Anorexia Nervosa01:28

Anorexia Nervosa

Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Bulimia Nervosa01:30

Bulimia Nervosa

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...
Binge Eating Disorders01:23

Binge Eating Disorders

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...
Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion01:18

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Area of Science:

  • Geriatric Medicine
  • Psychiatry
  • Public Health

Background:

  • Eating disorders in the elderly are frequently misdiagnosed or ignored.
  • These conditions in older adults are associated with substantial morbidity and mortality.
  • Existing literature on geriatric eating disorders is reviewed to inform clinical practice.

Purpose of the Study:

  • To review the literature on eating disorders in individuals over 50.
  • To provide clinical guidelines for recognizing and managing these disorders in the elderly.
  • To highlight the importance of considering eating disorders in the differential diagnosis of elderly patients with unexplained weight loss.

Main Methods:

  • A comprehensive literature search was conducted using major databases (Medline, PubMed, Web of Knowledge, PsychINFO).
  • The search identified 48 published cases of eating disorders in individuals aged 50 years and older.
  • Data from these cases were analyzed to identify trends and characteristics.

Main Results:

  • The study included 48 cases with a mean age of 68.6 years; 88% were female.
  • Anorexia nervosa (81%) was the most common diagnosis, followed by bulimia nervosa (10%).
  • Late-onset eating disorders (69%) were more prevalent than early-onset, with high comorbidity (60%) including major depression; mortality was 21%.

Conclusions:

  • Eating disorders are a significant concern in the elderly population.
  • These disorders must be considered in the differential diagnosis of unexplained weight loss in older adults.
  • Combined behavioral and pharmacological interventions show promise but success rates remain moderate.
