Symptoms of excess calcium in the body

A slight rise in calcium in the body does not cause any symptoms to the patient, but when it rises at high levels, some symptoms appear, including:[1]

  • Excessive thirst and frequent urination: Excess calcium makes the kidneys work harder, leading to dehydration and a feeling of extreme thirst.
  • Stomach pain and digestive problems: Excess calcium in the body can lead to digestive problems such as abdominal pain, nausea, vomiting, and constipation.
  • Bone pain and muscle weakness: When calcium increases in the body, the bones excrete the excess in the blood, causing bone pain and muscle weakness.
  • Feeling of confusion and general fatigue: These symptoms appear as a result of the various effects of an increase in calcium in the brain.
  • Anxiety and depression: Excess calcium affects mental health.
  • Increased blood pressure and heart arrhythmia: An increase in calcium in the body leads to an electrical imbalance in the heart, and thus an irregular heartbeat.

Treatment of excess calcium in the body

In the case of a slight increase in calcium in the body, bone health and kidney function are monitored and their safety is checked over time. In some cases, some types of medications are dispensed, including: [2]

  • Calcitonin: This hormone is extracted from salmon, and helps control calcium levels, and one of its side effects is a mild feeling of nausea.
  • Calcium analogues: These medications are used to control high calcium levels in the body and are effective medications for hyperparathyroidism.
  • Bisphosphonates: These are drugs used to treat osteoporosis. These drugs are often given intravenously to cancer patients who suffer from high calcium, and this treatment has caused necrosis of the jaw bones, and hip fractures.
  • Denosumab: This treatment is given to cancer patients who have high blood calcium levels after treatment with bisphosphonates has failed.
  • Prednisone: This drug contributes to treatment if it is used in the short term, and it is a type of cortisone medication, and it is used in the event that high vitamin D in the body causes calcium to rise.
  • Intravenous fluids and diuretics: If calcium rises in the body in very large proportions, it is recommended to transfer the patient to the hospital to be given intravenous fluids and diuretics, for fear of calcium’s effects on the heart and nervous system.

Causes of high calcium in the blood

Calcium, vitamin D, and parathyroid hormones contribute to regulating calcium levels in the blood, and parathyroid hormones control the amount of calcium that is transferred to the blood from the intestines, kidneys, and bones, and the proportion of these hormones increases when calcium levels drop in the blood, and one of the most important causes of To increase the proportion of calcium in the body:[3]

  • Overactive parathyroid glands.
  • Lung problems and some types of cancer.
  • Side effects of some types of medicines.
  • Diet and the use of nutritional supplements.
  • Drought.
