Ear Infections and GAPS: Causes, Glue Ear, and the Diet Approach

GAPS separates glue ear from an active ear infection. Glue ear is mucus trapped in the middle ear after inflammation closes the Eustachian tube. It can impair hearing without the pain and fever of an active infection. An infection may then arrive in that trapped mucus, bringing earache and a high temperature. In the GAPS account, the long-term work is changing the abnormal microbial flora in the nose and throat while following the full Nutritional Protocol.^[1][2]

Here I explain how the GAPS books connect the microbial flora, inflammation and drainage, and why they discuss recurring infections alongside diet and dairy. For practical food choices, use my ear-infection food guide. My ear-symptom checklist helps you keep the hearing changes and painful episodes in a dated record.

Why Recurring Ear Problems Matter

The expanded Gut and Psychology Syndrome book reports that ear infections account for more than one-third of doctor visits, that about two-thirds of children in Western countries have at least one ear infection each year and that one-third of those children have more than four in a year. Those numbers are the book’s cited context for why the chapter treats recurring ear infections and glue ear as a widespread pattern.^[2]

How the Middle Ear Is Protected

The middle ear is a small, air-filled space behind the eardrum. It connects to the back of the nose and throat through the Eustachian tube. The tube helps equalize pressure and is protected at its throat opening by immune tissue called the tubal tonsils.^[2]

The Eustachian tube also has ciliated epithelium, a lining covered with tiny hairs that point away from the middle ear. Mucus moves in the same direction toward the throat. Together, the moving mucus, lymph follicles in the tube and tubal tonsils form the protective system the expanded book describes.^[2]

Tubal tonsils sit around the openings of the Eustachian tubes. Adenoids are nearby immune tissue, but they are a different structure. The GAPS FAQ about swollen adenoids is covered below.^[2][7]

Glue Ear and Active Infection Are Not the Same

The distinction matters because a child can have reduced hearing while appearing free of an acute infection. The expanded book connects persistent middle-ear mucus with impaired hearing, learning difficulty and speech delay. Those are consequences it places downstream of glue ear, not proof that every speech or learning concern comes from the ear.^[2]

How GAPS Describes Early Microbial Development

In Gut and Physiology Syndrome (2020), Campbell-McBride describes gut-flora development during pregnancy, with further contributions during birth, breastfeeding and later contact. Her expanded ear chapter focuses on the microbial flora in the nose and throat and on the middle ear’s drainage.^[3][2]

Gut flora and the microbes in the nose and throat live in different parts of the body. The GAPS approach combines the wider Nutritional Protocol with a local probiotic routine for the throat, described below.^[1]

How GAPS Explains the Recurring Cycle

1. Abnormal flora lives in the nose and throat.
2. Chronic inflammation affects the Eustachian tube and the tubal tonsils at its opening.
3. The opening closes and mucus cannot drain.
4. The middle ear fills with mucus, creating glue ear and reducing hearing.
5. An infection may enter the mucus-filled space, producing earache and fever.
6. An antibiotic may remove the acute organism without clearing the trapped mucus or correcting the flora.
7. The book says the remaining mucus and altered flora prepare the setting for another infection.

For the longer-term work, Campbell-McBride recommends the full GAPS Nutritional Protocol. Her 2020 ear-infections section also describes finishing meals with homemade kefir and using kefir or probiotic powder at bedtime to support the throat’s flora.^[1]

Why the Books Connect Antibiotics With Recurrence

The expanded ear chapter says an antibiotic can clear one acute infection while leaving middle-ear mucus in place. It also says antibiotics further alter the microbial flora of the nose and throat. When the medicine is given as a children’s syrup, the same passage separately objects to the sugar and starch in the syrup because the book says they feed organisms in the throat.^[2]

The antibiotic chapter adds class-specific detail:

• Penicillins are described as damaging Lactobacilli and Bifidobacteria while promoting pathogenic Proteobacteria, Streptococci and Staphylococci.^[4]
• Tetracyclines are described as altering proteins in the gut lining while promoting Candida, Staphylococci and Clostridia, with the chapter emphasizing the damage of long courses.^[4]
• Aminoglycosides and macrolides are described as particularly damaging to beneficial E. coli and Enterococci; the chapter says longer use may remove them from the digestive tract.^[4]

The book says combinations, oral antibiotics and long-term low-dose use cause more damage than a single drug or shorter exposure. It specifically names chronic middle-ear infection as one setting in which prolonged low doses may be used.^[4]

It also gives different recovery windows after even a short, low-dose course: one to two weeks for physiological E. coli, two to three weeks for Bifidobacteria and Veillonella and one month for Bacteroides and Peptostreptococci. Those are source-specific microbial examples, not a promise that the whole microbiome is restored on a fixed date.^[4]

How Ear Tubes Fit the GAPS Discussion

The expanded chapter describes grommets as small tubes placed through the eardrum so mucus can drain. It calls that a symptomatic measure because the tube provides another exit for mucus while the source’s underlying flora, inflammation and blocked natural drainage remain.^[2]

Where Food Allergy and Dairy Fit

The expanded ear chapter names food allergy, especially cow’s-milk allergy, as another contributor. Alongside its general removal of sugar, milk and processed carbohydrates, it recommends removing any food the child may be reacting to while working on gut flora and immune balance.^[2]

Her 2020 recommendation for homemade kefir belongs alongside the GAPS dairy-introduction guidance. Ordinary drinking milk and properly fermented kefir are different preparations, and a specific dairy reaction still matters. My ear-infection food guide explains which dairy steps apply and how tolerated fermented dairy fits.

Breastfeeding and the Developing Gut Flora

Campbell-McBride describes breast milk as both nourishment and a source of microbes for the developing gut flora. In her 2020 account, development continues through pregnancy, birth, breastfeeding and later contact. For your notes, record the actual feeding history alongside when ear and digestive symptoms began.^[3]

Fever and Ear Pain: When to Get Help

The expanded ear chapter reports comparison studies with similar courses with and without antibiotics. It also says antibiotics may be necessary when pain and fever have not settled after two to three days.^[2] Keep that exception with the book’s wider discussion of recurring infections.

In “Bless the Fever!,” Campbell-McBride describes fever as part of the immune response. She also says serious infections such as meningitis require medical treatment.^[5] Long-term food and flora work is a separate question from getting help for a child who is acutely unwell.

For medicine, use the advice given for your child’s age, weight and health history. Do not give a child aspirin for fever unless their doctor specifically instructs it; aspirin is associated with Reye’s syndrome.^[7] The older GAPS chapter also says a child with a rare genetic condition or impaired liver or kidney function needs a doctor’s advice before any medicine.^[2]

Seek medical care for worsening ear symptoms, drainage, hearing loss, a temperature of 39°C (102.2°F) or higher, or symptoms continuing beyond two to three days. A baby under three months with a temperature of 38°C (100.4°F) or higher needs medical advice right away. A clinician may recommend observation for a mild infection, but severe or worsening symptoms need assessment sooner.^[9]

If a seizure lasts longer than five minutes, or your child is not recovering promptly, call 911. A first seizure needs immediate medical attention. Keep the child safe from injury, do not restrain them and do not put anything in their mouth. Fever medicines may help discomfort, but they do not prevent febrile seizures.^[8]

What GAPS Says About Swollen Adenoids

The GAPS FAQ includes a separate question about swollen adenoids appearing after a child started GAPS. Campbell-McBride says it is possible that the immune system is restructuring and the adenoids became active. Her response is probiotic powder on the tongue between meals and at bedtime, a nightly salt-water nose rinse and speaking with an experienced homeopath.^[6]

Swollen adenoids and the tubal tonsils at the Eustachian-tube openings are different structures. Keep an identified adenoid problem in your notes alongside the ear symptoms, rather than treating the two names as interchangeable.

The Long-Term GAPS Approach

Across both books, the longer-term approach is to follow the GAPS Nutritional Protocol, remove the foods the ear chapter identifies, and support beneficial flora with tolerated fermented foods or a probiotic. Homemade kefir has a specific place in the 2020 throat routine.^[1]

Use the GAPS Diet for Ear Infections: What to Eat and Avoid for the diet, fermented-food and dairy details. Use the Ear Infection Symptoms Checklist: Glue Ear and Recurring Patterns to record glue-ear, acute and recurring signs without treating a checklist as a diagnosis.

Frequently Asked Questions

Can Glue Ear Exist Without an Active Infection?

Yes. Glue ear is retained fluid in the middle ear, and it may affect hearing between painful infections. An infection can develop while that fluid is present.^[2]

What Does GAPS Say About Early Gut Flora?

Campbell-McBride’s 2020 book describes gut-flora development during pregnancy, followed by contributions during birth, breastfeeding and later contact. That is her account of the gut’s development; the ear chapter separately discusses flora in the nose and throat.^[3]

Does GAPS Say Antibiotics Are Never Used for Ear Infections?

No. The expanded ear chapter criticizes routine antibiotic use and explains why it says the cycle recurs, but it also says antibiotics may be necessary when pain and fever have not subsided after two to three days.^[2]

Does the Ear Entry Ban All Dairy?

The expanded chapter removes sugar, milk and processed carbohydrates, then separately discusses suspected food allergies. The 2020 book specifically includes homemade kefir. That is why ordinary drinking milk, a particular dairy allergy and introduced fermented dairy need to be considered separately.

Choose the Guide You Need

Start with what you can observe: hearing changes between episodes, current ear pain or fever, and how often symptoms return. Note any diagnosis or middle-ear fluid already identified. Then use my ear-symptom checklist to organize the details and my food guide for the diet questions.
