Pediatrics

Pediatrics is a special branch of medicine. It focuses on the care of infants, children, adolescents, and young adults.

A doctor who specializes in this field is called a pediatrician. The name comes from two Greek words. One word means "child" and the other means "healer."

Different places have different age limits for this care. In India, it covers children up to age 12. In many Commonwealth countries, it goes up to age 18. The American Academy of Pediatrics suggests care through age 21. Some specialists even care for young adults up to age 26.

Children are not just tiny versions of adults. Their bodies work in many different ways. For example, a baby's stomach has less acid than an adult's. This makes the stomach environment more basic. Because of this, some medicines might stay in the system longer. A child's body also has different amounts of water. This affects how medicine spreads through their blood.

Doctors must also watch how kidneys and livers grow. A baby's kidneys might clear medicine very quickly. Other babies might have slower kidneys that need smaller doses. Pediatricians must use very careful math to find the right amount.

People have studied child health for thousands of years. The earliest notes appear in the Hippocratic Corpus from the fifth century B.C. Ancient Greek doctors like Celsus and Galen wrote about childhood illnesses. They knew that boys should not be treated like men.

In Ancient India, doctors were called kumara bhrtya. Old texts like the Sushruta Samhita also contain medical info. During the Islamic Golden Age, writers like al-Razi helped bridge medical knowledge. Al-Razi is sometimes called the father of pediatrics. He wrote a book called "Diseases in Children."

Modern pediatrics began to grow in the 1700s. Nils Rosén von Rosenstein is often called the founder of modern pediatrics. He wrote a famous textbook in 1764.

The first children's hospital in the English-speaking world was Great Ormond Street Hospital. It opened in London in 1852. In the United States, the Children's Hospital of Philadelphia opened in 1855. Other important hospitals opened in Boston in 1869. These places helped make child care a separate field of medicine.

Working with children also means working with families. In most places, children cannot make their own legal health decisions. This involves complex rules about guardianship and consent. Pediatricians must talk to parents to decide on treatments.

Adolescents are a special group in this process. They often have more rights to make their own health choices. Doctors try to listen to the child's wishes too. This is called assent, which means the child agrees to the care. It helps the doctor respect the young person while following the law.
