Osteoporosis (bone loss) is the primary disease associated with long-term
calcium deficiency; it may be associated with bone pain and spinal deformity.
Depleted levels can also cause muscle cramps, irregular heartbeat, and
Depleted levels of iron may lead to anemia and weakened immune function. In
the event of anemia, symptoms include dizziness, fatigue, shortness of breath,
pale skin color, and possibly irregular heartbeat.
Vitamin B9 (Folic
Low levels of folic acid have been linked to anemia, heart disease, and birth
Symptoms of vitamin B12 deficiency are rare because it takes years
to develop complications associated with long-term depletion of this nutrient.
Irritability, weakness, numbness, anemia, loss of appetite, headache,
personality changes, and confusion are some of the signs and symptoms associated
with vitamin B12 depletion. Low levels of this vitamin may also be
associated with an increased risk of colon cancer, heart disease, brain
disorders, and birth defects.
Vitamin D deficiency leads to abnormal bone formation (rickets) in children
and softening of the bones (osteomalacia) in adults. Vitamin D deficiency
interferes with calcium absorption, leading to deficiency of that nutrient with
all of the associated symptoms (such as increased risk of fractures,
osteoporosis (bone loss), and muscle weakness). Because this nutrient is
fat-soluble, prolonged periods of deficiency are required to produce these
Signs and symptoms of zinc deficiency include loss of appetite or sense of
taste, growth retardation, skin changes, and increased susceptibility to
The selected depletions information presented here identifies some of the
nutrients that may be depleted by certain medications. The signs and symptoms
associated with nutrient deficiency may also indicate conditions other than
nutrient deficiency. If you are experiencing any of the signs or symptoms
mentioned, it does not necessarily mean that you are nutrient deficient.
Nutrient depletion depends upon a number of factors, including your medical
history, diet, and lifestyle as well as the length of time you have been taking
the medication. Please consult your healthcare provider; he or she can best
assess and address your individual healthcare needs, and determine if you are at
risk for nutrient depletions from these medications as well as others not listed
