Avoiding foods that cause heartburn, eating smaller meals several times a day rather than three large meals, not bending after eating and quitting smoking may aid in treating hiatal hernia pain, according to Healthline. Avoiding going to bed right after a meal may aid in reducing the pain as well.
Caffeine, alcohol, chocolate, onions and spicy foods can trigger heartburn and lead to hiatal hernia symptoms, explains Healthline. Not lying down after eating and elevating the head by 6 inches may aid in reducing the risk of acid reflux, which is the most common cause of hiatal hernia. Avoiding wearing belts that are too tight and losing weight if overweight may help in preventing the problem.
