Sure, here is a presentation on Osteoporosis:

• Affiliation (if applicable)

Speaker Notes Good morning/afternoon everyone. Today we’ll be discussing osteoporosis, a common bone disease that weakens bones and increases the risk of fractures.

Slide 2

What is Osteoporosis?

• A chronic metabolic bone disease
• Characterized by low bone mineral density (BMD) and deterioration of bone microarchitecture
• Increases susceptibility to fragility fractures

Speaker Notes Osteoporosis is a disorder that affects the quality and density of our bones. It is a chronic condition, meaning it’s long-term and progressive. In healthy bones, a balance exists between bone formation and resorption (breakdown). In osteoporosis, this balance is disrupted, leading to a net loss of bone tissue, making them more fragile and prone to fractures, even from minor falls.

Pathophysiology of Osteoporosis

• Bone Remodeling: Continuous process of bone breakdown (resorption) by osteoclasts and formation (synthesis) by osteoblasts
• Osteoporosis disrupts this balance, leading to excessive resorption and insufficient formation

Speaker Notes Our bones are constantly undergoing remodeling, a process where old bone is broken down by osteoclasts and replaced with new bone formed by osteoblasts. In osteoporosis, this delicate balance is disrupted. Osteoclasts become overactive, breaking down bone faster than osteoblasts can rebuild it. This leads to a net loss of bone mass and deterioration of bone microarchitecture, the internal structure of bone, making them weaker.

Risk Factors for Osteoporosis

• Age: Risk increases with age, especially after menopause in women and over 50 in men
• Sex: Women are at greater risk due to hormonal changes after menopause
• Family history: Having a close relative with osteoporosis increases risk
• Ethnicity: White and Asian populations are at higher risk
• Diet: Low calcium and vitamin D intake weakens bones
• Lifestyle factors: Inactivity, smoking, and excessive alcohol consumption contribute
• Medical conditions: Certain medical conditions and medications can increase risk.

Speaker Notes Several factors can increase one’s risk for osteoporosis. Age is a major risk factor, with the risk increasing significantly after menopause in women and over 50 in men. Women are generally at greater risk due to hormonal changes associated with menopause. Genetics also plays a role, with a family history of osteoporosis increasing the risk. Ethnicity also matters, with white and Asian populations having a higher risk. A diet low in calcium and vitamin D, essential for bone health, weakens bones. Lifestyle factors like physical inactivity, smoking, and excessive alcohol consumption contribute to bone loss. Certain medical conditions and medications can also increase the risk.

Clinical Manifestations of Osteoporosis

• Osteoporosis is often called a “silent disease” because it usually has no symptoms until a fracture occurs
• Common fractures include those of the hip, spine (vertebral compression fractures), and wrist

Speaker Notes Osteoporosis is often dubbed a “silent thief” because it often progresses with minimal to no symptoms until a fracture occurs. This is why regular bone density scans are crucial for early detection. The most common fractures associated with osteoporosis are those of the hip, which can be debilitating and life-threatening, spine (vertebral compression fractures) which can cause back pain and loss of height, and wrist fractures.
