GERD is treated with a combination of lifestyle changes and medication, starting with an 8-week course of a proton pump inhibitor (PPI) taken once daily before a meal. For most people, this standard approach controls symptoms effectively. When it doesn’t, options range from adding a second type of acid-reducing medication to surgical procedures that physically reinforce the valve between your stomach and esophagus.
What’s Actually Happening in Your Body
The barrier between your stomach and esophagus relies on two structures working together: a ring of smooth muscle at the bottom of your esophagus (the lower esophageal sphincter) and the surrounding diaphragm muscle. When this barrier weakens or relaxes at the wrong times, stomach acid flows upward into your esophagus, causing that burning sensation.
Interestingly, the main culprit isn’t a permanently weak valve. Most reflux episodes happen when the sphincter relaxes on its own, independent of swallowing. These relaxations are a normal reflex triggered by stomach distension, especially after meals, and they exist to let you vent gas. In people with GERD, these relaxations happen more frequently or allow more acid to escape than normal. This is why eating large meals or eating right before lying down makes symptoms worse: both increase stomach pressure and trigger more of these inappropriate relaxations.
Lifestyle Changes That Actually Help
The American College of Gastroenterology recommends several lifestyle modifications as part of any GERD treatment plan, and some have stronger evidence than others.
Weight loss is the single most impactful change if you’re overweight. Excess abdominal weight increases pressure on the stomach and pushes acid upward. Even modest weight loss can meaningfully reduce symptoms.
Meal timing matters more than most people realize. Avoid eating within 2 to 3 hours of bedtime. When you lie down with a full stomach, gravity can no longer help keep acid where it belongs, and your stomach is still distended enough to trigger sphincter relaxations.
Elevating the head of your bed helps with nighttime symptoms. Clinical trials consistently use a height of about 20 centimeters (roughly 8 inches), achieved either with blocks under the bed legs or a wedge-shaped pillow. Stacking regular pillows doesn’t work as well because it bends you at the waist rather than tilting your entire upper body. The goal is a gentle slope, around 20 degrees, so gravity helps keep acid in your stomach overnight.
Dietary triggers vary from person to person, but the strongest evidence points to a few categories. High-fat meals reduce sphincter pressure and slow stomach emptying, giving acid more opportunity to reflux. Carbonated beverages, citrus products, and spicy or fried foods also show consistent associations with worsening symptoms. Coffee, chocolate, and alcohol are commonly blamed, but systematic reviews haven’t found a statistically significant link between these and GERD risk at a population level. That said, if you notice a specific food triggers your symptoms, avoiding it is reasonable regardless of what the averages show.
Smoking weakens the esophageal sphincter and should be avoided.
First-Line Medication: PPIs
Proton pump inhibitors are the most effective medications for GERD. They work by shutting down the acid-producing pumps in your stomach lining, reducing acid output dramatically. The standard first-line approach is an 8-week trial of a PPI taken once daily, 30 to 60 minutes before a meal. This timing is important: PPIs work by binding to acid pumps that are actively producing acid, and eating activates those pumps. Taking a PPI at bedtime or without eating afterward significantly reduces its effectiveness.
If once-daily dosing doesn’t control your symptoms, splitting the dose into twice a day (before breakfast and before dinner) can be more effective than simply doubling the single dose. A low dose taken twice daily produces a more sustained reduction in stomach acid than a higher single dose.
Common over-the-counter PPIs include omeprazole (Prilosec) and esomeprazole (Nexium). If your symptoms resolve during the 8-week trial, the goal is to step down to the lowest effective dose or stop entirely if possible.
When PPIs Aren’t Enough: H2 Blockers
H2 blockers (like famotidine, sold as Pepcid) reduce acid through a different mechanism. They’re less potent than PPIs overall but have a useful role. They start working within about 60 minutes, with peak levels reached in 1 to 3 hours, and their effect lasts 4 to 10 hours. This makes them well-suited for on-demand use when you anticipate symptoms, like before a large meal, or as an add-on to a PPI for nighttime breakthrough symptoms.
H2 blockers are sometimes used as a step-down option for people who have controlled their GERD with a PPI and want to try a less potent medication for maintenance.
Long-Term PPI Risks in Perspective
You’ve probably seen headlines about PPIs causing kidney disease, bone fractures, or vitamin deficiencies. The risks are real but smaller than they sound, and they need to be weighed against the consequences of untreated GERD.
Large cohort studies have found that PPI use is associated with a roughly 28 to 45 percent increased relative risk of chronic kidney disease. That sounds alarming, but the absolute risk remains low for most people. One study of over 193,000 patients found a hazard ratio of 1.28 for chronic kidney disease, and the association with worsening kidney outcomes appeared to level off after about two years of use.
Bone fracture risk is thought to stem from reduced calcium absorption in a less acidic stomach. The FDA added and then partially retracted a bone fracture warning for PPIs because the evidence was inconsistent for short-term, low-dose use. For people on long-term, high-dose PPIs, maintaining adequate calcium and vitamin D intake is a sensible precaution.
Vitamin B12 depends on stomach acid for absorption, and short-term studies have shown PPIs can reduce B12 uptake. However, most people have enough B12 reserves that this doesn’t become clinically meaningful, and the effect hasn’t been consistently replicated in long-term studies. Routine B12 testing isn’t considered necessary solely because you take a PPI.
The practical takeaway: use the lowest PPI dose that controls your symptoms, and periodically reassess with your provider whether you still need it.
Surgical Options for Persistent GERD
When medications and lifestyle changes don’t provide adequate relief, or when you want to stop taking daily medication permanently, surgery becomes an option. The two main approaches both aim to physically strengthen the barrier between your stomach and esophagus.
Fundoplication is the traditional surgical approach. The surgeon wraps the top of your stomach around the lower esophagus to create a tighter valve. It’s done laparoscopically (through small incisions) and has decades of outcome data. About 81% of patients are able to stop PPIs afterward. The trade-off is that some people develop difficulty belching (only about 66% retain the ability) or experience gas and bloating. Roughly half of patients lose the ability to vomit, which is worth knowing before surgery.
Magnetic sphincter augmentation (the LINX device) is a newer alternative. A small ring of magnetic beads is placed around the lower esophageal sphincter, adding just enough force to keep it closed against reflux while still allowing food to pass through. The PPI elimination rate is similar to fundoplication (about 81%), but patients are significantly more likely to retain the ability to belch (95%) and vomit (94%) afterward. Long-term data beyond a few years is still limited compared to fundoplication.
Endoscopic Procedures
Transoral incisionless fundoplication (TIF) is a less invasive option performed through the mouth with an endoscope, leaving no external incisions. Five-year data shows about 77% of patients achieve a meaningful improvement in symptom scores, and roughly 85% reduce or eliminate PPI use. However, TIF has specific eligibility requirements: it works best for people with small or no hiatal hernias (under 2 cm), no Barrett’s esophagus, and a BMI under 35. It’s not appropriate for people with severe esophageal inflammation or prior upper GI surgery.
What Happens Without Treatment
Untreated GERD doesn’t just cause discomfort. Chronic acid exposure can inflame and damage the esophageal lining, leading to erosive esophagitis, strictures (narrowing from scar tissue that makes swallowing difficult), or Barrett’s esophagus, a condition where the esophageal lining changes to resemble intestinal tissue. Barrett’s esophagus is a precursor to esophageal adenocarcinoma, a serious cancer, though the progression rate is low.
If your symptoms don’t improve after an 8-week PPI trial, or if they return when you stop the medication, the ACG recommends an endoscopy, ideally after stopping PPIs for 2 to 4 weeks so any mucosal damage is visible. Difficulty swallowing, unintentional weight loss, or signs of GI bleeding warrant an endoscopy as a first step rather than a trial of medication.
