Why is bone density important?

Why is bone density important?

For multiple reasons: Achieving the potential peak bone mass during adolescence, and maintaining it during the adulthood is very important for preventing future fractures. There are many diseases, medications, lifestyle habits, and food components can adversely affect the bone density and the bone quality leading to fragility (osteoporotic) fractures. If one takes proactive actions, most of these are preventable. ...Read more

Body Mass Index (Definition)

Body mass index (BMI) is a measurement based on a person's height and weight, to decide if a person is too heavy or too light for his height. The index is a number that can be in the underweight range, normal range, overweight range, or obese range. Children use different number ranges than adults do, ...Read more

Do painkillers affect bone density?

Do painkillers affect bone density?

No: But some medicines, notably the h2 blockers like Cimetidine and the proton pump inhibitors like esomeprazole, can reduce calcium absorption. Some studies have suggested this can lead to increased fracture risk in the long run. ...Read more

Can fluoride decrease bone density?

Can fluoride decrease bone density?

Depends on exposure: Interesting question. It has been a long standing observation that over exposure to Fluoride can lead to decrease in bone density and increased overall fracture rate, however and interestingly enough, limited exposure actually increases bone density (mainly in trabecular bone such as spine). Even so, the increased density does not correspond to increased bone strength. ...Read more

What is a ultrasonic bone density test?

What is a ultrasonic bone density test?

A DXA alternative: The dual energy x-ray analysis (dexa or dxa) is considered the "gold standard" for measuring the mineral content of your bone. A similar measurement can be done with ct-scans or ultrasound, where the impedance of the sound wave can be correlated with bone mineral. None of these tests provide much definitive information about fracture risks. Ask you doctor for a frax clinical analysis first! ...Read more

I'm confused by the bone density t score?

I'm confused by the bone density t score?

Relates to max dense: T score compares patient to age/sex/race matched individuals at age 32 (or so)-peak bone density. Relates to statistcs, bell shaped curve. Nl is (-)1 standard deviation and better (top 80+%). Low bone mass (osteopenia) (-)1.0-(-) 2.5 std dev (about #5-20 in a classof 100); osteoporosis (-)2.5 or more (bottom of the class). These vary with age, sex, race. Z score compares pt to same age, sex, race. ...Read more

How does the bone density test define osteoporosis?

How does the bone density test define osteoporosis?

Only partly: The dexa scan gives the bone mineral density at the hips, spine and forearm. These scores can predict osteoporosis: 't-score' of less than -2.5 is considered osteoporosis. However, many people suffer osteoporosis fractures despite having better bone densities. So, we also use other factors: age, ethnicity, size, family history, prior fractures, smoking, alcohol, other conditions to predict risks. ...Read more

Is there a connection between bone density drugs and cancer?

Is there a connection between bone density drugs and cancer?

As a treatment: This group of drugs is used to stabilize the bone to reduce cancer related injury to bone. They are used in solid tumors and in myeloma. They reduce bone fractures and other complications. These drugs also are used to reduce the elevated calcium that occurs in some cancer patients. ...Read more

What is the difference between a DEXA bone density scan and x-ray?

Dose and accuracy: The dexa uses a very small dose of x-ray compared to a regular x-ray and it is designed to measure density not produce a high quality picture. A regular x-ray is designed to produce a high quality picture and is a poor measure of density. ...Read more

Could chiropractic adjustments be unsafe if I have low bone density?

Possibly!: If your bone density becomes critically low, there is a risk that shearing, rotational or static force on your bones could result in a bone fracture. You must weigh the benefit of the treatment with the possible risk of bone trauma or fracture. ...Read more
