Hyperparathyroidism is an important clinical condition with severe consequences if it is not well diagnosed and treated. Knowledge of calcium metabolism is essential for the correct management of the patient with the disease. Primary hyperparathyroidism, although oligosymptomatic in most patients, should be viewed with magnitude by general practitioners with a basic health approach. The patient with hyperparathyroidism secondary to chronic kidney disease, often with several associated comorbidities, needs the best possible approach, directly influencing his quality of life, improving cardiovascular and osteometabolic status.
