Pulmonary regurgitation usually does not heal on its own. Once a patient develops pulmonary regurgitation, he or she must pay great attention to it and undergo timely examination to determine the cause of pulmonary regurgitation, which is usually closely related to pulmonary hypertension. Generally, pulmonary hypertension is caused by lung diseases, such as lung infection, chronic bronchitis, emphysema, etc. When patients develop pulmonary hypertension and pulmonary regurgitation, they must actively treat the primary disease, such as anti-inflammatory or bronchodilator treatment, to delay the aggravation of the disease, and early and timely detection and treatment of the primary disease is beneficial to the treatment and recovery of the whole disease. Patients with pulmonary hypertension or pulmonary regurgitation should pay attention to their diet, prohibit smoking and alcohol consumption during the treatment period, and avoid eating spicy and cold foods, as stimulating foods will aggravate the burden of the organism, which is not conducive to the recovery and treatment of the whole disease.
