Understanding GERD and Gastritis: Symptoms, Diagnosis, and Treatment

If you’re experiencing heartburn, reflux, nausea, bloating, or upper abdominal pain — you may be dealing with GERD (gastroesophageal reflux disease) or gastritis.

These conditions are common, and can often be managed or reversed with a combination of targeted treatment and lifestyle changes.

How We Diagnose It

We start by reviewing your symptoms, medical history, medications, and dietary patterns. If needed, we may:

  • Order labs to check for anemia, inflammation, or H. pylori

  • Recommend an upper GI endoscopy (through a specialist)

  • Suggest a short trial of acid-reducing medication

  • Look at patterns over time to differentiate GERD vs. gastritis vs. functional dyspepsia

Symptoms to Watch For

It's important to pay attention to your symptoms and report them to your healthcare provider. Some common symptoms of GERD and gastritis include:

  • Burning in the chest or throat

  • Bitter taste in the mouth

  • Stomach pain or tenderness (especially upper abdomen)

  • Bloating, nausea, or early fullness

  • Worsening with lying down, stress, or certain foods

Common Medications That Can Worsen Symptoms

Certain medications can irritate the stomach lining or loosen the valve at the top of your stomach, making GERD and gastritis symptoms worse. These may include:

  • NSAIDs like ibuprofen (Advil), naproxen (Aleve), or aspirin

  • Steroids like prednisone

  • Iron supplements

  • Antibiotics like doxycycline or clindamycin

  • Bisphosphonates (for bone health) like alendronate (Fosamax)

  • Nitrates, calcium channel blockers, and certain sleep medications

  • Caffeine, alcohol, nicotine, and spicy foods may also aggravate symptoms

If you are taking any of these medications and experiencing symptoms, it's important to discuss with your healthcare provider to see if there are alternative options or adjustments that can be made.

Prevention and Lifestyle Changes

Making certain lifestyle changes can make a huge difference in managing GERD and gastritis symptoms. These may include:

  • Avoid food for 3+ hours before lying down or bedtime

  • Sit or stand upright for at least 30–60 minutes after eating or taking medications

  • Avoid overeating or eating too fast

  • Identify trigger foods (common ones: tomato, citrus, chocolate, caffeine, fried or spicy foods)

  • Elevate the head of your bed slightly if nighttime symptoms are severe

  • Reduce alcohol and tobacco use

  • Work on stress management, sleep quality, and meal timing

Treatment Options

If you are diagnosed with GERD or gastritis, your healthcare provider may recommend certain treatments to help manage your symptoms. These may include:

  • Short-term acid-reducing medications (like famotidine or omeprazole)

  • H. pylori testing and treatment (if gastritis is suspected)

  • Mucosal protectants like sucralfate

  • Reviewing and adjusting any meds that may be worsening your symptoms

  • A prevention-focused plan to support healing and long-term relief

If you’ve been self-managing with antacids or avoiding foods out of fear, it's important to seek guidance from your healthcare provider to get a clearer picture of what’s going on — and what your body actually needs.
