Understanding Osteoporosis: Causes, Symptoms, and Treatment Options

What is Osteoporosis?

Osteoporosis is a metabolic bone disease characterized by decreased bone mass and skeletal fragility, leading to an increased risk of fractures. The term "osteoporosis" often referred to as "porous bone," reflecting the condition's impact on bone density and structure. Osteoporosis (porous bone) results in gradual bones thinning and weakening.
Decrease in bone mineral density and bone mass results in osteoporosis. It can also happen if the structure and strength of the bones change. It is largely a silent disease, meaning individuals may not realize they have it until they suffer a fracture, most commonly in the hip, vertebrae, or wrist.

Risk factors for Osteoporosis

Several factors can increase the likelihood of developing osteoporosis:

• Gender: Females are at a higher risk than males.
• Age: The risk increases significantly with advancing age.
• Body Mass Index (BMI): Lower body mass is associated with higher risk.
• Family History: A parental history of hip fractures can elevate risk.
• Lifestyle Choices: Current tobacco use, excessive alcohol consumption, and lack of physical activity can increase susceptibility.
• Medical Conditions: Conditions such as rheumatoid arthritis,untreated hyperthyroidism and type 1 diabetes,can lead to secondary osteoporosis.

Causes of Osteoporosis

Osteoporosis occurs when there is a loss of bone mass and changes in the structure of bone tissue. Key factors contributing to this condition include:

• Hormonal Changes: Lower levels of hormones, particularly estrogen in women and testosterone in men, can accelerate bone loss.
• Medications: Certain medications, such as glucocorticoids, anticonvulsants, and proton pump inhibitors, can contribute to bone density loss.
• Dietary Deficiencies: A lack of calcium and vitamin D can impede bone strength.

Pathophysiology of Osteoporosis

Osteoporosis occurs as a result of an imbalance between bone resorption and bone formation. Bone remodeling – where old bone is broken down and replaced with new bone (slows down as individuals age). This leads to a net loss of bone density, making bones more fragile and susceptible to fractures.

Signs & Symptoms of Osteoporosis

Osteoporosis typically does not present symptoms until a fracture occurs. However, once bones have weakened, signs may include:

• Back pain from a fractured or collapsed vertebra
• Loss of height over time
• A stooped posture
• Fractures occurring with minimal trauma

Diagnostic Test & Investigations

Diagnosis of osteoporosis is primarily achieved through a bone density test, known as a DEXA scan. This imaging test uses low-level X-rays to measure the mineral content and density of bones. The test is non-invasive and typically performed on an outpatient basis.

Treatment of Osteoporosis

Treatment of osteoporosis aims to slow bone loss and prevent fractures. Recommended strategies include:

Lifestyle Changes

• Nutrition - Ensure adequate intake of calcium and vitamin D.
• Exercise - Engaging in weight-bearing and strength-training exercises.
• Smoking Cessation to improve bone health.
• Moderate Alcohol Consumption

Pharmacological Treatments

• Bisphosphonates:Medications like alendronate and risedronate help preserve bone density.
• Receptor Activator of Nuclear factor Kappa-B Ligand (RANKL Inhibitors:)Denosumab is effective in treating osteoporosis in postmenopausal women and men at high risk for fractures.
• Selective Estrogen Receptor Modulators (SERMs):Raloxifene can help improve bone density in postmenopausal women.
• Anabolic Therapies:Medications like teriparatide and abaloparatide promote new bone formation.

Nursing Management of Osteoporosis

These measures are crucial for the optimal care of individuals affected by Osteoporosis

• Give balanced diet (but not too high in protein)
• Exposure to sunlight for vitamin D
• Give foods high in calcium and vitamin D (from dairy products)
• Encourage patient to take in enough fluids (about 2500 - 3000mls/day)
• Discourage patient from taking carbonated drinks (thought to contain phosphorus which is linked to bone reabsorption)

• Monitor for side effects of medications example, Prednisolone and report promptly.
• Check client's skin for redness, warmth and new sites for pain (possible indication of fracture)
• Serve drugs as prescribed for example, estrogen replacement of postmenopausal levels and testosterone to increase bone mass.
• Serve calcium gluconate plus vitamin D and Prednisolone as prescribed

• Teach patient healthy habits related to lifestyle example avoidance of alcohol, caffeine and stress Encourage exercise for patients and other persons
• Explain the value of walking daily to provide for strong bone remodeling
• Encourage patient and persons to observe good personal hygiene (hand washing)
• Teach patient on body mechanics (that is stoop before lifting object)
• For female patients on estrogen, explain to them to have regular gynecological check - ups and report any abnormal bleeding. Again to have self - examination on the breast at least 2 times in a month
• Encourage patient and family to adhere to prescribed medication
• Participate in dietary education related to vitamin D intake
• Encourage regular exercise for patient (especially weight bearing exercise)
• Provide information in relation to adequate daily intake of 800mg or more calcium
• Instruct persons with history of urinary tract calculi to consult his/her physician before increasing calcium intake
• Advise patient to sleep on a firm mattress but to avoid excessive rest
• Thoroughly explain osteoporosis to patient and family members.

• Move patient gently and carefully at all times
• Explain to the family and other paramedics how easily the patient's bone can fracture
• Ensure dry and well mop floor to prevent accidental falls especially in the elderly

• Ensure range of motion exercises for patient hospitalized
• Recommended regular weight bearing exercise to your patient (if indicated to prevent bone loss)
• Instruct patient to exercise within his/her range/limit.
• Daily walking, jogging and stair climbing to improve general wellbeing of client

Preventions of Osteoporosis

While osteoporosis cannot be completely prevented, the following measures can help reduce the risk:

• Maintain a balanced diet rich in calcium and vitamin D
• Engage in regular physical activity, particularly weight-bearing exercises
• Avoid smoking and limit alcohol consumption
• Safety Precautions – Take steps to prevent falls, such as decluttering living spaces and wearing appropriate footwear
