Acid Reflux: Everything You Need to Know About Causes, Symptoms, and Treatment

Heartburn or Acid reflux is one of the most commonly experienced digestive ailments among many millions of people of all ages around the world. In this case, there is an involuntary backward flow of the stomach acid from the stomach towards the food pipe (esophagus). This process leads to irritation of the esophagus and gives rise to burning sensation in the middle of the chest, bitter taste, regurgitation, and sometimes troubles with swallowing food and liquids. However, some episodes of reflux are normal and happen due to the overeating of meals, lying down after eating, and other reasons.

Gastroesophageal Reflux Disease or GERD is one of the most common conditions, which is characterized by the prolonged period of the backward flowing of the stomach acid towards the esophagus. This disease arises because of the weakening of the muscle of the lower esophageal sphincter (LES) which normally keeps the stomach contents inside.

What Is Acid Reflux?

Acid reflux is a condition that results from an improperly closed lower esophageal sphincter (LES). The LES is a circular muscle found between the esophagus and the stomach and is responsible for opening to let food into the stomach and closing tightly to ensure that no contents flow back into the esophagus.

If the LES weakens and fails to close appropriately, stomach acid is allowed to move backwards into the esophagus. As a result, the esophagus, which is not meant to withstand stomach acid, becomes irritated and inflamed leading to heartburn.

Acid reflux can be experienced once in a while, but when it happens two times a week or more often, one is suffering from GERD and needs to see a medical practitioner.

How Does Acid Reflux Happen?

The body automatically manufactures hydrochloric acid for the purpose of digesting food. This acid is kept within the stomach by various protective features including the lower esophageal sphincter.

Acid reflux occurs when all these protective measures are overwhelmed. Various reasons contribute to increasing the pressure on the stomach or weakening the LES, leading to the upward movement of stomach acids.

Common situations that trigger reflux include:

• Eating large meals

• Lying down immediately after eating

• Consuming fatty or spicy foods

• Drinking excessive caffeine or alcohol

• Smoking

• Being overweight or obese

• Pregnancy

• Certain medications that relax the LES

Over time, untreated acid reflux may damage the esophagus, making early management important.

Common Causes of Acid Reflux

Although anyone can experience acid reflux occasionally, certain factors make it more likely. By understanding these causes, you can take practical steps to reduce symptoms and protect your digestive health.

Poor Eating Habits

Large quantities of food, rapid consumption of food, or late-night consumption of food can increase the strain on your stomach. If your stomach becomes overstuffed, then chances are increased for acid to be pushed up into the esophagus. In a similar manner, when you lie down immediately after eating, you do not give yourself enough time for gravity to do its work.

Certain Foods and Drinks

There are some foods and beverages that can cause acid reflux by relaxing the LES or causing increased production of acid in the stomach. Some common foods that can cause acid reflux are spicy foods, fried foods, fatty foods, chocolates, citrus fruits, tomatoes, caffeinated products, alcoholic products, and peppermint. Different people have different triggers. One way of identifying your triggers is by maintaining a food diary.

Excess Body Weight

Obesity and being overweight increase abdominal pressure, and as such, the abdominal contents are forced upwards. The increased pressure makes it easy for the acid to travel up the esophagus, hence causing acid reflux problems. Losing some weight may help to alleviate the problem.

Smoking

There are two ways through which smoking causes acid reflux, including weakening the LES so that it is unable to keep the stomach contents in check and reducing the amount of saliva secreted. Saliva normally acts as a natural antidote to acid, hence the need for more saliva to protect the esophagus.

Pregnancy

Acid reflux commonly occurs in pregnant women because hormones tend to relax the LES muscle while the enlarged uterus causes pressure on the abdomen. Although acid reflux is common in pregnant women, it can be easily controlled through changes in diet and eating small portions of food.

Certain Medical Conditions

In addition, some medical issues may increase the chances of developing acid reflux. For instance, a hiatal hernia involves the protrusion of the upper portion of the stomach into the chest region, thus decreasing the effectiveness of the valve separating the two organs. Furthermore, gastroparesis involves delayed stomach emptying, hence allowing the acid and foods to stay in the stomach for too long, leading to an increased likelihood of reflux. 

Important Fact: Acid reflux is affected by different aspects of life, such as diet and health issues.

Signs and Symptoms of Acid Reflux

The symptoms associated with acid reflux may differ significantly from one patient to another. There might be those who suffer mild discomfort at times, but there are people who have persistent symptoms that affect their lives negatively. It is important to know about these symptoms since they may point to GERD.

Heartburn

The most common symptom is heartburn, a burning sensation in the chest that often occurs after meals or when lying down. It results from stomach acid irritating the lining of the esophagus.

Sour or Bitter Taste

Many people notice a sour or bitter taste in the mouth, especially after regurgitation. This happens when stomach acid travels upward and leaves an unpleasant aftertaste.

Regurgitation

Regurgitation of food or stomach acid is another hallmark symptom. It feels as though partially digested food or liquid is coming back up into the throat or mouth.

Difficulty Swallowing

Known medically as dysphagia, difficulty swallowing occurs when acid reflux causes inflammation or narrowing of the esophagus, making it harder for food to pass smoothly.

Frequent Burping and Bloating

Excessive burping and bloating after meals are common, as trapped gas and acid irritate the digestive tract.

Nausea After Meals

Some individuals experience nausea, particularly after eating large or fatty meals. This can be accompanied by discomfort or even vomiting in severe cases.

Chronic Cough and Hoarseness

Acid reflux can irritate the throat and vocal cords, leading to a chronic cough, hoarseness, or even voice changes. These symptoms are often worse in the morning due to nighttime reflux.

Sore Throat

A sore throat, especially noticeable upon waking, is another sign of acid reflux. Acid exposure during sleep can inflame the throat lining.

Sensation of Food Stuck

Some people describe the feeling that food is stuck in the throat or chest. This can be due to swelling or narrowing of the esophagus caused by repeated acid irritation.

Medical Treatment for Acid Reflux

If lifestyle changes alone do not provide enough relief, your healthcare provider may recommend medication based on the severity and frequency of your symptoms.

Antacids

Antacids provide quick relief by neutralizing stomach acid. They are best suited for occasional heartburn but do not treat the underlying cause of acid reflux.

H2 Receptor Blockers

These medicines reduce acid production in the stomach and provide longer-lasting relief than antacids. They are often recommended for mild to moderate symptoms.

Proton Pump Inhibitors (PPIs)

Proton Pump Inhibitors (PPIs) are among the most effective medications for frequent acid reflux and GERD. They work by blocking the stomach's acid-producing pumps, allowing the esophagus time to heal while reducing heartburn and acid regurgitation.

Commonly prescribed PPIs include:

Lanzol (Lansoprazole)

The medication Lanzol (Lansoprazole) is used to decrease the level of stomach acid secretion and is usually prescribed in the treatment of gastroesophageal reflux disease, ulcers in the stomach and erosive esophagitis. Usually, it is taken before meals and gives good results when it is used properly.

Pantodid Tablets(Pantoprazole)

Another PPI drug – Pantodid Tablets (Pantoprazole) is also popular among doctors and reduces acid secretion, eliminates constant heartburn and heals esophagus.

Itorihenz SR(Itopride)

Itorihenz SR (Itopride) is helpful in ensuring proper gastrointestinal tract motility by speeding up the process of emptying of the stomach contents to the intestines. This will assist in preventing problems such as abdominal bloating, heartburn, discomfort due to feeling full, and acid reflux due to delayed gastric emptying.

Important: Prescription medications should only be used under the guidance of a qualified healthcare professional. The right treatment depends on your symptoms, medical history, and the underlying cause of your acid reflux.

Final Thoughts

Acid reflux is prevalent but any occurrence that recurs frequently is one that requires attention. Understanding what causes acid reflux, recognizing the signs, and making changes to your diet and general lifestyle can significantly alleviate any symptoms.

Taking small portions of food, being in good body shape, staying away from specific types of foods, and not lying on your bed right after eating are some ways to prevent acid reflux. If these methods do not work, then you should take medications prescribed by your doctor including antacids, H2-blockers, proton pump inhibitors (Lanzol and Pantodid), and prokinetics (Itorihenz SR).

Consult a physician when your reflux occurs more than twice a week, difficulty swallowing, inexplicable weight loss, continuous chest pains, and symptoms which do not go away even after taking drugs.
