What’s actually going on
How I think about this.
Digestive symptoms are one of the most undertreated presentations in conventional medicine. The standard workup rules out the disease (colonoscopy clean, celiac negative, lactose tolerance normal) and stops. That leaves the vast middle ground where the gut is not diseased but is also not working well. Bloating after meals. Irregularity. Sensitivities that keep widening. Fatigue that maps to digestion.
This middle ground is where I see most of my patients. The drivers are usually dysbiosis (the bacterial population in the gut is out of balance), a compromised gut barrier letting partially digested food and bacterial fragments into systemic circulation, stomach acid and enzyme insufficiency, eating under stress (which shuts down digestion before it starts), and food sensitivities operating below the IgE allergy threshold.
The gut is also where most of the rest of your biology gets shaped. Inflammation, immune signaling, hormone metabolism, neurotransmitter production. A patient who fixes their gut almost always notices changes well beyond digestion.
The physician’s lens
How I read this in practice.
I read gut symptoms with a structured stool panel that maps the bacterial population, the inflammation level, the digestive markers (elastase, fat, fiber), and any pathogen presence. Where food sensitivities are suspected, I add a food sensitivity IgG/IgA panel. The metabolomic panel catches bacterial overgrowth signals when the stool panel is borderline. I read these together, not separately.

Metabolomics.
Urinary organic acids read the upstream patterns of energy production, neurotransmitter balance, detoxification, and recovery.

The data that explains it.
Gut work needs a real stool panel, not a colonoscopy report. The GI Effects panel reads what is actually growing in the gut, how the gut barrier is holding up, and what the digestive output looks like. The food sensitivity panel comes in when symptoms cluster around specific meals.
While you wait
Moves worth making before testing.
These are the levers I’d pull while we set up the workup. Most of them produce real signal inside two weeks.
- Slow the pace of meals. Chew each bite until it is liquid before swallowing.
- Pull ultra-processed foods for two weeks. Track what changes.
- Keep a simple symptom log against meals before you spend money on testing.
- Eat in a state where you can actually relax. The vagus nerve runs digestion.
If two weeks of the basics doesn’t move the needle, that is exactly the kind of presentation a Precision Call exists for. Your biology is telling you something the lifestyle layer cannot fix on its own.

The role of gut health in autoimmunity.
Most autoimmune disease has a gut layer. The mechanism is established, the interventions are accessible, and addressing the gut almost always changes the trajectory even when conventional care continues.

Understanding dysbiosis: when gut bacteria go rogue.
Dysbiosis is what happens when the bacterial community in your gut shifts in the wrong direction. It is a measurable, reversible state, and it is upstream of more chronic symptoms than most patients realize.

Leaky gut. Fact, fiction, or somewhere in between.
Leaky gut is real as a physiological phenomenon and oversold as a diagnosis. The honest clinical position is between dismissal and panic, and it depends on what the patient is actually asking.

Something else on your mind?
Fatigue and low energy
When the tank stays low no matter how much you sleep.
Brain fog
The lights are on but the signal feels weak.
Poor sleep
Either you can't fall asleep, or you can't stay asleep.
Digestive issues
Bloating, irregularity, sensitivities that keep widening.
Mood and stress
Patience runs short, recovery from stress takes longer.
Hormonal imbalance
Energy, sleep, libido, and weight stop responding to the basics.
Perimenopause
The years when the body's hormonal rhythm changes, before the period stops.
Low libido
Desire that used to be reliable is gone or muted. Both sexes, both directions.
Hair loss
Thinning, shedding, or texture changes that didn't used to happen.
Erectile dysfunction
ED is the canary. The body is telling you something about vascular and hormonal health.
Weight loss resistance
You eat well, you train, the scale doesn't move. Something deeper is in the way.
High cholesterol concern
Your last lab flagged it. You want a second opinion before you take a statin.
High blood pressure concern
The reading came back elevated. You want the full picture before you start a prescription.
Insomnia
You can't get to sleep. You can't stay asleep. Or both.
Athletic recovery problems
You train hard. You don't bounce back. Something physiological is in the way.
Headaches and migraines
Recurring headache patterns the standard workup hasn't solved.
Joint pain
Pain in one joint is often a local problem. Pain that travels, or pain in multiple joints, is usually a systemic one.
Anxiety
Some anxiety is psychological. Much of what shows up in clinic is biological with a psychological face.
Acne and skin issues
The skin is rarely the problem. It is the most visible report on what is happening one layer down.
Thyroid symptoms
Cold all the time. Hair shedding. Sluggish mornings. A 'fine' TSH that explains none of it.
PMS and cycle issues
A difficult cycle is often a window into how your body handles hormones across the rest of the month.
Food cravings
Cravings are biology pulling for what it needs, often dressed up as what it can get easily.
Chronic allergies
New or worsening allergies in adulthood usually point to a barrier and an immune tone, not a specific allergen.
