When patent ductus arteriosus (PDA) progresses to a certain extent, it can affect appetite.

If the patent ductus arteriosus causes pulmonary arterial hypertension, leading to right heart failure, it results in congestion of the gastrointestinal tract and the liver. This significantly impacts the digestive and absorption functions of the gastrointestinal tract, causing reduced appetite in the patient. Some patients may also experience nausea, vomiting, and abdominal distension.

For patients with patent ductus arteriosus, if there are indications for surgery, timely surgical treatment should be carried out to correct the anatomical abnormalities and prevent the progressive worsening of the patent ductus arteriosus, which could lead to adverse outcomes.
