What are the complications resulting from Acid Reflux? 

The most common complication of acid reflux is the formation of ulcers in the food pipe. In simple words, an ulcer is a break in the lining of the esophagus. Ulcers form when the acid attacks the cells of the food pipe. Sometimes when the damage is very severe, the ulcers can also cause bleeding in the food pipe. When the ulcers heal it causes the tissue to scar. When there are repeated episodes of Acid Reflux and ulcer formation, the scar tissues can cause the inner cavity of the esophagus to become so narrow that food cannot pass through it. 

Too many episodes of Acid Reflux can damage the esophagus tissue so badly that the cells then become cancerous. This condition is called Barret's Esophagus and it occurs in about 10 percent of Acid Reflux patients. It can also give rise to unexplained coughing. The theory goes that the regurgitated fluid in the throat can stimulate nerve ends going into the lungs causing the breathing tubes to narrow and result in coughing or asthma. In the same way the refluxed liquid can also cause a sore throat, cause inflammation of the sinues and even lead to discomfort in the ears. That is why it is so important to treat and cure episodes of Acid Reflux as soon as possible.
