Geriatrics is derived from the Greek words geron, which means "old man," and iatros, which means "healer." Geriatrics, on the other hand, is also known as medical gerontology. Geriatrics, often known as geriatric medicine, is a medical speciality that focuses on the care of the aged. Its goal is to improve older people' health by preventing and treating diseases and disabilities. A geriatrician, or geriatric physician, is a physician who specialises in the care of elderly people. There is no specific age at which patients can be seen by a geriatrician, or geriatric physician. The gastrointestinal (GI) tract poses unique complications for both the patient and the practitioner as they age. A variety of factors, including environmental exposures, acquired genetic and cellular alterations, drugs, and medical procedures, all contribute to greater disturbances of normal GI function as patients age.
