5 Mistakes That Keep Your Gut Symptoms Going — A Naturopath Explains
By Joana Amram, Registered Nutritional Therapist & Naturopath (ANP)· Lisbon, Portugal
Most people who come to me have already tried. They have changed their diet, bought supplements, read articles, cut foods out. They are not lacking in effort or motivation. What they are missing is direction — because several of the most common gut health approaches are either incomplete or actively counterproductive.
Here are the five mistakes I see most often, and what to do differently.
Mistake 1: Chasing Symptoms Instead of Asking Why They Started
This is the most fundamental error, and it underpins all the others.
Bloating, constipation, reflux, and IBS are not conditions — they are symptoms. They are your gut signalling that something in the underlying process is not working. When treatment focuses on suppressing or managing those signals without investigating their cause, it is the equivalent of covering a warning light on your car dashboard with tape. The light stops blinking. The problem remains.
The most important question is not what are my symptoms but why do I have them. When did they start? Was there a triggering event — a course of antibiotics, a bout of food poisoning, a stressful period, a significant dietary change? What makes them better or worse? What has never been investigated?
Until you have a credible answer to why, any treatment you try is essentially a guess. Some guesses get lucky. Most do not. And even when they provide temporary relief, they rarely provide lasting resolution — because the underlying driver is still present.
Mistake 2: Snacking Constantly
Eating frequently feels virtuous. It is marketed as a way to "keep your metabolism going" and "avoid blood sugar crashes." For gut health, however, constant eating is one of the most disruptive habits you can have.
Between meals, your gut runs a housekeeping cycle called the migrating motor complex (MMC) — a sweeping wave of contractions that clears undigested food residue and bacteria downward through the small intestine toward the colon. This is how your gut self-regulates bacterial populations, prevents fermentation in the wrong place, and maintains normal motility.
The MMC only activates when you are not eating — during genuine fasting gaps. The moment you eat or drink anything other than plain water, the MMC pauses. If you are eating every 1–2 hours, that cycle never completes. Food and bacteria accumulate in the small intestine. Fermentation builds up. Bloating, gas, and sluggish digestion follow.
Three proper meals per day, with gaps of 4–5 hours between them and nothing in between except water, is one of the simplest and most effective gut interventions available. It costs nothing and requires no supplements. In many cases it produces more improvement than months of dietary restriction.
Mistake 3: Over-Relying on Probiotics
Probiotics are one of the most aggressively marketed supplements in the wellness space, and they genuinely help some people in some situations. But they are not the universal gut support they are presented as — and for a significant subset of people, they actively make things worse.
Here is why: the gut is not simply depleted of good bacteria and in need of a top-up. Gut dysbiosis — imbalance in the microbiome — is a far more complex picture involving the composition, diversity, and location of bacterial populations. Adding billions of lactobacillus and bifidobacterium to that picture without knowing what is already going on can be unhelpful at best and harmful at worst.
Most significantly, in SIBO — Small Intestinal Bacterial Overgrowth — probiotics can worsen symptoms substantially. SIBO involves bacteria residing in the small intestine, where they should not be. Most commercial probiotics are lactobacillus-based, and lactobacillus is specifically associated with hydrogen-type SIBO. Adding more of it to an already overgrown small intestine adds fermentative load, increases gas production, and worsens bloating and discomfort.
The principle to apply is: test before you supplement, or at minimum understand your symptom picture before reaching for a probiotic. If you have significant bloating that worsens after taking probiotics, stop taking them and investigate whether bacterial overgrowth is present before continuing.
Mistake 4: Ignoring Stomach Acid and Digestive Enzymes
Digestion is a cascade. It begins with stomach acid, and every subsequent step depends on what happens there. When stomach acid is adequate, protein is broken down properly, digestive enzymes are activated at the right time, the rest of the small intestine receives the correct signals to continue the process, and bacteria that arrive via food are neutralised before they can colonise where they do not belong.
When stomach acid is insufficient — which is common, and increasingly so with age, chronic stress, and long-term use of acid-suppressing medications — the entire cascade is compromised from the first step.
Food that is inadequately broken down in the stomach reaches the small intestine partially undigested. Bacteria that should have been killed in the stomach survive and reach the gut in higher numbers. The downstream digestive signals are weaker. The result is poor nutrient absorption, increased bacterial fermentation, bloating, and symptoms that look very much like excess stomach acid — leading many people to take antacids, which worsen the underlying problem further.
The irony is significant: reflux, heartburn, and burping — the symptoms most commonly associated with excess acid — are frequently caused by low acid. Acid in the wrong place (pushed upward by gas and fermentation) creates burning sensations, but the root cause is insufficiency rather than excess.
If you have been on proton pump inhibitors long-term, if you bloat or feel heavy within 30–60 minutes of eating, if you experience undigested food in your stool, or if you have a history of frequent gut infections — stomach acid support is worth investigating before further supplementation.
Mistake 5: Eating "Healthily" While Missing the Basics
The clean-eating world has produced a particular form of gut-health confusion: people who are eating exceptionally healthy diets and feeling terrible.
There is a pattern I see regularly in practice. Someone cuts gluten, cuts dairy, cuts sugar. They eat salads, smoothies, vegetables, legumes, and wholegrains. Their diet looks excellent on paper. Their gut is still a mess.
Several things can explain this. First, many "healthy" foods are highly fermentable — broccoli, onions, garlic, apples, beans, lentils. In a gut with bacterial overgrowth or dysbiosis, these foods produce significant fermentation, bloating, and discomfort regardless of how nutritious they otherwise are. Eating more of them when the microbiome is imbalanced can feel like the opposite of helpful.
Second, the basics of digestive function — meal timing, eating without rushing, adequate chewing, eating in a calm state — are often neglected in favour of optimising food choices. Yet these fundamentals determine how well any food is digested, regardless of its nutritional content. The best meal in the world is poorly processed if you are eating it at your desk while answering emails under stress.
Third, extreme dietary restriction narrows the microbiome. A diverse gut microbiome is built on dietary diversity — a wide range of plant foods, fibres, and fermented foods feeding a wide range of bacterial species. Restriction, even when motivated by genuine symptom management, can progressively narrow microbial diversity, leaving the gut more vulnerable and more reactive over time.
Eating healthily is necessary but not sufficient. The foundation of digestive health is structured meal timing, eating in a relaxed state, adequate chewing, and addressing the underlying reasons why certain foods are triggering reactions — not simply avoiding them indefinitely.
Where to Go From Here
If any of these mistakes resonate, the most important next step is not to add another supplement or cut another food. It is to ask the question that changes everything: why?
Why did my symptoms start when they did? What is the root cause of what I am experiencing? What has never been properly investigated?
A thorough root-cause assessment — covering your full health history, symptom patterns, dietary habits, and lifestyle — is the foundation of any protocol that actually resolves symptoms rather than just managing them.
If you have been trying on your own for a while and the answers are not coming, that is not a failure. Gut health is genuinely complex, and identifying the specific drivers in your individual case often requires experienced clinical eyes.
