Side Effects Of Lack Of Calcium

Calcium is the most abundant mineral in the human body. Apart from strengthening the bones and teeth, it is also essential for the contraction and dilatation of the blood vessels, transmission of nerve impulses, intracellular signaling and muscle function. The Institute of Medicine recommends up to 1300 mg of calcium per day depending upon the gender and the age of the individual. Dairy products, oranges, salmon, spinach and broccoli are good dietary sources of calcium. Supplements may also be prescribed to treat a calcium deficiency.

Bone Loss

Almost 99 percent of the calcium in your body is stored in your bones and teeth. Its deficiency due to inadequate intake or poor absorption may lead to accelerated bone loss and osteoporosis. Calcium from your bones may also be reabsorbed into the blood due to the hormonal changes that happen in women after menopause. Along with other medications, calcium and vitamin D supplements may be prescribed to reverse bone loss. The supplements, however, are associated with a variety of side effects, including kidney stones, and they should not be used without consulting a doctor.

Muscle Cramps

Muscle cramps are the painful contractions of the muscles that commonly affect the thighs and lower calf. Calcium plays a major role in the biochemical processes that cause contraction of muscles, and lack of calcium is one of the common causes of muscle cramps.

Hypertension

Calcium also balances the ionic channels that are responsible for the contraction and dilatation of blood vessels. Lack of calcium may, therefore, affect blood flow. A study published in the April 2008 edition of the journal "Hypertension" revealed that low-fat dairy products and calcium supplements may reduce the risk of high blood pressure in middle-aged and older women.

Nervous System Disorders

Calcium plays an important role in the intracellular communication within the nervous system. Lack of calcium may, therefore, affect the normal functioning of the brain. In fact, according to Mitchell Bebel Stargrove, author of the book "Herb, Nutrient, and Drug Interactions," calcium deficiency may lead to anxiety, depression, insomnia and convulsions. It can also cause neuromuscular irritability and numbness in the fingers and toes. If you are experiencing these symptoms, talk to a doctor before taking calcium supplements, as they may be due to other causes.
