PHYSICIAN-LED FUNCTIONAL MEDICINE
Candida
Candida is a yeast that naturally lives in the human body, including on the skin and in the mouth, vagina, and digestive tract. For most healthy individuals, its presence causes no problems. A Candida infection can develop when yeast grows excessively in a particular area and causes disease. Symptoms and appropriate treatment depend on where that infection occurs (1).
At hol+, functional care begins by determining whether Candida is actually responsible for the symptoms. Physicians consider recurrent infections in the context of medication exposure, blood sugar regulation, immune health, and other relevant factors. This approach to Candida treatment combines established medical care with a personalized evaluation of conditions that may contribute to persistent or recurring problems.
What Is Candida Overgrowth?
Candida is a group of fungi, or yeasts, that can normally live on the body without causing illness. Candidiasis is the medical term for an infection caused by Candida. Candida albicans is the most common species associated with candidiasis, although other species can also cause infection and may respond differently to treatment.
The term “Candida overgrowth” is commonly used to describe excessive growth of this yeast. Medically, however, identifying the location and type of infection matters more than applying one broad label. A positive result from a test does not necessarily establish that Candida is responsible for a person's symptoms.
A localized vaginal or oral infection differs substantially from an invasive infection involving the bloodstream or internal organs. Likewise, finding Candida in the gut does not automatically indicate a disease requiring antifungal therapy.
Types of Candida Infections and Their Symptoms
Possible intestinal fungal overgrowth
Candida may be present in the digestive tract without causing illness. Researchers have investigated small intestinal fungal overgrowth (SIFO) in people with persistent gastrointestinal symptoms. However, symptoms such as bloating and abdominal discomfort are nonspecific, and diagnostic methods remain less established than those for common localized infections (3).
Skin candidiasis
Yeast may cause an itchy, inflamed rash, often in moist skin folds. A similar-looking rash can also arise from dermatitis or other skin conditions, which makes an accurate diagnosis important.
Oral and throat candidiasis
Oral thrush can cause white patches, redness, soreness, or discomfort while eating. Esophageal candidiasis affects the swallowing tube and may cause painful or difficult swallowing. These infections deserve particular attention when someone has diabetes, takes certain medications, or has impaired immune defenses.
Invasive candidiasis
This serious condition occurs when Candida affects the blood or internal organs, most often in people with major medical risk factors, including critically ill or recently hospitalized patients. It is not the same as the loosely defined idea of "systemic Candida" sometimes used to explain chronic everyday symptoms. Suspected invasive disease requires urgent hospital-based evaluation and treatment (4).
Vaginal candidiasis
A vaginal yeast infection may cause itching, burning, soreness, redness, or changes in discharge. These Candida symptoms overlap with other causes of vaginal irritation, so examination and appropriate testing may be needed. Recurrent candidiasis of the vagina is generally defined by the CDC as three or more symptomatic episodes within one year (2).
Who May Benefit From a Candida Evaluation?
An evaluation can be helpful when an infection keeps returning, does not respond as expected to treatment, or develops in the setting of another health concern.
At hol+, physician-led assessment may be appropriate for adults experiencing:
Persistent digestive concerns where an appropriate gastrointestinal assessment has not yet identified the cause
A previous "Candida overgrowth" diagnosis based largely on symptoms or nonstandard testing
Repeated candidiasis alongside diabetes, elevated blood sugar, or medication-related risk
Oral thrush or suspected Candida after antibiotics or corticosteroid exposure
Recurrent yeast infections or ongoing vaginal irritation despite previous treatment
Patients do not need to assume Candida is behind every ongoing symptom to seek a more thorough evaluation. Fatigue or brain fog alone is not reliable evidence of Candida infection.

How We Help
Risk Factors and Predisposing Conditions We Evaluate
Recognized risk factors vary by infection site. When candidiasis recurs, hol+ looks for exposures or conditions that may increase the risk of infection (5):
Antibiotic exposure: Recent or frequent courses, especially when infections follow treatment.
Blood sugar concerns: Diabetes or elevated glucose, particularly with recurrent genital infections.
Immune health: A weakened immune system or medications that suppress immune defenses.
Medication effects: SGLT2 inhibitors, which can increase the risk of genital fungal infections (6).
Oral health: Dry mouth, dentures, or inhaled corticosteroid use.
Women's health: Pregnancy and hormonal contraceptive use.
The relationship between diabetes and yeast infections is well established, but not every recurrent infection has an identifiable trigger. Physicians investigate relevant patterns without assuming there must be a hidden underlying condition.
The hol+ Approach to Candida Care
hol+ combines conventional diagnosis with the whole-person perspective of functional medicine and holistic medicine for Candida. Before recommending a treatment plan, physicians follow a sequence grounded in the patient's symptoms and clinical findings:
Evaluate → Confirm When Indicated → Treat → Address Contributors → Monitor
- Evaluate: Identify the affected area, symptom pattern, and history of prior infections.
- Confirm when indicated: Choose site-specific examination or testing rather than assuming Candida is the cause.
- Treat: Recommend or coordinate appropriate care for the diagnosed infection.
- Address contributors: Review relevant metabolic concerns, immune health, and medication exposure.
- Monitor: Assess the response to treatment and any subsequent recurrence.
Treatment decisions reflect individual clinical findings rather than a standard Candida cleanse or supplement protocol.

What we Offer
Areas of Candida Care
The following areas help functional physicians decide which underlying conditions deserve attention. Not every patient needs evaluation or treatment across every category.
Candida and Microbiome Health
Candida and microbiome interactions are part of normal microbial ecology. Changes in microbial communities may occur after medication exposure, but a finding of gut dysbiosis is not itself proof of a Candida infection.
- Review recent exposures that may have affected local microbial balance.
- Consider the infection site rather than assuming all yeast problems originate in the gut.
- Discuss nutrition and digestive health when relevant to the patient's broader concerns.
Candida and Antibiotic Exposure
Antibiotics can alter bacterial communities that normally coexist with yeast. When symptoms develop during or after a course of treatment, the timing may help clarify the clinical picture.
- Document which antibiotics were used and when symptoms began.
- Review whether episodes repeatedly follow antimicrobial treatment.
- Consider prevention and follow-up plans for patients with established recurrence patterns.
Candida and Blood Sugar / Metabolic Health
Poorly controlled blood sugar can contribute to susceptibility to certain yeast infections. Metabolic evaluation may therefore play an important role when candidiasis occurs repeatedly or diabetes is suspected.
- Assess diabetes history and previous glucose or HbA1c results.
- Review relevant medications and possible genital fungal side effects.
- Coordinate metabolic support, including weight management when clinically appropriate, without treating body weight as the diagnosis.
Candida and Immune Function
Immune defenses help keep normally present yeasts from causing infection. For immunocompromised patients, the location and severity of symptoms may warrant closer assessment or specialist care.
- Review known immune-related diagnoses and immune-suppressing therapies.
- Consider the significance of recurrent thrush or unusually severe infections.
- Determine when additional investigation or specialist referral is needed.
Candida and Women's Health
Hormonal circumstances and vaginal health can influence susceptibility to candidiasis, particularly during pregnancy. Persistent vulvovaginal symptoms should not automatically be treated as another yeast infection.
- Review episode frequency, prior test results, and response to medication.
- Evaluate alternative causes of irritation or discharge.
- Coordinate individualized care through women's health when appropriate.
Candida and Digestive Symptoms
Candida and gut health are often discussed together, but digestive symptoms alone cannot identify intestinal Candida as their cause. A functional medicine for gut health evaluation should also consider more established gastrointestinal explanations.
- Assess symptoms in the context of digestive health and dietary tolerance.
- Consider irritable bowel syndrome (IBS), SIBO, motility concerns, or other conditions when indicated.
- Discuss intestinal permeability, sometimes called leaky gut, without equating it with proven fungal infection.
How Is Candida Diagnosed?
Candida testing depends on the suspected infection, not a standard "Candida panel." Vaginal symptoms may warrant examination and microscopy or culture to establish the diagnosis. For recurrent or complicated infections, identifying the Candida species may help guide treatment. Oral thrush is often diagnosed through examination, while painful swallowing may require evaluation for esophageal disease (2).
A positive result does not always establish infection. Finding Candida in stool, for example, does not prove it causes digestive symptoms. Commercial microbiome profiles, urine organic acid testing, and Candida antibody panels are not validated standalone tests for a generalized yeast overgrowth syndrome.
Blood glucose or HbA1c testing may be appropriate when the history suggests a metabolic contributor. Suspected invasive candidiasis requires urgent hospital-based evaluation.
Treatment options
Personalized Candida Treatment Options
At hol+, nutrition may complement antifungal treatments, particularly when blood sugar regulation is a concern. Reducing added sugars can support metabolic health, although restrictive Candida diets have not been proven to eliminate infections (8). Probiotics may be considered for broader gut-health concerns but are not established treatments for vaginal candidiasis (2).
Candidiasis treatment depends on the infection and may involve topical or oral antifungal medications. Recurrent vaginal infections sometimes require maintenance therapy (7). During pregnancy, the CDC recommends seven days of topical azole treatment rather than oral fluconazole (2).
Candida overgrowth treatment should be guided by the diagnosis rather than a standard diet or supplement protocol.

Candida functional care visits are available in Brookhaven (Atlanta), Johns Creek, New York City, and Los Angeles, or via virtual appointments nationwide. Virtual patients receive lab orders as part of their treatment plan, which can be performed at any testing facility or doctor's office of their choice.
Benefits of Treatment
Potential Benefits of an Individualized Evaluation
An appropriate functional medicine diagnosis can help patients avoid repeated self-treatment for symptoms caused by a different medical condition. For documented infections, selected therapy may relieve discomfort and improve recovery. Reviewing a recurrence pattern can also uncover modifiable contributors that deserve attention independently of Candida.
Patients can better understand previous test results and develop an informed holistic follow-up plan. Any contributing metabolic concerns can also be addressed during a functional medicine exam. These are realistic goals rather than promises that comprehensive care will eliminate every future infection.
Risks & Limitations
Candida may be present without causing illness, so a positive test must be interpreted in context. Vaginal irritation may have causes other than candidiasis, including contact reactions or allergies. Likewise, persistent fatigue should not be attributed automatically to gut Candida. Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a distinct condition requiring its own evaluation.
Repeated self-treatment can delay diagnosis and cause medication side effects or interactions. Some Candida species resist commonly used antifungal drugs, and pregnancy affects which medicines are appropriate.
When to Seek Medical Attention
Arrange a physician evaluation for persistent or recurrent symptoms, especially during pregnancy or with impaired immune defenses. Seek urgent care for fever or chills in someone with major risk factors for invasive infection, or swallowing difficulty that prevents adequate hydration. Suspected invasive candidiasis requires hospital-level care.
What to Expect as a Patient
What to Expect as a Patient at hol+
The physician reviews the symptom history and timing of previous episodes. Earlier diagnoses and test results help clarify if Candida has actually been established as the cause.
Examination and testing are selected according to symptoms and the affected area. Metabolic or other laboratory studies may be appropriate if the history suggests an underlying contributor.
When infection is identified, the physician discusses established treatment options and relevant health considerations. Other causes of symptoms are addressed or referred for further evaluation when needed.
Follow-up considers symptom response, treatment tolerance, and any new episodes. Care can be adjusted if the diagnosis or recurrence pattern changes. When appropriate, telehealth appointments allow patients to discuss their progress and receive ongoing guidance without an additional in-person visit.
