The 4 Root Causes of Digestive Problems (And How to Heal Them Naturally)

Most of us have dealt with digestive issues at some point, but we don’t always recognize them for what they are.

You might feel bloated after meals, foggy in the afternoon, randomly constipated, or constantly battling skin flare-ups and food sensitivities. You try to eat well, drink more water, and maybe cut out gluten or dairy… and yet the symptoms persist.

Sound familiar?

These symptoms are so common that many people just chalk them up to “getting older” or “having a sensitive stomach.” But the truth is, they’re signs that your gut is struggling and it’s trying to get your attention.

While gut health can feel overwhelming, the real root causes behind most digestive problems often boil down to just four key issues. Once those root causes are identified and addressed, the gut can start to heal, and everything else in the body begins to work better, too.

In this post, we’ll cover the four primary root causes of digestive issues and how to naturally start healing from them.

Why the Gut Matters So Much

The digestive system does way more than just break down food.

It plays a major role in:

• Nutrient absorption
• Immune function
• Neurotransmitter production (like serotonin)
• Hormone balance
• Inflammation and water retention
• Even how much energy and focus you have day to day.

In fact, around 90% of autoimmune issues are linked to something called intestinal permeability (also known as leaky gut), which often stems from imbalances like the ones below.¹

The 4 Root Causes of Digestive Problems

1. Parasites

Parasites are organisms that live off their host, which, in this case, means living inside the body and using its resources to survive.

They’re more common than most people think, with global estimates showing around 24% of people have at least one.²

If you’re not sure if parasites could be behind your symptoms, here are 7 clear signs to look out for, and what to do if they show up.

How parasites are contracted:

• Contaminated water (often while traveling or camping)
• Undercooked meat
• Salad bars (produce washed with unsafe water)
• Soil (especially from gardening or farming)
• Contact with feces (even from kids or pets)
• Blood or sexual transmission

And believe it or not, some of the hidden signs of parasite infection are so subtle they’re easy to miss.

Types of parasites:

• Protozoa: Single-cell parasites like Giardia, often from water
• Helminths: Worms like tapeworms, roundworms, flatworms
• Ectoparasites: External parasites like ticks and fleas

Common symptoms:

• Diarrhea or greasy stools
• Bloating, cramps
• Night sweats
• Acne (especially on the back, chest, or forehead)
• Fatigue, especially after eating
• Dehydration

Supportive remedies:

• Biofilm disruptors (enzymes like proteases to break down the protective layer parasites hide in)
• Herbs such as black walnut hulls, berberine, wormwood, garlic, pumpkin seeds, and Mimosa pudica. Curious which herbs are most effective? Check out these 9 powerful herbs that help kill parasites and support your body’s detox.

And if you’re considering a parasite cleanse, be sure to grab The Ultimate Parasite Cleanse Starter Kit. It includes the exact herbs and support tools I recommend, all bundled into an easy 8-week plan.

2. H. Pylori

Helicobacter pylori (H. pylori) is a spiral-shaped bacterium that embeds in the stomach lining.

It can quietly disrupt digestion and immune function over time and is estimated to affect around 60% of the adult population.³

How it spreads:

• Improper handwashing
• Contaminated food or water
• Soil or animal exposure

Common symptoms:

• Nausea (especially in the morning or shortly after meals)
• Acid reflux or gastritis
• Loss of appetite
• Anemia or B12 deficiency
• Burping after meals
• Bloating and stomach discomfort

Testing options:

• A 3-day stool test is the most reliable.

Supportive remedies:

• Mastic gum (used traditionally in Greek and South American medicine)
• Zinc carnosine to rebuild stomach lining
• Glutamine, aloe vera, and marshmallow root for healing
• Probiotics (after addressing H. pylori)
• Avoid betaine HCl or pepsin during active infection — it can worsen inflammation

3. Bacterial Overgrowth (SIBO)

Small Intestinal Bacterial Overgrowth (SIBO) happens when bacteria, even the beneficial kind, start multiplying in the wrong place, mainly in the small intestine, where things are meant to stay relatively sterile.

Causes of overgrowth:

• Stress (which affects gut motility and valve function)
• Past antibiotic use (even just once)
• Alcohol or highly processed diets
• Birth control pills
• Low bile or stomach acid
• Liver or gallbladder issues

Symptoms to look for:

• Bloating, especially near the belly button
• Gas or flatulence
• Discomfort or fullness after eating
• Constipation or loose stools
• Burping and indigestion

Testing:

• A stool test or urine test is preferred.

Supportive remedies:

• Antimicrobial herbs like oregano oil, olive leaf, clove, caprylic acid
• Biofilm disruptors
• Hold off on probiotics until overgrowth is reduced, as they may worsen symptoms if introduced too early

4. Candida Overgrowth

Candida is a type of yeast that normally exists in small amounts in the gut, but under the right (or rather, wrong) conditions, it can grow out of control.

This is one of the most common root causes of digestive issues.

What triggers candida:

• Antibiotics (which kill bacteria but not yeast)
• Diets high in refined carbs and sugars
• Alcohol and chronic stress
• Birth control
• Weakened immune function

Symptoms of overgrowth:

• Brain fog and fatigue
• Sugar cravings
• Yeast infections (in both women and men)
• Fungal nails or athlete’s foot
• Skin issues
• Sinus congestion or recurring infections

Best testing option:

• A urine test is highly effective for detecting candida and its metabolites

Supportive remedies:

• Antifungal herbs: grapefruit seed extract, oregano, clove, caprylic acid
• Reintroduce probiotics gradually, start with Saccharomyces boulardii, then work toward multi-strain formulas
• Use gut-healing nutrients like glutamine and zinc carnosine to repair the intestinal lining

Testing Before Guessing

Each of these root causes may appear similar on the surface, but they require distinct approaches to be truly resolved.

The most reliable way to find out what’s going on:

• Stool test (for parasites, H. pylori, bacterial overgrowth)
• Urine test (for candida and other imbalances)

If you’re ready to begin your gut healing journey, here’s how to prepare for a protocol the right way.

Quick Recap

✅ Digestive problems aren’t just “normal” — they’re signs your body needs support
✅ The four major root causes: parasites, h. pylori, bacterial overgrowth (SIBO), candida overgrowth
✅ Stool and urine tests are key to knowing what’s happening
✅ Natural protocols work best when they include: biofilm disruptors, targeted herbal support, gut-rebuilding nutrients

Final Thoughts

If you’re feeling tired of chasing symptoms or constantly feeling like something’s “off,” this is your starting point. The gut is truly the foundation for much of your health, and once you rebalance it, everything else tends to fall into place.
