| Latest advice from DAN seems to read that SOME people can have a problem and should only not dive if the distension persists.
"A few who have had surgical repair of their hiatal hernia (e.g., fundoplication) can suffer from gas-bloat syndrome, which is associated with gaseous distension of the stomach. This is believed to occur due to one’s inability to expel swallowed air by belching. During an ascent, this distension can also lead to gastric rupture. The symptom usually resolves within a few weeks. If the distension persists, however, diving is not advised." |
