Research shows that colorectal cancer patients who walk more than 3,781 steps in the first two days after surgery are 6 times more likely to be ready to leave the hospital by day three, according to a 2026 pilot study of 38 patients. Gram Research analysis found that patients in the active group went home about one day earlier on average and had better early diet recovery compared to those who walked less.
A new study from 2026 shows that patients who walk more in the first two days after colorectal cancer surgery recover faster and go home sooner. Researchers tracked 38 patients using smartwatches to count their steps after surgery. Those who took more than 3,781 steps in the first two days were much more likely to be ready to leave the hospital by day three, compared to patients who walked less. According to Gram Research analysis, this suggests that encouraging patients to move around early after surgery could be a simple way to speed up recovery and reduce hospital stays.
Key Statistics
A 2026 pilot study of 38 colorectal cancer surgery patients found that those who took more than 3,781 steps in the first two postoperative days were 6.07 times more likely to achieve discharge readiness by day 3 compared to less active patients.
According to research reviewed by Gram, patients who walked more after colorectal cancer surgery had a median hospital stay of 5 days versus 6 days for less active patients, representing a one-day reduction in postoperative length of stay.
A 2026 study published in Annals of Coloproctology found that 68.4% of highly mobile patients met discharge criteria by postoperative day 3, compared to only 26.3% of less mobile patients undergoing colorectal cancer surgery.
The Quick Take
- What they studied: Whether the number of steps patients take in the first two days after colorectal cancer surgery can predict how quickly they recover and are ready to go home.
- Who participated: 38 adults who had elective colorectal cancer surgery at a major hospital between August 2023 and December 2024. All wore smartwatches to track their daily steps.
- Key finding: Patients who walked more than 3,781 steps in the first two days after surgery were 6 times more likely to be ready for discharge by day three, compared to those who walked less. They also went home about one day earlier on average.
- What it means for you: If you or a loved one is having colorectal cancer surgery, getting up and walking around early in recovery may help you heal faster and spend less time in the hospital. Talk to your surgical team about safe ways to increase movement after your procedure.
The Research Details
This was a prospective pilot study, which means researchers followed patients forward in time from the day of surgery and collected information as events happened. Patients undergoing elective colorectal cancer surgery at a single academic hospital wore a Galaxy Watch 5 smartwatch starting on the day of their operation. The watch automatically tracked and recorded the number of steps patients took each day. Researchers recorded cumulative step counts on postoperative days 1 and 2 (the first and second days after surgery). Each day, doctors assessed whether patients met specific recovery milestones based on ERAS criteria, a standardized set of discharge readiness guidelines used after colorectal surgery. Patients were then divided into two groups based on whether their step count was above or below the median of 3,781 steps. The study compared how quickly each group achieved discharge readiness and how long they stayed in the hospital.
This research approach is important because it uses objective, real-time data from wearable devices rather than relying on doctors’ subjective observations or patient recall. Smartwatches provide continuous, accurate measurements of physical activity without requiring extra effort from patients or staff. By connecting this objective mobility data to established discharge criteria, the study creates a measurable target for recovery that could help doctors and patients understand what level of activity supports faster healing.
This is a pilot study with a small sample size of 38 patients at a single hospital, which means the results are preliminary and need confirmation in larger studies. However, the study used objective wearable technology rather than subjective measures, which strengthens the reliability of the activity data. The use of predefined ERAS discharge criteria provides a standardized, validated measure of recovery readiness. The prospective design (following patients forward in time) is stronger than retrospective studies that look backward at medical records. The statistical findings showed clear differences between groups with a P-value of 0.009, indicating the results are unlikely due to chance alone.
What the Results Show
Among the 38 patients studied, those in the active group (who walked more than 3,781 steps in the first two days) achieved discharge readiness by postoperative day 3 in 68.4% of cases, compared to only 26.3% in the less active group. This represents a 6-fold increase in the odds of being ready to go home by day three. The active group also reached discharge readiness earlier, with a median time of day 3 compared to day 4 for the less active group. The difference in hospital stay length was also significant: the active group had a median stay of 5 days versus 6 days for the less active group. These differences were statistically significant, meaning they are unlikely to have occurred by chance. Early diet tolerance, an important marker of digestive recovery, also differed between groups, with the active group tolerating food better earlier in their recovery.
The study found that early postoperative step counts correlated with multiple aspects of recovery beyond just discharge timing. Patients who walked more showed better early diet tolerance, suggesting their digestive systems recovered more quickly. The shorter overall hospital stay in the active group (5 days versus 6 days) represents a meaningful reduction in healthcare costs and time away from home. The consistency of findings across multiple recovery measures (discharge readiness, time to readiness, length of stay, and diet tolerance) suggests that early mobility has broad benefits for postoperative recovery.
This research builds on existing knowledge that early mobilization is a key part of Enhanced Recovery After Surgery (ERAS) pathways for colorectal cancer patients. However, previous studies have relied mainly on subjective assessments or patient-reported activity levels. This study is among the first to use objective wearable device data to quantify early postoperative mobility and link it to specific recovery outcomes. The findings support the theoretical basis for ERAS protocols while providing concrete, measurable targets for the amount of activity that appears beneficial. The results align with broader surgical literature suggesting that early movement after surgery improves outcomes.
This is a pilot study with only 38 patients from a single hospital, so results may not apply to all patients or all hospitals. The study used a specific smartwatch model and may not reflect results with other activity trackers. The median step count of 3,781 steps was used to divide patients into groups, but this cutoff may not be the optimal target for all patients or may differ based on age, fitness level, or type of surgery. The study did not track whether patients had complications or other factors that might have limited their ability to walk. Because this is a pilot study, larger studies are needed to confirm these findings before they can be widely applied to clinical practice.
The Bottom Line
Based on this research, patients undergoing colorectal cancer surgery should aim to increase their walking and movement as tolerated in the first two days after surgery, with a target of around 3,781 steps or more if possible. This recommendation comes with moderate confidence because the study is small and preliminary, but it aligns with established ERAS principles. Patients should work with their surgical team to determine what level of activity is safe for their individual situation, as some patients may have complications or other conditions that limit mobility. Healthcare providers should consider using wearable devices to track and encourage early postoperative mobility as part of standard recovery protocols.
This research is most relevant to adults undergoing elective colorectal cancer surgery who want to optimize their recovery. Surgeons and surgical teams should consider these findings when counseling patients about postoperative activity. Patients with significant mobility limitations, severe complications, or other medical conditions should discuss activity goals with their doctors before surgery. This research may also interest healthcare systems looking to reduce hospital stays and improve recovery outcomes. People recovering from other types of abdominal surgery may benefit from similar principles, though this study specifically examined colorectal cancer surgery.
Based on this study, patients who achieve higher step counts in the first two days after surgery may be ready for discharge by postoperative day 3, compared to day 4 or later for less active patients. However, individual recovery timelines vary. Most patients in the active group went home around day 5, while less active patients stayed about 6 days. Realistic expectations are that increased early mobility may shorten your hospital stay by one day on average, though some patients may see greater or lesser benefits depending on their individual circumstances and any complications.
Frequently Asked Questions
How much should I walk after colorectal cancer surgery to recover faster?
Aim for around 3,781 steps in the first two days after surgery if medically safe, according to a 2026 study. Start small on day 1 and gradually increase. Always follow your surgeon’s specific instructions, as individual recovery varies based on complications and overall health.
Can walking after surgery really help me go home sooner?
Yes. Research shows patients who walked more in the first two days after colorectal cancer surgery went home about one day earlier on average and were 6 times more likely to be ready for discharge by day 3 compared to less active patients.
What is ERAS and why does it matter for my surgery recovery?
ERAS stands for Enhanced Recovery After Surgery. It is a set of evidence-based practices designed to help patients recover faster after surgery. Early mobilization, or getting up and walking soon after surgery, is a key part of ERAS protocols for colorectal cancer patients.
Is it safe to walk around right after colorectal cancer surgery?
Early walking is generally safe and encouraged after colorectal cancer surgery as part of standard recovery protocols. However, you should always follow your surgeon’s specific guidance about when and how much to walk based on your individual situation and any complications.
How can I track my activity after surgery to monitor my recovery?
Use a smartwatch or wearable fitness tracker to count your daily steps starting the day after surgery. Share this data with your surgical team to demonstrate your recovery progress and discuss whether you are meeting discharge readiness milestones.
