  1. Vitamin A
    • slow recovery of vision after flashes of bright light at night is the first ocular symptom; can progress to xerophthalmaia and blindness
    • bone growth ceases; bone shape changes;enamel-forming cells in teeth malfunction; teeth crack and tend to decay
    • skin becomes dry, scaly, rough, and cracked; keratinization or hyperkeratosis develops; mucous membrane cells flatten and harden: eyes become dry (xerosis); irreversible drying and hardening of the cornea can result in blindness.
    • decreased saliva secretion-difficulty chewing, swallowing-anorexia
    • decreased mucous secretion of the stomach and intestines-impaired digestion and absorption-diarrhea, increased excretion of nutrients
    • impaired immune system functioning-increased susceptibility to respiratory, urinary tract, and vaginal infections increases
  2. Vitamin D
    • -Rickets (in infant and children):
    • retarded bone growth,
    • bone malformations (bow legged), enlargement of ends of long bones (knock-knees),
    • deformities of the ribs ( bowed, with beads and knobs)
    • delayed closing of the fontanel- rapid enlargement of the head
    • decreased serum calcium and/or phosphorus
    • malformed teeth; decayed teeth
    • protrusion of the abdomen related to relaxation of the abdominal muscles
    • increased secretion of the parathyroid hormone
    • -osteomalacia (in adults)
    • softening of the bones-deformities, pain and easy fracture
    • decreased serum calcium and/or phosphurus, increased alkalina phosphatase
    • involuntary muscle twitching and spasms

  11. Pantothenic acid
    rare; general failure of all body systems
  12. Biotin
    rare; anorexia, fatigue, deppression, dry skin, heart abnormalities
  13. Vitamin C
    • -bleeding gums, pinpoint hemorrhages under the skin
    • -scurvy, characterized by
    • hemorrhaging
    • muscle degeneration
    • skin changes
    • delayed wound healing:reopening of old wounds
