A low level of calcium in the body is a medical condition known as hypocalcemia. A patient can have unusually low calcium levels for a variety of reasons, including hormonal problems, Vitamin D deficiency, kidney dysfunction or poor calcium consumption. Many patients with hypocalcemia do not experience noticeable side effects. Patients who develop effects of hypocalcemia should talk with a doctor for further evaluation and care.
Muscle Tremors or Seizures
Calcium is a naturally-occurring compound that is involved in regulating normal muscle contraction in the body. Unusually low levels of calcium in the blood can cause affected patients to experience involuntary muscle tremors or seizures as an effect of this condition, according to Children's Hospital of Pittsburgh. These effects of hypocalcemia can occur in conjunction with muscle stiffening or spasms, a condition called tetany. Affected patients may also experience sensations of pain, cramping or aching within the muscles. Muscle-related effects of hypocalcemia can persist or become worse until a patient receives treatment.
Mood Changes
Persistently low levels of calcium in the body can cause unusual mood-related changes to arise in patients. These effects of hypocalcemia can include depression, memory loss or anxiety, warns the Cleveland Clinic. Additionally, children with abnormally low levels of calcium in the body can experience growth delays or mental retardation as effects of this condition. Certain patients with hypocalcemia may also experience hallucinations, delirium or confusion.
Breathing Difficulties
Muscle spasms in the throat can lead to breathing difficulties in patients who have hypocalcemia, explains the Merck Manuals Online Medical Library. Affected patients can begin to wheeze or may develop shortness of breath. These serious effects of low calcium in the body should be reported to a doctor immediately.
Tingling or Numbness
Over time, patients with hypocalcemia can develop a tingly sensation within their feet, fingers or mouth, explains Merck Manuals. Sensations of tingling or numbness can make it difficult for patients to move the affected body region normally. These sensations can be uncomfortable and may become worse if treatment for hypocalcemia is not promptly received.
Heart Rate or Blood Pressure Abnormalities
Hypocalcemia can lead to heart-related effects in certain patients. Calcium is involved in regulating when the heart muscle contracts or beats. Abnormally low calcium levels can cause heart rate abnormalities or unusually low blood pressure, explains the Cleveland Clinic. Patients with extremely low levels of calcium may also be at an increased risk of developing congestive heart failure. Patients who develop any heart rate changes for any reason should contact a physician immediately.
