Answer:
In health services, informed consent can be described as a permission given by the patient to the health care provider for treatment while being fully aware of the possible hazards and benefits of the particular treatment.
Informed consent is necessary so that no dispute arises between a health care provider and the patient or his family. Informed consent is an obligation for any health service. As every person has control over what is done to his/her body, hence an informed consent provides a legal permission for providing any kind of services to another person's body or mind.
