Gastrointestinal Yeast Overgrowth

Candida albicans is a normal gut commensal but in certain circumstances candida and other yeasts can proliferate and cause major problems. In current main-stream medicine we only treat gut candida when it is a potential source for vaginal or systemic candida; the GI yeast overgrowth syndrome is not yet recognised. Of 284 Gut Fermentation Profiles (Biolab) performed in an eight year period, 56% were positive for intestinal yeast overgrowth.

The effects of chronic gut candidiasis include:

In GI yeast overgrowth a strong fungal sensitivity (yeast, mould and mushroom/toadstool) frequently develops. For this reason major improvement does not occur unless the patient avoids:

1) ingested fungi

2) sugar (as this stimulates the growth of GI tract yeasts)

If chronic GI yeast overgrowth is a major problem in a patient, treatment produces a very dramatic multi-system improvement in their symptomatology, health and well-being. If the predisposing factors are not identified and dealt with adequately, long term maintenance treatment will be required.

The following symptoms may indicate chronic GI yeast overgrowth:

A history of candida elsewhere - oral, vaginal, etc

Alcohol intolerance


Cataneous tinea

Chemical sensitivities - petrol, diesel, paint fumes, perfumes, etc.

Cravings for sugars, refined carbohydrates, yeasted foods, incl. alcohol


Fatigue, lethargy, "woolly head"

Fluid retention

Headaches, migraines

History of repeated or long term use of antibiotics

Irritability, mood swings, depression

Irritable Bowel Syndrome

Mould sensitivity- symptoms worse in damp environments


Onset or worsening in symptoms after antibiotics

Onset or worsening in symptoms during or soon after pregnancy

Onset or worsening in symptoms on oral contraceptives

Pruritis ani

Recurrent sterile UTI's

Seborrhoeic eczema

Sexual partner has had candida problems

Symptoms worse in damp environmentsUrticariaWorsening of symptoms after eating sugars, refined carbohydrates, yeasted foods, mushrooms.


Some Causes of Chronic GI Yeast Overgrowth:



Recommended treatments:

Exspore & Candaway used together, one of each tds with each meal for 4-6 weeks

Oregano complex & Bioacidophilus, two with evening meal for 6 weeks
