Why do I experience bloating, belching, and discomfort after having a cardiac stent procedure, and what should I do about it?

Cardiac stent usually refers to cardiac stent implantation. Patients may experience stomach bloating, hiccups, and discomfort after the procedure due to factors such as the effects of anesthetic drugs, reduced physical activity, or improper diet. These symptoms can be improved through general management or medication. The detailed analysis is as follows:

1. Effects of Anesthetic Drugs

During cardiac stent implantation, anesthetic drugs are commonly used. These medications may affect normal gastrointestinal motility and gas expulsion, leading to stomach bloating. This is a normal phenomenon and symptoms typically resolve within two to three days.

2. Reduced Physical Activity

After cardiac stent implantation, patients are usually required to remain in bed for a period of time, resulting in decreased physical activity. This slows gastrointestinal motility and impairs gas release from the digestive tract, causing bloating. Under medical guidance, appropriate postoperative activity can help stimulate intestinal movement and relieve bloating.

3. Improper Diet

Poor dietary management after cardiac stent implantation—such as drinking excessive fluids or consuming hard-to-digest foods—can easily lead to stomach bloating and local discomfort. Under a doctor's supervision, patients may use prokinetic agents or digestive enzyme preparations, such as domperidone tablets or lactase tablets, to alleviate symptoms.

In addition to the above causes, conditions such as acute gastritis, gastric ulcers, or gastroesophageal reflux disease (GERD) could also be responsible. If symptoms are severe or persist, prompt medical consultation is recommended to receive professional evaluation and treatment.
