Do you constantly feel tired, even after a good night’s sleep?

Fatigue is one of the most common reasons people seek medical advice. While busy lifestyles, stress and poor sleep can all contribute, persistent tiredness may sometimes indicate an underlying health issue that deserves further investigation.

Blood testing can provide valuable insights into your health and help identify common causes of low energy, poor concentration and ongoing fatigue.

When Is Tiredness More Than Just Being Busy?

Everyone feels tired occasionally. However, you may want to consider further investigation if:

• Your fatigue lasts for several weeks
• You wake up feeling unrefreshed
• Your energy levels continue to decline
• You struggle to concentrate
• Daily activities feel more difficult than usual
• You experience additional symptoms such as hair loss, dizziness or weight changes

Iron Deficiency and Low Ferritin

One of the most common causes of fatigue is iron deficiency.

Iron helps your body produce haemoglobin, which carries oxygen around the body. When iron stores become low, you may experience:

• Tiredness
• Shortness of breath
• Poor concentration
• Headaches
• Dizziness

A ferritin blood test can help assess your body’s iron stores and may identify deficiency before anaemia develops.

Vitamin D Deficiency

Vitamin D deficiency is extremely common in the UK.

Low vitamin D levels may contribute to:

• Fatigue
• Muscle aches
• Low mood
• Frequent infections
• Reduced energy levels

Many people are unaware they have low vitamin D until tested.

Vitamin B12 Deficiency

Vitamin B12 plays a vital role in energy production and nervous system function.

Symptoms of deficiency may include:

• Fatigue
• Brain fog
• Poor memory
• Tingling sensations
• Weakness

Vegetarians, vegans and older adults may be at increased risk.

Thyroid Problems

The thyroid gland regulates metabolism.

An underactive thyroid can cause:

• Persistent tiredness
• Weight gain
• Feeling cold
• Dry skin
• Hair thinning

Simple blood tests can assess thyroid function and identify potential problems.

Blood Sugar and Diabetes

High blood sugar levels may also contribute to fatigue.

Symptoms can include:

• Increased thirst
• Frequent urination
• Blurred vision
• Low energy

HbA1c testing can help assess average blood glucose levels over the previous few months.

Inflammation and General Health

Sometimes fatigue may be associated with inflammation, infection or other medical conditions.

Additional tests may include:

• Full Blood Count
• CRP
• Kidney Function
• Liver Function

These can provide a broader picture of your overall health.

What Blood Tests Should You Consider?

Many patients choose a comprehensive health screen that includes:

• Full Blood Count
• Ferritin
• Iron Studies
• Vitamin D
• Vitamin B12
• HbA1c
• Thyroid Function
• Kidney Function
• Liver Function

This can help identify several common causes of fatigue in a single appointment.
