Introduction
Living, expanding tissue makes up bones. The body continually replaces old bone with new bone grown in its place. An individual with osteoporosis experiences excessive bone loss, too little bone resorption, or both. Estrogen levels fall due to the natural process of menopause, which also affects other hormones. This might result in osteoporosis. Estrogen controls the metabolism of bones because it encourages the activity of osteoblasts, which are the cells that create new bone; it is crucial to the health of the bones.
What Is Osteoporosis?
Osteoporosis is a condition affecting the bones that occur when there is a decrease in bone mass and mineral density or when there are alterations in the composition and strength of the bone. This results in the bone's ability to resist fractures declining (broken bones).
Due to the lack of symptoms that osteoporosis frequently exhibits, the patient often does not recognize it until a bone is broken. Osteoporosis is the main factor in fractures for postmenopausal women and older men. The bone from any part of the body can fracture, although the hip, spine, and wrist, along with vertebrae, are the most commonly affected.
What Is Estrogen?
Estrogen is the primary hormonal regulator of bone metabolism in both men and women. Consequently, it is important to understand the mechanisms through which estrogen exerts its bone-protective properties. Estrogen deficit is associated with a gap between bone formation and resorption, showing that estrogen is also crucial for maintaining bone formation at the cellular level, even if an increase in bone resorption is the primary effect of estrogen loss. Direct actions of estrogen on osteoblasts, osteoclasts, and osteocytes prevent bone remodeling, reduce bone resorption, and maintain bone production, respectively. Moreover, estrogen modifies osteoblast or osteocyte and T-cell control of osteoclasts. Estrogen has been proven to prolong osteoblast longevity and suppress osteoblast death, enhancing each osteoblast's functional potential.
What Are the Causes of Low Estrogen?
Various factors affect estrogen levels. Age is one of the most crucial elements.
Throughout puberty, estrogen levels rise in both males and females. Estrogen levels fluctuate constantly in women of reproductive age due to hormonal changes during the menstrual cycle. Estrogen levels start to fall during the perimenopause, the initial phase of menopause.
Moreover, some medical problems can lower estrogen levels. Any illness that affects a woman's ovaries can cause her estrogen levels to drop. Low estrogen in men can result from the same reasons that lower testosterone. Low estrogen may result from the following medical illnesses or environmental factors:
-
Ovarian polycystic syndrome.
-
Thyroid conditions.
-
Low performance of pituitary adipose.
-
Breastfeeding.
-
Low body weight.
-
Turner syndrome-related congenital problems.
-
Chemotherapy.
-
Primary ovarian failure.
What Are the Symptoms of Low Estrogen?
Menopause-related or non-menopausal symptoms of decreased estrogen include:
-
Absence or irregular periods.
-
Lowered libido in both men and women.
-
Osteoporosis-related bone fractures.
-
High cholesterol or high triglycerides.
-
Coronary heart disease.
-
Irregular periods.
-
Hot flashes.
-
Dry vaginal discharge.
How Does Estrogen Affect Osteoporosis?
Estrogen is crucial for maintaining healthy bone structure. Osteoporosis and porous weaker bones can result from decreased estrogen levels. Tissue that is alive and developing makes up bones. The body continually replaces old bone with new bone by decomposing the former.
A person with osteoporosis experiences excessive bone loss, insufficient bone resorption, or both. The natural process of menopause causes the levels of several hormones, including estrogen, to drop, which can result in osteoporosis. A person may lose bone density when estrogen levels fall, as happens after menopause, for instance. This increases the possibility of fractures by making their bones brittle and brittle.
How to Prevent Osteoporosis?
There are several ways to stop bone loss, such as:
-
Consuming vitamin D and calcium-rich meals.
-
Supplementing with calcium and vitamin D.
-
Frequently engaging in weight-bearing activities, including walking, jogging, and skipping.
-
Exercising resistance, such as lifting weights or doing push-ups.
-
Avoiding smoking and consuming excessive amounts of alcohol.
-
Obtaining vitamin D from brief exposure to sunlight.
What Is Estrogen Replacement Therapy?
-
Some individuals utilize estrogen replacement therapy (ERT) to prevent or treat osteoporosis. Estrogen replacement therapy includes ingesting synthetic estrogen to raise the body's estrogen levels.
-
Those who have undergone menopause or had their ovaries removed may be prescribed estrogen replacement therapy by their doctors. The procedure helps reduce bone loss and menopausal symptoms like hot flashes and sleeplessness.
-
Estrogen replacement therapy is available as a patch or tablet. A physician might advise twice-weekly skin patch use or daily pill intake. The progesterone hormone may also be taken as part of the treatment.
What Are the Risk and Consideration With Estrogen Replacement Therapy?
Following menopause, estrogen replacement therapy helps prevent bone loss. If a physician proposes this course of action, they will probably advise using the lowest effective dosage for the shortest period.
Some of the risks associated with estrogen replacement therapy are:
-
Heart attack.
-
Breast cancer.
-
Mental impairment.
-
Stroke.
-
Blood clots.
Conclusion
In the growth and homeostasis of bones, estrogen is primarily responsible. Osteoclastic bone resorption in women is usually accelerated by estrogen shortage following menopause. Estrogen suppresses the activation of bone remodeling and the beginning of new basic multicellular units (BMUs), two of the three main effects it has on bone metabolism. It prevents differentiation and encourages osteoclasts to commit suicide, which lowers bone resorption and while estrogen inhibits early mesenchymal progenitors' ability to regenerate themselves, it organizes osteoblastic cells' commitment to differentiation and prevents death. As a result, bone production is maintained at the cellular level. The accelerated phase in women, which was thought to involve an unproportional loss of trabecular bone, was thought to be most noticeable in the first three to five years following menopause. A crucial component of metabolism is estrogen. It encourages osteoblasts, which are bone-making cells, to become more active. Low estrogen levels are associated with an increased risk of osteoporosis and fractures. People can avoid bone loss by making lifestyle adjustments and, in some instances, taking medication.
