The unusual symptoms of Gastroesophageal Reflux Disease

Gastroesophageal reflux disease (GERD) is common. At least 20% of respondents in one survey reported heartburn weekly. Of this 10% have endoscopic evidence of esophagitis (inflamed esophagus from acid erosion) according to another estimate. It is estimated that GERD accounts for more than 1.8 million outpatient office visits a year in the USA. It accounts for nearly $10 billion in annual costs for diagnosis and treatment. It also undermines the quality of life more than arthritis, myocardial infarction, heart failure and hypertension.

It is common knowledge that GERD causes heartburn, frequent burping and belching, water brash, chest pain and swallowing difficulties. What is not known to most patients is that GERD could be associated with atypical symptoms and signs at times and could be missed easily if not actively lookedFor example, GERD could be related to recurrent sinus and ear infections, loss of enamel from teeth, frequent sore throats, hoarseness, laryngitis, chronic cough, asthma, vocal cord dysfunction and recurrent pneumonia from macro or microaspiration of stomach contents into lungs and scarring of lungsIt could cause swallowing difficulties, poor weight gain, and gross or occult loss of blood in the stool, vomiting of blood, anemia and cancer of the esophagus. GERD could be confused with a heart attack because of severe chest pain it causes at times.

Esophagus and lung bronchial tubes arise from a common passage that later splits into two separate passages in the human embryo. Both tubes also have common nerve supply from the brain- 10th cranial nerve called vagus nerve supplies both. Therefore, it is not surprising that acid irritation of the esophagus causes neurologically arbitrated reflex constriction of the bronchus and causes asthma and chronic cough. It is estimated that nearly 20% of people who cough for more than eight weeks do so because of GERD. A cough gets better once GERD gets treated. In one pediatric study, nearly 90% of children’s asthma got better significantly following diagnosis and treatment of GERD for one year with medications.

Asthma gets worse for several reasons during the night. Gastroesophageal reflux is one of them. GERD should be suspected in patients with asthma whose symptoms typically flare up suddenly during the night and who cough or choke during or following meals. Vocal cords are a pair of structures in our voice box (larynx) which help us speak and help guard our airways against entry of food and fluid during meals. With frequent exposure to acid in people with GERD, the vocal cords get inflamed. This commonly results in hoarseness of voice. It is not uncommon for patients who present with chronic or recurrent hoarseness of voice to deny that they have any symptoms of GERD. Often the hoarseness gets better with the satisfactory treatment of GERD.

Chronic irritation of vocal cords from acid exposure also makes the vocal cords more irritable. This results in paradoxical vocal cord spasm and sudden closure of airway resulting in sudden temporary loss of voice and difficulty breathing at times. This is known as Vocal Cord Dysfunction (VCD). The VCD should be suspected in patients with asthma whose asthma gets suddenly worse and is associated with laryngeal symptoms such as hoarseness and temporary and transient loss of voice. Proper diagnosis and treatment of GERD helps patients with VCD and asthma.

GERD should be suspected in children who fail to gain weight adequately and who vomit easily following crying or coughing. The weight loss occurs because of loss of calories from vomiting and reduced intake of food because of esophagitis. The gastroesophageal reflux is more common in infants who are born prematurely and during the first year of life. As the child assumes the more erect posture, starts eating more solid food and as the maturity of the valve that guards the lower end of esophagus improves, the reflux gets better. A word of caution is needed here, however. Rarely children presenting with symptoms resembling GERD may have a condition known as Eosinophilic Esophagitis. The cause of this condition is not known. Food allergy is suspected in some. This condition should be suspected in children who seemingly have GERD and who do not improve even after acceptable treatment of GERD. Endoscopy and biopsy are needed to prove the diagnosis.

If you or your loved ones have anyone of the conditions above, please consult with your doctor.
