Hundreds of people see blood in the toilet when they have a bowel movement, but ignore it, and most don’t even tell a doctor. This can be dangerous, as rectal bleeding can be a symptom of serious health conditions, including colorectal cancer.
“Rectal bleeding is very common. It’s one of the most common complaints that comes up in primary care and [gastroenterology] visits,” said Samir Gupta, a gastroenterologist and professor of medicine at UC San Diego Health. “Any blood in the stool is abnormal. It doesn’t automatically mean cancer, but it’s definitely not something to be assumed is normal and warrants no further attention,” said Sophie Balzora, a gastroenterologist and clinical professor in the department of medicine at NYU Grossman School of Medicine.
Bleeding when you poop, also called rectal bleeding, has several causes, and some are more worrisome than others. While most cases are benign and caused by conditions such as hemorrhoids or anal fissures, it’s crucial not to dismiss the symptom without seeking medical attention.
If you notice blood in your stool, it’s important to ask yourself whether you need immediate evaluation at an emergency department. Signs that indicate the need for an emergency room visit include passing large amounts of blood, frequent bloody bowel movements, severe abdominal pain, passing out, feeling short of breath, having a fever along with bloody stools, or experiencing low blood pressure.
Even if there isn’t an emergency, you should make an appointment with a primary care doctor or gastroenterologist. During the appointment, expect a thorough evaluation and potentially bloodwork to evaluate for low red blood count or inflammation, and potentially a rectal exam. Depending on the findings, a colonoscopy may be recommended.
“It’s easy to dismiss symptoms. It’s human nature,” said Balzora. “Your health is the absolute priority and blood in stool is never normal. You shouldn’t be afraid of what it might be. Take that next step and talk about it with a health-care professional.”
