Complications

Dental Problems

Dental erosion (the loss of the tooth's enamel coating) is a very common problem among GERD patients, including children. It results from the acid backing up into the mouth and eroding the enamel.

Chronic Throat Conditions

An estimated 20% to 60% of patients with GERD have atypical symptoms in the throat (hoarseness, sore throat) without any significant heartburn. A failure to diagnose and treat GERD may lead to persistent throat conditions such as chronic laryngitis, hoarseness, difficulty in speaking, sore throat, cough, constant throat clearing, and granulomas (soft, pink bumps) on the vocal cords.

Sleep Apnea

GERD commonly occurs with obstructive sleep apnea, a condition in which breathing stops temporarily but repeatedly during sleep. It is not clear which condition is responsible for the other, but GERD is particularly severe when both conditions occur together. One study reported that spasms in the vocal cords caused by acid reflux may block the flow of air and cause sleep apnea in adults. On the other hand, other research suggests that the disordered breathing in sleep apnea alters pressure in the chest area and causes GERD. Both conditions may also have risk factors in common, such as sleeping on the back. Studies suggest that in such patients GERD can be markedly improved with CPAP, a device that opens the airways and is the standard treatment for severe sleep apnea.
