Hey there, hello,
When you eat, a muscular ring between the end of the esophagus and the entrance to the stomach -- called the lower esophageal sphincter (LES) -- relaxes to let food in. Once it has closed again, the stomach releases acids and enzymes to break down the food.
Usually, these acids stay put in the stomach. But in people with GERD, the sphincter may stay relaxed or relax at the wrong time. This allows stomach contents containing acids and enzymes to wash back up, irritating the tissue of the esophagus.
Experts believe tobacco might worsen heartburn in a number of ways, including impairing the function of the LES, and increasing acidity.
I am sure you will be hearing from other members.
