Possible Causes
Generally, Bow legs can be related to:
- Osteoarthritis (OA)
Wear and tear of the joint cartilage over time. Risk factors include repetitive joint movements and carrying heavy loads for many years.
Osteomalacia / Rickets
Rickets is the softening and weakening of bones in children, usually due to an extreme and prolonged vitamin D deficiency. Vitamin D helps the body absorb calcium and phosphorus from food. Insufficient vitamin D makes it difficult to maintain proper calcium and phosphorus levels in bones, which can cause rickets.
- Rheumatoid Arthritis (RA)
A chronic inflammatory disease where the body's immune system attacks multiple joints, most commonly in the hands and feet. The cause and trigger is unknown.
- Osteoporosis
- Lumbar Spondylosis
Hypophosphatasia (HPP)

I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
