Its mainly dairy and some spicy foods, I ate a couple of boiled eggs yesterday and they upset me. I have lactose free milk in Tea and Coffee and cereal, but I dont drink much either. also sometimes with the hernia, food does not digest very quick
I used to have a hiatus hernia. It's all carb related. Spicy foods will do it no good, it's another food non starter, just as spuds and grains are for me. I don't do dairy also makes me vomit!
My hernia got better because I changed my lifestyle to low carb, losing weight and getting control of my blood sugars.
It is one step at a time. Firstly reduce your starchy and grain, rice, pasta, sugar intake and ease into smaller plate sizes, eat the non carby foods that you like, even if it's every day, just have a little less.
If you can just do a little more walking each day after eating, this helps with lowering your blood glucose levels. And any exercise even if it's chores is good.
Take it easy ,a little bit at a time, just keep reducing your carbs a little bit every day by Christmas you may be able to enjoy your Christmas dinner!
