Premenopausal women with primary hyperparathyroidism (PHPT) generally present with more severe symptoms and biochemical markers. However, postmenopausal PHPT cases are increasing, indicating a growing concern in this demographic.
Area of Science:
- Endocrinology
- Women's Health
- Metabolic Bone Disease
Background:
- Primary hyperparathyroidism (PHPT) is a common endocrine disorder, particularly in postmenopausal women.
- Understanding demographic and clinical differences is crucial for effective management.
Purpose of the Study:
- To compare demographic, clinical, and biochemical characteristics of premenopausal and postmenopausal women with PHPT.
- To analyze trends in PHPT prevalence based on menopausal status.
Main Methods:
- Retrospective analysis of women with PHPT from an Indian registry (2005-2019).
- Comparison of premenopausal (pre-M) and postmenopausal (post-M) patient cohorts.
Main Results:
- Premenopausal women had higher rates of symptomatic disease, osteitis fibrosa cystica, higher PTH, and alkaline phosphatase levels.
- Postmenopausal women showed increased prevalence of hypertension and gallstone disease.
- A significant increase in postmenopausal PHPT cases was observed between 2015-2019 compared to 2005-2009.
Conclusions:
- While PHPT is more prevalent in premenopausal women, postmenopausal cases are rising.
- Premenopausal women typically exhibit more severe clinical and biochemical manifestations of PHPT.

Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...
Hormones and Bone Tissue
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Bone Remodeling
Menopause
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
