Are Biofilms Preventing You From Healing?

If you've ever scrubbed the slippery film from your pet's water bowl—or had plaque removed from your teeth—you've already encountered a biofilm.

Biofilms are communities of microorganisms that attach to a surface and surround themselves with a protective matrix. Think of it as a tiny microbial neighborhood surrounded by its own protective barrier.

And yes, microorganisms are apparently smart enough to build gated communities.

Biofilms can form on natural surfaces in the body, including the teeth and tissues, as well as on medical devices such as catheters and artificial joints. They're especially important in medicine because microorganisms living within a biofilm can behave differently from microorganisms floating freely on their own.

This can make certain biofilm-associated infections more persistent and more difficult to treat.

What Exactly Is a Biofilm?

A biofilm forms when microorganisms attach to a surface and begin creating an extracellular matrix around themselves.

That matrix can contain substances such as proteins, carbohydrates, lipids and extracellular DNA. It helps the microorganisms adhere to a surface while creating a more protected environment for the microbial community.

One of the easiest examples is dental plaque.

Biofilms can also develop on medical devices and in association with certain infections affecting different areas of the body.

But an important distinction is that having bacteria in your body doesn't automatically mean you have a problematic biofilm.

Our bodies naturally contain enormous communities of microorganisms, particularly within the digestive tract, mouth, skin and vaginal microbiome. Many of these organisms are normal—and beneficial—parts of human health.

The goal isn't to sterilize the body.

It's to maintain a healthy microbial environment and appropriately address infection when it is actually present.

Why Are Biofilms So Difficult to Treat?

This is where biofilms become particularly interesting.

Microorganisms living inside a biofilm can be more tolerant of antimicrobial treatments and immune defenses than the same microorganisms living freely.

The protective matrix can influence how antimicrobial substances penetrate the microbial community, while microorganisms deeper within the biofilm may behave differently metabolically.

In other words, treating bacteria growing freely in a laboratory dish isn't always the same as treating bacteria organized inside a mature biofilm.

This is one reason biofilms are an important area of research in chronic and recurrent infections.

Where Are Biofilms Found?

Biofilms are everywhere.

They can form in nature, in plumbing, on food-processing equipment, on your teeth and on medical devices.

In medicine, biofilms are particularly well recognized in association with:

• dental plaque and periodontal disease

• implanted medical devices

• catheters

• artificial joints

• chronic wounds

• certain respiratory infections

• some recurrent urinary infections

Biofilm formation has also been studied in other chronic and recurrent infections.

The important distinction is that a chronic symptom doesn't automatically mean a biofilm is present.

That's where proper evaluation matters.

Biofilms and Chronic or Recurrent Infections

One reason I became interested in biofilms through functional medicine is their potential role in infections that seem to keep coming back.

You treat the infection.

You feel better.

Then several weeks or months later, you're dealing with the same problem again.

There can be many reasons this happens, so I don't automatically assume biofilms are responsible. But when someone has a documented recurrent infection, biofilm formation may be one piece of the puzzle worth considering.

Rather than simply asking, “What can we take to kill this?”, I want to understand why the problem keeps returning.

That may mean looking at the organism involved, the location of the infection, microbiome health, immune function, underlying medical conditions, medications, anatomy and other factors that could contribute to recurrence.

Can You Tell If You Have Biofilms From Your Symptoms?

This is one area where you'll find a lot of questionable information online.

You may see lists claiming that headaches, anxiety, insomnia, joint pain, fatigue, cold hands and feet, hot flashes, palpitations, digestive problems and dozens of other symptoms are all “signs of biofilms.”

The problem is that these symptoms are extremely nonspecific.

There isn't a universal set of symptoms that tells me someone has a biofilm.

Instead, I look at the clinical picture and the underlying condition.

If someone has recurrent urinary tract infections, chronic dental problems, an infected medical device or another persistent infection, the conversation about biofilms is very different from assuming that fatigue or bloating automatically means hidden biofilms are causing the problem.

This is an important distinction.

What About Gut Biofilms?

This is where the functional medicine conversation gets particularly interesting—and also where we need to be careful.

The digestive tract contains an enormous microbial ecosystem. Bacteria communicate with one another, interact with the intestinal lining and exist within complex microbial communities.

Some microbial biofilms are part of normal biology, while pathogenic biofilm formation is being investigated for its potential role in certain gastrointestinal diseases.

That doesn't mean every person with bloating, constipation, diarrhea or IBS symptoms needs a “biofilm buster.”

Digestive symptoms can have many causes, including food intolerances, altered motility, constipation, infections, medications, inflammatory conditions, digestive enzyme insufficiency and changes in the gut microbiome.

Before trying to break apart a biofilm, I want to know what we're actually trying to treat.

Can You Break Down a Biofilm?

Researchers are actively studying different ways to prevent biofilm formation and disrupt established biofilms.

One compound that has received considerable attention is N-acetylcysteine, or NAC.

NAC is best known as a precursor to glutathione and as a mucolytic, meaning it helps break down mucus. Laboratory research has also found that NAC can interfere with the formation of certain bacterial biofilms and may affect established biofilms.

Clinical research is much more limited, however, and the effects appear to vary depending on the microorganism, concentration, location and treatment approach.

This is exactly why I don't think of a “biofilm buster” as a universal supplement that everyone with chronic symptoms needs.

The treatment should match the problem.

What About Natural Biofilm Support?

A number of foods, herbs and plant compounds are being studied for antimicrobial and anti-biofilm properties.

These include compounds found in foods and herbs such as:

• garlic

• oregano

• ginger

• cinnamon

• cranberries

• curcumin

That doesn't mean eating garlic for dinner is going to dismantle a chronic medical-device infection.

But these foods contain interesting phytochemicals and can absolutely be part of a nutrient-dense diet that supports overall health and a diverse microbiome.

Depending on the individual case, functional medicine protocols may also incorporate targeted supplements.

The key word there is targeted.

Should You Take a “Biofilm Buster” Before an Antimicrobial?

You'll sometimes hear that everyone should start with a biofilm disruptor before taking antimicrobial herbs or other treatments.

I don't use that as a blanket rule.

There are situations where targeting biofilm formation may make sense as part of a broader treatment strategy. There are also plenty of situations where adding multiple “biofilm busters” isn't necessary and may make a protocol unnecessarily complicated.

This is one reason I prefer sequencing functional medicine protocols according to the individual rather than handing everyone the same gut protocol.

First, determine what you're treating.

Then decide what tools actually make sense.

Supporting a Healthy Microbiome Matters Too

The goal of functional medicine shouldn't be to wage war on every microorganism in your body.

Your digestive tract, skin, mouth and reproductive tract all depend upon complex microbial ecosystems.

Beneficial microorganisms help interact with the immune system, produce important metabolites and compete with potentially harmful organisms.

So when I'm working with gut health, I don't only ask:

“What do we need to kill?”

I also ask:

“What do we need to support?”

That may include dietary diversity, adequate fiber when tolerated, digestive function, bowel regularity, sleep, blood sugar regulation and foods that help nourish a healthy microbiome.

Sometimes rebuilding the terrain is just as important as removing something we don't want there.

Dr. Stephanie's Tip: Don't assume you have biofilms simply because you have bloating, fatigue, brain fog or another chronic symptom.

Biofilms are real and medically important—but they've also become a bit of a wellness buzzword.

If recurrent infection is part of your health history, the better question is:

Why does this keep coming back?

That's where testing, medical history and the overall clinical picture become much more useful than randomly adding another supplement to your cabinet.

Your supplement cabinet probably has enough friends already.

A Functional Medicine Approach to Chronic and Recurrent Health Problems

Biofilms can be an important part of certain chronic and recurrent infections, but they're only one piece of a much larger puzzle.

At New Direction Natural Medicine in Altamonte Springs, I use functional medicine to look more closely at digestive health, the microbiome, immune function, nutrition, metabolic health and other factors that may contribute to persistent symptoms.

Depending on the individual, this may include specialized laboratory testing and a personalized nutrition and supplement plan.

Rather than assuming everyone needs a “biofilm protocol,” my goal is to understand what's actually happening and why.

Because the best protocol isn't the one with the most supplements.

It's the one that makes sense for the person sitting in front of me.

If you're dealing with persistent digestive concerns or recurrent health issues and want a more individualized approach, schedule a functional medicine consultation at New Direction Natural Medicine in Altamonte Springs, serving Orlando and the surrounding Central Florida area.
