Dysphagia is a difficulty in swallowing drinks or food, felt in the throat or chest.
It is perceived as a sensation of discomfort, even blockage of solid or liquid foods during swallowing. Dysphagia is not a disease in itself, it is a symptom. It can be secondary to a neurological disease (stroke, head trauma, etc.), a muscular disease, or a mechanical attack. It can be located in the pharynx, in case of high dysphagia, or in the esophagus, in case of low dysphagia.
In any case, this symptom should not be overlooked, especially when it lasts. Because if dysphagia can reveal a mild illness, it may also reflect a more serious condition. In all cases, additional examinations should be carried out to establish a diagnosis. Whatever the latter, the consequences of dysphagia should not be neglected: malnutrition, dehydration and pulmonary infections. Complications all the more likely that dysphagia is important, and even more serious that the person is elderly.
This article reviews this symptom, whose causes are as numerous as the mechanisms of swallowing are complex.
In fact, according to the dysphagia symptoms of which the patient suffers, two types of dysphagia can be distinguished: high dysphagia and low dysphagia.
