osteoporosis Flashcards
What causes osteoporosis?
Fracture attributable to OP is a significant health problem that women face, especially after menopause. As estrogen and progesterone levels fall, bone strength also declines.
During adult hood and adolescent, low bone mass and OP are caused when the normal processes of bone remodeling are unbalanced and resorption rates exceed bone formation,
Osteoporosis and Osteopenia
Osteopenia is similar to OP except that there is a lesser amount of bone lost.
Two factors contribute to bone strength:
bone mineral density (BMD) and bone quality.
Bone mineral density
BMD refers to the thickness and volume of the bone.
What is bone quality
Bone quality refers to the bone architecture, mineralization, rate of turnover, and accumulated damage
. Cannot be easily measured.
BMD is easily measured using densitometry testing such as the …………………………
dual-energy x-ray absorptiometry (DEXA).
What is kyphosis
Kyphosis causes a permanently stooped appearance, and may be recognized when a woman has a documented loss of height.
What are the impact of kyphosis
Kyphosis also causes the rib cage to slump downward, eventually coming to rest on the ischial spines, thus minimizing thoracic and abdominal cavity space for organs.
This restriction frequently leads to gastrointestinal problems, such as gastric reflux, anorexia, and constipation, and to respiratory disorders, such as shortness of breath.
Self-image can also be negatively affected because of body changes and difficulty in finding clothing that fits properly over the kyphotic deformity.
what is osteoporosis?
OP is defined by BMD at the hip or lumbar spine that is 2.5 or more standard deviations below the mean BMD of a young-adult reference population
.
what is the difference between secondary and primary OP?
Primary OP occurs because of causes related to age, gender, and family history. It occurs with aging and accelerates in women at menopause. EG. Low BMD at the femoral neck (T-score of −1.0 or below) is found in 21% of postmenopausal (PM) White women,
Secondary OP results from medical conditions or treatments that interfere with the attainment of peak bone mass and/or that may predispose to accelerated bone loss requiring long-term corticosteroid therapy, an increasing list of dietary, lifestyle, endocrine, metabolic, and other causes of bone mass deterioration have been identified, such as smoking, sedentary lifestyle/low physical activity, Cushing’s disease, diabetes, hyperthyroidism, and pregnancy
Is osteoporosis painful?
.
OP is the most common bone disease, yet it is painless and often remains undiagnosed until a fracture occurs
why primary OP is caused more in female?
Primary OP is associated with aging and affects women more than men because of the rapid increase in bone loss that accompanies the decline in estrogen and progesterone levels during the menopausal transition

Does Secondary Op effect males and female?
secondary OP can affect males or females at any age.
Risk factors of OP?
Potentially Modifiable Risk
Factors Amenorrhea (caused by eating disorder or excessive exercise) Body weight less than 127 pounds, body mass index less than 21 kg/m2 Chronic diseases
Cigarette smoking (active or passive)
Frailty Low estrogen level (e.g., menopause)
Medications
Nulliparity
Poor nutrition (e.g., excessive vitamin A, excessive alcohol or caffeine intake, excessive soda intake, excessive sodium intake, inadequate calcium/vitamin D intake, protein deficiency) Sedentary lifestyle
Nonmodifiable Risk Factors Advanced age Dementia Delayed puberty Endocrine disorders (Cushing’s, thyrotoxicosis, diabetes mellitus) Family history of OP Female gender First-degree relative with history of fracture Fracture history (fracture at 40–45 years or older is associated with an increased risk for osteoporosis) Genetic factors (variations in or absence of genes that regulate protein receptors or enzymes needed for bone development) Race (Caucasian and Asian women at greatest risk, then Hispanic and African American)
Other risk factors for OP?
Age (especially greater than 65 years, fracture risk doubles with each 7–8 years after 50 years) Current smoking Femoral neck raw bone mineral density (BMD) in g/cm2 Glucocorticoid use Body mass index (BMI) (height and weight, BMI less than 21 kg/m2) Parent history of hip fracture (increases risk ~130%) Personal prior fracture (risk for future fracture doubles) Rheumatoid arthritis Secondary OP Gender (females at greater risk than males)
Weakness History of falls, fainting, off balance Poor vision Neuropathy, especially lower extremities Vertigo Impaired mobility Use of medications or substances that cause drowsiness, dizziness, lightheadedness, or imbalance; use of multiple medications Neurologic disease Frailty Orthostatic hypotension Low vitamin D levels Sedentary lifestyle, Depression
