The presence of blood in the stools, medically known as "hematochezia," is a concerning symptom that can worry elderly individuals and their loved ones. This manifestation can be caused by various factors, some less serious than others, but it always requires a thorough medical evaluation. In this article, we will explain why blood can appear in the stools of the elderly and what the underlying causes might be.
Hemorrhoids
Hemorrhoids are one of the most common causes of blood in the stools, especially in elderly individuals. They result from inflammation of the veins in the rectal or anal region. Hemorrhoids can bleed during bowel movements, often resulting in bright red stools.
Digestive tract conditions

Several gastrointestinal conditions can lead to bleeding in the stools in the elderly, including:
- Stomach or duodenal ulcers: These ulcers can bleed and result in black, tarry stools.
- Diverticular disease: Inflammation of diverticula in the colon can cause rectal bleeding.
- Ulcerative colitis or Crohn's disease: These inflammatory bowel diseases can lead to ulcerations and bleeding.
- Colorectal cancer: This is one of the most serious concerns, as bleeding is one of the symptoms of colorectal cancer.
Upper digestive tract bleeding
When bleeding originates from the upper part of the digestive tract, such as the esophagus, stomach, or duodenum, the blood may be partially digested, resulting in black, tarry stools. This is known as melena and requires immediate medical attention.
Medications
Some medications, such as anticoagulants (which prevent blood clotting) or nonsteroidal anti-inflammatory drugs (NSAIDs), can increase the risk of gastrointestinal bleeding in the elderly.
What to do if there is blood in the stools?
The presence of blood in the stools is a symptom that should be reported to a healthcare professional as soon as possible. The first step is to determine the underlying cause of the bleeding through medical tests such as stool analyses, colonoscopies, endoscopies, or X-rays.
Early identification of the cause is crucial, as it can guide treatment and improve recovery prospects. Whether it is a benign condition like hemorrhoids or a more serious issue like colorectal cancer, medical evaluation is imperative to ensure appropriate management.
When to seek medical attention for blood in stools
| Symptom | Urgency | Recommended Action |
|---|---|---|
| Bright red blood after wiping | Low | Monitor; likely hemorrhoids, but consult a doctor if persistent. |
| Black, tarry stools (Melena) | High | Seek immediate medical attention; possible upper GI bleeding. |
| Ongoing rectal bleeding with abdominal pain | Moderate | Schedule a doctor’s visit; could indicate diverticular disease. |
| Blood in stools with weight loss | Critical | Urgent medical evaluation needed; possible colorectal cancer. |
| Blood in stools after taking NSAIDs or blood thinners | High | Contact a doctor immediately; medication-induced bleeding is a risk. |
The presence of blood in the stools of the elderly should never be ignored. It is a symptom that requires prompt medical assessment to determine the underlying cause and establish an appropriate treatment plan. The earlier the problem is identified, the better the chances of effective management.
