Acid Reflux and GERD: A Practical Diet and Exercise Guide

Almost everyone gets heartburn occasionally. When it becomes frequent, it has a name, gastro-oesophageal reflux disease, or GERD, and a different set of consequences. Left unmanaged over years, chronic reflux can inflame and damage the oesophagus, and it is one of the most common reasons people take daily medication indefinitely without ever addressing what is driving it.

The good news is that GERD responds unusually well to specific, unglamorous changes: what you eat, how much you eat at once, when you eat relative to lying down, how you exercise, and what you weigh. This guide covers all of them.

Important: This is general education, not medical advice. Persistent reflux needs medical evaluation, and some symptoms need urgent attention. Do not stop prescribed medication based on an article.

What Is Actually Happening

Between the oesophagus and the stomach sits a muscular ring, the lower oesophageal sphincter. Its job is to open when food arrives and stay closed the rest of the time. In reflux, it opens or leaks when it should not, allowing stomach contents, including acid, back up into the oesophagus, which has no protective lining for it.

Anything that either relaxes that sphincter or raises pressure inside the abdomen makes reflux more likely. That single idea explains almost every recommendation below.

Symptoms Beyond Heartburn

• Burning behind the breastbone, often worse after meals or lying down.
• Regurgitation, a sour or bitter taste rising into the throat.
• A persistent lump-in-the-throat sensation.
• Chronic dry cough, particularly at night.
• Hoarseness or a morning sore throat.
• Difficulty or discomfort when swallowing.
• Worsening asthma symptoms.
• Dental erosion, sometimes spotted by a dentist first.
• Nausea and excessive burping.
• Disrupted sleep from night-time symptoms.

An important caution: chest pain should never be assumed to be reflux. Cardiac pain can feel like burning or pressure, especially in women and people with diabetes. Chest discomfort that appears with exertion, or comes with breathlessness, sweating, or pain in the jaw, neck, or arm, needs emergency assessment.

The Trigger Foods, And Why

Triggers are individual, but these are the usual suspects, and each has a mechanism.

Foods that relax the sphincter

• Fatty and deep-fried food: Also slows stomach emptying, which prolongs exposure. The single biggest dietary factor for many people.
• Chocolate: Contains compounds that relax the sphincter.
• Peppermint: Counter-intuitively, mint often worsens reflux.
• Caffeine: Coffee and strong tea, both through caffeine and acidity.
• Alcohol: Relaxes the sphincter and irritates the lining.

Foods that irritate directly

• Tomato-based dishes, a real problem in Indian cooking, where tomato gravy is a base.
• Citrus fruits and juices.
• Very spicy food, though this is more variable than folklore suggests.
• Raw onion and garlic in quantity.
• Carbonated drinks, which raise stomach pressure directly.

Generally better tolerated

• Bananas, melons, apples, and pears.
• Oats, rice, roti, and other plain starches.
• Green vegetables, gourds, and pumpkin.
• Lean protein: grilled or steamed chicken, fish, egg whites, tofu, and moderate dal.
• Ginger in modest amounts.
• Low-fat curd, if dairy suits you.

Rather than eliminating everything at once, keep a simple two-week log of what you ate and when symptoms appeared. Most people find two or three genuine triggers, not twenty.

Habits That Matter More Than Food Lists

If you change nothing else, change these four.

1. Stop eating three hours before lying down. This is the highest-yield change for night-time reflux, and it is free. Late dinners are the single most common cause of the symptoms people blame on spice.
2. Eat smaller meals, more often. A full stomach raises pressure and stretches the sphincter. Four modest meals beat two large ones.
3. Elevate the head of your bed by 15 to 20 centimetres, using blocks under the legs or a wedge under the mattress. Extra pillows bend the neck and do not work as well.
4. Sleep on your left side. Anatomy means left-side sleeping reduces acid exposure compared to the right.

Also worth doing:

• Lose excess weight, particularly around the abdomen. Abdominal fat raises intra-abdominal pressure directly, and weight loss is one of the most effective GERD interventions available.
• Loosen tight waistbands and belts. Genuinely relevant, and often overlooked.
• Stop smoking. Tobacco weakens the sphincter and reduces saliva, which normally helps neutralise acid.
• Chew thoroughly and eat slowly. Less air swallowed, better digestion.
• Do not lie down immediately after eating, even for a nap.
• Manage stress, which alters both symptom perception and eating patterns.

Exercise: What Helps And What Hurts

Exercise is genuinely beneficial for GERD, mostly through weight management and improved gut motility. But certain movements provoke it, so the selection matters.

Usually well tolerated

• Walking, including a gentle walk after meals, which aids emptying.
• Cycling, particularly upright rather than aggressively hunched.
• Elliptical and stationary bike work.
• Moderate strength training, done upright with controlled breathing.
• Gentle yoga, avoiding deep inversions and hard compressions.

Often provoke symptoms

• High-impact running and jumping, especially soon after eating.
• Crunches, sit-ups, and heavy abdominal compression.
• Inversions: headstands, shoulder stands, downward dog held long, and decline bench work.
• Very heavy lifting with breath-holding, which spikes abdominal pressure.
• Swimming immediately after a meal, because of the horizontal position.

Practical rules

• Wait two to three hours after a meal before training.
• Sip water rather than drinking large volumes mid-session.
• Avoid tight compression garments around the waist.
• Swap crunches for planks, dead bugs, and bird dogs, which build core strength without the same compression.
• Breathe out on effort instead of holding your breath.

When To See A Doctor

Book an appointment if you have symptoms more than twice a week, if you need antacids regularly, or if symptoms persist despite the changes above. Seek prompt medical attention for any of these:

• Difficulty swallowing, or food feeling stuck.
• Unintended weight loss.
• Vomiting blood, or black, tarry stools.
• Persistent vomiting.
• Anaemia.
• Chest pain with exertion, breathlessness, or sweating, treat as a cardiac emergency.
• Symptoms that begin newly after age 50.

Long-term acid-suppressing medication has its place and is sometimes necessary, but it should be a decision made and periodically reviewed with your doctor rather than an indefinite default.

Common Mistakes To Avoid

• Blaming spice for everything: Fat content, portion size, and meal timing usually matter more than chilli.
• Late dinners: Eating at 11pm and sleeping at midnight guarantees reflux regardless of what you ate.
• Stacking pillows instead of raising the bed: It bends the neck without elevating the torso properly.
• Doing crunches for core strength: Reliably provokes reflux; planks and dead bugs work better.
• Living on antacids without investigation: Frequent need for them is information, not a solution.
• Assuming chest pain is reflux: Cardiac causes must be excluded, especially with exertional symptoms.
• Eliminating dozens of foods at once: Unnecessary and hard to sustain. Log, identify two or three real triggers, and keep the rest.
• Ignoring abdominal weight: It is a mechanical driver, and reducing it works.

What To Do This Week

1. Finish dinner at least three hours before bed, every night.
2. Raise the head of your bed by 15 to 20 centimetres.
3. Start sleeping on your left side.
4. Split your two largest meals into four smaller ones.
5. Keep a food and symptom log for 14 days.
6. Replace crunches with planks and dead bugs.
7. Take a 10-minute walk after your biggest meal.
8. Book a doctor's visit if symptoms occur more than twice a week.

FAQ

What is the difference between heartburn and GERD?

Heartburn is the symptom, a burning sensation behind the breastbone. GERD is the chronic condition in which reflux happens frequently enough to cause ongoing symptoms or damage to the oesophagus, usually meaning symptoms more than twice a week.

Which foods should I avoid with acid reflux?

The common triggers are deep-fried and fatty food, chocolate, peppermint, caffeine, alcohol, tomato-based dishes, citrus, carbonated drinks, and large amounts of raw onion or garlic. Triggers vary, so a two-week food and symptom log is more useful than a blanket elimination.

How long before bed should I stop eating?

At least three hours. This is one of the single most effective changes for night-time reflux, alongside raising the head of the bed and sleeping on your left side.

Can exercise make acid reflux worse?

Some exercise can. High-impact running, crunches and sit-ups, inversions such as headstands or long downward dog, and very heavy lifting with breath-holding all tend to provoke symptoms. Walking, cycling, upright strength work, and gentle yoga are usually well tolerated.

Does losing weight help GERD?

Yes, and it is one of the most effective interventions. Abdominal fat increases pressure inside the abdomen, which pushes stomach contents upward, so reducing it addresses a direct mechanical cause.

Which side should I sleep on for acid reflux?

The left side. Because of the anatomy of the stomach and oesophageal junction, left-side sleeping reduces acid exposure compared with sleeping on the right.

Is it safe to take antacids every day?

Regularly needing antacids is a sign to be evaluated rather than to self-treat indefinitely. Acid-suppressing medication is appropriate for many people but should be prescribed and reviewed periodically by a doctor.

Can acid reflux cause a cough or hoarseness?

Yes. Chronic dry cough, hoarseness, a morning sore throat, a lump-in-the-throat sensation, and worsening asthma can all be caused by reflux, sometimes without prominent heartburn.
