In Traditional Chinese Medicine (TCM), a comprehensive diagnosis is central to the process before any treatment can begin. The aim is to understand the causes of symptoms and identify individual interrelationships. This forms the basis for a holistic treatment plan tailored to your needs.
What makes TCM diagnosis unique?
Traditional Chinese Medicine regards health as the harmonious interplay of various physical and functional processes. Symptoms are not viewed in isolation, but are analysed in the context of the whole organism.
Whilst modern medicine often focuses on individual organs, laboratory results or specific diagnoses, TCM also takes into account the person’s everyday life and lifestyle.
Typical questions include:
- How is the quality of your sleep?
- How is your digestion?
- How high is your energy level throughout the day?
- How do you react to stress?
- Do you tend to feel cold or warm?
- Are there any recurring patterns to your symptoms?
This information helps to identify individual connections and gain a more comprehensive picture.
The four pillars of TCM diagnosis
Diagnosis in Traditional Chinese Medicine is based on several complementary methods. It is only through their combined application that a complete picture of an individual’s health situation emerges.
Tongue diagnosis
Tongue diagnosis is regarded as one of the key diagnostic tools in TCM. The tongue is viewed as a kind of ‘mirror’ of the body’s internal processes, as it is closely linked to various functional systems.
During the examination, the colour, shape, mobility and texture of the tongue are assessed, amongst other things. The tongue coating also plays an important role. Changes can indicate specific imbalances or functional disorders.
For example, a pale tongue may indicate a deficiency, whilst a reddened tongue may indicate internal heat processes. The thickness and colour of the coating, as well as any swelling or indentations at the edges of the tongue, are also taken into account in the assessment.
The detailed medical history interview
Every TCM diagnosis begins with a consultation. This forms the most important basis for understanding the interrelationship between symptoms. It is not just about the current symptom, but about the person as a whole and their life circumstances.
Typical topics include sleep, digestion, energy levels throughout the day, stress levels, emotions, and sensitivity to cold or heat. Previous illnesses and long-standing patterns also play an important role.
What is particularly valuable is that even seemingly trivial details can be diagnostically relevant in TCM. This often reveals connections that are not immediately apparent in everyday life but are crucial to understanding the symptoms.

Observation
First impressions are formed as soon as one enters the room, and these are taken into account when making a diagnosis. In TCM, a person’s overall appearance is taken into consideration – not as a judgement, but as an additional source of information.
This includes, amongst other things, posture, movement patterns, skin condition, voice and the quality of breathing. A person’s general demeanour and energy levels can also provide clues as to their functional state.
These observations are not considered in isolation, but always in conjunction with the other diagnostic methods. They help to complete the overall picture and to better understand the individual’s situation.
Pulse diagnosis
Pulse diagnosis is another important diagnostic tool in TCM. It involves palpating the pulse at three different positions on each wrist. The focus is not only on the pulse rate and rhythm, but above all on the qualitative characteristics of the pulse.
Among other things, the strength, tension, depth, speed and regularity of the pulse are assessed. In TCM, these characteristics are associated with specific functional patterns. For example, a weak pulse may indicate a deficiency of energy, whilst a tense pulse is associated with stress or internal tension.
Pulse diagnosis requires a great deal of experience and a keen sense of touch. The examination is painless and can be repeated throughout the course of treatment to identify any changes.

Why an accurate diagnosis is so important
A key principle of Traditional Chinese Medicine is that not every person with the same symptoms requires the same treatment. For example, two people may both suffer from headaches, yet the underlying causes may differ. For one person, stress and tension may be the main factors, whilst for the other it may be exhaustion or digestive problems. Read more about the most common symptoms on our overview page. TCM diagnostics make it possible to identify these individual differences and tailor the treatment accordingly.
Traditional Chinese Medicine is not intended as a substitute for conventional medical assessments, but rather as a complementary approach. Thanks to our practice’s affiliation with Zollikerberg Hospital, patients benefit from a professional medical environment and holistic care.
