Bipolar disorder

Self-care

The main symptoms of bipolar disorder are extreme high moods (such as feeling very happy or excited) and low moods (such as feeling sad or hopeless).

To diagnose bipolar disorder, a GP will refer you to a mental health specialist who will ask you about your moods, behaviour and family history.

The main treatments to help manage bipolar disorder are medicines to help stabilise your moods and talking therapy.

If you have bipolar disorder, it can help to have a regular routine, get enough sleep, eat healthily, exercise and try to avoid and manage stress.

Symptoms of bipolar disorder

The main symptom of bipolar disorder is extreme changes to your mood.

You sometimes have either:

  • high moods (mania or hypomania) – for example, feeling very happy, excited or energetic
  • low moods (depression) – for example, feeling sad, tired or hopeless

These moods usually last a few days or weeks at a time.

If you have bipolar disorder, you will usually have times where your mood is stable and you do not have any symptoms. This can last for weeks, months or years.

See a GP if:

  • you have extreme changes in your moods that last a long time or impact your everyday life
  • you've been diagnosed with bipolar disorder and treatments are not helping (or speak to your mental health specialist if you have one)

If you're worried about someone else, encourage them to speak to their GP.

How bipolar disorder is diagnosed

If a GP thinks you may have bipolar disorder or another mental health condition, they will refer you to a mental health specialist (psychiatrist).

The mental health specialist will ask you about things like your moods, behaviour, health and family history.

Bipolar disorder can take time to diagnose because it affects everyone differently and the symptoms are similar to other mental health conditions.

Treatment for bipolar disorder

Bipolar disorder cannot be cured, but there are treatments that can help manage it.

A mental health specialist will work with you to create a treatment plan.

Treatments you may have include:

Some medicines you need to take all the time, others you only take when your symptoms get worse.

The medicines can cause side effects. These will vary depending on which medicine you take and how your body responds to it.

You'll usually have appointments at a GP surgery, clinic or hospital.

If doctors are worried you're at risk of self-harm, suicide or harming someone else, you may need to stay in hospital or have support from a crisis team at home.

Important

Do not stop taking your bipolar disorder medicine unless you are told to by a doctor, even if you feel better.

Some medicines for bipolar disorder are not safe to take if you are pregnant. Talk to your doctor if you are pregnant or planning a pregnancy.

Things you can do to help with bipolar disorder
