Heartburn, sour regurgitation, difficulty swallowing, chronic cough, and hoarseness are all symptoms of Gastroesophageal Reflux Disease (GERD). This condition occurs when acid or digestive juices from the stomach flow back into the esophagus, causing a burning sensation in the chest and potentially leading to complications.
GERD is common worldwide, affecting people of all ages and genders. It is closely related to eating habits and lifestyle. While patients often rely on antacids, these medications only treat the symptoms at the surface level. In reality, we must address the root cause and find ways to prevent acid reflux. But if you already have it, how should it be managed?
The primary cause of GERD is usually a malfunction of the lower esophageal sphincter (LES), which acts as a barrier preventing acid from flowing back from the stomach into the esophagus. The LES may relax too frequently or become weak, failing to close tightly. Additionally, reflux can be caused by high abdominal pressure from obesity, pregnancy, or tight clothing, or from excessive stomach acid production.
Symptoms of acid reflux range from mild to disrupting daily life. These include heartburn (the most common symptom, a burning sensation in the lower chest that may spread to the throat), acid regurgitation (sensing a sour or bitter taste of gastric juice in the mouth or throat), and dysphagia (difficulty or pain when swallowing food or water). Respiratory symptoms may also occur, such as chronic cough (especially at night), chronic hoarseness, sore throat, a sensation of a lump in the throat, or dental erosion caused by the acid.
Treatment for GERD focuses on relieving symptoms and preventing complications, coupled with behavioral changes.
Lifestyle modification is fundamental to treatment. Start by controlling your diet; avoid triggers such as spicy foods, high-fat foods, alcohol, caffeine, and carbonated drinks. Do not lie down immediately after eating; wait at least 3 hours. Elevate the head of your bed or use a pillow to raise your head about 6-8 inches. Weight loss is recommended for those who are obese, as is quitting smoking.
Medications for treating GERD fall into several groups, each with different mechanisms and indications depending on severity. The first group is Antacids. These are alkaline and neutralize stomach acid, providing immediate relief for heartburn. Examples include Sodium Bicarbonate, Aluminum Hydroxide, Magnesium Hydroxide, and Calcium Carbonate.
Additionally, there are medications containing Alginates, which react with acid to form a gel raft floating on top of the stomach contents, physically preventing acid from refluxing into the esophagus.
The second group is H2 Receptor Antagonists (H2 Blockers), which work by reducing acid secretion. Examples include Famotidine and Cimetidine.
The third group is Proton Pump Inhibitors (PPIs). These are the most effective at reducing acid by inhibiting the enzyme that pumps acid into the stomach. Examples include Omeprazole and Lansoprazole. These are often the first choice for severe GERD. However, they must be taken 30 minutes to 1 hour before a meal. Long-term use may increase the risk of Vitamin B12 deficiency, mineral deficiencies (like Magnesium and Calcium), and osteoporosis.
Furthermore, doctors may prescribe other drugs in combination, such as Prokinetics (drugs that improve gastrointestinal motility). These help increase the contraction of the esophagus and stomach and tighten the lower esophageal sphincter, accelerating the movement of food to the small intestine and reducing reflux. They are often used when GERD is caused by motility disorders.
Although acid reflux may sound mild, if left chronic, it can lead to dangerous complications such as esophagitis and ulcers due to acid damage, esophageal stricture (narrowing caused by chronic inflammation and scarring), or cellular changes in the esophageal lining (Barrett's esophagus), which is a pre-cancerous condition.
Therefore, consult a doctor or pharmacist to receive proper care. Please remember that this disease is largely caused by incorrect lifestyle habits. Thus, treatment must start with adjusting your attitude and lifestyle, as medication may only be a temporary aid.
