This increases the chances of developing gout

The correct option is genetics – family history.

Gout is a painful form of arthritis that occurs when high levels of uric acid build up in the blood, causing crystals to form and accumulate in and around a joint. The development of gout is strongly influenced by both genetic and environmental factors. Among the options provided, having a family history of gout (genetics) is a well-established and significant risk factor that directly increases a person's susceptibility to the condition.

Let us look at why the other options are not the primary correct answer:
1. Diet having high salt content: While diet plays a crucial role in gout, it is specifically diets rich in purines (such as red meat, organ meats, seafood, alcohol, and sugary beverages containing fructose) that elevate uric acid levels, rather than general salt intake.
2. Asthma: Asthma is a chronic respiratory condition affecting the airways and is not a direct risk factor or cause for the development of gout.

Therefore, a genetic predisposition or family history of the condition is the option that directly increases the chances of developing gout.
