GERD, or Gastroesophageal reflux disease is a chronic disorder in which stomach acids flow backwards into the esophagus. For years the relationship between GERD and asthma has been discussed and studied extensively, and new research has shown the possibility that GERD can affect asthmatic conditions in some ways.

There are two possible ways in which GERD can affect asthma. One is that that the acid flow backward can cause damage to the linings of the lungs, throat and airways, trigging persistent cough by making breathing difficult. Another hypothesis is that, inhaling small amounts of stomach acid back into the lungs and the esophagus can trigger a nerve reflex to narrow the airways so that the acids cannot enter. This can cause shortness of breath, hence facilitating the development of asthma.

Although it has been seen that people with asthma are twice as likely to develop GERD as those who don’t, the exact relationship is still uncertain.

GERD may sometimes worsen symptoms of asthma, while at other times, treatment of GERD may alleviate symptoms of asthma.  If a person has both GERD and asthma, it is important for him to always follow prescribed medications, and control their exposure to stimulants that trigger asthma. Controlling and adjusting personal behaviors can also help in both conditions.
