Internal Medicine Q & A

What is internal medicine?

Internal medicine refers to some medical specialties that handle the prevention, diagnosis, and treatment of adult diseases. Dr. Choi specializes in understanding undefined symptoms, developing preventive plans, and offering comprehensive health management.

More often than not, patients tend to seek treatment from primary care physicians rather than go immediately for specialized treatment. Internal medicine helps you target the source of your condition and find useful treatment options to get rid of it.

What are the subspecialties of internal medicine?

The subspecialties of internal medicine include:


Pulmonologists specialize in treating lung-related conditions like asthma and chronic bronchitis. Internists focusing on this field also provide treatment for sleep apnea.


Endocrinology is the treatment of hormone and gland issues. Diabetes is one of the leading conditions endocrinologists treat. Since diabetes deals with complications related to insulin, endocrinologists are the experts in the field.


Cardiology focuses on preventing conditions related to heart and blood vessels, like heart attacks or congestive heart failure, where the heart doesn’t pump blood with the strength it should.


Internists specializing in gastroenterology treat conditions that affect the digestive system, such as:

  • Chronic heartburn
  • Indigestion
  • Stomach pain
  • Diarrhea and constipation
  • Irritable Bowel Syndrome (IBS)
  • Hepatology
  • Hepatologists focus exclusively on the liver.
  • Hematology/Oncology

These two subspecialties refer to issues relating to blood disorders and cancer, like anemia and breast, lung, and colon cancer.


Nephrology deals with conditions related to the kidneys.


Rheumatologists handle issues that affect the immune system, typically autoimmune disorders such as arthritis and lupus.


Allergists and immunologists test for substances or foods that may cause an allergic reaction.

Infectious Diseases

Doctors specialize in treating contagious diseases based in any of the following conditions:

  • Bone infections
  • Severe skin infections
  • Geriatrics

Geriatricians specialize in care for the elderly, and see patients as young as age 65, though typically their patients are 80 years old and older.

What is the difference between an internist and an intern?

An internist refers to a physician specializing in internal medicine, as opposed to an intern, who is a physician-in-training in their first year of post-graduate training.
