Why are women who have had hysterectomies restricted from lifting?

I did some preliminary research on Google scholar and based on the abstracts (the research was paywalled) of a couple of studies and one metanalysis done in 2013, I found that there seems to be no conclusive research on the effects of post-operative activity on hysterectomy patients. The actual restrictions (weight limits and length of restriction) seem to vary greatly from patient to patient. There must be a reason for them (increased risk of hernia? increased risk of adhesions?) What are the mechanics behind these?  I did find a website (can't confirm the reliability) for kidney donors which mentions a lifting restriction because of risk of incisional hernia.

In the sense of recovery after abdominal surgery, general recommendations for hysterectomy won't differ substantially from any other form of abdominal surgery.

Generally, recovery needs to be long enough to let a significant portion of healing of the abdominal wall occur.  Typical recommendations for this length of time are 6 weeks.  You're correct in that the risks are related to incisional complications such as hernia or dehisence.  Adhesions are an unavoidable part of the healing process for any intraabdominal procedure.

Based on your questioning, it sounds like you're asking about your own recovery or for someone you know.  In that case, the correct answer is: talk to your doctor.  They can and should be able to inform you about appropriate procedures for recovery postoperatively.    There's no reason a patient post-hysterectomy should not be able to begin weight training after appropriate recovery.
