Reasons for fatigue

What is it?

Whilst it is normal for many of us to feel fatigued from time to time, more chronic fatigue may be a sign of an underlying health condition. Fatigue may vary from physical tiredness, poor concentration or even brain fog. In some cases, fatigue can be linked to metabolic dysfunction or nutrient deficiencies.

Symptoms and causes

Metabolism is the process by which the body converts food into energy. When the body’s metabolism is functioning properly, it is able to break down food into glucose, which is then used by the body’s cells as a source of energy. However, when there is a problem with a person’s metabolism, it may not be able to properly convert food into energy, leading to symptoms like fatigue. This may present with physical tiredness, poor concentration or brain fog.

There are several metabolic dysfunctions that can contribute to fatigue. For example, insulin resistance is a condition in which the body is unable to properly respond to insulin – a hormone that regulates blood sugar levels. Insulin resistance can lead to high blood sugar levels and a decreased ability to convert glucose into energy, both of which can contribute to feelings of fatigue.

Another potential cause of fatigue is mitochondrial dysfunction, which refers to problems with the mitochondria – cells that are responsible for generating energy. When the mitochondria are not functioning properly, cells in the body may not be able to produce enough energy to meet the body’s needs, leading to fatigue. Other rare causes of fatigue include hormone deficiencies, muscle diseases or even sleep disorders. We work closely with you to identify the underlying cause of fatigue specific to you.


We can help address these underlying metabolic dysfunctions and create a treatment plan to improve overall health and alleviate fatigue. This may involve changes to your diet and lifestyle, as well as targeted supplements and medications to support metabolic function.

For example, we may recommend a diet to help improve insulin sensitivity and blood sugar control. We may also recommend supplements that can help support mitochondrial function and improve energy production.

In addition to these interventions, we may also use advanced testing to identify underlying metabolic dysfunctions and track progress over time. This may include tests like comprehensive metabolic panels, insulin sensitivity tests and mitochondrial function tests.

Personalised treatment plan

Through personalised treatment plans, we aim to reduce fatigue associated with metabolic dysfunction. By identifying and addressing the root causes, we can offer an effective approach to managing this common health concern.
