What Does a Healthy Bowel Movement Look Like?

First things first, “everyone's bowel movements are different, but a healthy one almost looks like theshape of the colon, is soft and does not cause pain upon exit,” Dr. Sonpal says. For reference, check out theBristol Stool Chart.

"Eating more plant-based foods will increase the amount ofsoluble fiberin the stool," which will become fluffy, softer and easier to pass, Dr. Sonpal says. That's because fiber "causes more distention of the rectum, making you go to the bathroom more frequently," he explains.

Moreregular poopsmay also occur if you're working out more.

"Exercise makes everything in your abdomen compress," Dr. Sonpal says. In other words, "your abdominal muscles are literally promoting you to poop."

2. You’re Constipated

If you're trying to build muscle or stay satiated at meals, you might be introducing more lean proteins into your daily menu. But eating too much of this mighty macro may bind your bum.

Dense proteins — which take longer to digest — can lead toless frequent bathroom tripsand constipation, Dr. Sonpal says. The result: Your stools may become hard, chunky and feel uncomfortable on the way out.

Cutting carbs from your diet— often a go-to weight-loss strategy — can cause constipation too. That's because when you slash too many carbs, you also eliminate a lot of essential fiber sources, such as whole grains, fruits and legumes, which keep your poop schedule on track and running smoothly.

To combat these constipating effects, be sure to balance your diet by drinking plenty of water and filling your plate with fibrous foods, Dr. Sonpal says.

如果你按照carb-restricted饮食like keto, you can still reach your daily fiber quota by sticking tonon-starchy vegetables(like leafy greens, carrots and squash) andlow-carb fruitslike avocado and raspberries.

Women (up to age 50) should get about 25 grams of fiber per day while men should shoot for 38 grams, according toHarvard Health Publishing.

3. You Have Diarrhea

Alternatively,low-carb eating planscan also produce runny poops. Take the keto diet for example. Since sugar is a major no-no on this diet program, many keto devotees may consume foods containing low-carbartificial sweetenersand sugar alcohols. These sugary alternatives, which are difficult to digest, can have a laxative effect leading to liquidy poops, according toHarvard Health Publishing.

What's more, keto requires you to eat a lot of fat. But consuming too many fatty foods candisrupt digestionand result in the runs as well. This can be a double digestive whammy if you're chomping on more cheese and you have a lactose intolerance (about 65 percent of us do, according to theU.S. National Library of Medicine).

4. Your Poop Color May Change

Does the shade of your stool seem different lately? That's because your poop's pigment is impacted by what 's on your plate, according to theCleveland Clinic. So, if you're eating a rainbow of fruits and veggies, expect your feces to reflect that.

For example, dark, leafy greens can generate bright green poop while beets and cherries may turn your stool reddish. Meanwhile, blueberries can taint your toilet waste a deep blue (or even black) and carrots can cause orange-hued poop.

But if the color changes persist, or you can't connect them to anything you ate, it might be cause for concern, per the Cleveland Clinic. Red or black poop may indicate blood in the stool, while gray stool could signal an issue in the pancreas or bile ducts.

In these cases, contact a medical professional who can help you identify any serious problems.
