Red or maroon stool after age 65 can be caused by harmless foods or supplements, but it can also point to problems that need care. The five common causes women should know are hemorrhoids, anal fissures, diverticular bleeding, colorectal polyps or cancer, and medication-related bleeding. There are several factors to consider; seek medical advice sooner if episodes recur, there is no food trigger, blood is mixed into stool, or you have weakness, dizziness, belly pain, weight loss, bowel habit changes, a history of colon disease, or you take blood thinners, and see the complete guidance below for when home monitoring is reasonable versus urgent evaluation.
Seeing poop red can be surprising and uncomfortable—especially after age 65. While red stool is often harmless, it can sometimes signal a medical issue that needs attention. For older women, changes in digestion, medications, and long-term health conditions all play a role.
This guide explains what red poop can mean, when to worry, and five common causes women over 65 should know, using clear language and medically credible information. The goal is to inform—not alarm—so you can take sensible next steps.
When people say poop red, they usually mean one of two things:
The shade matters:
Not all red poop is blood. Foods, supplements, and medications can change stool color—sometimes dramatically.
In many cases, red poop is temporary and harmless. Common non-serious reasons include:
If the red color:
Age matters. After 65, the risk of digestive conditions that cause bleeding increases. You should take red poop more seriously if any of the following are true:

Below are five credible, well-recognized causes of red poop in older women, ranging from common to more serious.
Hemorrhoids are swollen veins in or around the anus and are the most common cause of bright red blood in stool.
Typical signs:
Why it's common after 65:
Hemorrhoids are usually not dangerous, but persistent bleeding still deserves a medical check, especially in older adults.
An anal fissure is a small tear in the lining of the anus, often caused by passing hard stool.
Typical signs:
These can heal on their own, but recurring fissures may point to constipation or underlying bowel issues that need treatment.
Diverticula are small pouches that can form in the colon wall, becoming more common with age.
Typical signs:
Diverticular bleeding can be significant and should always be evaluated by a doctor, even if it stops on its own.
This is the cause people fear most—and it's also why red poop should never be ignored after 65.
Possible signs:
Colorectal cancer often starts with no pain at all, which is why screening and early evaluation are critical. Not all bleeding means cancer—but cancer should always be ruled out.
Many women over 65 take medications that can irritate the digestive tract or increase bleeding risk.
Common examples include:
These medications can cause bleeding even without pain. Never stop a prescribed medication without speaking to a doctor, but do report any red poop promptly.
If you speak to a doctor about red poop, they may recommend:
This approach helps identify both common and serious causes safely and accurately.
If you notice poop red in color:
If bleeding continues, worsens, or comes with other symptoms, do not wait.
Red poop after 65 is often caused by manageable conditions, especially hemorrhoids or minor tears. However, age increases the importance of checking for more serious causes.
You do not need to panic—but you should pay attention.
If there is any chance the bleeding could be serious or life-threatening, speak to a doctor as soon as possible. Early evaluation saves lives and often leads to simpler treatment.
When in doubt, listen to your body, seek medical advice, and use reliable tools—like a free online symptom check—to guide your next step.
