Anorexia (deriving from the Greek "α(ν)-" (a(n)-, a prefix that denotes absence) + "όρεξη (orexe)</i> = appetite) is the decreased sensation of appetite. While the term in non-scientific publications is often used interchangeably with anorexia nervosa, many possible causes exist for a decreased appetite, some of which may be harmless, while others indicate a serious clinical condition, or pose a significant risk.

CausesEdit

  • Satiation following the consumption of food. This is normal and is called postprandial anorexia.

Clinically importantEdit

  • Acute Radiation Syndrome.
  • AIDS.
  • Anorexia nervosa.
  • acute appendicitis where it accompanies the presenting symptom of abdominal pain, often with vomiting.
  • Cancer.
  • Chronic renal failure.
  • Congestive heart failure, perhaps due to congestion of the liver with venous blood.
  • Crohn's Disease.
  • Dementia.
  • Severe Depression.
  • Sickness behavior[1][2]
  • Superior Mesenteric Artery Syndrome.
  • Ulcerative Colitis.

DrugsEdit

  • Amphetamine (Adderall), dextroamphetamine (Dexedrine & Dextrostat).
  • Antidepressants can have anorexia as a side effect.
  • Dextromethylphenidate (Focalin).
  • Abrupt cessation of appetite-increasing drugs, such as cannabis.
  • Methamphetamine (Desoxyn) (treatment of ADD & ADHD and narcolepsy).
  • Methylphenidate (Ritalin & Concerta).
  • Chemicals that are members of the phenethylamine group. (Individuals with anorexia nervosa may seek them to suppress appetite).
  • Stimulants.

OtherEdit

  • Altitude when it can also accompany sickness.
  • Preoperative anorexia drugs may be prescribed as a prophylactic to ensure no food will back up into the esophagus which might risk pulmonary aspiration.
  • Significant emotional pain caused by an event (rather than a mental illness) can cause an individual to temporarily lose all interest in eating.
