Osteoporosis Flashcards
Define Osteoporosis
Osteoporosis is a skeletal disease in which the bones become porous due to an excessive loss of proteins and minerals, especially calcium
When does osteoporosis develop
It develops when the breakdown of bone tissue occurs faster than the rebuilding does. Bone density and strength decreases. Bones break and become brittle. It usually happens in the hips, wrists and spine
What are the main symptoms of Osteoporosis
Back pain from cracked or broken vertebrae
Posture worsens as bones and vertebrae collapse on themselves
Bone fractures happen really easily
Are there symptoms in the early stages of Osteoporosis
No, there are no symptoms in the early stages. The disease is irreversible once you have it
Why are women at a higher risk for Osteoporosis
- Menopause decreases estrogen levels which prevents bone loss
- This also happens in pregnancy. The fetus will also take calcium from the moms bones if it needs
- Women have a lower bone mass
At what age do bones start to break down faster than we can build them
After age 30
What 3 micronutrients are especially important for bone health
- Vitamin D
- Calcium
- Phosphorus
What 3 external factors can cause Osteoporosis
- Certain medications
- Excessive alcohol
- Smoking
What are 3 general causes of Osteoporosis
- A hyper active thyroid
- Body form and family history
- Excessive weight loss
Other than Vitamin D, Calcium and Phosphorus, which nutrients are important for bone health
- Vitamin C
- Fluoride
- Zinc
- Manganese
- Magnesium
- Potassium
- Protein
What should you avoid in order to minismise your risk for Osteoporosis
- Protein rich diet
- Drinking alcohol
- Smoking
Why is Vitamin C necessary to prevent Osteoporosis
Vitamin C is needed to make natural collagen which is needed in bone marrow, it helps to build bone density
Why is a high protein diet a risk factor for Osteoporosis
When protein is digested it releases an acid into the bloodstream. Calcium from our bones is then called to counteract the acid levels. This causes bone demineralisation which furthers the breakdown of bone density
