Gastroesophageal Reflux Disease (GERD): Causes, Symptoms, and Modern Treatment Options

Gastroesophageal reflux disease (GERD) is one of the most common digestive disorders. It occurs when stomach acid frequently flows back into the esophagus, causing irritation of its lining and leading to symptoms such as heartburn, chest pain, and difficulty swallowing.

Professor Dr. Nabil Dweidar, Professor of Gastrointestinal Surgery and Endoscopy at the Medical Research Institute, Alexandria University, emphasizes that early diagnosis of GERD significantly helps prevent complications and improves the patient’s quality of life.

ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ

What Is Gastroesophageal Reflux Disease?

GERD is a medical condition that occurs due to weakness of the lower esophageal sphincter, allowing stomach acid to move upward into the esophagus.

Dr. Nabil Dweidar explains that the condition may begin mildly but can worsen over time if not properly treated, potentially affecting the esophagus in the long term.

Causes of GERD

Several factors can contribute to GERD, including:

• Weakness of the lower esophageal sphincter

• Obesity and overweight

• Eating heavy meals before bedtime

• Smoking

• Excessive consumption of caffeine and carbonated drinks

• Pregnancy

• Certain medications that relax the esophageal sphincter

• Hiatal hernia

Dr. Nabil Dweidar confirms that an unhealthy lifestyle is one of the main contributors to worsening symptoms.

Symptoms of GERD

Symptoms vary from person to person and may include:

• Severe heartburn

• Regurgitation of food or liquids into the mouth

• Difficulty swallowing

• Chest pain

• Chronic cough or hoarseness

• Recurrent sore throat

• Bitter taste in the mouth

Dr. Nabil Dweidar emphasizes that persistent symptoms require medical evaluation to avoid complications.

ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ

Complications of GERD

If left untreated, GERD may lead to serious complications, such as:

• Chronic esophagitis

• Esophageal ulcers

• Esophageal narrowing and swallowing difficulties

• Barrett’s esophagus

• Increased risk of esophageal cancer in advanced cases

Dr. Nabil Dweidar stresses that early control of the disease prevents these complications.

How Is GERD Diagnosed?

Diagnosis includes several steps:

• Clinical examination and medical history

• Trial of medication and monitoring response

• Upper endoscopy

• Esophageal pH monitoring

• Imaging studies in some cases

Dr. Nabil Dweidar explains that endoscopy is one of the most accurate tools for assessing esophageal damage.

Treatment Options for GERD

Treatment depends on severity and includes:

Lifestyle Modifications

• Weight loss

• Avoiding fatty and spicy foods

• Not lying down immediately after meals

• Elevating the head during sleep

• Reducing caffeine intake and quitting smoking

Medications

• Acid-suppressing drugs (proton pump inhibitors)

• Medications that improve digestive motility

Endoscopic or Surgical Treatment

In severe or resistant cases, surgical or advanced endoscopic interventions may be required.

Dr. Nabil Dweidar emphasizes that selecting the appropriate treatment depends on a comprehensive evaluation of the patient’s condition and symptom severity.

Prevention Tips for GERD

• Eat smaller, more frequent meals

• Avoid eating 2–3 hours before bedtime

• Maintain a healthy weight

• Quit smoking

• Limit foods that trigger symptoms

When Should You See a Doctor?

Medical consultation is recommended when heartburn, chest pain, or difficulty swallowing persists or worsens over time.

In conclusion, Professor Dr. Nabil Dweidar confirms that GERD is a highly manageable condition when diagnosed early and treated properly. Following medical advice and adopting a healthy lifestyle significantly reduces symptoms and improves quality of life.
