Refusing treatment: terminal illness
A terminal illness is an illness that cannot be cured and is likely to cause a person to die.
When an illness is diagnosed as terminal it means that a cure is no longer possible. At this point the person may be offered palliative care. Palliative care aims to achieve the best possible quality of life for the person who is ill by managing pain and other physical symptoms. It also supports any psychological, spiritual or social needs of the person and those close to them.
When an illness is diagnosed as terminal it is difficult to say exactly how long the person will live for. Many doctors diagnose an illness as terminal if the person is not expected to live for longer than six months, but some people will live for longer than this, and some will live for less.There are many conditions that can become terminal, including:
- Cancer (when some of the cells in the body divide abnormally causing growths called tumours or damage to the body’s immune system)
- Heart failure (when your heart cannot pump blood around your body as well as it needs to)
- Lung disease, including some types of chronic obstructive pulmonary disease (COPD) (when your airways become narrower making it harder to breathe)
- Excessive tiredness, drowsiness and weakness
- Difficulty breathing
- Changes to sight and hearing, including seeing things that others do not (hallucinations)
- Decreased appetite
- Nausea and vomiting
- Bladder and bowel problems
- Changes in mood and emotion
People with a terminal illness may also experience symptoms specific to their illness.
If you have a terminal illness that is in an advanced stage this does not necessarily mean that you will lose capacity. Many people with a terminal illness are able to make decisions about their medical treatment until their death. Remember that your Advance Decision will only come into effect if you lack capacity to make a decision about your medical treatment. So, if you have capacity you will continue to be able to make your own decisions.For more information on:
