Internal Medicine

What is Internal Medicine

Often referred to as “general medicine,” internal medicine encompasses a wide range of diseases and disorders affecting multiple organ systems in the body. Internists, or internal medicine physicians, are trained to handle complex and chronic conditions affecting various organ systems. They offer comprehensive care for the people, unlike specialists who focus on a specific organ or disease. The primary distinction between internal medicine specialists and family physicians is that the former cares for only adults, while family physicians treat both children and adults.

Components of Internal Medicine

Internal medicine takes a holistic approach to the treatment of adult diseases. Its components include:

• Preventive Medicine: Internal medicine focuses on preventive healthcare to decrease the risk of chronic diseases by promoting wellness through lifestyle changes and immunizations.
• Primary Care: The specialty addresses acute and chronic health conditions through timely intervention, stabilization, and management to reduce complications and improve a patient’s quality of life. 
• Subspecialty Care: There are various subspecialties within internal medicine. Subspecialists undergo additional training to develop expertise in treating specific organ systems or diseases.
• Geriatric Care: Internal medicine includes the healthcare of older people and helps manage age-related issues, chronic conditions, cognitive impairment, and functional decline through assessments, medication management, and fall prevention.
• Palliative Care: Palliative care is included in internal medicine. It includes symptom management, pain relief, and enhancing quality of life. The patients’ physical and emotional needs are handled throughout the illness.
• Research and Education: Internal medicine contributes to medical research by encouraging and facilitating clinical trials, publishing scientific papers, and advancing knowledge in various areas of internal medicine. This specialty also includes medical education and mentoring medical students.
