Acidity, GERD and ulcer diet: what to eat, what to avoid and when to see a doctor
For acidity and acid reflux (GERD), eat smaller meals, finish dinner 3 hours before lying down, raise the head of your bed, lose weight if you carry extra around the belly, and cut only the foods that clearly trigger you, often fried food, strong chai on an empty stomach and cold drinks. Pain with black stools, vomiting blood or trouble swallowing needs a doctor.
Acidity, GERD, gastritis and ulcer: what is the difference?
In Pakistan "acidity" or tezabiyat is used for almost any burning or discomfort in the chest or upper belly. Doctors separate it into a few conditions, and the diet is similar for all of them, but the danger signs and treatment differ.
| Condition | What happens | Typical feeling |
|---|---|---|
| Acid reflux / GERD | Stomach acid flows back up into the food pipe (oesophagus). Called GERD when it happens often or causes damage. | Burning behind the breastbone, sour liquid in the throat, worse lying down or bending |
| Gastritis | The stomach lining is inflamed, often from H. pylori, painkillers or alcohol. | Burning or ache in the upper belly, nausea, fullness |
| Dyspepsia (indigestion) | Upper-belly discomfort without one clear cause on tests. | Fullness after small meals, bloating, burping |
| Peptic ulcer | An open sore in the stomach or duodenum, mostly from H. pylori or painkillers. | Gnawing upper-belly pain, sometimes at night; can bleed |
7 rules of an acidity and GERD diet
- Eat smaller meals: a very full stomach pushes acid upward. Three moderate meals and one or two small snacks work better than one large dawat-style meal.
- Leave 3 hours between dinner and bed: this has some of the strongest evidence of any reflux habit. Also avoid lying down straight after lunch.
- Raise the head of the bed: put bricks or blocks under the head-end legs (about 15 to 20 cm) or use a wedge. Extra pillows bend the belly and help less. Sleeping on the left side can also reduce night reflux.
- Lose belly weight if you have it: even a few kilograms reduces reflux in people who are overweight. See the Pakistani weight loss diet.
- Cut your own triggers, not every food: common ones are fried and very oily food, strong chai or coffee (especially on an empty stomach), cold drinks, chocolate, mint, tomato-heavy salan, citrus, onion and very hot chilli. Keep a 2-week diary and remove only the ones that clearly bother you.
- Eat enough fibre and protein: daal, sabzi, chakki atta, oats and fruit keep the gut regular; constipation and straining can worsen reflux.
- Stop smoking and avoid tight waistbands: smoking weakens the valve at the top of the stomach; tight clothes squeeze the belly.
Foods that are usually gentle, and foods that often trigger acidity
| Usually gentle | Often a trigger (test for yourself) |
|---|---|
| Chapati, daliya, oats, boiled rice | Paratha, puri, naan with butter, bakery items |
| Moong and masoor daal, lauki, tori, tinda, kaddu, palak | Pakoray, samosay, chips, fried fish |
| Boiled or poached egg, grilled chicken or fish | Nihari, paye, karahi in lots of oil, fatty mutton |
| Plain dahi, raita, low-fat milk in small amounts | Full-cream milk late at night, malai, ice cream |
| Banana, papaya, seb, nashpati, kharbooza | Kinnu, malta, lemon in large amounts (for some people) |
| Water, saunf water, plain lassi | Strong chai, coffee, cold drinks, soda, energy drinks |
| Mild masala, zeera, dhania | Tez lal mirch, achaar, vinegar-heavy chutney |
These are patterns, not rules: many people with reflux eat tomato or chilli with no trouble. A diet that cuts too much becomes hard to keep and can leave you short of nutrients.
Sample one-day acidity and GERD diet chart
| On waking | 1 glass of water; take any acid medicine exactly as your doctor told you | no chai on an empty stomach |

Acidity medicines and diet: what the dietitian side is
Doctors use three main kinds of medicine: antacids and alginate syrups for quick relief, H2 blockers (such as famotidine) and proton pump inhibitors, PPIs (such as omeprazole and esomeprazole) to lower acid. People often search for these by brand name. Which one you need, the dose and how long to take it is your doctor's decision, because the right choice depends on the cause, and an ulcer or H. pylori needs its own treatment.
What diet adds:
- Medicine works better when the habits above are in place, and many people need less of it over time.
- Take it at the time your doctor or pharmacist says; some kinds only work well before a meal.
- If you take a PPI for many months, ask about checking vitamin B12 and magnesium, and include eggs, dahi, milk, fish and meat for B12. See vitamin B12 deficiency.
- Avoid painkillers such as ibuprofen, diclofenac and aspirin unless a doctor has prescribed them; they can cause gastritis and ulcers.
- If burning keeps coming back after treatment, ask about an H. pylori test. See the H. pylori diet page.
See a doctor first, or go now, if
- You have chest pain with sweating, breathlessness or pain spreading to the arm or jaw: it may be the heart, call 1122 now
- You vomit blood or something like coffee grounds, or pass black, tarry stools (go to hospital)
- Food sticks when you swallow, swallowing hurts, or you are losing weight without trying
- You are 60 or older with new indigestion, or you have anaemia or a family history of stomach cancer
- Severe or worsening belly pain, pain with fever, or repeated vomiting
- You are pregnant, have kidney or heart disease, or take blood thinners or daily painkillers
In these cases a general chart can be wrong for you. Book an online consultation.
Acidity and GERD diet: common questions
What are the symptoms of acid reflux?
The two classic symptoms are heartburn (a burning feeling behind the breastbone, often after meals or when lying down) and regurgitation (sour or bitter liquid coming up into the throat or mouth). Some people also get a sour taste, burping, nausea, a hoarse voice or a cough at night. Burning or pain in the upper belly, fullness after small meals and bloating are more typical of gastritis or dyspepsia.
What foods neutralize stomach acid immediately?
No food reliably neutralizes stomach acid. A few sips of water, sitting or standing upright and loosening a tight waistband help most. Milk may soothe for a short while, but its fat and protein can trigger more acid later, so it is not a treatment. Bland foods such as banana, oats and plain dahi are gentle, but they work by not irritating rather than by neutralizing. Home baking soda is high in salt and is not safe for people with high blood pressure, kidney or heart problems, or in pregnancy; ask a doctor or pharmacist instead.
How do I fix GERD for good?
GERD is often long-term, but most people control it well. The steps with the best evidence are losing weight if you are overweight, not eating for 2 to 3 hours before lying down, raising the head end of the bed, and stopping smoking. Avoid only the foods that clearly trigger you. Your doctor may add a medicine and will check for complications if symptoms are frequent or do not settle.
What is an ulcer, and what are stomach ulcer symptoms?
A peptic ulcer is an open sore in the lining of the stomach or the first part of the small intestine. The commonest causes are H. pylori infection and painkillers such as ibuprofen, diclofenac and aspirin. Typical symptoms are a burning or gnawing upper-belly pain, sometimes eased or worsened by food, with bloating or nausea. Vomiting blood or passing black stools means bleeding and is an emergency.
Is spicy food the cause of ulcers?
No. Spicy food and stress do not cause ulcers; H. pylori and painkillers do. Hot chilli can still worsen burning in some people, so reduce it if it bothers you, but there is no need to eat completely bland food for life.
Pait dard ka ilaj kya hai?
Pait dard (stomach pain) has many causes: acidity, gas, constipation, food poisoning, an ulcer, gallstones, kidney stones or appendicitis. Mild pain after a heavy meal often settles with a light diet, water and rest. Go to a doctor the same day if the pain is severe, keeps getting worse, sits on the lower right side, comes with fever or vomiting, or if you are pregnant. Do not take painkillers like ibuprofen or diclofenac for stomach pain without advice, because they can cause ulcers.
Is it safe to take acidity medicine for a long time?
Acid-reducing medicines are safe and effective when a doctor prescribes them, but long-term use should be reviewed so that you take the lowest amount that works. Long use has been linked to lower vitamin B12 and magnesium. Do not stop or change your medicine by yourself; ask your doctor whether it is still needed.
Is ulcerative colitis the same as a stomach ulcer?
No. Ulcerative colitis is a long-term inflammation of the large bowel that causes diarrhoea, often with blood, and belly cramps. It needs a gastroenterologist and a different diet plan. This page is about acidity, reflux, gastritis and stomach ulcers.
What should I eat at sehri and iftar if I have acidity?
At sehri, eat a normal-sized meal (chapati, egg or daal, dahi) and stop at least 30 minutes before lying down; skip paratha and very salty food. At iftar, open with dates and water, pray, then eat a moderate meal instead of a plate of pakoray and samosay. Keep chai and cold drinks small. If you take acid medicine, ask your doctor how to time it while fasting.
