Diverticulitis changes how your poop looks. You might see blood-streaked stools, mucus, and alternating pellet-like poop and diarrhea. The color can turn bright red, maroon, or black. The shape often becomes thin like a pencil or small like rabbit pellets. Sometimes you get very hard poop, and other times it comes out watery.
This guide helps you understand what happens to your poop when you have diverticulitis. We’ll explain the different colors, shapes, and textures you might see. You’ll learn which changes need a doctor right away and which ones are less scary. We’ll also cover what foods help your gut heal and when your poop should get back to normal.
What Is Diverticulitis and How Does It Affect Your Gut?
Think of your colon like a garden hose. Small balloon-like pouches called diverticula can form where weak spots develop in the hose wall. These pouches are super common. About 35% of adults younger than 50 have these pouches, and up to 58% of people over 60 have them. But here’s the good news – only about 4% of people with these pouches ever get diverticulitis.
When food or poop gets stuck in these pouches, bacteria start to grow. This causes infection and swelling, which we call diverticulitis. Your whole gut system goes haywire when this happens. The infected pouches make your colon swell up inside, changing how waste moves through your body.
The swelling and infection mess with your colon’s normal job. The inflamed areas throw your colon’s normal rhythm completely off track. Instead of smooth muscle movements that push poop along nicely, you get crazy, uneven squeezing. This is why your bathroom trips become so unpredictable.
Why Your Location Matters
Where you live affects how diverticulitis shows up in your body. In North America and Europe, the pain usually hits the left lower side of your belly. But if you’re of Asian descent, the pain often shows up on the right side. This happens because people from different parts of the world develop pouches in different parts of their colon.
Normal Poop vs. Diverticulitis Poop: Spot the Difference
Before we dive into sick poop, let’s talk about what healthy poop looks like. Normal poop should be:
- Color: Medium to dark brown (like chocolate)
- Shape: Long and sausage-like, matching your colon’s shape
- Texture: Somewhere between soft and firm
- Smell: Strong but not super gross
- How often: At least three times a week, up to twice a day
When diverticulitis hits, everything changes. Your stool may be bright red, maroon, or black and tarry, which means there’s blood. Stools may have more mucus than normal. The texture goes wild too – you might alternate between very hard stools from constipation and loose, watery diarrhea.
Blood in Your Poop: What Different Colors Mean
Finding blood in your poop is scary, but understanding what it means can help you stay calm and get the right help.
Bright Red Blood
Bright red blood means the bleeding is happening close to where the poop comes out. The blood looks fresh because it hasn’t had time to change color. You might see red streaks on your poop or red water in the toilet. This usually means the infected pouches in the lower part of your colon are bleeding.
Black and Tarry Stools
Black or tarry stools happen when bleeding occurs higher up in your intestinal tract. The blood has time to get digested as it moves down, turning it dark and sticky like road tar. This type looks scarier but doesn’t always mean worse problems – it just tells you where the bleeding started.
Maroon or Dark Red
Maroon poop sits between bright red and black. This color often means bleeding is happening somewhere in the middle of your colon. The blood had some time to change but not enough to turn completely black.
Shape Changes: Why Your Poop Looks Different
The shape of your poop tells a story about what’s happening inside your colon.
Pencil-Thin Stools
When your colon gets swollen from diverticulitis, it can make the space inside smaller. This squeezes your poop as it comes out, making it thin like a pencil. Imagine trying to squeeze toothpaste through a straw instead of the regular opening – that’s what happens to your poop.
Pellet or Rabbit Droppings
Some people pass small, hard pieces that look like rabbit pellets. This happens when poop moves too slowly through your swollen colon. During the constipation phases, poop gets compressed into hard pellets because it moves too slowly through the inflamed colon.
Irregular and Weird Shapes
Inconsistent shapes and sizes can result from spasms in the colon or irregular stool movement through the digestive tract. Your poop might come out in strange shapes or different sizes each time because your colon muscles aren’t working right.
Texture Problems: From Rock-Hard to Watery
Diverticulitis makes your poop texture go from one extreme to another.
Hard as Rocks
When you’re constipated from diverticulitis, your poop becomes super hard and painful to pass. The swelling slows everything down, giving your colon too much time to suck water out of the poop. You might sit on the toilet straining and nothing comes out, or just tiny hard balls.
Loose and Watery
When diarrhea strikes, your irritated colon essentially hits the panic button and rushes everything through before proper water absorption can happen. You might need to run to the bathroom many times a day. The poop comes out like brown water, and you can’t control when you need to go.
The Mucus Problem
When your colon is inflamed, your body cranks up mucus production to protect and soothe the irritated colon lining. Your poop might look shiny, slimy, or covered in clear jelly-like stuff. While gross to look at, this mucus actually shows your body is trying to protect itself.
Warning Signs: When to Get Help Fast
Some poop changes mean you need a doctor right away. Don’t wait if you see:
Emergency Signs
- Lots of bright red blood in the toilet
- Black, tarry stools that smell really bad
- Can’t poop at all for several days
- Poop coming out when you’re not on the toilet
Other Danger Signals
You should seek emergency medical attention if you have blood in stool, excessive vomiting or severe nausea, fever over 100.4°F, or sudden and severe belly or back pain that gets worse quickly.
Remember, diverticulitis can cause abnormal stool function along with pain and fever. If your belly hurts really bad and your poop looks weird, don’t tough it out – get checked.
How Doctors Check Your Poop
When you see a doctor about poop problems, they have several ways to figure out what’s wrong.
The Poop Test
A provider collects a sample of your poop to test in a lab. A stool test may show signs of infection or gastrointestinal bleeding. You’ll poop in a special container, and the lab checks for blood you can’t see, bacteria, and signs of swelling.
Looking Inside Your Colon
Your doctor will use a thin, flexible tube with a light and camera to examine your colon for ulcers, polyps, bleeding or inflamed diverticula. They usually wait until you feel better to do this test because it’s too risky during a bad flare-up.
CT Scans
A CT scan creates a detailed image of your organs and can be used to look for infected diverticula or abscesses. This test helps doctors see how bad the infection is and if you have any serious problems that need quick treatment.
Foods That Change Your Poop During Flare-Ups
What you eat makes a huge difference in how your poop looks and feels during diverticulitis.
During a Bad Flare-Up
When diverticulitis is really bad, doctors often suggest starting with clear liquids only. This gives your gut a break. You can have:
- Clear broth (chicken or beef)
- Apple juice without pulp
- Jell-O (not red – it can look like blood)
- Plain tea (if it doesn’t upset your stomach)
Getting Better Phase
After a few days, you can add easy foods that don’t make your colon work hard:
- White rice (not brown)
- Plain pasta
- Eggs
- Smooth yogurt
- Cooked carrots without skin
Back to Normal
Once you’re feeling better, slowly add more fiber to keep your poop soft and moving well. Foods high in fiber include fresh fruits, vegetables, and whole grains. They soften your poop and help it pass through your colon. But add fiber slowly – too much too fast can cause gas and pain.
The Myth About Seeds and Nuts
Here’s some good news that might surprise you. Avoiding nuts and seeds as a preventive measure is no longer recommended since there’s no evidence that these play a role in causing inflammation in the diverticula. For years, doctors told people with diverticulitis to avoid popcorn, nuts, and seeds. They thought these foods would get stuck in the pouches. But new research shows this isn’t true – you can enjoy these healthy foods!
How Long Until Your Poop Gets Normal Again?
Most people start to feel better within a few days of starting treatment. Your poop slowly gets back to normal as the swelling goes down. The blood and mucus go away first, usually within a week. The shape and texture take longer to fix – maybe two to three weeks.
Most cases of diverticulitis undergo successful management in the outpatient setting with oral antibiotics and temporary dietary restrictions. This means you can usually get better at home without going to the hospital.
Signs You’re Getting Better
- Less blood in your poop each day
- Poop gets softer and easier to pass
- Shape becomes more normal (not pencil-thin)
- Less mucus covering your poop
- More regular bathroom trips
Living With Diverticulitis: Your Daily Poop Guide
Managing diverticulitis means paying attention to your poop every day. Keep a simple diary of what your poop looks like. Note the color, shape, and if you see blood or mucus. This helps you catch problems early.
Daily Habits That Help
Get regular exercise – this helps your bowels work correctly and reduces pressure inside your colon. Try to exercise at least 30 minutes most days. Even a simple walk after dinner helps keep things moving.
Drink lots of water – at least 6 to 8 glasses a day. Water keeps your poop soft and helps fiber do its job. Think of fiber like a sponge – it needs water to work right.
Stress and Your Gut
Stress can make digestive conditions worse because our brain and gut are closely connected. When you’re stressed, your gut feels it too. Try simple breathing exercises or gentle stretching when you feel worried about your next flare-up.
Research Behind Poop Changes
Scientists keep learning new things about why diverticulitis changes your poop.
The Fiber Connection
Research from Mayo Clinic found patients with low fiber intake had poop that took 80 hours to pass through, while those with high fiber intake only took 34 hours. Slower poop movement means more pressure in your colon, which can make diverticulitis worse.
The Bacteria Story
Recent studies show changes in gut bacteria play a big role in diverticulitis, with different bacteria levels found in people with the condition compared to those without. Your gut has trillions of bacteria, and when the balance gets messed up, it can trigger inflammation.
Who Gets It Most?
In the U.S., 30% of people over 50, 50% of people over 60, and 75% of people over 80 have diverticular pouches. But remember – most never get sick from them! Taking care of your gut health can help you stay in the lucky group.
Beyond Poop: Other Body Changes
Diverticulitis doesn’t just change your poop – it affects your whole body.
Weird Smells in Odd Places
Your urine might smell bad if diverticulitis causes a tunnel (called a fistula) to form between your colon and bladder. Women might notice foul-smelling vaginal discharge if a fistula connects the colon and vagina. These problems need surgery to fix, so tell your doctor right away if you notice these symptoms.
The Energy Drain
Diverticulitis can cause fatigue and weakness because pain makes you tired, your body’s fighting infection, and you might not be eating enough. It’s like your body is running a marathon while sitting still – fighting infection takes a lot of energy.
Preventing Future Flare-Ups
You can’t make the pouches go away, but you can stop them from getting infected again.
The New Research on Diet
A recent study found that people with diverticulosis were more likely to report loose stools, urgency, passing mucus, and going to the bathroom more often. This means paying attention to these early warning signs might help you prevent a full flare-up.
Simple Prevention Steps
- Eat 25-35 grams of fiber daily (work up slowly)
- Drink water with every meal and snack
- Move your body every day
- Don’t smoke (it doubles your risk)
- Keep a healthy weight

When Different Treatments Are Needed
Not everyone with diverticulitis gets the same treatment. It depends on how bad your case is.
Mild Cases
If you have mild diverticulitis without complications, your doctor may recommend following a special diet plan with liquid foods for a few days, then slowly adding low-fiber foods. You’ll take antibiotics at home and rest.
Serious Cases
Some people need stronger help. For severe cases, intravenous antibiotics, hospital admission, and complete bowel rest may be recommended. This means no food by mouth while your gut heals.
Surgery Options
Most people never need surgery, but it’s good to know the options. After surgery, you need to rest and avoid lifting heavy objects. Your doctor may recommend a colonoscopy six or more weeks after surgery to check everything healed well.
The Good News About Recovery
Here’s what should give you hope: After the first diverticulitis attack, recurring inflammations are a lot less likely to lead to complications. Your body gets better at dealing with the problem. Most people learn to manage their condition and live normal, happy lives.
Research from Johns Hopkins Medicine found that people who follow healthy habits have much lower rates of diverticulitis flare-ups. Simple changes in what you eat and how you live make a real difference.
