Causes and symptoms of hyperparathyroidism
There are two main types of hyperparathyroidism: primary and secondary. Primary hyperparathyroidism occurs when one or more of the parathyroid glands develop a benign tumour, known as an adenoma, which causes excessive PTH production.
Secondary hyperparathyroidism is a result of other medical conditions, such as kidney disease or vitamin D deficiency, that lead to low calcium levels in the body and stimulate the parathyroid glands to produce more PTH.
Symptoms of hyperparathyroidism can vary depending on the severity of the condition. Some people may not experience any symptoms, while others may suffer from fatigue, muscle weakness, bone pain, and joint pain. Other common symptoms include frequent urination, kidney stones, constipation, abdominal pain, nausea, vomiting, and loss of appetite. In severe cases, hyperparathyroidism can lead to confusion, memory loss, and depression.
