Smoking
Smokers are often at a higher risk of having indigestion. Harmful substances in tobacco products would make the muscles between their stomach and esophagus relax. In the long run, this allows stomach acids to flow up into the esophagus from the stomach and affect the digestive system. Some chemicals in cigarettes might also cause damage to these muscles or directly trigger symptoms of indigestion. Therefore, you should stop smoking to improve symptoms and reduce the risks. [5]
