🔹 Introduction

Sodium Alginate is a naturally derived polysaccharide from brown seaweed. It is widely used in gastroenterology, especially for acid reflux (GERD), laryngopharyngeal reflux (LPR), gastritis, and post-meal acidity.
Today, alginate-based formulations are considered safer and faster-acting than many conventional antacids.

🔹 How Sodium Alginate Works in the Stomach

1️⃣ “Raft Formation” Technology

When sodium alginate reacts with gastric acid, it forms a floating gel-like raft on the top of stomach contents.
This raft prevents acid from moving upward into the oesophagus.

2️⃣ Reduces Reflux Episodes

It mechanically blocks acid reflux, unlike proton pump inhibitors (PPIs) which only reduce acid production.

3️⃣ Works Immediately

Relief begins within seconds to minutes, especially effective after meals.

🔷 Uses of Sodium Alginate in Gastroenterology

1. GERD (Gastro-Esophageal Reflux Disease)

This is the most common indication.
Alginate therapy is highly effective for:

  • Heartburn

  • Sour taste, regurgitation

  • Chest burning

  • Night-time reflux

  • Post-meal acidity

  • Acid splash or “water brash”

2. LPR (Laryngopharyngeal Reflux)

Symptoms:

  • Throat irritation

  • Cough

  • Voice changes

  • Recurrent sore throat
    Alginate reduces reflux reaching the throat and provides significant comfort.

3. Pregnancy-related Acidity

Safe for pregnant women because it has:

  • No systemic absorption

  • No effect on the fetus

  • No drug interactions

4. Hiatal Hernia Patients

Alginate is very helpful in those with anatomical reflux issues.

5. Post-Endoscopy or Post-Surgery Acidity

Used to soothe irritation after:

  • Endoscopy

  • Bariatric surgery

  • Anti-reflux procedures

  • Gastritis flare-ups

6. Gastritis & Acid-Related Indigestion

Provides a protective lining over the stomach wall.

🔷 Benefits Over Traditional Antacids

✔ Immediate relief

✔ No rebound acidity

✔ Safe in elderly and pregnant patients

✔ Can be used with PPIs and H2 blockers

सोडियम एल्जिनेट क्या है?

यह भूरे समुद्री शैवाल से बना एक प्राकृतिक पदार्थ है जो GERD, एसिडिटी, खट्टी डकार, LPR और गैस्ट्राइटिस में अत्यंत प्रभावी है।
