What type of osteoporosis is primarily associated with postmenopausal women?

Type I osteoporosis, also known as postmenopausal osteoporosis, is primarily associated with women after menopause due to estrogen deficiency. Estrogen plays a significant role in maintaining bone density by inhibiting osteoclast activity, which are the cells responsible for bone resorption. After menopause, the drop in estrogen levels leads to increased bone resorption, resulting in a net loss of bone mass.

This type of osteoporosis typically presents with vertebral and wrist fractures, as these areas are highly affected by the loss of trabecular bone, which is more prominent in women during the postmenopausal period. The rapid rate of bone loss during the first few years after menopause distinguishes Type I osteoporosis from other forms.

Type II osteoporosis, which is often referred to as senile osteoporosis, tends to affect both men and women later in life, typically beyond the age of 70, and is attributed to age-related factors and decreased intake or absorption of calcium.

Primary osteoporosis refers to osteoporosis that occurs without a specific underlying disease but includes both Type I (postmenopausal) and Type II (age-related) forms. Secondary osteoporosis occurs as a result of specific medical conditions or medications that affect bone health, such as thyroid disease or long-term steroid use.
