When to see an internal medicine physician
Common reasons people book a consultation.

- A medication review across several specialists
- Fever or weight loss investigated without an answer
What an internal medicine physician does
An internal medicine physician, often listed as a consultant physician or MD Medicine, is a specialist in adult illness that is treated without surgery. In India this usually means an MBBS followed by a three-year postgraduate degree, MD in general medicine or DNB in general medicine. Internal medicine is also the base from which many super-specialists start: most cardiologists, nephrologists, gastroenterologists and neurologists trained in general medicine first.
The distinctive skill is handling several problems at once. A patient with diabetes, kidney disease and heart failure, taking a dozen medicines prescribed by different doctors, needs someone who sees how the conditions and treatments affect each other. Internal medicine physicians also take on puzzles: a fever that will not settle, weight loss without a clear cause, or symptoms that do not point to any one organ.
In most Indian hospitals the general medicine department runs the medical wards. If you are admitted with an infection, uncontrolled diabetes or an illness that is not yet diagnosed, you are likely to be under a physician who coordinates tests and calls in other specialists as needed. Many also run outpatient clinics, where the work overlaps with general practice but tends towards more complex cases.

Internal medicine physician or another specialist?
The nearest neighbouring specialities, and when each is the right door.
Before your first visit
- Bring all your prescriptions and every medicine you take, ideally in their packets, including supplements and traditional remedies.
- Bring earlier reports and discharge summaries in date order. For a long illness, a one-page timeline of what happened when is very useful.
- List your diagnoses and the specialists you see, so the physician can see the whole picture.
- Expect a detailed history and a full examination. Blood tests are usually ordered on the day and the plan is set once results are in.
- Ask which doctor is coordinating your care, and whom to contact if things change.
Qualifications and registration to check
Registered with the National Medical Commission or a state medical council. The number can be searched on the NMC's Indian Medical Register. Every profile on The Doctor Index shows the registration number and says whether it has been checked against the register.

What is the difference between an MD Medicine and an MBBS doctor?
An MBBS doctor has completed basic medical training and can practise as a general physician. An MD in general medicine has done a further three years of postgraduate training in adult medicine, much of it in hospital wards.
When should I see an internal medicine physician rather than a super-specialist?
When your problems cross several organs, or it is not yet clear what is wrong. A physician can sort out the overall picture and refer you to the right super-specialist when one organ clearly needs it.
Do internal medicine physicians treat children?
Usually not. Internal medicine is adult medicine; children are generally seen by a paediatrician.
Can a physician reduce the number of medicines I take?
A physician can review all your medicines together and may be able to stop ones that are duplicated or no longer needed. Do not stop any medicine on your own; changes should be made with the doctor who prescribed it.
Who looks after me if I am admitted to hospital with a fever?
In many Indian hospitals, adults admitted with a fever or a medical illness are under the general medicine team, who call in other specialists as needed.
Also searched as: md medicine, medicine specialist, general medicine, consultant physician.
