Hyperparathyroidism is classified into primary hyperparathyroidism, secondary hyperparathyroidism and triple hyperparathyroidism depending on its cause. In most cases, primary hyperparathyroidism is caused by genetic mutations. Depending on the specific type of pathology and the type of mutation, it is divided into adenomas, hyperplasia, adenocarcinoma and multiple neuroendocrine tumors, etc. Among them, single adenomas account for about 80%. No direct relationship has been found between hyperparathyroidism and food and other factors.
