Mitral stenosis patients can consume donkey-hide gelatin, but the gelatin itself does not treat mitral stenosis. If there is mitral stenosis, especially severe stenosis, surgery should be undertaken as soon as possible.

Without surgical treatment, as time progresses, mitral stenosis can cause the left atrium to enlarge, leading to atrial fibrillation, arrhythmias, and symptoms of heart failure. Additionally, atrial fibrillation can easily lead to thrombotic complications, such as causing a cerebral infarction. Severe cerebral infarction can lead to hemiplegia, long-term bed rest, significantly impacting the patient's quality of life, and increasing economic burdens. Early surgery can effectively prevent these complications.
