Acidity, heartburn and gas are among the most common reasons Indians reach for a medicine. Occasional acidity is usually harmless, but frequent symptoms may point to GERD or an ulcer.

Common symptoms

  • Burning in the chest or upper stomach (heartburn)
  • Sour or bitter taste in the mouth
  • Burping, bloating and fullness
  • Nausea after meals

What triggers acidity?

  • Large, late or spicy, oily meals
  • Lying down soon after eating
  • Tea, coffee, alcohol and smoking
  • Excess weight and pregnancy
  • Painkillers such as ibuprofen, diclofenac and aspirin
  • Stress and irregular meals

Lifestyle changes that work

  1. Eat smaller meals and finish dinner 2–3 hours before bed.
  2. Raise the head end of your bed by 6–8 inches.
  3. Lose weight if you are overweight.
  4. Limit fried food, tea, coffee and alcohol; stop smoking.
  5. Do not lie down right after eating.

Simple remedies like cold milk or saunf may soothe mild symptoms for some people, but they do not treat the underlying cause.

Medicines for acidity

TypeExamplesHow they help
AntacidsDigene, Gelusil, ENONeutralise acid quickly; for occasional use
PPIsPantoprazole (Pan 40, Pantocid), rabeprazole (Razo), omeprazole (Omez), esomeprazole (Nexpro)Reduce acid production; for GERD and ulcers
PPI + prokineticPan-D, Razo-DAdd domperidone for bloating and nausea

PPIs work best taken 30–60 minutes before breakfast. Long-term daily use without review can lower magnesium and vitamin B12 and may increase fracture risk, so take them only as long as your doctor advises. Domperidone can affect heart rhythm, so it should be used at the lowest dose for the shortest time.

Warning signs: see a doctor soon

  • Difficulty or pain while swallowing
  • Unintended weight loss
  • Vomiting blood, or black, tarry stools
  • Persistent symptoms after age 45–50
  • Chest pain with sweating or breathlessness (call 108 or 112, as this may be a heart attack)

Your doctor may advise an endoscopy.

When to see a doctor

See a general physician or gastroenterologist if you need acidity medicines more than twice a week or have any warning sign.

Acidity or something else?

Burning in the upper abdomen is not always acidity. Gallstones, pancreatitis and heart problems can cause similar pain. Pain that spreads to the arm, jaw or back, or comes on with exertion, sweating or breathlessness, needs emergency care.

H. pylori: a common hidden cause

Helicobacter pylori is a bacterium that infects the stomach lining of a large share of Indians. It can cause ulcers and long-term gastritis. If you have recurrent ulcer-type symptoms, your doctor may test for H. pylori and treat it with a combination of antibiotics and a PPI for 10–14 days.

Acidity in pregnancy

Heartburn is very common in pregnancy, especially in later months. Small frequent meals, avoiding lying down after eating and sleeping with the head raised help. Many antacids are considered safe, but check with your gynaecologist before taking any medicine.

Acidity and painkillers

If you need regular painkillers such as ibuprofen, diclofenac or aceclofenac, ask your doctor whether you need stomach protection with a PPI, or whether a gentler option like paracetamol would work.

Foods that commonly help or hurt

Often helpsOften worsens
Oats, poha, idli, curd riceDeep-fried snacks and heavy gravies
Bananas, papaya, melonsCitrus juices and tomato-heavy dishes (for some people)
Coconut water, buttermilkTea, coffee, colas and alcohol
Steamed vegetables, dalVery spicy food and late-night meals

Everyone's triggers differ, so keep a simple food diary for two weeks.

Myths and facts

  • Myth: "Acidity is caused by too much acid only." Fact: Often the valve between the food pipe and stomach is weak, letting normal acid flow upward.
  • Myth: "Cold milk cures acidity." Fact: It may soothe briefly but can worsen acid later in some people.
  • Myth: "Pan-D is just a stronger Pan 40." Fact: Pan-D contains an extra medicine (domperidone) with its own side effects.

Frequently asked questions

What is Pan 40 used for?

Pan 40 contains pantoprazole 40 mg and is used for acidity, GERD and ulcers. It works best taken before breakfast.

What is the difference between Pan 40 and Pan-D?

Pan 40 contains only pantoprazole. Pan-D adds domperidone, which helps with bloating and nausea.

Can I take acidity tablets daily?

Only as long as your doctor advises. Long-term use without review can cause side effects.

When is acidity serious?

See a doctor for difficulty swallowing, weight loss, vomiting blood, black stools or chest pain with sweating.
