Understanding Acid Reflux: Causes, Symptoms, and Effective Treatments for GERD

Acid reflux occurs when stomach acid flows back into the esophagus and irritates its lining. This can cause occasional heartburn, a burning pain in your chest, just behind your breastbone, or a bitter taste in the throat. If left untreated, heartburn can lead to a more serious condition known as gastroesophageal reflux disease (GERD), which can, in turn, lead to more severe conditions, such as esophageal cancer.

GERD, a prevalent gastrointestinal condition in the United States, impacts over 20% of the population. Fortunately, GERD can be effectively managed through various approaches, including empowering lifestyle modifications, medications, and, in more severe instances, surgery.

The Journey of Stomach Acid: From Reflux to GERD

To understand acid reflux, we need to understand the organs involved in this problem: the mouth, the throat, the esophagus, and the stomach. 

Let’s start backward. 

The stomach is part of the gastrointestinal tract and plays an important role in digestion. Its function is to break down food mechanically by contracting the muscles and chemically by secreting enzymes and acids. Once the food is broken down, it passes to the small intestine to continue the process. The food is supposed to travel throughout the gastrointestinal tract in one way. The system has several sphincters (involuntary muscles) that close after the food moves forward to prevent the food from going backward.

The esophagus is the muscular tube through which food passes from the throat to the stomach. To prevent stomach contents from moving back up, the esophagus has a sphincter, the lower esophageal sphincter (LES), a ring of involuntary muscles at the bottom of the esophagus where it meets the stomach. Typically, the LES relaxes, allowing food and liquid to pass into your stomach and close tightly. 

The stomach may produce up to three to four liters of secretions daily. Those secretions are very acidic and essential in digestion, helping dissolve the food. Stomach acid does not cause problems if it is present in the stomach because its special lining tolerates that amount of acid. When the LES weakens or relaxes inappropriately, gastric secretions with or without food can flow back into the esophagus. The esophagus has a different lining that is not meant to be in contact with stomach acid and does not tolerate it well. When this happens, the esophagus gets irritated, leading to a burning sensation in the chest known as heartburn or, in some cases, a bad taste and burning sensation in the throat.

According to the frequency of the acid's contact with the esophagus lining, the damage may range from irritation to small burns that the body can heal to burns that don't heal properly because the wound comes into contact with more acid, making the burn more extensive and more profound. The compromised linen extends beyond the esophagus to the throat, larynx, and respiratory system. In more advanced cases, the body reacts by healing the lower part of the esophagus with a different type of lining, similar to the cells that line your intestines. This is a precancerous condition called Barrett's esophagus that increases the risk of developing esophageal cancer called adenocarcinoma. 

Identifying Risk Factors and Symptoms of GERD

Occasional acid reflux and heartburn are not considered diseases. However, if the problem becomes recurrent and the symptoms worsen, it is regarded as a gastroesophageal-related disease (GERD).

Several risk factors make you develop GERD or make your symptoms worse.

  • Being overweight or obese
  • Hiatal hernia
  • Smoking
  • Eating fatty foods
  • Drinking alcohol, coffee, or carbonated beverages
  • Lying down within 3 hours of eating
  • Some medications, such as sedatives, antidepressants, asthma, and high blood pressure medications, include calcium channel blockers.

When to Seek Medical Help for Acid Reflux

It is time to see your primary doctor´s help if 

  • The sensation happens more than twice a week and lasts several hours.
  • The symptoms don´t relieve with  lifestyle changes and over-the-counter medicines even if you take it more than twice a week 
  • Disrupt your sleep and daily activities.
  • You should seek medical attention if you experience more severe symptoms, such as nausea, vomiting, the sensation of a lump in the throat, pain, difficulty swallowing, unexpected weight loss, or symptoms such as hoarseness and cough that you may not associate with acid reflux. These symptoms could indicate a more serious condition and should not be ignored.

Potential Complications of Untreated GERD

GERD itself isn't life-threatening, but if left untreated, it can lead to some severe complications. Here are the main complications of GERD:

  • Esophagitis is the inflammation of the esophagus lining. Symptoms include heartburn, chest pain, and difficulty swallowing. 
  • Esophageal stricture: Over time, the inflammation caused by acid reflux can scar the esophagus. This scarring can narrow the esophagus, making it difficult to swallow.
  • Barrett's esophagus: This is a precancerous condition that develops in some people with GERD. In Barrett's esophagus, the cells in the lining of the lower esophagus change to resemble intestinal cells. While Barrett's esophagus itself doesn't cause any symptoms, it increases your risk of developing esophageal cancer.
  • Reflux laryngitis: Acid reflux can irritate the throat and the vocal cords, causing hoarseness and a chronic cough. This acid reflux usually happens at night when you’re asleep. 
  • Dental problems: Acid reflux can erode tooth enamel, leading to cavities and other dental problems, bad breath, and mouth pain or sensitivity
  • Sleep problems: Acid reflux can disrupt sleep, causing heartburn and discomfort at night.

Diagnosing GERD: Methods and Tests

Your primary care physician may diagnose GERD clinically based on your symptoms and risk factors. If you have severe symptoms or a poor response to the treatment, your doctor may refer you to a gastroenterologist. They will perform other diagnostic methods, such as pH monitoring or upper endoscopy, to diagnose possible GERD complications and exclude other pathologies that may mimic GERD symptoms, such as eosinophilic esophagitis, H. Pylori infection, Barett’s esophagus, or adenocarcinoma. 

pH monitoring involves placing a small device in your esophagus that measures the amount of acid present over a 24-hour period. Upper endoscopy is a procedure in which a thin, flexible tube with a camera is inserted into your esophagus to examine the lining and look for any abnormalities.

Effective Treatments for GERD: Lifestyle Changes, Medications, and Surgery

The treatment is adapted to several factors, such as the severity of the disease and its associated cause. Doctors recommend lifestyle changes and weight loss as first steps, followed by medications such as antacids, H2 Blockers, and Proton pump inhibitors (PPIs), which are effective in most cases. They will recommend surgery only in cases where the patient has an anatomical cause, such as a hiatal hernia that needs to be repaired, complications of GERD, or severe uncontrolled regurgitations. 

Practical Lifestyle Changes for Managing GERD 

  • Diet Modification:

    • Avoiding Trigger Foods: Certain foods can trigger acid reflux symptoms. Individuals with hiatal hernia and GERD are advised to avoid acidic, spicy, and fatty foods. Citrus fruits, tomatoes, chocolate, and caffeinated beverages are examples of potential triggers.

    • Smaller, Frequent Meals: Consuming small, more frequent meals throughout the day can help reduce the pressure on the stomach and minimize the chances of acid reflux.

    • Meal Timing: Avoiding meals (any size) shortly before bedtime can prevent stomach contents from flowing back into the esophagus during the night when the symptoms are presented more frequently

  • Weight Management:

    • Excess weight can contribute to increased abdominal pressure, which may exacerbate hiatal hernia and GERD symptoms. Adopting a healthy and balanced diet and regular physical activity can aid in weight management and symptom improvement.
  • Elevating the Head of the Bed:

    • Raising the head of the bed by about six to eight inches can help prevent stomach acid from flowing back into the esophagus during sleep. This position reduces the effect of gravity on the stomach contents.

Medications for GERD: PPIs and H2 Blockers

Proton Pump Inhibitors (PPIs), such as omeprazole, esomeprazole, lansoprazole, and pantoprazole, are commonly prescribed to manage acid reflux associated with hiatal hernia and GERD. These medications work by inhibiting the production of stomach acid, thereby reducing the acidity levels in the stomach and minimizing the likelihood of acid reflux into the esophagus. PPIs are often effective in providing relief from symptoms like heartburn and regurgitation.

Histamine-2 (H2) blockers, including ranitidine, famotidine, and cimetidine, are another class of medications used to reduce stomach acid production. By blocking the action of histamine, a substance that stimulates acid secretion, H2 blockers help alleviate symptoms associated with GERD. While not as potent as PPIs, H2 blockers can still effectively manage acid reflux.

Surgical Options for Severe GERD

According to the endoscopy and pH monitoring, the gastroenterologist will recommend additional treatment, sometimes strengthening the lower esophageal sphincter or correcting the hiatal hernia. The surgeon chooses the technique according to the patient’s conditions and surgery indications. Fundoplication is a surgical procedure commonly used to treat GERD associated with hiatal hernia. 

Conclusion: Importance of Early Intervention and Regular Checkups

If you experience frequent heartburn that doesn’t improve with over-the-counter medications, it is essential to see a doctor for an adequate diagnosis and personalized treatment. Mild GERD may be treated effectively with medications and lifestyle changes. Unfortunately, GERD may be a recurrent, long-term condition that can lead to several complications, including Barrett's esophagus, which is associated with an increased risk of developing esophageal cancer. 

Although the risk of developing esophageal cancer is small, it's important to have regular checkups with careful imaging and extensive biopsies of the esophagus to check for precancerous cells (dysplasia). If precancerous cells are discovered, they can be treated to prevent esophageal cancer. Early intervention can help to avoid serious complications, reduce symptoms, and improve your quality of life.
