Yeast overgrowth (often referred to as “Candida”) occurs when fungal species grow beyond healthy levels in the gut.
It often appears alongside dysbiosis, SIBO, or post-antibiotic changes.

Why Yeast Overgrowth Occurs

Common contributors include:

• antibiotics

• high sugar intake during stressful periods

• dysbiosis

• low stomach acid

• SIBO

• chronic stress

• long-term PPI use

• impaired immune function

• post-infectious changes

Yeast overgrowth is rarely the root cause — it’s usually a downstream effect.

Common Symptoms

Digestive symptoms:

• bloating

• gas

• nausea

• food sensitivities

• constipation or diarrhoea

Whole-body symptoms:

• fatigue

• brain fog

• recurrent thrush

• skin issues

• sugar cravings

• histamine symptoms

• worsened PMS

Symptoms fluctuate — often worse after sugar, alcohol, or stress.

Connections With Other Gut Conditions

Yeast overgrowth commonly coexists with:

• SIBO

• dysbiosis

• leaky gut

• low stomach acid

• post-antibiotic shifts

• histamine intolerance

Supporting the underlying terrain is key.

Stress & Yeast

Stress alters gut immunity and microbiome balance, making fungal overgrowth more likely.

This is why flare-ups often occur during emotionally demanding periods.

Testing Options

A stool test can identify:

• candida species

• fungal overgrowth

• inflammation

• digestive enzyme function

• short-chain fatty acids

Breath tests do not detect yeast — only bacteria.

Supporting Yeast Overgrowth Long-Term

True support includes:

• balancing the microbiome

• supporting stomach acid and enzymes

• restoring gut immunity

• reducing inflammation

• supporting nervous-system regulation

• addressing coexisting patterns like SIBO or dysbiosis

• nutritional strategies that stabilise blood sugar

Antifungals alone rarely solve the underlying issue — environment matters.

Yeast overgrowth improves most when the gut environment is strengthened — not just when symptoms are treated
