How soon can you start exercising after umbilical hernia repair?

Depends: Was it done open? Lap? With mesh? What was the size of hernia? What is your bmi?Medical condition? The type of exercise you have in mind? Your surgeon is the person best suitable for answering this question.

Depends: It really depends on the size, use of mesh, surgical technique, surgeon preference and patient factors (diabetes, smoking, obesity, steroids, etc). Most people heal completely in 6 weeks. Some surgeons give no restrictions, others recommend waiting 2-3 weeks, and other surgeons want 6-8 weeks. The best thing to do is follow what your surgeon recommended.

Mesh or not: Usually 4-6 weeks. And the key component is as toletated. Meaning dont overdo it when you first start to exercise.

About 4 weeks: Exercising too soon can cause the hernia to recur. The surgeon will recommend that you avoid exercise for longer if the hernia is large and if the surgery is done open (with a single larger incision). The surgeon will probably say that you can climb stairs right away, lift 15 lbs at ~2 weeks, light exercise at ~3 weeks, and strenuous exercise at 4-6 weeks.
