What Is Acid Reflux? Symptoms, Causes, Treatment & Remedies

What Is Acid Reflux?

Your stomach naturally produces acid to help break down food. Normally, the lower oesophageal sphincter (LES) prevents this acid from travelling upwards.

During digestion, the lower oesophageal sphincter (LES) acts like a one-way valve, allowing the food to enter the stomach while preventing stomach contents from flowing back up. Acid reflux occurs when this valve weakens or relaxes at the wrong time, allowing stomach acid to move into the oesophagus.

Why Does Acid Reflux Happen?

Acid Reflux can happen when the LES doesn't function properly, and the stomach acid can escape into the oesophagus, causing irritation and discomfort. Several factors can increase the likelihood of acid reflux, such as:

• Eating large or heavy meals.
• Consuming spicy, fatty, or acidic foods.
• Drinking alcohol, caffeinated beverages, or fizzy drinks.
• Lying down soon after eating.
• Being overweight or pregnant, which increases pressure on the stomach.
• Smoking may weaken the LES.
• A hiatal hernia or certain medications that relax the LES.

Is Acid Reflux the Same as GERD?

No, acid reflux and GERD are not the same, although they are closely related.

• Acid reflux refers to the occasional movement of stomach acid upwards into the oesophagus, often after eating or lying down. Most people experience this mild discomfort from time to time.
• GERD (Gastro-oesophageal Reflux Disease) is a persistent, long-term condition where acid reflux occurs frequently, typically twice a week or more, or leads to inflammation and damage of the oesophageal lining. GERD may require medical treatment to manage symptoms and prevent complications.

What Are the Common Symptoms of Acid Reflux?

Acid reflux happens when acid from your stomach flows back into your oesophagus and irritates its lining.

These are the common symptoms you may experience:

• Heartburn: A burning pain in the center of your chest, often rising towards your throat. It may get worse after eating, bending over, or lying down.
• Regurgitation: A sour or bitter taste, or a small amount of food, rising back into your throat or mouth.
• Chest pain: Discomfort that sometimes feels similar to heart problems.

Note: If you have sudden, severe chest pain, especially with sweating, jaw pain, or pain spreading to the arm, seek emergency help immediately. Do not assume it is acid reflux.

What Are the Uncommon Symptoms of Acid Reflux?

Atypical symptoms of acid reflux are signs that appear outside the chest and don’t include heartburn. These symptoms often affect your throat, voice, or breathing, so they can be mistaken for other problems.

How Does Acid Reflux Affect the Throat?

Acid reflux damages the throat by exposing its sensitive tissues to harsh stomach acid and digestive enzymes. This ongoing irritation can lead to a condition called Laryngopharyngeal Reflux (LPR).

Note: Laryngopharyngeal reflux (LPR) occurs when stomach acid and active digestive enzymes (like pepsin) rise into the throat and voice box, irritating these delicate areas. Unlike typical acid reflux, LPR usually does not cause heartburn. Instead, it triggers symptoms such as ongoing hoarseness, frequent throat clearing, coughing, and a constant sensation of a lump in the throat.

Common symptoms of LPR include:

• You notice your voice is persistently hoarse or gravelly.
• You feel the need to clear your throat often.
• You develop a chronic cough or a tickle in your throat.
• You sense a lump, mucus, or pill stuck in your throat (globus sensation).
• You find it mildly difficult to swallow.
• You experience post-nasal drip or excess phlegm.

Note: It’s important not to confuse GERD and LPR: GERD mainly causes heartburn in the lower oesophagus, while LPR affects the throat and voice box, often without any heartburn.

How Does Acid Reflux Affect the Voice?

Acid reflux can affect your voice by causing stomach acid and digestive enzymes to reach the larynx and vocal cords. This repeated exposure irritates and inflames these sensitive tissues, making the vocal cords swell and function less efficiently. As a result, your voice may sound hoarse, weak, or rough.

Common vocal symptoms include:

• Hoarseness: Your voice sounds raspy or rough, especially in the morning.
• Vocal fatigue: Your voice feels weak or tires easily, especially after speaking for a short time.
• Reduced range: You find it harder to reach high or low notes, especially if you use your voice a lot at work.
• Frequent throat clearing: You often feel the need to clear your throat or feel a lump.

What Causes Acid Reflux?

Acid reflux happens when the LES (the muscle between your oesophagus and stomach) becomes weak or relaxes when it should not. This lets stomach acid and partially digested food move back up into your oesophagus, leading to irritation and discomfort.

The table below shows the most common causes and triggers, and how they cause acid reflux:

Long-Term Risks of Chronic Acid Reflux

Chronic acid reflux can cause serious problems. It may lead to inflammation or ulcers in the oesophagus (oesophagitis), narrowing from scar tissue (stricture), or Barrett’s oesophagus, a change in the lining of the food pipe that, in a small number of people, can increase the risk of cancer over time. Regular monitoring can catch this early. Acid can also reach the airways, causing breathing issues, or the mouth, leading to dental erosion.

What Are the Treatments for Acid Reflux?

You can treat acid reflux by eating smaller meals, avoiding trigger foods, keeping a healthy weight, and sleeping on your left side. If these changes do not control your symptoms, you can use medicines, either over-the-counter or prescribed by your doctor, to reduce or block stomach acid.

Different types of medicines can help manage acid reflux. The table below shows common options and how they work:

Note: Antacids provide quick relief but should not be relied on long-term, as overuse can mask underlying issues and may cause side effects.

How to Control Acid Reflux?

Managing acid reflux isn't just about finding quick relief; it's about identifying and reducing the factors that trigger it. Simple, consistent lifestyle changes can help minimise reflux episodes and support better digestive health over time. Here are some ways to control acid reflux:

• Eat smaller, more frequent meals instead of large portions.
• Avoid foods and drinks that trigger your symptoms, such as fried foods, spicy dishes, chocolate, coffee, alcohol, and carbonated beverages.
• Wait at least two to three hours after eating before lying down or going to bed.
• Maintain a healthy weight to reduce pressure on the stomach.
• Sleep with your head slightly elevated to help prevent acid from travelling upwards during the night.
• Quit smoking, as it can weaken the lower oesophageal sphincter (LES).
• Manage stress through relaxation techniques, regular exercise, or yoga, as stress may worsen digestive symptoms.
• If lifestyle changes aren't enough, your doctor may recommend medications such as antacids, H2 blockers, or proton pump inhibitors (PPIs).

Along with symptom relief, paying attention to your eating habits, sleep, stress levels, and overall lifestyle can help address the root causes of acid reflux and reduce the chances of recurring episodes.

Which Home Remedies Help with Acid Reflux?

You can manage acid reflux at home by making small changes to your routine. Stay upright for 2 to 3 hours after eating, elevate the head of your bed, and have smaller, more frequent meals to reduce pressure on your stomach. These steps can bring quick relief.

Some foods and simple remedies can help soothe acid reflux at home. Consider these options:

• Ginger: Soothes the stomach and reduces nausea; try ginger tea or chew fresh ginger.
• Bananas and melons: Low-acid fruits that help coat the stomach and neutralise acid.
• Oatmeal: High in fibre, absorbs stomach acid, and rarely triggers reflux.
• Sugar-free gum: Chew after meals to increase saliva production, which helps wash down acid.
• Baking soda: Mix half a teaspoon in water for quick, temporary relief by neutralising acid.

Note: Use baking soda (sodium bicarbonate) only occasionally, not as a daily fix. Avoid it if you have high blood pressure, kidney problems, or are on a low-sodium diet.

Note:

Simple lifestyle changes can make a big difference in managing acid reflux. Try these steps:

• Finish eating at least three hours before you go to bed.
• Sleep with your head and upper body raised on a firm foam wedge or use bed risers (6 to 8 inches) under the head of your bed frame.

Note: Avoid simply stacking regular pillows, as this can strain your neck and increase stomach pressure.

• Limit or avoid trigger foods and drinks.
• Wear loose-fitting clothing to prevent pressure on your stomach.
• Lose excess weight to reduce pressure on your stomach.

Which Yoga Poses Help with Acid Reflux?

Yoga can help ease acid reflux by calming your nervous system, lowering stress, and gently supporting digestion. The best poses keep your chest elevated and avoid inversions or any poses that put strong pressure on your abdomen, as these can push acid upward and worsen reflux.

The table below highlights some of the most effective options and why they work:

Note: For anyone with reflux or a weak LES, modify yoga poses that involve deep forward folding or abdominal compression. Keep your chest slightly elevated and avoid positions that put your head below your stomach to prevent symptoms from worsening.
