What are the risk factors ...

• 1. Gender: women are more exposed than men to osteoporosis
• 2. Age: older people and especially women because of the loss of oestrogen protection which disappears after the menopause
• 3. Heredity
• 4. Smoking 
• 5. Excessive consumption of alcohol
• 6. Being underweight.
• 7. A lack of physical activity
• 8. Insufficient sunshine: it can cause a deficiency in vitamin D. Remember that the sun's ultraviolet rays enable the synthesis of vitamin D in the skin. Vitamin D promotes calcium absorption by the gastrointestinal tract.
• 9. Hormonal factors: the lack of oestrogen after the menopause
• 10. Taking certain medications: there are treatments that promote the occurrence of osteoporosis

The risk of developing osteoarthritis increases primarily based on factors that promote the wear of the joints:

• 1. Gender: Women especially after the menopause are more prone to osteoarthritis
• 2. Inappropriate physical exercise. Overworking the joints, in particular, by too intensive sports training or repetitive movements at work are likely to lead to osteoarthritis.
• 3. microtrauma : Microscopic lesions, due to too much stress, can cause trauma to the joints and are likely to lead to osteoarthritis.
• 4. Excess weight : This causes extra work for the joints
• 5. Congenital anomalies : Congenital dislocation of the hip
• 6. Genetic defects affecting the structure of cartilage : To learn more about the formation mechanisms of osteoarthritic lesions, take a look at the section on "Understanding."
