When to worry about fatigue with generalised anxiety disorder

Persistent worry can keep the body alert, interrupt sleep, tighten muscles, and make concentration harder. The result may be mental exhaustion, low motivation, or tiredness after ordinary tasks. Some medicines and alcohol or other substances can also alter sleep and energy.

Fatigue can have physical causes as well, such as anaemia, thyroid disease, infection, or sleep problems. A new or steadily worsening pattern should not be explained by anxiety without considering these possibilities.

Track sleep, worry, caffeine, medicines, mood, and energy for several days. Keep a regular wake time, reduce stimulating drinks later in the day, and use small, manageable activities rather than waiting to feel fully rested.

Arrange a review when fatigue affects work, relationships, personal care, or safe driving. Discuss whether your anxiety treatment is helping and whether another health check is sensible; do not stop prescribed medicine suddenly.

Seek urgent help for chest pain, severe breathing difficulty, fainting, sudden confusion, new one-sided weakness, or thoughts of self-harm. Contact a clinician promptly for rapidly worsening fatigue, several nights of almost no sleep, or inability to manage basic needs.

Ask whether your medicines, sleep, mood, or another condition could be contributing, whether tests are appropriate, and which practical changes would support both energy and anxiety control.
