Blood Calcium Levels - Hypocalcemia vs. Hypercalcemia: In order for the heart and muscles to function properly, as well as to ensure bone development, normal blood calcium levels are essential. When the blood has too little calcium levels, the condition is known as hypocalcemia. In contrast, hypercalcemia is a condition in which the calcium levels in the blood are above normal. Too much or too little of calcium in the blood can weaken bones, create kidney stones, and interfere with proper heart and brain function.

Blood Calcium Levels - Hypocalcemia Symptoms
- Short stature
- Dry skin and hair
- Brittle nails
- Muscle cramps or spasms
- Tingling in the fingers and toes
- Weakened tooth enamel
Blood Calcium Levels - Hypercalcemia Symptoms
- Excessive thirst and frequent urination due to kidneys working harder to filer the excess calcium in the blood.
- Upset stomach, nausea, vomiting and constipation
- Bone pain, muscle weakness, lethargy, and fatigue
- Confusion and depression caused by the interference with the way the brain works.
- Palpitations and fainting, indications of cardiac arrhythmia, and other heart problems due to the interference with the heart function.
Blood Calcium Levels - Hypocalcemia Causes
- Maternal diabetes
- Medications that suppress the parathyroid gland
- Vitamin D deficiency
- Hypoparathyroidism - Parathyroid hormone (PTH) regulates the amount of calcium and phosphorus in bone and blood. With hypoparathyroidism, blood calcium levels fall.
- Cancer of the thyroid
- Hypomagnesmia – When magnesium levels are low, calcium levels in the blood decrease as well
Blood Calcium Levels - Hypercalcemia Causes
- Hyperparathyroidism - overactive parathyroid glands
- Tuberculosis and sarcoidosis can raise blood levels of vitamin D, which stimulates your digestive tract to absorb more calcium.
- Immobility -bones that don't bear weight release calcium into the blood.
- Severe dehydration causes a rise in calcium concentrations in the blood.
- Medications might increase the release of parathyroid hormone (PTH).
- Supplements of calcium or vitamin D over time can raise calcium levels in the blood above normal.
