Smoking and Hernia Why your surgeon asks you to quit before the operation
Cigarettes do not only harm the lungs; they weaken the abdominal wall and affect the success of hernia surgery and your recovery.
In this article
Patients are often surprised when their hernia surgeon asks them to stop smoking weeks before surgery. But this request is not a minor detail: smoking affects the tissues the repair is built on, wound healing, and the cough that strains the abdominal wall. Understanding this helps you make a decision that protects the result of your surgery in the long term.
How does smoking harm the abdominal wall?
Weaker collagen
Smoking affects collagen formation, which gives tissues and scars their strength.
Less blood supply
Nicotine narrows small vessels, reducing oxygen delivery to the wound.
Chronic cough
Smoker’s cough constantly raises abdominal pressure and strains the wall.
Weaker immunity
It increases the chance of wound infection after surgery.
For these reasons smoking is linked to a higher chance of developing a hernia — particularly an incisional hernia after surgery — and a higher chance of recurrence after repair.
Smoking and complications of hernia surgery
| Complication | Effect of smoking |
|---|---|
| Wound infection | More likely because of poor blood supply and immunity |
| Delayed wound healing | Slower and weaker healing |
| Breathing problems after anaesthesia | More phlegm, cough and breathlessness |
| Hernia recurrence | Weaker tissues and repeated pressure from coughing |
| Mesh problems | Infection around the mesh is more likely with smoking |
For abdominal wall reconstruction and giant hernias, the surgeon may require complete cessation before scheduling surgery, because smoking has a bigger effect on the result.
When should you stop smoking?
The earlier you quit the better; the benefits begin within days and increase with time:
Weeks before surgery
Stopping several weeks before surgery is usually advised so that blood supply and lung function start to improve.
The day of surgery
No smoking at all before anaesthesia, as instructed by the anaesthetist.
After surgery
Stay smoke-free at least throughout healing — ideally for good.
Support
Use stop-smoking programmes and nicotine replacement as advised by your doctor.
Practical tips for quitting
- Set a clear quit date and link it to your surgery date as motivation.
- Get rid of cigarettes and lighters and avoid smoking places.
- Ask your doctor about nicotine replacement or supportive medication.
- Replace the smoking habit with walking or breathing exercises.
- Ask family and friends for support.
Misconceptions
- “Cutting down is enough.”
- “E-cigarettes are completely safe before surgery.”
- “Stopping the day before surgery is enough.”
The truth
- Quitting completely is much better than cutting down.
- Nicotine in any form affects blood vessels and healing.
- Real benefit needs weeks of stopping.
“Quitting smoking before hernia surgery is part of the treatment itself, not just general health advice.”
Dr. Mohamed EsmatConsultant hernia & abdominal wall surgeonFrequently asked questions
Can a smoker have hernia surgery?
Yes in many cases, but quitting beforehand clearly reduces complications, and the surgeon may require it in complex cases.
Is shisha (water pipe) like cigarettes?
Yes, shisha carries the same risks and sometimes more; the same advice applies.
Do nicotine patches affect healing?
Nicotine itself affects blood vessels, so replacements are used as the doctor judges and for a limited period.
