Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. Hiatus hernia can cause acidity and farting. The reason being reflux and indigestion respectively. Your current treatment for the cause is right and appropriate. If you are still feeling the problem than you can add domperidone in the above regimen. It is a gastrokinetic and clears the bowel. This can help clear the fart from the bowel and also prevents gastirits. This treatment are only imperative and can only gives symptomatic relief. But the definitive treatment is only the surgery. Surgical correction of hiatus cs clear all your problems in once and for all. Till that time you can avoid spicy and more oily food. This are the reason for gastritis and indigestion. Walking a while after a diet can help you clear stomach and prevents the problem to you. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
