Poor lung function generally does not directly lead to adverse effects on kidney function. However, if the patient needs to take medication for a long period of time, or when there is complication of pulmonary heart disease or lung infection, etc., it may have certain impact on the kidney function. 1. Direct effect: Lungs and kidneys are two different systems, so under normal circumstances, poor lung function will bring adverse effects to the metabolic system, digestive system and nervous system and other organs and tissues, which may induce dizziness, tightness in the chest, fatigue, palpitations (heartbeat acceleration, often accompanied by panic), and poor breathing and other symptoms, but generally will not affect the kidneys. 2. Indirect effects: poor lung function, such as chronic obstructive pulmonary disease or asthma and other diseases exist, often need to receive long-term drug therapy, and these drugs generally need to be metabolized by the kidneys, and then may increase the burden on the kidneys; or combined with pulmonary heart disease patients, due to cardiac insufficiency, can also lead to adverse effects on kidney function. When lung function is not good or discomfort occurs, it is recommended that patients need to go to the regular hospital to receive examination, after a clear diagnosis, active treatment.
