What is fatigue and tiredness?
Feeling tired all the time (TATT) is a very common reason for seeing a GP. It can be caused by lifestyle factors (poor sleep, lack of exercise, diet), psychological conditions (stress, depression, anxiety), or medical conditions (anaemia, thyroid problems, diabetes).
When NHS resources suggest seeing a GP
- Tiredness has lasted for several weeks and rest does not help
- You have other symptoms like weight loss, muscle pain, or low mood
- You cannot think of anything that would explain the tiredness
- Your daily life is being affected
Self-care information from NHS
- Keep a regular sleep schedule
- Exercise regularly — even a daily walk helps
- Eat a balanced diet and stay hydrated
- Cut down on caffeine and alcohol
Common questions

The most common causes are poor sleep, stress, lack of physical activity, and diet. Medical causes include anaemia (low iron), underactive thyroid, diabetes, and depression. A GP can do blood tests to check.
What blood tests should I ask for?
Common tests for tiredness include full blood count (for anaemia), thyroid function, blood sugar (for diabetes), and vitamin D levels.
