Key red flags to watch for after 65 include blood in or on the stool (bright red or black), persistent color changes such as black, pale or clay, or yellow greasy stool, ongoing constipation or diarrhea, sudden changes in stool shape or size, pain with bowel movements, unexplained weight loss with bowel changes, and a frequent feeling of incomplete emptying. There are several factors to consider and clear guidance on when to seek care; see below for the complete details that explain what each sign can mean and which next steps to take.
As we age, our digestive system changes just like the rest of our body. For women over 65, paying attention to bowel habits is an important part of staying healthy. While many changes in stool are harmless and related to diet, hydration, or medications, some signs should not be ignored.
This guide explains what to look for when pooping, focusing on seven red flags that may signal a health issue. The goal is to help you notice meaningful changes—without creating unnecessary worry—and to know when it's time to speak to a doctor.
After age 65, the risk of digestive conditions increases due to factors such as:
Because of this, bowel changes that might be minor earlier in life can sometimes signal something more serious later on.
Seeing blood in your stool is one of the most important things to notice when pooping.
What it may look like:
What it can mean:
While bright red blood is often from the lower bowel, black stool can mean bleeding higher in the digestive tract. Either way, blood should never be ignored, especially in women over 65.
👉 Speak to a doctor promptly, even if the bleeding seems small or painless.
Occasional color changes are normal, especially after eating certain foods or taking supplements. However, persistent or unexplained color changes deserve attention.
Colors to watch for:
These changes may point to problems with digestion, bile flow, liver health, or bleeding.

It's normal to have an off day now and then. What matters is pattern and duration.
Red flags include:
In older women, long-term constipation may increase the risk of bowel blockage, hemorrhoids, or fecal impaction. Chronic diarrhea can lead to dehydration and nutrient loss.
These symptoms may be linked to:
👉 Speak to a doctor if bowel habits change and stay different.
Stool shape can provide clues about bowel health.
What to look for when pooping:
A sudden or ongoing change in shape—especially narrow stools—can sometimes suggest a narrowing in the colon. While this can be caused by constipation, it can also be related to growths or inflammation.
If the change is new and lasts more than a couple of weeks, it's worth getting checked.
Mild discomfort from constipation happens to many people. However, pain that is frequent, severe, or worsening is not normal.
Possible causes include:
Pain combined with bleeding, fever, or weight loss is especially important to report.
👉 Do not dismiss ongoing pain as "just aging." Speak to a doctor for proper evaluation.
Losing weight without trying—especially when combined with changes in stool—should always be taken seriously.
Watch for:
In women over 65, this combination can sometimes signal digestive diseases, malabsorption, or cancer. Early evaluation often leads to better outcomes.
A frequent feeling of incomplete emptying, even after using the toilet, can be frustrating and concerning.
This may be linked to:
If this feeling is new, persistent, or worsening, it deserves medical attention.
Not every bowel change is serious. Many are caused by:
Still, the key is consistency and change over time. A short-term issue that resolves is less concerning than a symptom that sticks around.
Contact a healthcare professional promptly if you notice:
Anything that could be life-threatening or serious should never be handled alone or delayed.
Knowing what to look for when pooping is not about being alarmed—it's about being informed. Your body often gives early signals when something isn't right. Paying attention can lead to earlier diagnosis, simpler treatment, and better long-term health.
If something feels off, trust that instinct and speak to a doctor. Asking questions and seeking care is a sign of strength, not worry.
