Recovering from colon surgery is not just about healing the incision– people only see the cuts on the skin, but there’s a lot of healing that is happening on the inside! You most likely have a new connection in your colon called an anastomosis. This connection can be fragile at first. Your digestive system needs time to adjust to this change, but your entire body may also feel like you just ran a marathon because of the anesthesia stress on your heart and lungs. After a colon resection, you may feel tired for a few weeks, and your bowel habits may change. The right diet and post-op protocol can make recovery smoother.
Clear liquids first: Most patients start with clear liquids (broth, gelatin, tea) as the bowel “wakes up.” Anything you can see through is allowed. Start slow but you do eventually want to maintain your hydration orally, and not be depending on an I.V.
Slow advancement: Your doctor will gradually advance your diet to soft, easy-to-digest foods. These softer foods will be less likely to harm that new connection in your colon. No steak or raw kale immediately post-op, please!
Low-fiber diet: In the first few weeks, foods low in roughage are easier to tolerate. Think BRAT diet: bananas, rice, applesauce, toast. Chicken, eggs, and yogurt are also great options.
Small, frequent meals: Eating smaller portions throughout the day reduces strain on the healing bowel.
Stay hydrated: Adequate fluids prevent dehydration and constipation.
Gradual reintroduction of fiber: Once cleared by your surgeon, start adding fruits, vegetables, and whole grains slowly to avoid gas and bloating. But you do want to have a high fiber diet to prevent future colon issues, like diverticular disease or constipation.
Limit irritating foods: Greasy, spicy, or very fibrous foods may cause diarrhea or cramping at first.
Protein for healing: Lean meats, fish, eggs, and dairy help repair tissues.
Early mobility is a huge part of a successful post-operative recovery. Even if you’re groggy, or in pain, or just plan don’t want to, returning to walking (ambulating) and your normal activities helps your gut return to normal sooner. I barely remember this, but my wife says that immediately after my appendectomy, I dragged my IV pole into the hallway and walked up and down with her as many time as I could. So while not necessarily about diet, walking after surgery will help recovery.
Your diet after a colon resection is all about gentle progression—starting with liquids, moving to soft foods, and slowly reintroducing fiber. This blog isn’t medical advice, just general information from Your Friendly Neighborhood Colorectal Surgeon. Please check with your doctor before resuming regular food. Everyone’s recovery is different, so follow your surgeon’s guidance and listen to your body. You may be starving after surgery and want a hundred cheeseburgers. But remember, everything in moderation, including moderation!
