Panic and shortness of breath in stomach discomfort may not necessarily be caused by stomach cancer, but also by cardiovascular diseases, which need to be treated after the cause is clear. Panic and shortness of breath in stomach discomfort are usually caused by the accumulation of most blood in the stomach in order to digest food during eating, which leads to insufficient blood supply to the heart muscle, resulting in symptoms such as chest tightness, panic and shortness of breath. If the symptoms are obvious, heart disease can be considered. In general, patients with gastric cancer have no obvious symptoms in the early stage, but in the middle and late stage, they may have discomfort symptoms such as nausea and vomiting with the progress of the disease, and some patients also have stomach discomfort symptoms such as stomach pain as the main manifestation. Therefore, shortness of breath with stomach discomfort is not necessarily a stomach disorder, but may be related to heart disease, and patients can also visit cardiovascular medicine to exclude cardiogenic factors.
