Many people have experienced feelings of dry cough, itchy throat or choking after eating full. Many cases believe that it is a sign of sore throat, cold or respiratory infection and arbitrarily use cough medicine or anti-inflammatory drugs. However, according to experts, the real cause of this condition sometimes lies in the digestive system.
Dr. Joseph Salhab, a digestive expert in Florida (USA), said that chronic coughing after meals, prolonged hoarseness or feeling like something is stuck in the throat can be a manifestation of throat reflux, also known as LPR. This is a form of acid reflux, but different from common gastroesophageal reflux.
According to Dr. Salhab, LPR occurs when acid and pepsin enzymes from the stomach rebound to the esophagus and continue to the larynx.
The larynx is an extremely sensitive area. Just a small amount of acid or pepsin in contact is enough to cause irritation, leading to dry cough, sore throat or hoarseness," Mr. Salhab explained.
The point that makes many people easily confused is that LPR does not necessarily cause heartburn, which is a typical symptom of gastroesophageal reflux. Therefore, patients often do not think about digestive problems but focus on treating the throat or respiratory tract, causing the condition to last for a long time.
In addition to postpartum coughs, common signs of laryngeal reflux also include prolonged dry coughs, a feeling of sore throat, continuous hoarseness, morning or after-dish hoarseness. These symptoms are often more severe when eating full, eating late, or lying down immediately after eating.
Dr. Salhab said that LPR treatment is not only based on drugs but also needs to combine lifestyle and diet changes. The main goal is to reduce irritation and limit acid reflux from contact with the larynx. Foods that are easily irritable such as coffee, alcohol, spicy and hot foods, high-acid foods, chocolate and mint should be limited.
In addition, eating habits also play an important role. Avoiding overeating, not eating close to bedtime, and maintaining a low-acid diet can significantly reduce symptoms. In some cases, doctors may consider using products containing sodium alginate, creating a protective membrane on the surface of stomach acid, helping to limit upward reflux.
However, experts emphasize that if the cough after eating persists, does not improve, or becomes increasingly serious, patients should see a digestive or ear, nose and throat specialist for an accurate diagnosis.
Treating the cause correctly not only helps reduce uncomfortable symptoms but also prevents long-term effects on the larynx and quality of life.
