I have a hiaitus hernia, and the acid reflux is controlled with medication - proteum which I take morning and night.
I find my condition manageable - if i eat late before going to bed, i will get a surge of acid when i am asleep, and have to waken suddenly to vomit, so that is to be avoided. other than that, it is manbageable.
Surgery involvex taking the afected section of stomach above thw aesophagus, which cures the problem, but it removes the ability to burp, which can cause stomach pains.
I understand that current medical practice is to avoid surgery where possible, but your GP will obviously tell you more when he has assessed your individual condition.
