Pain after eating is one of the most common gut complaints there is, and one of the most frustrating, because food is the one thing you can't avoid. The good news is that your body usually leaves clues. Where the pain sits and how soon it starts after a meal can narrow things down a lot.

This guide isn't a diagnosis, but it will help you understand what's likely going on and have a much better conversation with your GP.

Clue 1: Where does it hurt?

• Upper middle, just below the breastbone. This is stomach territory. Burning or gnawing pain here points towards gastritis, an ulcer, or functional dyspepsia (indigestion without a visible cause).
• Behind the breastbone, rising into the chest or throat. Classic reflux. Acid or stomach contents travelling upwards.
• Under the right ribs. Often gallbladder related, especially if it follows fatty meals and spreads to the back or right shoulder. Worth getting checked.
• Lower abdomen. More likely the bowel, such as IBS, a food intolerance, or constipation.

Clue 2: When does it start?

• Within minutes to half an hour. The stomach itself is reacting. An irritated lining doesn't like being stretched or exposed to acid and spices, so gastritis and stomach ulcers often show up quickly.
• One to three hours later. Can still be the stomach, but also the gallbladder after a fatty meal, or a duodenal ulcer, which classically hurts when the stomach empties.
• Several hours later, with bloating and wind. Usually further down the gut, where food is being fermented. Common with IBS and with intolerances to lactose or certain carbohydrates.
• Mostly at night, lying down. Strongly suggests reflux. See our guide on why acid reflux is worse at night.

Clue 3: What else comes with it?

• Early fullness, nausea, upper bloating and belching often go with an inflamed stomach lining
• A sour or bitter taste, or a burning throat, points towards reflux
• Diarrhoea, constipation or cramping lower down points towards the bowel
• Hoarseness, throat clearing or a chronic cough can mean silent reflux

The most common culprits

Gastritis

Inflammation of the stomach lining. Pain tends to be burning, high up and quick to arrive after meals, especially rich, spicy, acidic or large ones. Painkillers, alcohol and H. pylori are frequent drivers.

Functional dyspepsia

Recurring indigestion where tests come back clear. It's real, common, and closely linked to stress and a sensitive gut nervous system.

Reflux

Burning that travels upwards, often worse when bending or lying flat. Our gastritis vs GERD guide explains how the two differ and overlap.

Food triggers and intolerances

Some foods irritate an already sensitive stomach (coffee, alcohol, chilli, citrus, tomato, fried food). Others cause trouble further down because they're poorly digested. A food and symptom diary for two weeks is the simplest way to separate the two.

What helps

• Shrink your portions. A stretched stomach hurts more. Five smaller meals beat three big ones.
• Slow down. Eating quickly means more swallowed air and less chewing, both of which add to discomfort.
• Stay upright after meals. Give it at least two to three hours before lying down.
• Cut back on common irritants for a few weeks, then reintroduce one at a time. Start with our list of foods that trigger gastritis.
• Check your painkillers. Regular ibuprofen or aspirin is one of the most overlooked causes of post meal stomach pain.
• Support the lining. If the pain is stomach based, ingredients like DGL liquorice, slippery elm, marshmallow root and aloe vera are traditionally used to soothe and protect the stomach lining.

When to see a doctor

See your GP if pain after eating is happening regularly for more than a few weeks, if it's getting worse, or if you're over 55 with new, persistent indigestion. Seek urgent help for severe pain that doesn't ease, vomiting blood, black stools, yellowing of the skin or eyes, difficulty swallowing, or unexplained weight loss.

Supporting a sensitive stomach

If your pain sits high up and arrives soon after meals, the stomach lining is the most likely place to focus. The Advanced Gut Repair Formula brings together 5g of L-glutamine, DGL, slippery elm, marshmallow root, aloe vera and Bacillus coagulans in one daily drink, built for people who want to support the lining itself rather than just react to symptoms.
