Protein issues Flashcards
Protein-Energy Malnutrition
PEM
= refers to a range of clinical syndromes characterized by an inadequate dietary intake of proteins and calories to meet the body’s needs Lack of protein, lack of calories, or both
Somatic protein compartment:
- Skeletal muscle
- Reserve protein source, take from here if needed
Visceral protein compartment:
- Predominantly in the liver
- Determine if this compartment is used by checking blood protein level
(specifically albumin)
Malnourished
–
Kwashiorkor
– 60 - 80% of normal weight*
- enough energy not enough protein
- hypoalbuminemia
- generalized edema
- hair changes (straightening, color loss)
- skin lesions
- fatty liver (steatosis)
- hepatomegaly
- apathy, listlessness, anorexia
- decreased immunity
- higher mortality rate than marasmus
Marasmus
–
Anorexia Nervosa
– self-induced starvation, resulting in marked weight loss
- Profound damage to endocrine system – especially pituitary and thyroid glands
Symptoms:
o Amenorrhea (no period) – huge decrease in gonadotropin-releasing (GnRH),
leutinizing (LH), and follicle-stimulating (FSH) hormones from pituitary
o Hypothyroidism – cold intolerance, constipation, bradycardia,
osteoporosis, cardiac arrhythmia, skin is dry and scaly
o Decreased immune system function
o Hypokalemia – resulting in arrhythmias, most common cause of death
o Low BP
o Low weight (though not from breasts)
Bulimia
– condition in which the patient binges on food and then induces vomiting
- Endocrine pathology though not as severe as with anorexia
Symptoms:
o Amenorrhea – present in 50% of patients
o Most common causes of death:
1) Aspiration pneumonia – inhalation of vomited particles along
with digestive enzymes digestion and inflammation of lungs
(also a common cause of death for alcohol abusers) 2) hypokalemia cardiac arrhythmias
3) Esophageal and heart rupture
irritation of esophagus Mallory Weiss syndrome = destruction of the distal
esophagus due to repetitive, long term vomiting
