Do I have acid relfex?

You are essentially correct, except that it's called 'acid reflux', not 'acid reflex'.

Acid reflux is often associated with what is known as hiatus hernia where a portion of your intestines protrudes upwards through your diaphragm although injury during surgery can cause a 'weak spot' which might give the same effect. What it means is that the sphincter muscle that keeps your stomach contents from traveling back up your oesophagus cannot close properly. You might find that when you bend over you get that 'acid sick feeling' - a sure sign that your sphincter isn't fully closed.

Losing weight will help as it will put less pressure on the gastric sphincter and/or hiatus hernia if you have one. You're right that certain foods can cause the problem more than others - it's often acid foods... tomatoes are particularly bad for many. Try to eat little and often rather than big meals. Avoid the foods that upset you. When sitting, try to sit up straight and exercise by walking, keeping your back straight.

There are tablets which may help - one that's available over the counter is called Zantac while others are more powerful and available on prescription.

I would suggest seeing a doctor as soon as you can... I'm afraid that the dignosis involves a rather unpleasant procedure whereby a camera is passed down your gullet into your stomach. But the consequences of untreated chronic acid reflux are very nasty... it can lead to what is known as "Barretts Oesophagus" - a form of cancer with a very low survival rate.

Source - personal experience... I received a hiatus hernia at age 12 when someone whacked me in the guts with a baseball bat while my ex-wife developed one due to obesity. I cured mine gradually over many years of bitter experience, my ex-wife had to lose a lot of weight and is still taking prescription medicines.

I think Frank is essentially correct, but with one caveat: the surgery you had may indeed play a role in your reflux problems. See below.

From your description you may have had a cholecystectomy (removal of your gall bladder); really hard to tell from your description ( a little vague), but if so, that could explain things backing up on you IF you aren't careful with your meal sizes and how much fat you eat. Bile is necessary for efficient digestion of fat, and if your gallbladder is gone, then the bile gets into your gut little by little directly from the liver (normally in between meals, the liver, which makes the bile, pumps it into the gallbladder, which is a bile storage unit. When you eat a fatty meal, the gallbladder squirts all that bile into the gut). That huge slug of bile then helps in fat digestion. If you're missing your gallbladder and are in the habit of eating huge fatty meals, it will take longer to digest them, they'll sit in your stomach longer, and you'll be more prone to reflux. So, watch your fat intake and watch how much you eat at a given time--smaller, more frequent meals, that are lower in fat may help.

You do NOT want to delay getting seen by a physician. GERD is not uncommon in obese patients, and it's not something to mess with. 1) Over time, the lining of your esophagus can erode away, and 2) the injury to your esophageal epithelium by GERD is associated with cellular changes that can lead to esophageal cancer.

You have acid reflux. Your doctor can treat it.

I can't imagine a single pathway by which this could be caused by your surgery. This is coincidence.

But it doesn't matter. Your doctor can treat it either way.

You're doctor will not think that this is from bulimia.
