Why is my acid reflux worsening despite treatment?

Question

Hello doctor,

My acid reflux has been worsening again. Even small meals cause a burning sensation in my chest, especially when I lie down. I am taking the PPIs that were prescribed, but I feel like they are no longer effective. I have tried avoiding coffee and spicy food and sleeping with my head elevated, but I still wake up at night with a sour taste in my mouth. It is very uncomfortable.

Do people develop resistance to these medications?
I have also gained some weight recently.
Could that be making the symptoms worse?

I read online about a surgical option called fundoplication. Is that something that should be considered? There is concern about depending on medications long-term, but the reflux is significantly affecting sleep.

Kindly advise.

Hello,

Welcome to icliniq.com.

I understand the concern.

The described symptoms are typical of gastroesophageal reflux disease (GERD). Nighttime burning sensation and a sour taste in the mouth indicate that stomach acid is reaching the esophagus, especially when lying flat.

People do not develop true resistance to proton pump inhibitors (PPIs). However, symptoms may persist for several reasons:

The dose may not be optimal.
The timing of the medication may be incorrect.
The reflux may be more severe.
Recent weight gain may be increasing abdominal pressure.

Proton pump inhibitors such as Omeprazole, Pantoprazole, or Esomeprazole work best when taken 30 to 40 minutes before breakfast. In some cases, the dose may be temporarily increased to twice daily under medical supervision if symptoms continue.

Even a modest weight gain can worsen reflux symptoms. Increased abdominal pressure can push stomach acid upward into the esophagus. A reduction of approximately five to seven percent of body weight has been shown to significantly improve symptoms in many individuals.

Additional lifestyle measures that may help include:

Avoid eating within three hours before bedtime.
Consume smaller, more frequent meals.
Avoid tight-fitting clothing.
Reduce late-night snacks.
Limit alcohol intake.

If symptoms persist despite correct use of proton pump inhibitors, a physician may:

Adjust the dosage.
Add a bedtime histamine-2 receptor blocker (H2 blocker) such as Famotidine.
Recommend repeat upper gastrointestinal endoscopy.
Perform ambulatory pH monitoring to measure acid exposure.

Regarding surgery, Nissen fundoplication is a surgical procedure considered in selected patients with confirmed severe gastroesophageal reflux disease who do not respond adequately to optimized medical therapy. The procedure strengthens the lower esophageal sphincter to prevent acid reflux. However, surgery is generally considered only after appropriate diagnostic testing confirms persistent acid reflux despite proper treatment.

Most patients experience significant improvement with correct medication timing, dose adjustment, weight management, and lifestyle modifications. Long-term dependence on medication is not inevitable in all cases, and symptoms often improve once reflux is adequately controlled. Sleep quality typically improves when nighttime acid exposure is reduced.
