A medical certificate is an official document issued by a healthcare professional, such as a doctor, confirming an individual's medical condition or fitness for specific activities. It typically includes details such as the patient's name, date of birth, the date of the examination, the nature of the illness or injury, any recommended treatments or medications, and the duration of the medical recommendation (such as time off work or restrictions on activities). These certificates are often required for various purposes, including sick leave from work or school, insurance claims, and legal documentation.
