Bipolar disorder affects your moods, which can swing from one extreme to another.
People with bipolar disorder have periods or episodes of:
Symptoms of bipolar disorder depend on which mood you're experiencing. Unlike simple mood swings, each extreme episode of bipolar disorder can last for several weeks (or even longer), and some people may not experience a 'normal' mood very often.
You may initially be diagnosed with clinical depression before having a future manic episode (sometimes years later), after which you may be diagnosed with bipolar disorder.
During an episode of depression, you may have overwhelming feelings of worthlessness, which can potentially lead to thoughts of suicide.
If you're feeling suicidal or having severe depressive symptoms, contact your doctor, care coordinator or local mental health emergency services as soon as possible.

During a manic phase of bipolar disorder, you may feel very happy and have lots of energy, ambitious plans and ideas. You may spend large amounts of money on things you can't afford and wouldn't normally want.
Not feeling like eating or sleeping, talking quickly and becoming annoyed easily are also common characteristics of this phase.
You may feel very creative and view the manic phase of bipolar as a positive experience. However, you may also experience symptoms of psychosis, where you see or hear things that aren't there or become convinced of things that aren't true.
The high and low phases of bipolar disorder are often so extreme that they interfere with everyday life.
However, there are several options for treating bipolar disorder that can make a difference. They aim to control the effects of an episode and help someone with bipolar disorder live life as normally as possible.
The following treatment options are available:
It's thought using a combination of different treatment methods is the best way to control bipolar disorder.
Help and advice for people with a long-term condition or their carers is also available from charities, support groups and associations.
This includes self-help and self-management advice, and learning to deal with the practical aspects of a long-term condition.
Bipolar disorder, like all other mental health problems, can get worse during pregnancy. However, specialist help is available if you need it.
The exact cause of bipolar disorder is unknown, although it's believed a number of things can trigger an episode. Extreme stress, overwhelming problems, and life-changing events are thought to contribute, as well as genetic and chemical factors.
Bipolar disorder is fairly common and one in every 100 adults will be diagnosed with the condition at some point in their life.
Bipolar disorder can occur at any age, although it often develops between the ages of 15 and 19.
The pattern of mood swings in bipolar disorder varies widely between people. For example, some people only have a couple of bipolar episodes in their lifetime and are stable in between, while others have many episodes.
Bipolar disorder is characterised by extreme mood swings. These can range from extreme highs (mania) to extreme lows (depression).
Episodes of mania and depression often last for several weeks or months.
During a period of depression, your symptoms may include:
The manic phase of bipolar disorder may include:
If you have bipolar disorder, you may have episodes of depression more regularly than episodes of mania, or vice versa.
Between episodes of depression and mania, you may sometimes have periods where you have a "normal" mood.
The patterns aren't always the same and some people may experience:
If your mood swings last a long time but aren't severe enough to be classed as bipolar disorder, you may be diagnosed with cyclothymia (a mild form of bipolar disorder).
Bipolar disorder is a condition of extremes. A person with the condition may be unaware they're in the manic phase.
After the episode is over, they may be shocked at their behaviour. However, at the time, they may believe other people are being negative or unhelpful.
Some people with bipolar disorder have more frequent and severe episodes than others. The extreme nature of the condition means staying in a job may be difficult and relationships may become strained. There's also an increased risk of suicide .
During episodes of mania and depression, someone with bipolar disorder may experience strange sensations, such as seeing, hearing or smelling things that aren't there (hallucinations).
They may also believe things that seem irrational to other people (delusions). These types of symptoms are known as psychosis or a psychotic episode.
The exact cause of bipolar disorder is unknown. Experts believe there are a number of factors that work together to make a person more likely to develop the condition.
These are thought to be a complex mix of physical, environmental and social factors.
Bipolar disorder is widely believed to be the result of chemical imbalances in the brain.
The chemicals responsible for controlling the brain's functions are called neurotransmitters and include noradrenaline, serotonin and dopamine.
There's some evidence that if there's an imbalance in the levels of one or more neurotransmitters, a person may develop some symptoms of bipolar disorder .
For example, there's evidence that episodes of mania may occur when levels of noradrenaline are too high, and episodes of depression may be the result of noradrenaline levels becoming too low.
It's also thought bipolar disorder is linked to genetics, as the condition seems to run in families. The family members of a person with the condition have an increased risk of developing it themselves.
However, no single gene is responsible for bipolar disorder. Instead, a number of genetic and environmental factors are thought to act as triggers.
A stressful circumstance or situation often triggers the symptoms of bipolar disorder. Examples of stressful triggers include:
These types of life-altering events can cause episodes of depression at any time in a person's life.
Bipolar disorder may also be triggered by:
If your doctor thinks you may have bipolar disorder, they'll usually refer you to a psychiatrist (a medically qualified mental health specialist).
If your illness puts you at risk of harming yourself, your doctor will arrange an appointment immediately.
You'll be assessed by the psychiatrist at your appointment. They'll ask you a few questions to determine if you have bipolar disorder. If you do, they'll decide what treatments are most suitable.
During the assessment, you'll be asked about your symptoms and when you first experienced them. The psychiatrist will also ask about how you feel leading up to and during an episode of mania or depression, and if you have thoughts about harming yourself .
The psychiatrist will also want to know about your medical background and family history, especially whether any of your relatives have had bipolar disorder.
If someone else in your family has the condition, the psychiatrist may want to talk to them. However, they'll ask for your agreement before doing so.
If you have bipolar disorder, you'll need to visit your doctor regularly for a physical health check.
If you're diagnosed with the condition, it's important to talk to your psychiatrist so you're fully involved in the decisions about your treatment and care.
However, a person is sometimes not able to make an informed decision about their care or communicate their needs, especially if their symptoms become severe. If this happens, it may be possible to draw up an advanced decision.
An advanced decision is a set of written instructions that state what treatments and help you want (or don't want) in advance, in case you can't communicate your decisions at a later stage. Your doctor or psychiatrist can give you further help and advice.
Treatment for bipolar disorder aims to reduce the severity and number of episodes of depression and mania to allow as normal a life as possible.
If a person isn't treated, episodes of bipolar-related mania can last for between three and six months. Episodes of depression tend to last longer, for between six and 12 months.
However, with effective treatment, episodes usually improve within about three months.
Most people with bipolar disorder can be treated using a combination of different treatments. These can include one or more of the following:

Most people with bipolar disorder can receive most of their treatment without having to stay in hospital.
However, hospital treatment may be needed if your symptoms are severe, or if you're being treated under the Mental Health Act, as there's a danger you may self-harm or hurt others.
In some circumstances, you could have treatment in a day hospital and return home at night.
Several medications are available to help stabilise mood swings. These are commonly referred to as mood stabilisers and include:
If you're already taking medication for bipolar disorder and you develop depression, your doctor will check you're taking the correct dose. If you aren't, they'll change it.
Episodes of depression are treated slightly differently in bipolar disorder, as the use of antidepressants alone may lead to a hypomanic relapse.
Most guidelines suggest depression in bipolar disorder can be treated with just a mood stabiliser. However, antidepressants are commonly used alongside a mood stabiliser or antipsychotic.

If your doctor or psychiatrist recommends you stop taking medication for bipolar disorder, the dose should be gradually reduced over at least four weeks, and up to three months if you are taking an antipsychotic or lithium.
If you have to stop taking lithium for any reason, see your doctor about taking an antipsychotic or valproate instead.
In the UK, lithium carbonate (often referred to as just lithium) is the medication most commonly used to treat bipolar disorder.
Lithium is a long-term method of treatment for episodes of mania, hypomania and depression. It's usually prescribed for at least six months.
If you're prescribed lithium, stick to the prescribed dose and don't stop taking it suddenly (unless told to by your doctor).
For lithium to be effective, the dosage must be correct. If it's incorrect, you may get side effects such as diarrhoea and vomiting. However, tell your doctor immediately if you have side effects while taking lithium.
You'll need regular blood tests at least every three months while taking lithium. This is to make sure your lithium levels aren't too high or too low.
Your kidney and thyroid function will also need to be checked every two to three months if the dose of lithium is being adjusted, and every 12 months in all other cases.
While you're taking lithium, avoid using non-steroidal anti-inflammatory drugs (NSAIDs) , such as ibuprofen , unless they're prescribed by your doctor.
In the UK, lithium and the antipsychotic medicine aripiprazole are currently the only medications licensed for use in adolescents with bipolar disorder who are aged 13 or over.
However, the Royal College of Paediatrics and Child Health states that unlicensed medicines may be prescribed for children if there are no suitable alternatives and their use can be justified by expert agreement.
Anticonvulsant medicines include:
These medicines are sometimes used to treat episodes of mania. They're also long-term mood stabilisers.
Anticonvulsant medicines are often used to treat epilepsy , but they're also effective in treating bipolar disorder.
A single anticonvulsant medicine may be used, or they may be used in combination with lithium when the condition doesn't respond to lithium on its own.
Valproate isn't usually prescribed for women of childbearing age because there's a risk of physical defects to babies such as spina bifida, heart abnormalities and cleft lip. There may also be an increased risk of developmental problems such as lower intellectual abilities, poor speaking and understanding, memory problems, autistic spectrum disorders and delayed walking and talking.
Learn more about the risks of valproate medicines during pregnancy.
In women, your doctor may decide to use valporate if there's no alternative or if you've been assessed and it's unlikely you'll respond to other treatments, although they'll need to check you're using a reliable contraception and advise you on the risks of taking the medicine during pregnancy.
If you're prescribed valproate, you'll need to visit your doctor to have a blood count when you begin the medication, and then again six months later.
Carbamazepine is usually only prescribed on the advice of an expert in bipolar disorder. To begin with, the dose will be low and then gradually increased.
Your progress will be carefully monitored if you're taking other medication, including the contraceptive pill.
Blood tests to check your liver and kidney function will be carried out when you start taking carbamazepine, and again after six months.
You'll also need to have a blood count at the start and after six months, and you may also have your weight and height monitored.
If you're prescribed lamotrigine, you'll usually be started on a low dose, which will be increased gradually.
See your doctor immediately if you're taking lamotrigine and develop a rash. You'll need to have an annual health check, but other tests aren't usually needed.
Women who are taking the contraceptive pill should talk to their doctor about taking a different method of contraception.
Antipsychotic medicines are sometimes prescribed to treat episodes of mania or hypomania. Antipsychotic medicines include:
They may also be used as a long-term mood stabiliser. Quetiapine may also be used for long-term bipolar depression.
Antipsychotic medicines can be particularly useful if symptoms are severe or behaviour is disturbed. As antipsychotics can cause side effects – such as blurred vision, dry mouth, constipation and weight gain – the initial dose will usually be low.
If you're prescribed an antipsychotic medicine, you'll need to have regular health checks at least every three months, but possibly more often, particularly if you have diabetes. If your symptoms don't improve, you may be offered lithium and valproate as well.
Aripiprazole is also recommended by the National Institute for Health and Care Excellence (NICE) as an option for treating moderate to severe manic episodes in adolescents with bipolar disorder.
You may be prescribed a combination of lithium and valproate if you experience rapid cycling (where you quickly change from highs to lows without a "normal" period in between).
If this doesn't help, you may be offered lithium on its own or a combination of lithium, valproate and lamotrigine.
However, you won't usually be prescribed an antidepressant unless an expert in bipolar disorder has recommended it.
If you have bipolar disorder, you can learn to recognise the warning signs of an approaching episode of mania or depression.
A community mental health worker, such as a psychiatric nurse, may be able to help you identify your early signs of relapse from your history.
This won't prevent the episode occurring, but it will allow you to get help in time.
This may mean making some changes to your treatment, perhaps by adding an antidepressant or antipsychotic medicine to the mood-stabilising medication you're already taking. Your doctor or specialist can advise you on this.
Some people find psychological treatment helpful when used alongside medication in between episodes of mania or depression. This may include:
Psychological treatment usually consists of around 16 sessions. Each session lasts an hour and takes place over a period of six to nine months.
The management of bipolar disorder in women who are pregnant , or those who are trying to conceive, is complex and challenging.
One of the main problems is the risks of taking medication during pregnancy aren't always that well understood.
The National Institute for Health and Care Excellence (NICE) recommends that the risks of treating or not treating women with bipolar disorder during pregnancy should be fully discussed.
NICE also recommends that specialist mental health services work closely with maternity services.
A written plan for managing the treatment of a pregnant woman with bipolar disorder should be developed as soon as possible.
The plan should be drawn up with the patient, her partner, her obstetrician (pregnancy specialist), midwife, doctor and health visitor.
The following medication isn't routinely prescribed for pregnant women with bipolar disorder:
If you become pregnant while taking medication prescribed to treat bipolar disorder, it's important that you don't stop taking it until you've discussed it with your doctor.
If medication is prescribed for bipolar disorder after the baby is born, it may also affect a mother's decision to breastfeed her child. Your pharmacist, midwife or mental health team can give you advice based on your circumstances.
