GENERAL HISTOLOGY

Detailed explanation-1: -Familial hypocalciuric hypercalcemia (FHH) causes lifelong hypercalcemia with features that overlap with typical primary hyperparathyroidism (PHPT). The incompleteness of this overlap has led to divergent nomenclatures for FHH.

Detailed explanation-2: -The main causes of hyperthyroidism are Graves’ disease, toxic multinodular goitre, and toxic adenoma. About 20 times more women than men have hyperthyroidism.

Detailed explanation-3: -Conclusion: The calcium:creatinine clearance ratio (CCCR) is the consensus biochemical test to differentiate between PHPT and FHH. However, this test is still limited by a considerable indeterminate range, and definitive diagnosis of FHH requires genetic testing.

Detailed explanation-4: -Hyperthyroidism happens when the thyroid gland makes too much thyroid hormone. This condition also is called overactive thyroid. Hyperthyroidism speeds up the body’s metabolism. That can cause many symptoms, such as weight loss, hand tremors, and rapid or irregular heartbeat.
