A new study found that preparing your body for surgery with a diet and exercise regime can reduce complications and support recovery

Recovering From Surgery Is Hard. 'Prehabilitation' Could Make it Easier Here's why you should do "prehabilitation" before your next procedure

  • Exercising, eating a healthy diet, and having social support in the weeks before a surgery can reduce the risk of complications and boost recovery, a new study found.
  • These strategies are known as “prehabilitation,” or preparing your body for surgery at least a week in advance with an exercise and diet regimen.
  • Experts recommended talking to your doctor to create a prehabilitation plan specific for the procedure and your body.

Rehabilitation is a big focus after surgery, but new research suggests that you can improve your odds of having an easier recovery by making changes before going under the knife. This tactic is called “prehabilitation,” and a recent study suggests it can make a big difference.

“With this information, we can now move forward in helping patients to know what strategies may be best for them to prepare for surgery, and for researchers what key areas need to be the focus of new studies,” lead study author Daniel McIsaac, MD, anesthesiologist, professor, and vice chair of Research & Innovation at the University of Ottawa, told Health.

While prehabilitation is a term that has swirled around medical circles for years, it’s not well-known to the general public. Here’s what you need to know.

What Is Prehabilitation, Exactly?

Prehabilitation is a strategy used to help people prepare for a major surgery, Michael Sutherland, MD, a general surgeon and senior vice president of member services for the American College of Surgeons, told Health.

"It's very effective in circumstances when the procedure is scheduled at least one week in advance so that you have a little bit of time to take advantage of strategies that help prepare the body for the stress of surgery," Sutherland said.

Prehabilitation is all about being proactive, not reactive, said Chelsia Gillis, PhD, researcher, assistant professor, and director of perioperative research at McGill University. “We have adopted a view that recovery begins before the surgical incision,” she told Health.

Gillis said the term is “widely accepted” in medicine, although it’s not necessarily widely used.  

What Did the Study Find?

For the study, which was published in The BMJ, researchers analyzed data from 186 clinical trials on the prehabilitation methods of nearly 15,700 patients.

The researchers found that people who exercised regularly before their surgery had a 50% lower risk of complications than non-exercisers, while those who followed a healthy diet had a 38% lower risk than those who didn’t. Patients who focused on a combination of diet, exercise, and social support had a 36% lower risk of complications.

People who did a mix of exercise and social support spent two fewer days in the hospital. Meanwhile, those who did diet and exercise prehabilitation had their hospital stay cut by more than a day.

According to researchers, a key limitation of the study is that many of the studies used focused on one hospital. As a result, it’s not clear how well the findings would translate to other settings.

Still, the findings are promising for prehabilitation. “Our review found that prehabilitation based on exercise, nutrition, and especially exercise combined with other approaches were the most promising types of prehabilitation,” McIsaac said.

These findings aren’t entirely surprising, McIsaac noted. “The idea that exercise, nutrition, and psychosocial support would lead to better outcomes after surgery is, on one hand, common sense,” he said. “Across almost all areas of healthcare, being more physically fit, having good nutrition, and feeling mentally well lead to better patient outcomes.”

Building on the Research

Though the paper didn’t break down the results by patient age or surgery type, previous studies have focused on these more narrow topics.

A 2023 scientific review, for example, looked at 48 trials examining prehabilitation before orthopedic procedures. It found that of more than 3,500 patients, prehabilitation “significantly improved” function, quality of life, muscle strength, and back pain in patients compared to those who didn’t prep for the surgery. 

In one 2023 randomized clinical trial, researchers analyzed 251 adults with colorectal cancer who underwent surgery. They concluded that experiencing a four-week prehabilitation program led to a “significant reduction” of severe complications. Patients who did prehabilitation also recovered faster and better. 

But a 2024 study that looked solely at outcomes for older adults suggests that prehabilitation may not be as effective. Researchers had patients with a high risk of frailty or malnutrition who were scheduled for surgery undergo at least four weeks of prehabilitation two to three times a week before their operation.

They found that prehabilitation improved the patients’ exercise capacity, mobility, and nutrition but that improvements in muscle strength, cognitive function, and emotional resilience were “minimal.”

What Does a Healthy Prehabilitation Routine Look Like?

The best prehabilitation routine is one that’s tailored to your needs, Tracey Childs, MD, chief of surgery at Providence Saint John’s Health Center in Santa Monica, California, told Health.

“Patients should check with their surgeon as well as their medical specialists and request advice for preparing for surgery,” she said. “The sooner one starts getting ready for surgery, the more effective the prehabilitation will be.”

A healthy prehabilitation routine may include adjusting your diet to focus on specific foods or macronutrients as recommended by your doctor, Sutherland said. Your healthcare team may also recommend an exercise program.

“This doesn’t mean starting an intense new training regimen; It simply can involve aerobic activity, going on regular walks the week before the procedure, strength training, and some resistance work,” he said. “All of these things can be done at home and can be modified to account for whatever surgery you’re having done.”

In general, McIsaac said a “typical” program usually lasts for four to five weeks before surgery.

If you’re already healthy, McGillis suggests checking in with your healthcare team to make sure your definition of “healthy” checks out with what your doctor has in mind. They may have specific recommendations that are different from what you’re already doing.
