Constipation after Surgery
Traffic Jam
Stephen King: "If one's bowels move, one is happy, and if they don't move, one is unhappy. That is all there is to it."
FROM THE TRENCHES
Here’s an actual post from a man on my Facebook support group:
I have a crappy question. And it's probably TMI. SORRY. Real problem.
I have something to help me sit on the toilet. I like it. I was told I could put the heel of my ankle on the ground once I sit. Okay.
But…
How the heck does one poop without putting weight on your ankle? I seem to do more harm than good on my NWB ankle when I'm on the toilet.
I twist my leg; I put pressure on it as I twist and... clean. I've even noticed I bear down on it when I “struggle."
I honestly think pooping is the most threatening behavior to my ankle.
If you’re having a similar issue, a raised toilet seat, toilet safety frame or grab bars, or a bedside commode can make managing hygiene and keeping your injured leg safe while non-weight-bearing. The injured leg may need to be supported or positioned out in front rather than tucked underneath you. Follow whatever weight-bearing instructions the surgeon or physical therapist gave you.
NOBODY TOLD ME...
Between the anesthesia, the pain killers, and the inactivity, you’re bound to get… well, bound. You definitely want to get in front of the situation.
Let’s be perfectly clear.
Start prevention early. If you're prescribed opioids, don't wait until you're constipated to think about a bowel regimen.
Traffic Jam
Constipation is a very common problem during recovery, especially after surgery. One of the biggest culprits is opioid pain medication, which slows digestion and makes it harder for the body to pass stool. Combined with reduced activity, changes in diet, and dehydration, constipation can quickly become uncomfortable. Fortunately, there are safe, effective ways to prevent and manage opioid-induced constipation after surgery.
Why Opioids Cause Constipation
How they affect the body:
Opioids (like oxycodone, hydrocodone, and morphine) relieve pain by acting on opioid receptors in the nervous system. But they also bind to opioid receptors in the digestive tract, slowing bowel contractions and causing harder, drier stools — known as opioid-induced constipation (OIC).
Benefits:
· Effective for controlling pain after surgery or fractures.
Allow patients to rest and heal.
Cautions:
Constipation can occur even with short-term opioid use.
May cause bloating, abdominal pain, and straining that interferes with healing.
MY TAKE ON IT
If I take even a couple of oxycodone, I’m going to be constipated. And none of us need more misery on top of the misery.
Increasing Fluids
How it helps:
Hydration softens stool and keeps the digestive system moving.
Benefits:
Simple, drug-free relief method.
Water, clear broths, and herbal teas are gentle on the system.
Cautions:
People with heart or kidney conditions may need medical guidance on fluid intake.
Dietary Fiber
How it helps:
Fiber adds bulk and softness to stool, making it easier to pass.
Benefits:
Found in fruits, vegetables, beans, and whole grains.
Fiber supplements like psyllium husk can help.
Cautions:
Increase slowly to avoid gas or bloating.
Works best alongside proper hydration.
If you're already significantly constipated from opioids, ask your healthcare provider before adding a bulk-forming fiber supplement such as psyllium.
Gentle Movement
How it helps:
Light walking stimulates digestion and promotes regular bowel movements.
Benefits:
Improves circulation and supports overall healing.
Even short walks can help prevent constipation.
Cautions:
Only move within the limits your doctor recommends.
Avoid activities that risk falls or strain.
Stool Softeners and Laxatives
How they help:
OTC stool softeners (like docusate sodium) and laxatives (like polyethylene glycol) are often recommended to offset opioid side effects. Docusate sodium doesn’t stimulate the bowel. Instead, it helps mix water and fats into the stool, making it softer and easier to pass. It works gently, usually within 12 to 72 hours after taking it. Polyethylene glycol also works without stimulating the bowel. It draws water into the stool, making it softer and easier to pass, and typically produces a bowel movement within one to three days.
Benefits:
Prevent constipation before it becomes severe.
Gentle and generally safe for short-term use.
Cautions:
· Use alongside appropriate hydration, diet and activity rather than relying on medication alone.
Stimulant Laxatives
How they help:
Stimulant laxatives, such as senna (Senokot) and bisacodyl (Dulcolax), work differently from stool softeners and osmotic laxatives. They stimulate the muscles of the intestines, helping move stool through the bowel. This can make them particularly useful for opioid-induced constipation, because opioids don't just make stool harder — they also slow the movement of the digestive tract. Stimulant laxatives generally work faster than stool softeners or polyethylene glycol, although timing depends on the product and how it is taken.
Benefits:
Help get the bowel moving when opioids have slowed intestinal activity.
May be useful when a stool softener or osmotic laxative alone isn't enough.
Available over the counter and generally intended for short-term use.
Cautions:
Can cause abdominal cramping, diarrhea or urgency.
Taking too much can lead to diarrhea, dehydration and electrolyte problems.
Don't simply keep increasing laxatives if constipation persists or you develop significant abdominal pain, vomiting, severe bloating or an inability to pass gas. Contact your healthcare provider.
WORTH KNOWING
Being drug sensitive, I went for the stool softener first, as it seemed like the least dramatic option. But several days in, after little change, I went for a small dose of bisacodyl, which did the trick in one night.
Listening to Your Body
How it helps:
Recognizing early signs — fewer bowel movements, harder stools, or abdominal discomfort — allows for quicker action.
Benefits:
Prevents constipation from worsening.
Encourages proactive self-care during recovery.
Cautions:
Severe constipation, abdominal pain, or vomiting requires urgent medical care.
ASK YOUR SURGEON
Constipation is extremely common after surgery, particularly if you're taking opioid pain medication. Before you leave the hospital or surgical center, ask what your surgeon recommends to prevent it rather than waiting until you're already uncomfortable. Here are some questions for your surgeon.
Should I start a stool softener or laxative while I'm taking opioid pain medication?
What do you recommend, and how often should I take it?
How long without a bowel movement is too long?
What should I do if the first-line treatment isn't working?
What symptoms mean I should call you or seek medical care?
