How to Treat Acid Reflux (GERD): Medications and Lifestyle Changes

Medically reviewed by Atul S. Vellappally, DNP, CRNP, FNP-BC — Family Nurse Practitioner

That burning sensation behind your breastbone after dinner, the sour taste creeping into the back of your throat, the feeling that something is stuck in your chest — if these experiences sound familiar, you are likely dealing with acid reflux. When it happens more than twice a week and starts affecting your quality of life, it crosses into the territory of gastroesophageal reflux disease, or GERD. An estimated 20 percent of the U.S. adult population experiences GERD symptoms regularly, making it one of the most common digestive conditions encountered in primary care.

The good news is that GERD is highly manageable. With the right combination of medications, dietary adjustments, and lifestyle modifications, most people achieve significant relief. This guide covers the full spectrum of treatment options so you can work with your provider to find what works best for you.

How Acid Reflux and GERD Work

Your lower esophageal sphincter (LES) is a ring of muscle at the junction where your esophagus meets your stomach. Under normal circumstances, this sphincter opens to let food pass into the stomach and then closes tightly to keep stomach contents in place. In people with GERD, the LES relaxes when it should not, or it does not close fully, allowing acidic stomach contents to flow back up into the esophagus.

The esophageal lining is not designed to handle the corrosive effects of stomach acid the way the stomach lining is. Repeated exposure can cause inflammation (esophagitis), erosion, and over time may contribute to complications such as strictures, Barrett's esophagus, or rarely esophageal cancer. This is why persistent reflux symptoms warrant proper evaluation and treatment rather than simply reaching for antacids indefinitely.

Medications for Acid Reflux and GERD

Proton Pump Inhibitors (PPIs)

PPIs are the most effective class of medications for treating GERD. They work by blocking the hydrogen-potassium ATPase enzyme system in the stomach's parietal cells, which dramatically reduces acid production. Common PPIs include omeprazole (Prilosec), esomeprazole (Nexium), lansoprazole (Prevacid), pantoprazole (Protonix), and rabeprazole (AcipHex). Some are available over the counter, while stronger doses require a prescription.

PPIs are most effective when taken 30 to 60 minutes before a meal, typically breakfast. This timing is important because PPIs block actively working acid pumps, and eating stimulates those pumps. Most patients notice improvement within a few days, though it may take up to two weeks to feel the full benefit. A standard initial course runs four to eight weeks, after which your provider will reassess whether you need ongoing therapy.

While PPIs are generally safe for short- to medium-term use, long-term daily use has been associated with potential concerns including changes in calcium and magnesium absorption, a slightly increased risk of certain infections such as Clostridioides difficile, and possible effects on vitamin B12 levels. These risks are relatively small for most people but underscore the importance of working with your provider to use the lowest effective dose for the shortest necessary duration.

H2 Receptor Blockers

H2 blockers reduce acid production by blocking histamine receptors on the stomach's acid-producing cells. Famotidine (Pepcid) is the most widely used H2 blocker available today, offered in both over-the-counter and prescription strengths. H2 blockers are less potent than PPIs but work faster, often providing relief within 30 to 60 minutes. They can be particularly useful for on-demand symptom control, nighttime symptoms, or as a step-down option after a PPI course.

Some patients find that H2 blockers lose effectiveness over time due to a phenomenon called tolerance, where the stomach adjusts to the reduced acid environment. This is one reason H2 blockers are sometimes used intermittently rather than daily for extended periods.

Antacids

Over-the-counter antacids such as calcium carbonate (Tums), magnesium hydroxide (Milk of Magnesia), and aluminum hydroxide neutralize stomach acid that has already been produced. They provide the fastest symptom relief, often within minutes, but the effect is temporary, lasting one to three hours. Antacids are best used for occasional breakthrough symptoms rather than as a primary treatment for GERD. Heavy reliance on antacids for persistent symptoms signals the need for a more comprehensive treatment approach.

Dietary Changes That Make a Difference

What you eat, how much you eat, and when you eat all influence GERD symptoms. While there is no single universal GERD diet, certain patterns consistently help reduce reflux episodes.

Common trigger foods include citrus fruits and juices, tomato-based sauces and soups, spicy foods, chocolate, coffee and caffeinated beverages, carbonated drinks, alcohol (especially red wine), fried and fatty foods, garlic, raw onions, and peppermint. These foods can relax the LES, increase acid production, or directly irritate the esophageal lining.

However, triggers are highly individual. A food that worsens one person's reflux may be perfectly fine for another. Keeping a food diary for two to three weeks can help you identify your personal triggers rather than unnecessarily restricting your diet. Note what you ate, when you ate it, and whether symptoms followed.

Meal size and timing matter as much as food choices. Eating smaller, more frequent meals rather than three large ones reduces the volume of stomach contents that can reflux. Avoid eating within two to three hours of lying down, as a recumbent position makes it easier for acid to travel from the stomach to the esophagus. If you tend to snack in the evening, try moving your last meal or snack to at least three hours before bedtime.

Eating pace also plays a role. Eating too quickly can cause you to swallow excess air, which increases gastric pressure and promotes reflux. Taking your time with meals, chewing thoroughly, and putting your fork down between bites are simple habits that can meaningfully reduce symptoms.

Sleep Position and Nighttime Reflux

Nighttime reflux is particularly troublesome because lying flat eliminates the gravitational advantage that helps keep stomach contents in place during the day. Nocturnal reflux also tends to cause more esophageal damage because the natural acid-clearing mechanisms — swallowing and saliva production — decrease significantly during sleep.

Elevate the head of your bed by six to eight inches. This does not mean simply adding extra pillows, which can bend your body at the waist and actually increase abdominal pressure. Instead, use a foam wedge pillow that elevates your entire upper body, or place bed risers under the legs at the head of your bed. This creates a gentle incline that uses gravity to keep acid in the stomach.

Sleep on your left side. Research consistently shows that left-side sleeping reduces reflux episodes compared to right-side or back sleeping. This relates to anatomy: when you lie on your left side, the stomach hangs below the esophageal junction, making it harder for acid to flow upward. The lower esophageal sphincter also sits above the level of stomach acid in this position.

Avoid late meals and alcohol before bed. Both increase the likelihood of nighttime reflux. If you need a bedtime snack, choose something small and non-acidic, and try to finish it at least two hours before lying down.

Other Lifestyle Modifications

Weight management is one of the most impactful lifestyle changes for GERD. Excess abdominal weight increases pressure on the stomach, which pushes contents toward the LES. Studies show that even modest weight loss of 5 to 10 percent of body weight can meaningfully improve GERD symptoms. This is often the single most effective long-term intervention.

Avoid tight clothing around the midsection. Tight belts, waistbands, and shapewear increase abdominal pressure, which promotes reflux. Opt for clothing with a comfortable, relaxed fit around the waist.

Quit smoking if applicable. Nicotine relaxes the lower esophageal sphincter, increases acid production, and impairs saliva production, all of which exacerbate GERD. Smoking cessation is recommended as part of comprehensive reflux management.

Manage stress. While stress does not directly cause acid production, it can heighten your perception of reflux symptoms and lead to behaviors that worsen reflux, such as overeating, eating quickly, or increasing alcohol consumption. Incorporating stress-management techniques such as regular physical activity, deep breathing exercises, or mindfulness can indirectly support GERD management.

When to Seek Further Evaluation

Most people with GERD respond well to a combination of medication and lifestyle changes. However, certain symptoms require prompt evaluation. Seek care if you experience difficulty swallowing or a sensation of food getting stuck, unintentional weight loss, persistent vomiting, vomiting blood or material that looks like coffee grounds, black tarry stools, chest pain (always rule out cardiac causes first), or symptoms that do not improve after four to eight weeks of appropriate treatment. These could indicate complications or an alternative diagnosis that needs attention.
