Hello, If the stent procedure was performed through radial or brachial artery (which is the usual case), pain lower abdomen and gas do not co relate with the procedure; against the femoral approach which is much concerned. My guidelines at present: - Do regular aerobics (after discussion with your cardiologist) to control the belly fat - High fiber diet - Bulk forming laxatives manage soft, regular stool evacuation without failure - Avoid spices, non-veg, junk items, dairy fat - Avoid weight lifting (if involved) - Control of blood sugar, cholesterol, body weight An ultrasound or other relevant investigation are needed as per the requirement ahead in clinical scene. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Bhagyesh V. Patel, General Surgeon
