What symptom is a hallmark of hyperparathyroidism?

In hyperparathyroidism, one of the hallmark symptoms is indeed constipation. This condition leads to elevated levels of parathyroid hormone, which in turn increases calcium levels in the blood (hypercalcemia). High calcium levels can affect various bodily functions, including the gastrointestinal tract, leading to slowed intestinal motility and, consequently, constipation.

Individuals with hyperparathyroidism may experience a range of other symptoms due to the high calcium levels in the body, but constipation is particularly prevalent and can often be one of the first signs noticed by patients. It is important to recognize this symptom as a clue to potential underlying hormonal imbalances that require further evaluation and management.
