The body converts beta carotene to vitamin A, therefore, deficiency symptoms are the same as those of vitamin A. The earliest symptom 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 increased susceptibility to infection.
Symptoms of deficiency include loss of appetite, nausea, drowsiness, feelings of apprehension, excessive thirst, irrational behavior, fatigue, muscle pain and weakness (usually of the lower limbs). Severe cases may lead to irregular heartbeat.
Sodium deficiency is rare because it is widely available in dietary sources. When 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 on the rate of sodium loss.
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 information presented here covers some of the nutrients that may be lowered when you take certain medications. The signs and symptoms listed can be caused by other conditions. If you have these signs and symptoms, it doesn't always mean you have low levels of these nutrients. Many things affect the level of nutrients, including your medical history, diet, and lifestyle, as well as how long you have been taking the medication. Please talk with your health care provider. He or she can best address your health care needs and see if you are at risk for low levels of any nutrients.
