Symptoms
By Mayo Clinic staffIf you have hypercalcemia, you may have few or no signs and symptoms, particularly if your hypercalcemia is mild. More severe hypercalcemia symptoms may include:
- Nausea and vomiting
- Loss of appetite
- Excessive thirst
- Frequent urination
- Constipation
- Abdominal pain
- Muscle weakness
- Muscle and joint aches
- Confusion
- Lethargy and fatigue
The amount of excess calcium in your blood isn't necessarily related to the severity of your signs and symptoms. For example, older people are more likely to have pain and weakness in their muscles.
When to see a doctor
Contact your doctor if you develop signs and symptoms that may indicate hypercalcemia, such as being extremely thirsty, urinating frequently and having abdominal pain.
