Quick answers

What is fatigue and brain fog?

Fatigue and brain fog can affect your energy, focus, memory, and ability to function day to day.
For some people the problem is temporary, but for others it becomes ongoing and difficult to explain.

Symptoms may be linked to:

  • Stress or burnout
  • Hormone imbalance
  • Nutrient deficiencies
  • Poor sleep
  • Blood sugar problems
  • Gut health issues
  • Thyroid or metabolic problems

Often more than one factor is involved.

Common symptoms

People often seek support when they experience:

  • Constant tiredness
  • Poor concentration or memory
  • Feeling mentally slow or foggy
  • Low motivation or overwhelm
  • Energy crashes during the day
  • Sugar cravings
  • Poor sleep
  • Hormone-related fatigue
  • Fatigue after illness or stress

How nutrition support can help

Targeted nutrition and lifestyle support may help improve:

  • Energy production
  • Blood sugar stability
  • Hormone balance
  • Nutrient levels
  • Gut health
  • Sleep quality
  • Stress resilience

Support is personalised rather than based on a generic diet.

When to see your GP

Speak to your GP if you have:

  • Severe or worsening fatigue
  • Unexplained weight change
  • Persistent low mood
  • Irregular periods
  • Thyroid symptoms
  • Fatigue after infection or illness

We often work alongside your GP where needed.

How we support fatigue & brain fog

Fatigue rarely has a single cause. Our approach focuses on understanding what is happening in your body and building a plan that supports recovery over time.

We usually look at several areas.

1. Energy & blood sugar regulation

Unstable blood sugar can cause crashes, cravings, and poor concentration.
We work on meal structure, nutrient balance, and eating patterns to support steady energy.

2. Nutrient status & diet quality

Low levels of iron, B12, vitamin D, magnesium, iodine, or protein can contribute to fatigue.
We review diet in detail and make targeted changes.

3. Hormone balance

Fatigue is often linked to hormone changes, including:

  • Thyroid problems
  • Perimenopause or menopause
  • PCOS
  • Chronic stress

4. Gut health & inflammation

Digestive issues, food triggers, or inflammation can affect both physical and mental energy.

5. Stress, sleep & nervous system

Many people with fatigue have been under long-term stress.
We work on sleep, recovery, and supporting the nervous system.

6. Functional testing (when needed)

In more complex cases we may consider testing to guide treatment.
