Introduction To Disease

A disease or a disorder is the result of an abnormal change or disturbance in the structure or function of an organ or organ systems. This can be something as minor as a cold or something as serious as cancer. Diseases can either be acute or chronic. Acute diseases are temporary, and the affected person is expected to recover from them. Chronic diseases continue for a long period of time and can sometimes last for the person’s entire lifetime. Depending on their causes, diseases can be divided into certain categories including infectious diseases, degenerative diseases, nutritional diseases, metabolic or endocrine diseases, immune diseases, neoplastic diseases, and psychiatric diseases. Early diagnosis and treatment is essential for the best possible outcome in most cases of disease.
