What Are the Various Types of Doctors

As of June 2022, the total number of allopathic doctors registered with the State Medical Councils and the National Medical Commission in India was 13,08,009. Given the nation’s population, we have a doctor-patient ratio of 1:834. In other words, every allopathic doctor treats 834 patients.

This means India’s doctor-patient ratio doesn’t simply meet but surpasses the World Health Organisation’s (WHO) norm of 1:1000. Within these 13 lakh doctors, not all specialise in the same field. There are various types of doctors in India, which can be broadly categorised into primary care and specialist doctors.

Primary care doctors are medical professionals trained to diagnose, prevent, and treat minor injuries and illnesses. These include common colds, cases of flu, allergic reactions, etc.

On the other hand, specialist doctors are medical professionals that have undergone focused training in a specific area of medicine. There are various types of doctors within this category, and the types of specialists that you should know about are listed below. 

  •   Cardiologist

These doctors specialise in treating the cardiovascular system, including the heart and blood vessels. They treat patients who have suffered a heart attack, are at risk of one, or suffer from high blood pressure, high cholesterol, heart rhythm problems, etc.

  •   Oncologist

Their expertise lies in identifying, treating and preventing the spread of cancer. Within this field, there are three types of oncologists. Each of these differs based on the kind of treatment subscribed. The type of oncologist depends on the type of cancer and its stage, among other factors.

Radiation Oncologists: These doctors use radiation therapy to treat cancer. The treatment includes using high-energy X-rays or other particles to eliminate cancer cells.

Medical Oncologists: These doctors treat cancer with medication like immunotherapy, targeted therapy, and chemotherapy.

Surgical Oncologists: These doctors perform surgical procedures such as tumour removal and conduct biopsies as part of their cancer treatment


  • Obstetrician/ Gynaecologist (OB/GYN)

These doctors have a special focus on women’s health. While Obstetricians specialise in caring for pregnant women and are trained in childbirth, Gynaecologists focus on the patient’s reproductive health. Since their expertise is interconnected, these two specialists often work together.

  •   Neurologist

These specialists treat conditions affecting the brain, nerves and spine. Common disorders include multiple sclerosis, Parkinson’s disease, epilepsy, etc. Their forms of treatment include medication, physical therapy, and similar procedures.
