According to Everyday Health, the risk of arthritis can be reduced by controlling blood-sugar levels and staying hydrated. Healthline states that arthritis can be prevented by eating omega-3 acids, exercising and avoiding injury. However, arthritis is not always preventable. Causes such as increasing age, family history and gender are unavoidable.
Omega-3 fatty acids reduce inflammation in the body and help prevent arthritis, claims Healthline. A study in "Annals of the Rheumatic Diseases" found that women who eat fish regularly may be at a lower risk for rheumatoid arthritis, and the USDA recommends eating fish high in omega-3 fatty acids, such as salmon, trout, mackerel and sardines, twice a week. Exercise takes the stress of excess weight off the joints, and it strengthens the muscles around the joints. Injuring a joint can damage the cartilage and cause it to wear out more quickly.
According to the Arthritis Foundation, an injured joint is nearly seven times more likely to develop arthritis than one that was never injured. Fractures, dislocations, ligament tears and strains can significantly increase the risk of arthritis. Diabetes, which affects the body's ability to regulate blood sugar, may be a significant risk factor for arthritis. Diabetes can also trigger systemic inflammation that leads to cartilage loss. Everyday Health says that staying hydrated can also prevent arthritis. The cartilage found in joints is made up mostly of water, which acts as a cushion. Dehydration causes cartilage to be more easily damaged by wear and tear.
