My wife suffers with acid reflux. Unfortunately, she hasn't had much luck controlling it. She takes over the counter Omeprezole every day, which seems to help but doesn't eliminate it.
Changing eating or drinking habits can help a little, but it's generally not sustainable for her.
Honestly, most of her acid reflux seems to be caused by stress. When she has time off work or can just relax for a few days, she doesn't seem to be bothered with acid reflux even if she doesn't take the medicine.
This is getting to be a pretty long post, but I didn't take time to read them all. But let me give my take on this subject since I just returned from the hospital after my wife was in for 5 days.
My wife has had acid reflux for maybe 15 years. On 4 occasions, she was in the hospital for aspirational reflux in her sleep--causing pneumonia. Her doctor at the time preached against getting a huge hiatal hernia fixed. But the reflux was eroding her esophagus. She continues to sleep elevated in an adjustable bed, and doesn't overload her stomach.
My wife finally had the surgery 2 years ago, and she's done very well. About 3 weeks ago, she awoke with a bad taste in her mouth. But she didn't spike any high temperature like she always did with pneumonia.
Last Wednesday night, she suddenly fainted and fell. She was running a low grade fever. We put the blood pressure cuff on her, and she was 53 points over death. Hauled her to the emergency room, and they had the crash team in the room. All the while, she was talking and thinking clearly.
Chest X Rays showed nothing. But she was in complete Afib--fluttering heart. And a Cat Scan showed what could have been either pneumonia or cancer. Thankfully it was pneumonia.
Next day, they shocked her heart back into rhythm, and her blood pressure's been fine. She just got home on oxygen a few minutes ago, and she'll be on blood thinners the rest of her life. But she was one breath from death.
Moral of the Story: Don't fool around with reflux, especially if you have a hiatal hernia. Get it fixed. Wait too long, and expect to have cancerous tissue and you're a goner. There's no more frightful thing than waking up in your sleep to have stomach acid going down your wind pipe. Find a good doctor to guide you.
