Primary hyperparathyroidism is often diagnosed before signs or symptoms of the disorder occur. This is usually because an elevated level of calcium is found on routine blood tests. When symptoms do occur, they're the result of damage or dysfunction in other organs or tissues. This damage or dysfunction is due to high calcium levels in the blood and urine or too little calcium in bones. Symptoms may be so mild and nonspecific that they don't seem related to parathyroid function, or they may be severe. The range of signs and symptoms include:  Weak bones that break easily (osteoporosis) Kidney stones Excessive urination Stomach (abdominal) pain Tiring easily or weakness Depression or forgetfulness Bone and joint pain Frequent complaints of illness with no clear cause Nausea, vomiting or loss of appetite
