Hello and hope you are doing well.
Hernia is the protrusion of abdominal contents through an abnormal opening. So, any state of increased pressure like coughing, fluid in abdomen or gas can cause the hernia to be pushed out. So, the gas may have pushed the bowels through the opening, but is unlikely to cause a hernia. Since it is still reducible, it is unlikely to be complicated. Hernia needs to be repaired to prevent complications like strangulation. For this, a General Surgeon will be able to help you.
Hope this helped and do keep us posted.
