Cartilage is a cushion-like layer that helps prevent bones from rubbing against each other in the joints. When it wears down, the bones rub against each other and cause severe pain. The main reasons for this are as follows:
1. Ageing
The most common cause of osteoarthritis is aging. As we age, the cartilage in the joints naturally wears down and its ability to regenerate decreases.
2. Obesity
When we gain weight, our joints, especially the knees and hips, experience excessive pressure. This causes the cartilage to wear down faster. Every extra kilo of weight puts a lot of strain on the knees.
3. Joint Injuries
Old sports injuries, accidents, or surgeries can affect the natural structure of the joints. People with such injuries are more likely to develop osteoarthritis years later.
4. Genetics
Some people are genetically predisposed to joint deformities or cartilage loss. If someone in your family has osteoarthritis, you are more likely to develop it.
5. Strenuous physical activity
Those who stand for long periods of time, lift heavy objects regularly, or perform repetitive tasks that put pressure on the same joint are also more likely to develop osteoarthritis.
6. Hormonal changes and gender
Women are more likely to develop osteoarthritis than men. The decline in estrogen levels, especially after menopause, can affect bone and joint health.
