When to see a doctor
See a doctor urgently if:
- If your stress is unbearable or you have thoughts of harming yourself, call your local emergency number or a crisis helpline right away.
- If you have chest pain or trouble breathing, call your local emergency number immediately.
Book a routine appointment if:
- If stress is stopping you from sleeping, working, or enjoying life for more than a few weeks.
- If you feel anxious, tearful, or unable to cope most days.
Diagnosis
A healthcare professional will ask about your feelings, your recent life events, and how the stress is affecting you. There is no single test.
Tests that may be done
- There are no lab tests for stress itself.
- Your doctor may check your blood pressure and heart rate.
- They may order routine blood tests to rule out other health problems.
What to expect at your appointment
You will have a private conversation in a calm setting. The professional will listen without judgment and may ask about your sleep, mood, and support network.
Treatment
Treatment depends on how severe and long-lasting your stress is. For many people, support and self-care are enough. If stress persists, talking therapies can help you cope. Any medicines for anxiety or depression are prescribed by a doctor after a full discussion of your situation.
Self-care at home
- Take slow, deep breaths when you feel overwhelmed.
- Move your body in a way you enjoy, like walking.
- Reach out to a friend or family member you trust.
- Cut down on caffeine, alcohol, and sugary drinks.
- Try to keep a regular sleep schedule.
- Give yourself small breaks during the day.
Medical treatments
Talking therapies, such as cognitive behavioural therapy (CBT), can help you change unhelpful thought patterns. In some cases, a doctor may discuss medication to help with anxiety or low mood. Medication is never prescribed without a conversation about benefits and risks, and it is not a cure by itself.
When is surgery considered?
Surgery is not a treatment for sudden stress.
