Some people also have weight gain, central weight gain, fatigue or post-meal drowsiness. Others may notice mild dry mouth or metabolic-related discomfort, but symptoms are often subtle and easily overlooked.
When blood glucose remains in a higher-than-normal range over time and is accompanied by metabolic changes, clinical assessment is needed to determine whether this is prediabetes, meaning an early stage of impaired metabolic regulation.
Prediabetes refers to a state where blood glucose is above the normal range, but has not yet reached the diagnostic threshold for diabetes.
Common diagnostic indicators include:
Key features of this stage include:
Without timely intervention, some people may gradually progress to type 2 diabetes.
The main aim in prediabetes management is to reduce the risk of progression and improve metabolic stability.
This includes dietary adjustment, regular exercise and weight management.
Weight reduction and increased physical activity can help improve how efficiently the body uses glucose.
Ongoing monitoring of blood glucose and HbA1c helps track changes over time.
For people with obesity or clear metabolic syndrome features, a doctor may recommend medication as part of management.
Clinical focus: there is still meaningful room for improvement at this stage, and early intervention can significantly reduce the likelihood of developing diabetes.
In Chinese Medicine, prediabetes may be understood as an early stage before a full wasting-thirst pattern develops. It reflects the early onset of disordered Qi movement and metabolic imbalance.
Common underlying patterns include:
The body becomes less efficient at transforming and distributing nutrients and fluids, which affects metabolic stability.
Qi deficiency may lead to low energy, reduced functional drive and fatigue, while Yin deficiency may present with internal heat signs such as dry mouth or a tendency towards overactive metabolism.
Dampness and turbidity may build up internally, affecting metabolism and body weight regulation.
When overall body rhythm and Qi movement become less smooth, blood glucose regulation may become less stable.
Overall, this can be understood as Spleen deficiency as the foundation, Qi-Yin imbalance as the main presentation, and phlegm-dampness as an important interfering factor. The focus of Chinese Medicine support is early regulation of metabolic rhythm and constitutional balance.
Assessment considers blood glucose results, body build, fatigue level, diet and daily routine to identify the main issue.
Common Chinese Medicine patterns include:
The core of pattern assessment is to determine whether the main issue is reduced transformation and metabolic efficiency, or whether phlegm-dampness and metabolic burden are more dominant.
For prediabetes, the treatment focus is metabolic rhythm regulation together with constitutional support. The priority is early intervention and long-term stability.
Treatment focuses may include:
Supporting more efficient transformation of food and better use of energy.
Helping improve fatigue and the body’s internal regulatory capacity.
Helping reduce metabolic burden and support better overall balance.
This includes support around sleep, diet, exercise and daily routine.
Depending on the individual situation, treatment may include Chinese herbal medicine, acupuncture and lifestyle advice. This should be coordinated with blood glucose monitoring and medical guidance.
Early assessment and support may be considered if any of the following are present:
The key clinical question is whether the person has entered a stage of metabolic imbalance that still has good scope for adjustment.
However, specialist medical care should be prioritised if any of the following occur:
