A Complete Guide to the Root Causes of Acidity and Its Solution
Published on Fri Feb 20 2026
A burning belly after a late 2 AM pizza party with friends seems relatable? This sensation is due to a condition called acidity. It happens when excess stomach acid irritates the food pipe, causing that familiar burning discomfort.
In most people, acidity commonly occurs as a result of lifestyle habits, dietary preferences, and chronic stress. In many cases, discomfort due to the condition can be managed with over-the-counter medications like antacids. These may provide temporary relief from the concerns. However, if acidity keeps bouncing back even after trying these remedies or making lifestyle adjustments, then it's time to dig deeper. Frequent heartburn might reflect an underlying gut issue.
Common Triggers of Acidity (The Obvious Ones)
If you have started avoiding hearty meals because you are too scared of heartburn, it's time to reflect. Let’s explore what causes acidity to avoid these triggers for a healthy life.
-
Oily, Spicy, and Sour Foods: Your favorite red chilli sauce or tamarind flavor can set your stomach on fire. This is because spicy and sour foods stimulate the stomach to produce acid in excess, leading to the slowing down of digestion. The extra acid can irritate the gut lining and cause acid reflux, resulting in a burning sensation and discomfort. Fatty foods are known to relax the lower esophageal sphincter, the muscle that controls the movement of food and fluids through the gut. When it relaxes too much, the stomach acid rushes back to the gut, causing heartburn.
-
Overeating and Lying Down Immediately After Food: Having food till your stomach hurts or getting to bed soon after a meal can create pressure in the stomach, pushing the acid upwards to the gut and causing heartburn.
-
Late-night Snacking or Skipping Meals: The stomach automatically produces acid at your regular meal time. When you skip a meal, the stomach will still secrete acid, anticipating food. When acid gets released on an empty stomach, it irritates the lining, leading to acidity. Moreover, when you have snacks late at night, they won't get digested properly because digestion slows when you sleep. Lying down also causes the stomach acid to enter the gut, leading to heartburn.
-
Alcohol, Smoking, or Caffeine Addiction: Alcohol irritates the esophageal lining and can even initiate relaxation of the lower esophageal sphincter, causing acidity. Smoking and excessive caffeine intake produce a two-way effect: they can increase gastric secretions and irritation in the stomach.
-
Pregnancy: This period sends your hormones on a roller coaster ride, and the baby bump puts that extra pressure on the stomach, causing the acid to travel upwards. This brings a not-so-pleasant burning sensation to many pregnant women.
-
Some Medicines: Some pain killers, such as ibuprofen or aspirin, may sometimes irritate the stomach lining and increase the risk of acidity and related issues.
-
Poor Sleep and Stress: Research has found that the brain and gut are linked through an axis. Thus, long-standing stress and irregular sleep patterns can alter the body's acid mechanism. This can result in inflammation and trigger acidity due to stress.
These are only surface-level triggers of acidity. Some bells might ring as soon as you consume spicy food items or relish coffee, but the story of acidity runs deeper. Let’s find out.
Why Acidity Keeps Coming Back: Root Causes You Don’t Hear About
If, even after following a healthy diet and lifestyle, acidity won’t just go away, then it points to a deeper health issue. The possible reasons may include:
1. Altered Acid Mechanism
Disrupted acid rhythm occurs when the stomach releases acid at the wrong time. This can happen when your meal timings are irregular, you are experiencing stress, or you often snack late at night. When the gastric juice is released on an empty stomach, it causes a burning sensation. If sufficient acid is not secreted after meals, it can lead to food staying undigested, causing fermentation and gas formation in the stomach. While antacids provide temporary relief, they don’t restore the stomach’s natural acid secretion.
2. Weak Digestive Fire
According to Ayurveda, a weak or imbalanced digestive fire, known as Agni, can disrupt proper digestion. This leads to fermentation, bloating, acid buildup, and toxin (ama) formation in the stomach. Even a light meal will make your stomach feel full, especially if you consume cold or processed foods. Antacids or enzyme tablets can only temporarily suppress the discomfort. Long-term relief can only be achieved by strengthening Agni through a combination of Ayurvedic remedies, diet, and lifestyle changes.
3. Inflammation in Gut Lining
Regular consumption of spicy foods and certain medications like NSAIDs (Non-steroidal anti-inflammatory drugs), or chronic stress can irritate and erode the stomach lining, ultimately leading to inflammation. When the protective lining is gone, the acid comes into contact with the sensitive tissues, causing burning and aggravating the inflammation. Antacids may help suppress the issues, but they can’t restore the stomach lining.
4. Bacterial Imbalance (Dysbiosis)
Research has shown that there is a direct connection between gut microbiota and digestion. The beneficial microbes promote digestion and aid in maintaining good gut health. An overgrowth of harmful bacteria can lead to digestive issues like fermentation of the food, bloating, acid reflux, and even inflammation of the gut. If you often feel bloated after consuming sweets or milk, it could be a sign of gut dysbiosis. Taking antacids can only help relieve the acidity concerns, but they won't help reduce the harmful bacterial growth.
5. Gut-Brain Axis & Stress
Feeling bloated or heavy as exams are just around the corner or before an important presentation at work? Your intestine and mind are always connected either through nerve signals, hormonal secretions, or the microbiome. Stress activates the fight-or-flight response, which can increase stomach acid and alter gut movement. Medicines can reduce the issues but fail to address the brain-gut connection.
Ayurvedic Perspective on the Root Causes
Are you feeling bloated, gassy, or struggling with heartburn? Ayurveda believes these concerns are more than just digestive issues; they’re signs that your body’s inner balance, or dosha, is off. When you have acidity, it relates to Pitta, which governs your body’s heat and metabolism. Gas is linked to Vata, reflecting movement and flow, while slow digestion points to Kapha, associated with heaviness and stability.
It’s important to remember that acid isn’t the problem here; it actually plays a crucial role in breaking down food and helping the body absorb nutrients. Ayurvedic plan aims to rekindle the Agni, or digestive fire, which helps keep everything balanced.
Instead of relying on medicines to suppress acid, Ayurveda emphasizes restoring balance. This includes consuming easy-to-digest foods for Pitta, gentle movement for Vata, and lighter, warm meals for Kapha. By focusing on mindful eating, keeping regular routines, and managing stress, you not only relieve discomfort but also boost nutrient absorption and overall gut health.

FAQs
- What causes acidity in the stomach?
Main causes of acidity are the consumption of spicy and greasy foods, not having proper eating routines, high levels of stress, and addiction to tobacco or alcohol.
- Can stress cause acidity?
Yes, stress may contribute to acidity by altering the digestive tract’s natural rhythm and stimulating gastric acid secretion. It also affects digestion and gut sensitivity, making you more prone to that burning sensation.
- Why do I get acidity even after eating healthy?
If you get acidity despite healthy eating choices, then it means that the root cause is something else. Irregular eating habits, low digestive fire (agni), inflamed gut lining, and stress can cause heartburn even with a healthy diet.
- Do spicy foods cause acidity permanently?
Spicy foods alone can’t cause an acidity problem for a long period. They might stimulate acid reflux, heartburn, or irritation temporarily, mainly if your gut’s protective lining is more sensitive.
- How do I fix acidity without tablets?
You can fix acidity without tablets by eating light and easily digestible meals, avoiding triggers like oily or spicy foods, managing stress through practices like yoga or pranayama, and supporting digestion with natural aids such as probiotics or herbs.
- Is acidity related to gut health?
Certainly! Acidity reasons are deeply related to gut health. A deranged gut flora, low digestive fire, or an inflamed gut lining can stimulate excessive stomach acid or make your stomach sensitive to it.
