Most often, discomfort in the gastrointestinal tract is provoked by an unhealthy diet.
Every person has experienced this unpleasant state at least once in their life. Sometimes heartburn is a relatively harmless condition that occurs after eating junk food or overeating.  But sometimes, it may turn out to be a symptom of serious diseases that should be treated urgently.
If heartburn becomes regular, it is worth seeing a doctor for an examination. However, more often than not, in order to get rid of unpleasant sensations, it is enough to adjust your diet.
There are many reasons for the development of heartburn.  Most often it is provoked by improper diet – certain foods that the body cannot absorb without side effects. If you do not know what foods can provoke discomfort and how the process of digesting food occurs, heartburn can torment you constantly.
The stomach is separated from the esophagus by a muscle ring called the sphincter. This muscle ring opens to allow food to enter the stomach, and closes tightly to prevent acidic gastric juice from entering the esophagus.
When working properly, the sphincter should always be tightly closed.  But sometimes his work fails and he weakens. Then the gastric juice splashes out and burns the esophageal mucosa. This is how heartburn occurs.
If the gastric juice burns the lining of the esophagus too often, scars will form on it. They can cause a variety of diseases of the gastrointestinal tract, or even esophageal cancer in extreme cases.
