Hormonal influences on osteoporosis.

M J McKenna, B Frame

    The American Journal of Medicine
    |January 26, 1987
    PubMed
    Summary

    Osteoporosis causes over a million fractures annually in the US, costing billions. Understanding bone physiology and risk factors like hormone deficiency is crucial for prevention and treatment.

    Area of Science:

    • Bone physiology and pathophysiology
    • Endocrinology
    • Gerontology

    Background:

    • Osteoporosis leads to over one million fractures annually in the U.S., incurring significant healthcare costs.
    • Bone structure comprises compact cortical and porous trabecular bone, maintained by osteoblasts and osteoclasts.
    • Factors like sex hormone deficiency, chronic illness, and malnutrition negatively impact bone mass.

    Purpose of the Study:

    • To discuss the physiology and pathophysiology of bone tissue in relation to osteoporosis.
    • To explore the role of sex hormones, particularly estrogen, in bone health.
    • To identify risk factors contributing to osteoporosis development.

    Main Methods:

    • Review of current literature on osteoporosis, bone physiology, and hormonal influences.
    • Analysis of the structural components of bone and cellular processes involved in bone remodeling.
    • Examination of the impact of hormonal deficiencies and other risk factors on bone mass.

    Main Results:

    • Osteoporosis is a significant public health issue with substantial economic impact.
    • Bone remodeling involves a balance between osteoblast and osteoclast activity.
    • Estrogen deficiency is linked to reduced bone mass, though mechanisms require further study.

    Conclusions:

    • Osteoporosis results from a complex interplay of hormonal, nutritional, and environmental factors.
    • Estrogen plays a protective role in the female skeleton, potentially mitigating bone loss.
    • Further research is needed to understand susceptibility to estrogen deficiency and the role of other hormones.
