Acidity in Ayurveda is called “Amlapitta” — a state in which Pitta, with its hot, sharp and sour qualities, becomes aggravated and “vidagdha” (improperly digested, producing a burning sensation). Burning in the chest or upper abdomen, sour belching, a sour-bitter fluid in the mouth and heaviness are its common signs. Ayurveda’s first step is not a medicine but finding the cause and removing it — meal timing, the kind of food, sleep and the state of mind.

Does someone in your home always keep a bottle of antacid or a sachet of fruit salt handy? Our grandmothers had their own advice: “Don’t eat late at night, don’t lie down right after eating, don’t eat when you are angry.” It sounded like scolding then — yet today both Ayurveda and modern medicine count these very habits among the biggest roots of acidity.

In Issue 012 we saw that the Pitta pulse is felt under the middle finger, and in Issue 011 we discussed the hot and sharp qualities. Today, the same Pitta and the same qualities appear in the story of acidity.

विरुद्धदुष्टाम्लविदाहिपित्तप्रकोपिपानान्नभुजो विदग्धम्।
पित्तं स्वहेतूपचितं पुरा यत्तदम्लपित्तं प्रवदन्ति सन्तः॥

— Madhava Nidana (chapter on Amlapitta)

Meaning: In a person who habitually takes incompatible, spoiled, excessively sour, burning (vidahi) and Pitta-aggravating food and drink, the Pitta already accumulated by its own causes becomes “scorched” (vidagdha) — the learned call this condition Amlapitta.

1. What Ayurveda says — Pitta, Agni and “scorched” digestion

In Ayurveda, Pitta carries the digestive fire (Agni). Balanced Pitta digests food, brings healthy hunger and keeps the intellect sharp. But when Pitta’s hot, sharp, liquid and sour qualities increase and Agni becomes irregular, food is “scorched” rather than properly digested — a state described as vidagdha ajirna. When this keeps repeating, the condition of Amlapitta develops.

Main causes described in the classics (in simple words):

• Incompatible food (viruddha ahara): foods that don’t go together — for example, heavy fried food followed by a cold drink or sweets.
• Too much sour, spicy, fried and salty food: pickles, chutneys, heavy chilli and spice, repeatedly fried items, stale or fermented food.
• Disturbed meal timing: suppressing hunger, eating very late, or eating again before the previous meal is digested (adhyashana).
• Tea, coffee, alcohol, smoking: especially on an empty stomach.
• Late nights and sleeping after meals in the day: staying awake through Pitta’s time (around midnight).
• The mind: anger, irritation, worry and hurry — Ayurveda counts these as Pitta-aggravating too.

Two forms of Amlapitta are described: Urdhvaga (upward — sour belching, sour-bitter vomiting, burning in the throat and chest) and Adhoga (downward — burning in the abdomen, frequent loose stools). Whether Vata or Kapha is also involved changes the Vaidya’s advice.

2. What modern science says

Modern medicine usually links heartburn with acid reflux / GERD — when the “valve” between the stomach and the food pipe (the lower oesophageal sphincter) relaxes and acid moves upward. Burning or pain in the upper abdomen is also described as dyspepsia or gastritis.

• Habits that raise the risk: large meals, lying down soon after eating, late dinners, smoking, alcohol, excess caffeine, very fatty or spicy food, extra weight around the abdomen, tight clothing.
• Some medicines: certain painkillers (NSAIDs) can affect the stomach lining — but never stop a medicine on your own; ask your doctor.
• Infection: a bacterium called H. pylori can cause recurrent gastritis or ulcers — your doctor can test for it.
• Stress and sleep: short sleep and constant stress make symptoms feel worse.

Notice how closely Ayurveda’s list of causes matches science’s list of risk factors — late meals, lying down after food, fried and spicy food, tea and coffee, alcohol, stress. Only the language differs.

3. Everyday habits — what to do and what to avoid

• Eat on time, when hungry: don’t suppress hunger and don’t stuff yourself without it. In Pitta-dominant people, postponing hunger increases burning.
• An early, light dinner: at least 2–3 hours before sleep.
• Don’t lie down right after eating: take a few gentle steps, then sit upright (for example in Vajrasana).
• Leave part of the stomach empty: eat to contentment, not to fullness.
• No tea or coffee on an empty stomach: eat something light or drink water before the first cup. (Read how warm water affects Pitta in Issue 010 — very hot water does not suit Pitta.)
• Eat with a calm mind: not with your phone, an argument or anger.
• Traditional cooling foods: fennel, coriander, amla, coconut water, aged rice, bottle gourd and ridge gourd have long been considered Pitta-pacifying in Indian homes. But who should take what, when and how much should be decided by a qualified Vaidya according to your constitution and condition.

The cold milk, soda and antacid trap: many people feel some relief with cold milk or soda, but it may be short-lived. If you find yourself needing antacids or acidity tablets again and again, it is a sign the cause needs to be investigated — start or stop any medicine only on your doctor’s advice.

4. The seven constitutions — acidity looks different in each

Please don’t decide your constitution from this table — a qualified Vaidya determines Prakriti through examination.

5. Who needs caution — and when to see a doctor right away

If you have any of the following, don’t lose time on home remedies — see a doctor immediately:

• Chest pain or pressure — especially with sweating, breathlessness, or pain spreading to the arm or jaw (it may be a heart problem)
• Black, tar-like stools or vomiting blood
• Difficulty or pain in swallowing, food getting stuck
• Unexplained weight loss, persistent vomiting, anaemia
• Acidity that starts for the first time after age 45–50, or keeps getting worse

Special caution: pregnant women, children, the elderly, and anyone with diabetes, heart disease or kidney disease, or taking painkillers or blood thinners, should try any home or Ayurvedic measure only with advice from their doctor and a qualified Vaidya.

6. This season — why acidity in Hemanta?

In Hemanta (early winter, November–December), Agni is usually strong and appetite is good. Yet this is also the season of festival sweets, fried wedding feasts, late-night dinners and drinking less water in the cold — together they “scorch” Pitta. A strong Agni needs nourishing food on time; starve it or feed it erratically, and the same fire returns as burning.

🩺 7. Nadi Pariksha — recognising the movement of Pitta

In Nadi Pariksha, Pitta is felt under the middle finger, and tradition describes its movement as manduka gati — the jumping, quick movement of a frog. Two people with “acidity” may have very different pulses: one shows Pitta with the restlessness of Vata, another with the heaviness of Kapha. That is why a Nadi Vaidya does not give everyone the same advice for “acidity” — they try to understand the person’s state through rate • rhythm • strength • depth • temperature.

In Nadi Vaidya Dr. Ajit Singh Yadav’s 36+ years of clinical experience, digestive complaints have been among the most common, and advice has always been given after reading the pulse and constitution. The Nadi Vaidya family has experience consulting with people from the film industry, royal families, leading business families and international patients, and Nadi Vaidyas trained at Nadi Vaidya Gurukul now serve in almost every state of India.

“You don’t just touch the pulse — you have to connect with it.”

Read the three-finger method in Issue 012, and if you would like to learn this science yourself, see the Nadi Pariksha course.

Nadi Pariksha is a traditional Ayurvedic holistic assessment method; it is not a substitute for lab tests or modern investigations.

🏡 8. Today’s Practical Experiment — a seven-day “Pitta diary”

• Day 1: Start a diary — what you ate, when, and when the burning came. Just note it; change nothing.
• Day 2: Have dinner 2–3 hours before sleep. Next morning, note the burning and your sleep.
• Day 3: Don’t lie down or slump over your phone after eating — take a short walk.
• Day 4: Don’t have your first tea on an empty stomach — eat something light first.
• Day 5: Eat as soon as you feel hungry — don’t postpone it. Note the difference.
• Day 6: Record your mood — was the burning worse on days of anger, hurry or worry?
• Day 7: Read the whole week — what turned out to be your biggest trigger?

This exercise is self-observation, not diagnosis. If you have any of the warning signs above, or the problem keeps returning, consult a qualified Vaidya or doctor.

Frequently asked questions

What is acidity called in Ayurveda?
Ayurveda calls acidity “Amlapitta” — a state in which Pitta, with its hot, sharp and sour qualities, becomes aggravated and scorched, producing burning and sour belching.

Is cold milk good for acidity?
Some people feel relief for a while, but it doesn’t suit everyone and the relief may be temporary. In Kapha types or those who don’t digest milk well, it can add heaviness. Ask a qualified Vaidya according to your constitution.

Is it okay to take acidity tablets every day?
Needing tablets again and again is a sign that the cause should be investigated. Never start or stop any medicine on your own — follow your doctor’s advice.

When should I see a doctor immediately for acidity?
Chest pain or pressure, black stools, vomiting blood, difficulty swallowing, unexplained weight loss, or acidity starting for the first time after 45–50 — see a doctor right away.

Can the pulse show increased Pitta?
In Nadi Pariksha, the movement of Pitta is felt under the middle finger, helping the Vaidya form a holistic picture of the person’s state. It is a traditional method, not a substitute for lab tests. To learn it, see the Nadi Pariksha course.
