Indigestion vs. Gastric Ulcer: How to Recognise the Difference
We have all been there. You enjoy a rich, spicy dinner at a wedding or indulge in one too many deep-fried snacks during a festival. An hour later, you feel that familiar burning sensation in your chest or a heaviness in your stomach. You reach for an antacid, assuming it is just a bit of gas or acidity.
But what if that burning sensation doesn’t go away? What if it keeps coming back, week after week?
Stomach pain is tricky. It is often hard to tell if you are suffering from a temporary bout of indigestion or something more serious, like a gastric ulcer. Because the symptoms overlap significantly, many people ignore ulcers for months, thinking they have a “sensitive stomach.”
At Eskag Sanjeevani Hospitals, we believe that understanding your body is the first step to healing. In this blog, we will break down the link between ulcer and indigestion, help you spot the warning signs, and explain when it is time to stop the home remedies and see a specialist.
Takeaways
- While indigestion is usually a temporary discomfort caused by food or lifestyle, a gastric ulcer is an open sore on the stomach lining that requires medical treatment.
- The timing of the pain is a major clue: indigestion often happens immediately during or after a meal, whereas ulcer pain can be inconsistent and may worsen on an empty stomach or at night.
- If you experience unexplained weight loss, black stools, or vomiting, you must visit a gastroenterologist at Eskag Sanjeevani Hospitals immediately, as these are signs of a bleeding ulcer.

What is Indigestion? (The “Everyday” Problem)
To understand the difference, we first need to clarify the meaning. Medically known as dyspepsia, indigestion is not actually a disease itself. Instead, it is a collection of symptoms that happen when your body struggles to break down food.
It is usually a sign that your stomach acid is irritating the protective lining of your digestive system (the mucosa) or that your stomach is stretching too much after a large meal.
Common Causes of Indigestion:
- Eating too fast: Swallowing air along with your food causes bloating.
- Trigger foods: Spicy curries, fatty foods, chocolate, and caffeine are notorious culprits.
- Lifestyle: Smoking, alcohol, and high stress levels increase acid production.
- Medications: Some painkillers (like ibuprofen) can irritate the stomach lining.
- The Feeling: Indigestion usually feels like an uncomfortable fullness. You might feel “stuffed” even if you haven’t eaten much. There is often a burning sensation in the upper abdomen (heartburn) and occasionally nausea.The key thing to remember is that simple indigestion usually resolves itself within a few hours or after taking an over-the-counter antacid.
What is a Gastric Ulcer? (The “Serious” Condition)
A gastric ulcer (also called a stomach ulcer) is different. It is not just irritation; it is actual damage.
Imagine a small, open sore or a raw patch on the inside of your stomach lining. That is an ulcer. Your stomach contains strong acids to digest food. To protect itself, the stomach is coated with a thick layer of mucus. If that mucus layer breaks down, the acid eats away at the stomach lining, creating a painful sore.
What Causes Ulcers?
Unlike common belief, stress and spicy food do not directly cause ulcers (though they make them worse). The two main causes are:
- H. pylori Bacteria: A common bacterial infection that damages the stomach lining.
- NSAIDs: Long-term use of non-steroidal anti-inflammatory drugs (like aspirin or ibuprofen) for pain relief.
Gastric Ulcer Symptoms to Watch For:
- A gnawing or burning pain in the middle of your stomach.
- Pain that may disappear for a few days and then return.
- Anaemia (feeling tired and pale).
- Dark, tarry stools (a sign of internal bleeding).
Ulcer and Indigestion: The Showdown (How to Tell Them Apart)
Since both conditions involve burning stomach pain, how do you know which one you have? While a proper diagnosis requires a doctor, here are a few clues that can help you differentiate between an ulcer and indigestion.
1. The Timing of the Pain
- Indigestion: The pain usually hits during or immediately after a meal. It is a direct reaction to what you just ate.
- Ulcer: The pain pattern is more complex.
- Gastric Ulcers: often hurt shortly after eating because the food stimulates acid production, which hits the sore spot.
- Duodenal Ulcers: (ulcers in the upper intestine) often hurt 2 to 3 hours after eating or in the middle of the night when the stomach is empty. Eating sometimes relieves this pain temporarily.
2. The Type of Pain
- Indigestion: Feels like heat, burning, or an inflated balloon in your upper belly. It often travels up towards the chest (heartburn).
- Ulcer: Often described as a “gnawing,” “dull,” or “aching” pain. It feels like something is eating away at your stomach. The pain is usually localised to a specific spot rather than a general burning sensation.
3. Response to Antacids
- Indigestion: Taking a standard antacid usually brings quick, significant relief.
- Ulcer: Antacids might provide brief relief (by neutralising the acid for a moment), but the pain usually returns quickly because the sore is still there.
4. Other Physical Signs
- Indigestion: lots of burping and gas.
- Ulcer: You might lose your appetite completely. Unexplained weight loss is a classic sign of an ulcer, whereas indigestion rarely affects your weight.
Treating the Problem: What Are Your Options?
The approach to healing depends entirely on the diagnosis.
Indigestion Treatment
If your issue is simple dyspepsia, you can usually manage it at home:
- Eat smaller meals: Do not overload your stomach.
- Slow down: Chew your food thoroughly.
- Don’t lie down after eating: Wait at least 3 hours before going to bed.
- Identify triggers: If spicy food hurts, cut it out for a while.
Ulcer Treatment
You cannot treat an ulcer solely with lifestyle changes. It is a wound that needs medical intervention including:
- Antibiotics: The ulcer can be caused by H. pylori bacteria; your doctor will prescribe a course of antibiotics to clear the infection.
- Proton Pump Inhibitors (PPIs): These are medicines that reduce the amount of acid your stomach produces, giving the ulcer time to heal naturally.
- Stopping NSAIDs: If painkillers are the cause, your doctor will switch you to a stomach-friendly alternative.
When to Visit a Top Gastroenterologist at Eskag Sanjeevani Hospitals?
Stomach pain should not be a daily part of your life. If you have been popping antacids like sweets for more than two weeks, you need to see a specialist.
Seek immediate help if:
- You are vomiting blood or material that looks like coffee grounds.
- Your stools are black, sticky, or bloody.
- You have sudden, sharp, severe abdominal pain that doesn’t go away.
- You are losing weight without trying.

Generally, no. Indigestion itself does not cause ulcers. However, the causes of indigestion (like smoking, alcohol, or frequent painkiller use) are the same factors that increase your risk of developing an ulcer. If your indigestion persists, it may be an undiagnosed ulcer.
This is a common myth. Years ago, doctors recommended milk to coat the stomach. Today, we know that while milk soothes the pain for a few minutes, it actually stimulates the stomach to produce more acid and digestive enzymes, which can make the ulcer pain worse in the long run.
The most accurate method is upper gastrointestinal endoscopy (gastroscopy). A doctor at Eskag Sanjeevani Hospitals will pass a thin camera down your stomach to look for sores. They may also use breath or stool tests to detect H. pylori.
Ginger tea, peppermint tea (unless you have reflux), and baking soda mixed with water can help neutralise acid. However, the best treatment is prevention: eat slowly, avoid late-night snacking, and manage stress.
With the correct medication (usually PPIs and antibiotics), most ulcers heal within 4 to 8 weeks. However, you must finish the full course of medication even if the pain stops; otherwise, the ulcer may return.
No, spicy food does not cause ulcers—bacteria and painkillers do. However, if you already have a cut (ulcer) in your stomach, spicy food is like pouring chilli powder on a wound. It will cause extreme pain and irritation.
Eskag Sanjeevani Hospitals is widely considered one of the best centres for gastroenterology in Kolkata. With multiple branches (including Baghbazar and Khardah), we offer expert care for acidity, ulcers, and liver diseases.
