Osteoporosis

From iWiki

Osteoporosis is a medical condition characterized by the weakening of bones, leading to increased bone fragility and a higher risk of fractures. It is a common skeletal disorder that primarily affects older individuals, especially postmenopausal women, but can also occur in men. Osteoporosis is often referred to as a "silent disease" because it progresses without noticeable symptoms until a fracture occurs.

Overview

Osteoporosis is a systemic skeletal disorder that results in a decrease in bone mass and deterioration of bone tissue. As bones become porous and brittle, the risk of fractures, especially in the spine, hip, and wrist, significantly increases.

Causes and Risk Factors

Causes:

Aging: Bone density naturally decreases with age.

Hormonal Changes: Postmenopausal women experience a decline in oestrogen levels, which accelerates bone loss.

Nutritional Deficiencies: Inadequate intake of calcium and vitamin D.

Genetics: Family history of osteoporosis increases the risk.

Medical Conditions: Conditions such as rheumatoid arthritis and hormonal disorders.

Medications: Long-term use of certain medications, such as glucocorticoids.

Risk Factors:

Gender: Women are at a higher risk, especially after menopause.

Age: The risk increases with age.

Body Weight: Low body weight is associated with lower bone mass.

Ethnicity: Caucasians and Asians are at a higher risk.

Lifestyle Factors: Lack of physical activity, smoking, excessive alcohol consumption.

Symptoms

Osteoporosis is often asymptomatic until a fracture occurs. Common symptoms include:

Back Pain: Due to fractures or collapsed vertebrae.

Loss of Height: Compression fractures in the spine may lead to a stooped posture.

Bone Fractures: Fragility fractures, especially in the hip, spine, and wrist.

Diagnosis

Bone Density Testing:

Dual-Energy X-ray Absorptiometry (DXA): Measures bone mineral density.

Quantitative Computed Tomography (QCT): Provides detailed images of bone density.

Peripheral Dual-Energy X-ray Absorptiometry (pDXA): Portable device for screening.

Prevention and Treatment

Prevention:

Adequate Nutrition: Ensure sufficient intake of calcium and vitamin D.

Weight-Bearing Exercise: Regular physical activity helps maintain bone density.

Healthy Lifestyle: Avoid smoking and limit alcohol consumption.

Treatment:

Medications: Bisphosphonates, hormone therapy, and other medications may be prescribed.

Calcium and Vitamin D Supplements: Especially for those with deficiencies.

Physical Therapy: Exercises to improve strength and balance.

Complications

Fractures: Increased risk of fractures, especially in the hip, spine, and wrist.

Loss of Independence: Severe fractures can lead to a loss of mobility and independence.

Conclusion

Osteoporosis is a common condition characterized by weakened bones and an increased risk of fractures, particularly in older individuals. Early diagnosis, lifestyle modifications, and appropriate medical interventions can help manage the disease and reduce the risk of complications.
