The bloating can be treated by stopping or changing the medication, taking oral medication, or using intravenous medication. 1. Stop or change drugs: bloating after taking drugs may be a side effect of the drugs, or the drugs may stimulate the gastric mucosa leading to gastritis. You can stop taking the medication temporarily or change to other medications with less side effects. 2. Oral medication: taking medication for bloating can take domperidone, mosapride and other drugs to promote gastrointestinal peristalsis, but may lead to diarrhea, allergies, dizziness and other side effects. 3. Intravenous drug treatment: When taking medicine for bloating, if oral medicine is not effective, you can use intravenous metoclopramide, vitamin B6 and other drugs to promote gastrointestinal peristalsis and relieve the symptoms of bloating. All of the above drugs should be used under the guidance of a doctor, and self-medication is not recommended. You can also check the abdominal ultrasound, gastroscopy and other items first, to clarify the cause of treatment under the guidance of the doctor.
