A corrosive injury happens when someone accidentally or deliberately swallows a harsh, caustic chemical. Think of strong toilet cleaners, bathroom acids, drain unblockers, caustic soda, industrial chemicals, or bleach. When swallowed, these substances instantly burn the delicate lining of your throat, food pipe (esophagus), and stomach.
How bad the burn (injury) gets depends on a few specific things:
Swallowing any caustic chemical is a critical medical emergency. You need immediate hospital care.
The chemical burns everything in its path on the way down. The esophagus and stomach take the heaviest hit.
However, the damage can spread to other areas too:
In India and many developing nations, caustic chemicals remain a persistent public health problem simply because they are cheap and easy to buy.
The most common culprits include:
A chemical burn is progressive and injury does not stop causing trouble once the emergency room visit is over.
Doctors rely on a few specific checks to see how far the burn went and decide on the best plan of attack.
The first goal is stabilizing you. Doctors protect your breathing, give IV fluids, control your pain, and watch closely for internal tears. When a throat is severely burned, eating normally is impossible. Yet your body needs fuel to heal. Doctors often place a temporary feeding tube through the nose or put a small tube directly into the small intestine (a feeding jejunostomy) to keep your nutrition steady.
This is the standard, first-choice treatment for opening up narrowed scar tissue. Instead of putting you through a major operation, a doctor passes a small balloon down your food pipe during an endoscopy. Inflating the balloon gently stretches the tight scar tissue open.
This approach protects your natural esophagus, makes swallowing easier, and keeps many patients out of surgery. However, scar tissue loves to shrink back down. Many people need repeated stretching sessions over weeks or months to keep the passage open.
Balloon stretching cannot solve every stricture. Surgery becomes necessary if:
If your food pipe is too badly scarred to ever work again, surgeons rebuild a brand-new path for food:
The recovery is a long process. You need regular check-ups. Your doctor ensures strictures do not quietly creep back, protect your nutrition, and tries to keep swallowing normal.
Dr. Goel brings specialized experience in treating corrosive esophageal and stomach burns, tight strictures, and stomach outlet blockages. His practice combines advanced endoscopic balloon dilatation with robotic esophageal and reconstructive surgery. Patients receive coordinated care from a team that brings together gastroenterology, clinical nutrition, endoscopy, and advanced GI surgery.
When harsh chemicals like acids or alkalis touch tissue, they cause instant chemical burns. As those deep burns heal over weeks and months, tough scar tissue forms, often squeezing the food pipe shut.
Strong toilet acids, drain unblockers, caustic soda, bleach, and industrial chemicals cause severe damage because they eat through delicate lining almost instantly.
Severe burning pain in the throat or chest, inability to swallow, nonstop drooling, vomiting blood, and trouble breathing are major warning signs that require emergency care.
Yes, 100% of the time. You must head to an emergency hospital right away. Life-threatening issues like internal tears or severe infections can develop within just a few hours.
Specialists use an upper GI endoscopy as their primary check to see the burns firsthand. They also use CT scans and contrast swallow X-rays to check for tears, measure narrowed spots, and examine the stomach.
It is a tight band of scar tissue that forms inside your food pipe after a chemical burn. It acts like a bottleneck, making it hard for solid food and liquids to pass down into your stomach.
Yes. Most patients start with endoscopic balloon dilatation, where a doctor gently stretches open the tight spot with a tiny balloon, skipping skin cuts entirely.
A specialist guides a deflated balloon through an endoscope directly into the narrow scar tissue and slowly inflates it to widen the opening so food can pass through again.
Surgery becomes necessary when the stricture is too long, the food pipe is completely blocked, balloon stretching stops working, or the stomach outlet is severely scarred.
When the original food pipe cannot be saved, surgeons rebuild your swallowing pathway using either your stomach or a piece of your colon.
Most patients see a major improvement in their swallowing after balloon dilatation or reconstructive surgery, though the final outcome depends on how deep the initial burn went.
Yes. Scar tissue can slowly tighten over time, causing delayed swallowing issues, vomiting, and weight loss, which is why regular follow-ups with a specialist are so important.
It depends on how bad the initial injury was. Mild burns heal faster, while severe burns with tight strictures may need repeated stretching sessions or major reconstructive surgery over several months.
See a specialist right away if you swallowed a chemical in the past and now struggle to swallow, feel food sticking in your chest, keep throwing up, or are dropping weight without trying.
