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 depression.

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.

Magnesium deficiency affects calcium and vitamin D levels in the body and may be associated with muscle cramps, heart irregularities, high blood pressure, diabetes, and osteoporosis (bone loss).

Deficiency may impair formation of protein, which could lead to stunted growth, poor muscle development or loss of muscle mass, increased susceptibility to infection, weakness, and impaired wound healing.

Symptoms of potassium deficiency include loss of appetite, nausea, drowsiness, feelings of apprehension, fatigue, muscle pain and weakness (usually of the lower limbs); severe cases may lead to irregular heartbeat.

Reducing the number of probiotic organisms in the gastrointestinal tract may decrease the body's ability to resist infections and diseases. Symptoms of deficiency include gas, abdominal distress, diarrhea, and yeast infections.

Because of the wide availability of sodium in dietary sources, deficiency is very uncommon. In the rare instances where it does occur, depleted levels have been associated with gas, nausea and vomiting, headache, memory impairment, diminished attention, muscle weakness, heart palpitations, lethargy, and confusion. Extreme cases can cause stupor, seizures, and possibly coma. The development of symptoms depends in large part on the rate of the loss of sodium.

The earliest symptom of deficiency of this nutrient is night blindness. Prolonged deficiency leads to more advanced changes in eye tissue. Other potential signs of mild to moderate deficiency include rough, dry skin, loss of appetite, loss of hair luster, brittle nails, joint pain, and possibly increased susceptibility to infection.

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.

The major symptom of vitamin K deficiency is an inability of the blood to clot properly, which may lead to excessive bleeding and a tendency to bruise easily.

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 here.
