Scientific Basis

The Vega machine is based on principles of electrodermal biofeedback, originally developed from the work of Dr Reinhold Voll in Germany. It measures changes in the skin's electrical conductance at specific acupuncture points, which are known to have lower electrical resistance than surrounding tissue.

These points are functionally connected, through the autonomic nervous system, to internal organs and regulatory systems. Physiological stress — including stress triggered by problematic foods — can alter autonomic nervous system activity. This, in turn, produces measurable changes in skin conductance. The Vega system detects these changes in real time.

How the Test Works

During the assessment:

• A handheld electrode is placed in the patient's hand.
• A probe is applied to specific acupuncture points on the hands and feet.
• The Vega device sends an extremely low-voltage electrical signal through the body (far below perceptible or harmful levels).
• When a test substance (for example, wheat, dairy, or eggs) is introduced into the circuit, the machine detects whether the body's electrical response remains stable or becomes disrupted.

This response reflects functional disturbance, not structural disease — meaning it identifies physiological stress patterns before pathology develops.

What the Test Identifies

Vega food intolerance testing is used to assess:

• Delayed food reactions
• Digestive stress responses
• Functional disturbances in gut regulation
• Autonomic nervous system reactivity to foods

It is particularly useful for patients with:

• Bloating, IBS-type symptoms
• Migraines
• Chronic fatigue
• Skin conditions
• Joint pain
• Brain fog

Where standard allergy tests are often normal.

Advantages of Vega Testing

• Non-invasive and painless
• No blood samples
• No need for food elimination prior to testing
• Immediate results in clinic
• Suitable for adults and children

It provides a functional assessment of reactivity, complementing conventional medical investigations.

Clinical Interpretation

Results are not viewed in isolation. They are interpreted alongside:

• Symptom history
• Diet patterns
• Medical background
• Nutritional status

The findings guide:

• Personalised dietary planning
• Targeted gut support
• Nutritional therapy programmes

This integrative approach improves accuracy and clinical relevance.
