73. Vitamins A deficiency
disorders
Vitamin A helps maintain healthy vision.
Without vitamin A, a person could
experience vision problems and possibly
vision loss. Vitamin A deficiency is rare in
the United States, but it can affect a
person who:
follows a plant-based diet
has cystic fibrosis
A long-term deficiency can lead to a loss
of night vision and possibly a total loss of
vision.

75. Vitamins D deficiency
disorders
A vitamin D deficiency can affect:
older adults and children who do not spend much time out
of doors
people with darker skin
some people with chronic health conditions
those who live far from the Equator, where winter days
are short
those with obesity
The main effects of vitamin D deficiency include:
osteoporosis, or loss of bone mass
osteomalacia, when bones become soft
rickets, when a child’s bones do not develop as they
should
increased risk of infection and autoimmunity

77. Vitamins E deficiency
disorders
Vitamin E deficiency is rare, but it can affect
people with Crohn’s disease or cystic
fibrosis. These conditions affect the liver’s
ability to absorb vitamin E.
A deficiency can result in:
nerve and muscle damage that affects
movement and coordination
vision problems
a weakened immune system
As vitamin E is an antioxidant, a long-term
deficiency could increase the overall risk of
various diseases.

79. Vitamins K deficiency
disorders
The body is not able to store as much
vitamin K as it does vitamin A or D. This
means a person needs a regular intake of
vitamin K, and there is a higher chance of a
deficiency.
A vitamin K deficiency may result in:
excess bleeding
lower bone density, in the long term.
Vitamin K deficiency in adults is rare but
does occur in infants. The main symptom of
a vitamin K deficiency is excessive bleeding
caused by an inability to form blood clots.
