Physiological systems affected by easting disorders
❤️Cardiovascular
Low ❤️ rate
Decreased cardiac output
Increased risk of cardiac arrest
Structural changes to the ❤️ leading to
inefficient pump
Decreased cardiac output
Poor peripheral perfusion:
acrocyanosis
Hypotension
Hypothermia
💦Fluids and electrolytes
Dehydration & electrolyte abnormalities due to:
Poor oral intake of fluids to minimize water weight
Vomiting
Laxative use
Diuretics use (pee more!)
"Refeeding syndrome": changes in metabolism when there's a sudden change from starvation to re-feeding
symptoms & consequences
fatigue
muscle pain
❤️ failure
death
electrolytes involved
potassium
magnesium
phosphorus
avoid via progressive reintroduction of normal feeding
dehydration
Low blood pressure
shock & organ injury (esp. kidneys)
altered cognition
❤️ failure
death
electrolyte abnormalities
cardiac arythmia
cardiac arrest
death
lethargy
seizures
coma
permanent neurological injury
water loading
: excessive water intake (8-12 gallons per day)
🧠Neuropsychiatric
structural changes (altered neural circuits)
impaired cognitive abilities
anxiety, depression, psychosis
💩Gastrointestinal
constipation due to malnutrition and abuse of laxatives
delayed gastric emptying
acid reflux
blood in vomit, damaged esophagus and esophageal rupture
pancreatitis
decreased appetite due to bloating
♂♀ Reproductive
incomplete pubertal development
low hormone levels
decreased sex drive in men
absent periods and infertility in women
💪 Muscoskeletal
incomplete linear growth & height stunting
decreased bone density
osteoporosis
muscle wasting, weakness and pain
💉Hematologic
Anemia
Immune suppression
👄Head & neck
🤮sequels of vomiting
parotid hypertrophy (swollen glands)
dental erosion
oral abrasions
😧Dermatologic
Lanugo (lots of hair)
Russell sign
poor wound healing
dry skin
hair loss
🌬️Respiratory
Aspiration pneumonia (vomit in lungs)
respiratory sequels from ❤️ failure
