Health Scan Has Key Benefits

This health scan is one of the tools we use in clinic to monitor some important health markers. It also helps you to understand where the stress points are. When you make lifestyle changes you can see how they affect your health. The effect of medicines can also be checked.


The following pictures represent some of the charts and models you will see when you have your health scan.

Health Tests

Body composition indicators such as fat free mass, fat mass, hydration and cellular density.

Framingham scale for cardiac and metabolic health.

Potential inflammation in organ tissue.

Indication of possible lymphatic congestion and stress in the nervous system.

3D model of brain showing areas of stress in the frontal lobes and limbic system.

The Esteck Health Scan was developed by scientists and technology experts. They envisioned a system which could be shared by Doctors, Specialists and other health professionals. The purpose is to detect health risks earlier and monitor the effects of lifestyle and medication.
Stress, poor diet, inflammation, unhealthy microbiome and obesity contribute to symptoms of anxiety, pain and fatigue. After many years chronic health problems develop. Most of these can be prevented by healthy lifestyle changes.

How Does it Measure

How does it scan?

The device is similar to an electroencephalogram (EEG) or electrocardiogram (ECG). It is a combination of non-invasive bioimpedance sensors that send a slight electrical impulse through the interstitial fluid of the body. The device measures the ease or difficulty with which the current travels. This may be affected by acidity, cell size and density, water content etc.

Pulse oximetry is a noninvasive method for monitoring a person’s oxygen saturation (SO2).

Impedance plethysmography, measures small changes in electrical resistance of regions of the body. These measurements reflect blood volume changes.

One of the most sensitive markers for emotional arousal is galvanic skin response, also referred to as  electro-dermal activity (EDA). EDA determines the amount of sweat secretion from sweat glands. The number of sweat glands varies across the human body, being highest in hand and foot regions (200–600 sweat glands per cm2).


After the scan you can see an overview of health through 3D coloured body models and charts. The data looks at patterns that show a match similar to controls collected over time, stored in the database. The accuracy is impressive.

What Is Measured?

• Cardiac Power and Output – this shows how “hard” your heart works with each stroke, and how much blood is moved with each stroke.
• Vascular and Arterial Resistance and Stiffness – measures the health and elasticity of your veins and arteries.
• Oxygen Uptake, Saturation and Delivery – tells us how well your body is using and absorbing oxygen.
• Autonomic Nervous System – gives us insight into potential problems related to how your body is adapting and healing. The autonomic nervous system regulates involuntary functions like bowel motility, perspiration and digestion.
• Body Composition – portrays the percentage of body fat and lean muscle tissue as well as both extra cellular and intra cellular water. This is a great way to monitor healthy weight loss.
• Risk of Diabetes – Insulin resistance and damage to beta cells can begin as early as 10 years prior to the standard detection of diabetes. Insulin Resistance is also involved in metabolic syndrome, obesity and inflammation.

Heart rate variability (HRV), is the variation in the intervals between heart beats. If your heart beats like a metronome, with intervals of identical length between each pulse, you have low heart rate variability; this is “bad.” If your heart beats follow a more fractal pattern, with beat intervals of varying length, you have high heart rate variability; this is “good.”

A healthy heart pumps as needed. It responds to the demands of the organism; it doesn’t follow rigid intervals.

In general, a high HRV indicates dominance of the parasympathetic response, the side of the autonomic nervous system that promotes relaxation, digestion, sleep, and recovery. The parasympathetic system is also known as the “feed and breed” or “rest and digest” system.

A low HRV indicates dominance of the sympathetic response, the fight or flight side of the nervous system associated with stress, overtraining, and inflammation.

How are people actually using HRV today?

  • Track progress and guide treatment plans
  • Improve resilience and adaptability
  • Customize training and optimize recovery time
  • Personalize nutrition, sleep and exercise protocols
  • Provide early warning signs for changes in health, overtraining or maladaptation
  • Re-balance the nervous system with live biofeedback
  • Objectively understand motivation and willpower
  • Identify risk of morbidity and mortality

Humans like to visualise, so the models used in the health scan help people to relate to what’s going on in their body. Many times clients get that “aha” moment when they recognise symptoms they’ve been experiencing.

We find that when people make the mental connection to the underlying cause then they’re in a better place to make healthy changes. 

The information is not intended to diagnose disease but is a very useful tool to monitor health markers when combined with other observations and tests.
