Many people visit the hospital for the diagnosis and treatment of conditions like diabetes, high blood pressure, thyroid problems, or infections, yet many are unaware of internal medicine, one of the most important branches of healthcare.

Let's explore in detail “what is internal medicine?” and “when to see an internal medicine doctor.”

What Is Internal Medicine

Internal medicine (also known as general medicine, especially in many Commonwealth countries) is an integral part of the healthcare setting. 

It focuses on prevention, diagnosis, and treatment of a wide range of conditions affecting the internal organs of the body – the heart, the lungs, the liver and gastrointestinal tract, the kidneys and urinary tract, the brain, the spinal column, nerves, muscles, and joints. Doctors who practise internal medicine are known as internists.

Common Conditions Treated by Doctors of Internal Medicine, “Internists”

An internist diagnoses, treats, and prevents diseases that affect the internal organs of adults.

The conditions includes:

Category	Conditions
Cardiovascular issues	High blood pressure, high cholesterol, heart failure
Endocrine and metabolic disorders	Diabetes, thyroid diseases, other hormonal imbalances
Respiratory diseases	Asthma, chronic obstructive pulmonary disease (COPD), lung infections like pneumonia and bronchitis
Digestive and liver problems	Acid reflux (GERD), irritable bowel syndrome (IBS), peptic ulcers, fatty liver disease, cirrhosis
Kidney and urinary problems	Chronic kidney disease, electrolyte imbalances, urinary tract infections (UTIs)
Musculoskeletal issues	Arthritis, chronic joint pain, some soft-tissue problems
Neurological complaints	Migraines, neuropathy (nerve pain), memory-related concerns
Infectious diseases	Flu, respiratory infections, skin infections, gastrointestinal infections, and more
