Poisoning is when a person is exposed to a substance that can damage their health or endanger their life.
In 2013-14, almost 150,000 people were admitted to hospital with poisoning in England.
Most cases of poisoning happen at home and children under five have the highest risk of accidental poisoning.
In around one in four reported cases, the person intentionally poisoned themselves as a deliberate act of Self-harm .
The symptoms of poisoning will depend on the type of poison and the amount taken in, but general things to look out for include:
