There are people who suffer acid reflux when their stress levels are high.
Does Stress Really Make It Worse?
It’s still debatable whether or not stress actually increases the production of stomach acid or physically creates a worsening in acid. Currently, many scientists believe that when you’re
stressed, you become more sensitive to smaller amounts of acid in the esophagus. In other words, though the study participants reported feeling more discomfort, the scientists didn’t find any increase in total acid produced.
In another study published in 2005, researchers measured the levels of esophageal
acids in more than 40 patients who had chronic heartburn or acid reflux. They found that those who were stressed when required to prepare and deliver a five-minute speech reported more intense reflux symptoms. However, they actually produced no more acid than the patients who weren’t stressed.

We all know that stress can cause the body to change how we feel. There are two types of stress, good stress and bad stress. It is how we manage the bad stress that makes the difference.
