This is quite possible, as the oesophagus is simply not made to deal with stomach acids and continuous exposure to these, could do long-term damage to the lining of the oesophagus. This can result in the narrowing or scarring of the oesophagus, which could make swallowing difficult. Long-standing GORD can also cause a condition called Barrett's oesophagus, which is thought to be a risk factor for oesophageal cancer. Damage to the teeth and vocal cords can also occur.
