Bloating isn't Normal

Bloating has become so common that many people assume it's normal. They expect to feel uncomfortable after meals, live with gas and abdominal pressure, or simply accept digestive discomfort as part of getting older.

The truth is that bloating is not normal. It is communication.

Your digestive system is trying to tell you that something is interfering with its ability to properly break down, absorb, and process food. While many people immediately blame a specific food, the reality is that digestive dysfunction is often much more complex.

As a Board Certified Nutritional Therapy Practitioner, one of the biggest mistakes I see is people focusing only on the symptom instead of asking why the symptom exists in the first place.

Stress: The Overlooked Digestive Disruptor

One of the most overlooked causes of digestive dysfunction is stress.

Digestion requires the body to be in a parasympathetic state, often referred to as "rest and digest." When we are chronically stressed, stuck in fight-or-flight mode, rushing through meals, multitasking, or eating while distracted, blood flow and energy are diverted away from digestion.

This can contribute to:

• Reduced stomach acid production
• Poor enzyme secretion
• Slower digestion
• Increased bloating
• Altered gut motility
• Increased intestinal permeability

Many people spend hundreds of dollars on supplements while continuing to eat in a stressed state every day.

One of the simplest and most effective ways to support digestion is to calm the nervous system before eating. Before your meal, try practicing the "double inhale" breathing technique or simply take three slow, deep breaths through your nose, allowing your belly to expand. This helps stimulate the vagus nerve and encourages your body to shift into a parasympathetic state where digestion can function properly.

I also encourage clients to sit down at a table when they eat, preferably with good company and without a television, phone, or other screen in front of them. Screens tend to keep us mentally engaged and distracted, making it harder for the body to fully enter a relaxed digestive state.

The Processed Food Problem

Modern processed foods can place a significant burden on digestive health. They receive a lot of the blame for bloating, and honestly, much of that blame is deserved.

Highly processed foods often contain:

• Artificial flavors and preservatives
• Industrial seed oils
• Emulsifiers
• Synthetic colors
• Excess sugar

Research suggests some food additives and emulsifiers may negatively impact the gut lining and microbiome. Processed foods also tend to displace nutrient-dense foods that support digestive health and tissue repair.

While processed foods may not be the sole cause of digestive issues, they can contribute to inflammation, microbiome imbalances, digestive dysfunction, and increased intestinal permeability over time.

Food Sensitivities: Not the Same as Food Allergies

Many people are familiar with food allergies, but food sensitivities are very different.

Food allergies typically create an immediate immune response and can sometimes become life-threatening.

Food sensitivities are often delayed reactions that may occur hours or even days after exposure. In fact, it can sometimes take up to 72 hours before symptoms appear. This delayed response makes identifying trigger foods incredibly challenging.

A food you ate on Monday may not create symptoms until Wednesday or Thursday, causing many people to blame the wrong food entirely.

Symptoms can include:

• Bloating
• Gas
• Brain fog
• Fatigue
• Skin issues
• Joint discomfort
• Digestive upset

One challenge is that people often continue eating foods they are sensitive to because the reaction is delayed and difficult to connect back to the original food.

This is one reason I utilize bio-resonance testing in my practice. Unlike traditional allergy testing, it can help identify current sensitivities that may be contributing to inflammation, digestive distress, and other chronic symptoms.

The Microbiome: Your Internal Ecosystem

Your digestive tract contains trillions of microorganisms collectively known as the gut microbiome.

These tiny organisms are constantly at work. While many of them are beneficial, they also produce gases as they break down and ferment food. Excessive fermentation can contribute to bloating, pressure, abdominal discomfort, and changes in bowel habits.

The microbiome plays a far bigger role than simply digesting food. Certain microbes can influence inflammation, immune responses, nutrient absorption, mood, metabolism, and even the health of the intestinal lining itself.

These microbes influence:

• Digestion
• Immune health
• Nutrient absorption
• Inflammation
• Mood and brain function
• Metabolism

When beneficial bacteria decrease or undesirable organisms become dominant, symptoms such as bloating, constipation, diarrhea, reflux, and abdominal discomfort may occur.

This is why testing can be incredibly valuable. I now offer GI microbiome testing through Tiny Health, which provides a detailed look at the health of the gut ecosystem and can help identify potential imbalances contributing to symptoms.

Rather than guessing, testing allows us to gather meaningful information and create a more personalized strategy.

What Are Prebiotics, Probiotics, and Postbiotics?

These terms are often used interchangeably, but they serve very different purposes.

Because of their direct relationship to the microbiome, they are frequently marketed as solutions for bloating, digestive discomfort, and gut health concerns. I cannot count the number of times someone has asked me, "What probiotic should I take?"

The reality is that the answer is not nearly as simple as supplement marketing would have us believe.

Let's break them down.

Prebiotics

Prebiotics are compounds that feed beneficial bacteria already living in the gut.

Think of them as fertilizer for your microbiome.

Common food sources include:

• Garlic
• Onions
• Leeks
• Asparagus
• Jerusalem artichokes
• Green bananas

Without adequate prebiotics, beneficial bacteria may struggle to thrive. BUT, these are also often common food sensitivities.

Probiotics

Probiotics are live microorganisms that may help support microbial balance.

Some of the most common strains belong to groups such as:

• Lactobacillus species
• Bifidobacterium species

Not everyone needs a probiotic, and selecting the wrong strains may not provide the desired results. In some cases, introducing additional bacteria into an already imbalanced system may actually worsen symptoms.

Post-biotics

Post-biotics are beneficial compounds produced when bacteria ferment fibers and nutrients.

Honestly, these are my personal favorite.

One of the most important postbiotics is butyrate.

Butyrate helps:

• Fuel cells lining the colon
• Support gut barrier integrity
• Support healthy inflammatory responses
• Promote digestive health

You can think of butyrate as one of the primary fuels that keeps the intestinal lining healthy and resilient. You can consume this as a supplement, but butter is also an excellent source of butyrate too! ( Like you need another excuse to eat more butter, haha)

Do You Really Need a Probiotic?

This is one of the most common questions I receive.

The answer is: maybe.

Many people purchase probiotics without knowing what organisms they actually need. Without testing, we are often making educated guesses.

I generally do not recommend staying on the same probiotic for extended periods of time. In most cases, I prefer rotating products and limiting use of a single formula to around 30 days. Long-term use of one product may encourage overrepresentation of certain strains rather than supporting microbial diversity.

When testing is unavailable, I often prefer focusing on supporting the environment of the gut rather than blindly introducing large amounts of bacteria.

One of my favorite tools is sodium butyrate because it supports the health of the gut lining, supports healthy inflammatory responses, and helps create conditions where beneficial bacteria can thrive naturally.

Before the Microbiome: The Foundations Matter

One of the biggest mistakes I see in functional health is jumping directly to microbiome support without addressing foundational systems first.

Before I focus heavily on the microbiome, I evaluate:

• Circadian rhythm health
• Oral health
• Stomach acid production
• Liver function
• Gallbladder function
• Pancreatic enzyme production
• Overall inflammation levels

In my experience, circadian rhythm is one of the most powerful controlling factors of digestive health. Your gut operates on a clock. Digestive enzyme production, stomach acid secretion, gut motility, microbial activity, and tissue repair all follow circadian rhythms.

You can support your circadian clock by:

• Consistent sleep and wake times
• Morning sunlight exposure
• Limiting bright light exposure after sunset
• Eating meals on a predictable schedule
• Avoiding late-night eating
• Spending time outdoors during daylight hours

Before worrying about which probiotic to take, I would much rather see someone improve their sleep, get morning sunlight exposure, reduce evening artificial light, and create consistent meal timing habits.

Those foundational habits often move the needle more than supplements alone.

Digestive symptoms are rarely random. Bloating, gas, reflux, constipation, diarrhea, and discomfort are often the body's way of waving a flag and asking for attention. While it's tempting to blame the last thing you ate or search for the next supplement, true healing often comes from stepping back and looking at the bigger picture. Your nervous system, circadian rhythm, stomach acid production, microbiome, food sensitivities, liver function, and daily habits all work together as part of a larger ecosystem. When one area begins to struggle, the effects ripple throughout the entire digestive tract. Instead of silencing symptoms, get curious about them. Your body is communicating. The goal is not to fight the message—it's to understand what it's trying to tell you.
