Correct answer is option 'D'. Can you explain this answer?

Answer

Answer is d.bcoz osteoporosis is a disease which happens with increasing age and remaining all three options are wrong like first option in which  myasthenia gravis disease is not an autoimmune disease.i hope u like it...

Answer

Answer

Statement D: Osteoporosis - decrease in bone mass and higher chances of fractures with advancing age.

Osteoporosis is a disorder of the skeletal system characterized by a decrease in bone mass and a higher risk of fractures, particularly in older individuals. It is a common condition and predominantly affects postmenopausal women, although it can also occur in men.

Causes and Risk Factors:
Osteoporosis occurs when the rate of bone resorption (breakdown) exceeds the rate of bone formation, leading to a loss of bone density. Several factors contribute to the development of osteoporosis, including:

1. Age: As individuals age, the rate of bone turnover slows down, making bones more susceptible to loss of density.

2. Hormonal changes: Women experience a significant drop in estrogen levels during menopause, which accelerates bone loss. In men, low testosterone levels can also contribute to osteoporosis.

3. Lifestyle factors: Lack of physical activity, poor nutrition (especially low calcium and vitamin D intake), smoking, and excessive alcohol consumption can increase the risk of developing osteoporosis.

4. Family history: Having a parent or sibling with osteoporosis increases the likelihood of developing the condition.

Symptoms:
Osteoporosis is often referred to as a 'silent disease' because it progresses without noticeable symptoms until a fracture occurs. Common symptoms can include:

1. Back pain: Compression fractures in the spine can cause chronic back pain and a stooped posture.

2. Loss of height: Multiple vertebral fractures can lead to a gradual loss of height over time.

3. Fractures: Osteoporotic bones are more fragile and prone to fractures, particularly in the hip, wrist, and spine.

Diagnosis and Treatment:
To diagnose osteoporosis, a bone mineral density (BMD) test is conducted using a dual-energy X-ray absorptiometry (DXA) scan. This test measures bone density and helps determine the risk of fracture.

Treatment for osteoporosis focuses on preventing further bone loss, reducing fracture risk, and managing pain. It typically includes:

1. Lifestyle modifications: Regular weight-bearing and muscle-strengthening exercises, along with a balanced diet rich in calcium and vitamin D, are recommended.

2. Medications: Various medications, such as bisphosphonates, hormone therapy, and selective estrogen receptor modulators (SERMs), may be prescribed to slow bone loss or promote bone formation.

3. Fall prevention: Measures to reduce the risk of falls, such as removing tripping hazards, improving lighting, and using assistive devices, are essential.

In conclusion, osteoporosis is a disorder characterized by a decrease in bone mass, leading to an increased risk of fractures. It primarily affects older individuals, particularly postmenopausal women. Early diagnosis, lifestyle modifications, and appropriate medical interventions can help manage osteoporosis and reduce the risk of fractures.
