Inguinal Hernia Surgery

Yes!
No coughing! It transmits a very high amount of pressure onto your hernia repair.
Make sure you take whatever steps are necessary to stop the cough: cough drops, inhalers, antibiotics, cough syrup, etc. Talk to your medical doctor to stop the cough.
When coughing, first engage your abdominal muscles (tuck in your belly), then cough. That will help reduce the pressure transmitted to the hernia.
It is not 100% that it will undo your repair, and in fact we do not know what % risk there is with coughing, but it is among the most common causes for hernia recurrence. Others include chronic constipation requiring straining to have a bowel movement, large prostate requiring straining to urinate, and nicotine use.
