Fatigue
It's normal to feel tired sometimes. But if you're tired all the time and do not know why, it could be a sign of a problem.
Causes of tiredness and fatigue
Common causes of tiredness and fatigue include:
- not getting enough sleep or finding it hard to get to sleep (insomnia)
- an unhealthy lifestyle (such as having an unhealthy diet and not getting much exercise)
- stress, depression and dealing with life challenges, such as bereavement or looking after a new baby
- hormonal changes (such as during puberty, pregnancy or the menopause)
- some illnesses, like glandular fever and COVID-19
- some medical treatments and medicines, like chemotherapy, which can cause drowsiness for a while
But if you cannot explain why you're tired and it's been going on for a while and not getting any better, it may be a sign of a medical condition.
Your symptoms might give you an idea of what's causing your tiredness or fatigue. But do not self-diagnose – see a GP if you're worried.
