Amenorrhea may herald the onset of estrogen deficiency, which can adversely affect peak bone mass and ultimate risk of osteoporosis. Recent findings: Adolescence is a critical period for bone accretion.
What is osteoporosis and amenorrhea?
Abstract. Osteoporosis is widely accepted as a “female disease” occurring primarily in postmenopausal women. The fact that this disease can affect premenopausal women experiencing menstrual dysfunction is less commonly known. Amenorrhea decreases bone density at an age when bone formation should still be occurring.
Can prolonged amenorrhea can lead to osteoporosis?
Prolonged amenorrhea can result in early bone loss and increased risk of osteoporosis. Amenorrhea occurs naturally in some women who are breast-feeding, but in these circumstances it does not put the bones at risk.
What are the effects of amenorrhea on bone mineral?
Hyperprolactinemic amenorrhea was the first identified model of functional hypogonadal osteoporosis and is associated with a 17% decrease in cortical (20) and a 15–30% decrease in trabecular (21–23) bone density.
How does menstruation affect bone density?
Loss of menstrual regularity has been associated with an increased risk of wrist and hip fractures related to reduced bone density, even without the development of amenorrhea. A later menarche and menstrual cycle intervals longer than 32 days have both been associated with increased fracture rates in later years.
How does estrogen affect osteoporosis?
Estrogen, a hormone in women that protects bones, decreases sharply when women reach menopause, which can cause bone loss. This is why the chance of developing osteoporosis increases as women reach menopause.
Can no period cause osteoporosis?
Irregular Periods in Young Women Could be Warning Sign for Later Osteoporosis. Irregular menstrual periods in young women may be a warning sign of a hormonal shortage that could lead to osteoporosis, according to a preliminary study by researchers at the National Institute of Child Health and Human Development (NICHD).
Does the pituitary gland affect your period?
Brain structures called the hypothalamus and pituitary gland control the menstrual cycle. The hypothalamus triggers the pituitary gland to make hormones that trigger the ovaries to make oestrogen and progesterone.
How does anorexia cause osteoporosis?
The link between anorexia nervosa and osteoporosis
Low estrogen levels contribute to significant losses in bone density. In addition, individuals with anorexia often produce excessive amounts of the adrenal hormone cortisol, which is known to trigger bone loss.
Why do female athletes experience amenorrhea?
Amenorrhoea is the absence of menstrual periods. Women who are elite athletes or who exercise excessively on a regular basis are at risk of developing athletic amenorrhoea. Causes are thought to include low levels of body fat and the effects of exercise-related hormones on the menstrual cycle.
Do you lose calcium during your period?
In the present study, the mean serum calcium levels increased by 5.61% in the follicular phase as compared to the menstrual phase and decreased by 7.86% in the luteal phase.
Are bones weaker on period?
“What it really signals is that there is not enough energy available to support normal reproductive hormonal fluctuations. These hormonal changes are tied to development of bone mass. Without them, bones become weak, and injuries are a risk.”
Who is at risk for developing a calcium deficiency?
There are three major population groups that are at highest risk for dietary calcium deficiency. These include women (amenorrheic, the female athlete triad, postmenopausal), individuals with milk allergy or lactose intolerance, and atrisk groups for dietary deficiency intake (adolescents and the elderly).
