Understanding Tiredness & Fatigue: Causes, Types, and When to Seek Medical Help

Understanding Tiredness & Fatigue

What Are Tiredness and Fatigue?

Tiredness and fatigue are common health conditions that describe a persistent feeling of physical or mental exhaustion. While it's normal to feel tired occasionally—especially after exertion or lack of sleep—chronic or unexplained fatigue can interfere with daily life and may signal an underlying medical issue. Fatigue affects your energy levels, concentration, motivation, and overall wellbeing, and should not be ignored if it persists.

Common Symptoms of Tiredness and Fatigue

Fatigue can present with a wide range of physical and emotional symptoms, including:

Constant tiredness or sleepiness, even after rest

Difficulty concentrating or "brain fog"

Low motivation or lack of energy

Headaches or muscle aches

Mood swings, irritability, or low mood

Slower reaction times or reduced productivity

Trouble sleeping (insomnia) or unrefreshing sleep

Increased sensitivity to stress

These symptoms can gradually develop or appear suddenly, depending on the cause.

Causes of Tiredness and Fatigue

There are many potential causes of ongoing fatigue, which may be:

Lifestyle-related:

Poor sleep habits or insomnia

Sedentary lifestyle

Poor diet or dehydration

Excessive alcohol, caffeine, or drug use

Stress or emotional burnout

Medical:

Anaemia – low iron levels affecting oxygen supply to the body

Thyroid disorders – such as hypothyroidism

Diabetes – due to fluctuating blood sugar levels

Sleep apnoea – disrupted breathing during sleep

Chronic fatigue syndrome (CFS/ME)

Heart disease or chronic infections

Menopause or hormonal imbalances

Psychological:

Depression or anxiety

Grief or trauma

Work-related stress or mental overload

A medical evaluation can help identify the exact cause and guide appropriate treatment.

When to See a Doctor

You should seek professional help if:

Fatigue has lasted more than two weeks without improvement

It interferes with your work, relationships, or daily activities

You struggle to concentrate, stay awake, or function normally

You experience unexplained weight loss, low mood, or frequent infections

You snore heavily or wake up feeling unrefreshed

You have other ongoing health conditions that could be linked

Chronic fatigue should always be investigated to rule out serious health issues.
