints.

Unpredictable bowels

Often traces to:

  • SIBO
  • Motility issues
  • Food triggers
  • Post-infectious change

The pattern that usually carries the IBS label. A label is not an explanation.

Food reactions

Often traces to:

  • Celiac disease
  • True allergy
  • Sensitivity
  • A strained gut lining

These get sorted, not guessed: allergy belongs with an allergist, celiac has a blood screen, sensitivities get tested against your real symptoms.

Red flags are different territory: blood in the stool, black tarry stools, unintentional weight loss, trouble swallowing, or new severe pain deserve prompt medical evaluation first.

History first, then targeted testing.

A real timeline narrows the suspects before a single test is ordered.

When it started, what changed, the antibiotics course two years ago, the surgery, the travel, the stress load: the story does more diagnostic work than most panels. Then testing is matched to the suspects, ordered only where it changes the plan, and usually anchored by the 75-minute functional medicine evaluation.

One note on "leaky gut," since you will meet the term everywhere: the research on intestinal permeability is real, and the term is also stretched into an explains-everything diagnosis. We test and treat what is measurable.

  • History before tests
  • Testing only when it changes the plan
  • Staged protocols

Testing we use.

Comprehensive stool analysis

The microbiome, digestion markers, and inflammation read together, so the plan targets what is actually off.

SIBO breath testing

The test that finds bacterial overgrowth in the small intestine, one of the most common findings behind stubborn bloat.

Food-sensitivity panels

Used selectively: leads worth testing against your real-world symptoms, not a standalone diagnosis.

Nutrient status

Absorption problems leave fingerprints. Iron, B12, and vitamin D tell on a gut that is not doing its job.

Celiac screening joins the panel where the story points to it, and results are read against both standard and functional ranges; our lab testing page explains the closer read.

What care looks like.

  1. A free consultation

    Ten to fifteen minutes. Describe the pattern and we will help you decide whether testing would change the plan.

  2. The evaluation

    Your full timeline, from birth to present, with testing chosen to match the suspects it raises.

  3. A staged plan

    Address the driver, rebuild the routine around it, and know at each stage what we are checking for.

  4. Retest what was abnormal

    Gut work is iterative, in weeks-to-months arcs with checkpoints. We will tell you at each one what is working, and what is not.

Common questions.

The things patients ask most.

Ask us anything
How do I actually improve my gut health?

The answer starts with why yours is off, because the fixes differ by cause. Fiber diversity, fewer ultra-processed foods, sleep, and stress management help almost everyone; beyond that, the right move depends on whether the driver is a motility problem, bacterial overgrowth, an infection, low stomach acid, or a food trigger. Guessing is how people end up on year three of elimination diets.

What is SIBO?

Small intestinal bacterial overgrowth: bacteria that belong in the colon setting up shop in the small intestine, where they ferment food early and produce the bloating, gas, and unpredictable bowel habits that get labeled IBS. It is testable and treatable, and it is one of the most common findings behind stubborn bloat.

Is IBS just something I have to live with?

IBS is a real diagnosis, but it is a description of symptoms, not an explanation. A meaningful share of people carrying the label turn out to have an identifiable driver, such as SIBO, a food trigger, or a motility issue, that responds to targeted treatment. An unexplained label is worth revisiting, not settling for.

Do food sensitivity tests work?

They are a tool, not an oracle. Blood-based sensitivity panels can generate leads worth testing against your actual symptoms, but they are not diagnoses. We use them selectively, alongside elimination protocols and history.

How do I restore gut health after antibiotics?

Usually your microbiome recovers substantially on its own within weeks to months, helped by fiber diversity and fermented foods. If digestion stays off long after a course, that is worth investigating rather than supplementing blindly, because post-antibiotic disruption can unmask an underlying issue.

When is a gut symptom an emergency?

Blood in your stool, black tarry stools, unintentional weight loss, persistent vomiting, difficulty swallowing, or new severe pain deserve prompt medical evaluation, and a colonoscopy referral when indicated, before any functional workup. We take those symptoms seriously.
