Acid Reflux vs. Gastritis: Differences, Symptoms & Treatment

Ever had that burning feeling in your chest or stomach that shows up uninvited? You're not alone — welcome to the world of digestive troubles. While acidity and gastritis often feel the same, there’s a key difference between acidity and gastritis. Think of them as troublesome cousins, similar, but not quite the same. Knowing the difference can help you treat them right and feel better. Let’s take a closer look at their symptoms and how to manage them.

Did You Know?

Acid reflux can occur after eating a heavy meal or if you lie down shortly after eating.

 

Gastritis vs. acid reflux: The ultimate showdown

Think of your stomach as a busy place where a lot is going on. On one side, there’s gastritis — this means your stomach lining is irritated or inflamed. It causes ongoing pain, often made worse by consuming items like spicy food, coffee, alcohol, or living a stressful life. It doesn’t always make a big scene, but it lingers and can feel uncomfortable for a long time.

Then there’s acid reflux, which happens when stomach acid travels back up into your food pipe (oesophagus). This can cause a burning feeling in your chest, called heartburn, and sometimes a sour taste in your mouth or even burping.

Even though they both cause discomfort in the stomach area, understanding the acidity and gastric differences is important. Gastritis is more about inflammation inside the stomach, while acid reflux is about acid going the wrong way. 

Acid reflux: The rebel with a cause

Acid reflux or its more serious form GERD (Gastro-oesophageal Reflux Disease) happens when stomach acid flows back up into the oesophagus. This can cause:

Heartburn: A burning feeling in the chest or throat

Regurgitation: When food or acid comes back up into your mouth

Difficulty swallowing: A sensation of food getting stuck or hard to swallow

As per a study, the primary symptom of GERD is heartburn, which is usually a burning sensation in the chest, accompanied by regurgitation of sour or bitter fluid to the mouth or throat.

Quick Explainer

You might not feel any symptoms of gastritis. If you do, it could signal it’s been there a while or has gotten worse.

 

Gastritis: The inflamed intruder

Gastritis is like that unwelcome guest that crashes your stomach lining, causing inflammation. This can be due to several reasons, including:

  • Helicobacter pylori infection: A virulent bacterium that's been associated with chronic gastritis.

  • Excessive usage of certain meds: Taking medications too often or in large amounts.

  • Alcohol consumption: Partying too hard with the booze can irritate the stomach lining.

Gastritis symptoms might include:

  • Nausea or vomiting: Your body is telling you, "I'm not okay with this."

  • A feeling of bloating in your top abdomen after a meal: As if you've reached your stomach's storage capacity.

How common are acid reflux and gastritis? The popularity contest

Both conditions are quite common. GERD affects about 20% of people, making it a frequent flyer in the world of digestive disorders. Gastritis, on the other hand, can sneak up due to lifestyle choices or infections, with its prevalence varying globally.

Symptom showdown: Spotting the differences

While both conditions can bring discomfort, their symptoms aren't quite the same.

  • Acid Reflux:

    • Burning chest pain (heartburn)

    • Regurgitation of food or sour liquid

    • Trouble swallowing

  • Recurrent throat clearing and feeling of something stuck in throat (globus sensation)

  • Water brash

  • Gastritis:

Distinguishing between these is the key to proper treatment.

The culprits behind acid reflux: Who's stirring the pot?

Several factors can trigger acid reflux:

  • Dietary choices: Spicy foods, chocolate, and caffeine can be like frenemies to your oesophagus.

  • Obesity: Excess weight can press against your stomach, prompting acid to take the elevator up.

  • Smoking: Weakening of the lower oesophageal sphincter, which becomes more of an open doorway than a gate.

Gastritis triggers: What's lighting the fire?

Gastritis can be sparked by:

  • H. pylori infection (a common bacterial culprit)

  • Regular use of anti-inflammatory meds

  • Excessive alcohol consumption

Spotting the difference: Gastritis vs acid reflux

They both bother your stomach, but in different ways:

  • Location of discomfort:
    • Acid Reflux: Chest area, often after meals

    • Gastritis: Upper abdomen, can be persistent

  • Response to food:

    • Acid Reflux: Symptoms may worsen when lying down or after eating.

    • Gastritis: Eating might temporarily relieve pain, but not always.

Treatment options: Calming the storm

Quick Tip

Avoiding spicy food, alcohol, and caffeine can help soothe gastritis symptoms.

 

Managing these conditions often involves lifestyle tweaks and medications:

  1. Acid Reflux:

    Lifestyle changes: Elevate the head of your bed, avoid late-night snacks ensure a gap of few hours between meals and sleep, and ditch tight clothing.

    Medications: Certain prescription medicines can help reduce acid production.
  2. Gastritis:

        Dietary modifications: Avoid irritants such as hot spices, alcohol, and caffeine

        Medications: Meds prescribed by a doctor that decrease the production of acid facilitate                    healing.

It is vital to consult a medical professional to suit treatment to your individual requirements.

Frequently Asked Questions

Q1: Can stress lead to acid reflux or gastritis?

While stress doesn't directly cause either of the two conditions, it may exacerbate symptoms associated with them.

Q2: Is there a special diet to help manage the conditions?

Yes, eating a bland diet with acidic and non-spicy food is effective in controlling symptoms. You can also add high-fibre foods and probiotics.

Q3: Can I take over-the-counter medications for treatment?

Although over-the-counter drugs may bring some relief in the short term, you should consult a healthcare provider for long-term treatment to prevent any side effects.

Q4: Are these conditions likely to lead to serious illness?

Without treatment, both can have complications such as ulceration, bleeding, and an increased risk of stomach or oesophageal cancer.

Q5: How can I tell if my symptoms are due to acid reflux or gastritis?

Observing your symptoms with respect to timing, location, and triggers can help provide an answer. However, an evaluation from a medical provider will provide the best answer.
