I have had a few episodes extra gas and bloating feeling after I eat since my TIF Hiatus hernia repair. To solve this, I have been eating smaller amts. More frequently of food. Then after eating walking in my house around a path for 10 to 15 minutes. If I feel burning I take a table spoon of honey from my honey bear. Twice a day I drink 2 oz of Aloe Vera Juice. Aloe Vera Juice has helped me the best in all so I am improving. Couple table spoons of plain yogert a day will help too. Best wishes to your husband I hope he feels better soon. PS He can also place an ice pack to areas where he is feeling pain. That may help too.
