What Your Toilet Bowl Could Be Telling You About Your Health

By now, you’re probably well aware that prevention is key when it comes to protecting yourself against diseases like cancer. You might already be doing breast self-exams or getting your moles checked regularly, but there’s another part of your health you should be keeping an eye on — and it’s in your toilet bowl.

Colorectal cancer, often called colon cancer, is the third most common cancer in the United States for both men and women. While widespread screening has significantly reduced cases in people over 50 since the 1980s, there’s been a troubling increase in early-onset colorectal cancer, particularly in younger adults.

In fact, researchers have discovered that people born in 1990 have twice the risk of colon cancer and four times the risk of rectal cancer compared to those born in 1950. This rise in younger cases coincides with a steady decline in colorectal cancer among adults over 55, thanks in large part to routine screening and early detection.

Why Are More Young People Getting Colorectal Cancer?

The exact reasons for the rise in early-onset colorectal cancer remain unclear. Experts like Dr. Lisa Ganjhu, a clinical associate professor in gastroenterology and liver diseases at NYU Langone Medical Center, suggest it may be related to changes in diet, increased stress, or other lifestyle factors. However, more research is needed to pinpoint the exact causes.

What’s especially concerning is that younger people are more likely to ignore or dismiss early symptoms of colorectal cancer. The National Cancer Institute reports that this delay in seeking medical advice often leads to later diagnoses when symptoms like weight loss or rectal bleeding become severe and the disease is harder to treat.

This trend is particularly alarming for women, as colorectal cancer is the third leading cause of cancer deaths among women, right behind breast cancer and lung cancer, according to the Centers for Disease Control and Prevention (CDC).

But there’s good news: Colorectal cancer is one of the most preventable forms of cancer. Early detection and timely action can make all the difference. That’s why it’s crucial to recognize the warning signs and see a doctor if you notice anything unusual, especially if you have a family history of the disease.

Key Symptoms of Colorectal Cancer to Watch For

Here are some common signs that shouldn’t be ignored:

1. Blood in the Toilet Bowl or on Toilet Paper

A small amount of bright red blood on toilet paper is usually harmless and might indicate a minor issue like a hemorrhoid or a small fissure. However, if you notice significant amounts of blood, or if your stool appears maroon or black, it’s time to call your doctor. Black or dark stools can signal bleeding further up in the colon, according to Dr. Ganjhu.

2. Persistent Constipation or Diarrhea

Everyone deals with constipation or diarrhea from time to time, but when these issues persist, it could be a sign of something more serious. Prolonged constipation can indicate a blockage in the colon, especially if stool becomes harder and struggles to pass through, particularly near the rectum. Similarly, diarrhea lasting more than a few days could also be a warning sign and should prompt a visit to your doctor.

3. Unexplained Stomach Cramping

Random stomach cramps or spasms in the lower abdomen might just be gas — or something more concerning. If the pain is unusual for you, or if you feel the urge to poop but can’t, don’t dismiss it. Your doctor will want to investigate further.

4. Changes in the Shape of Your Stool

If something is blocking your colon, your stool may become narrower or take on a ribbon-like shape as it tries to pass through the obstruction. While stool shape can vary for many reasons, a consistent change over several days is worth discussing with your doctor.

5. Low Iron or Anemia

An iron deficiency, or anemia, can be an early symptom of colorectal cancer. Tumors in the colon or rectum often cause slow, chronic bleeding, which reduces the number of red blood cells and hemoglobin in the blood. Signs of anemia include fatigue, dizziness, pale skin, cold hands and feet, rapid or irregular heartbeat, and difficulty concentrating.

What Can You Do to Protect Yourself?

Colorectal cancer is highly preventable, especially with regular screening and early detection. The American Cancer Society recommends that adults at average risk start screening at age 45, but if you have a family history of colorectal cancer or other risk factors, you may need to start earlier.

Screening methods like colonoscopies not only detect cancer but can also help prevent it by identifying and removing precancerous polyps before they turn into cancer.

If you notice any of the symptoms mentioned above, don’t wait. Book an appointment with your doctor as soon as possible. They may recommend tests such as a colonoscopy or imaging studies to get a closer look at what’s happening in your digestive system.

The Bottom Line

While colorectal cancer remains a serious health concern, the encouraging news is that it’s one of the most preventable and treatable forms of cancer when caught early. By paying attention to the signs your body is giving you — even the ones in your toilet bowl — you can take proactive steps to protect your health.

And if you or someone you love is currently dealing with cancer, remember that you’re not alone. Support is available. Organizations like The Cancer Council offer free assistance through their helpline at 13 11 20, Monday to Friday, from 9 am to 5 pm.

Your health is worth it. So take the time to check in with your body — and your toilet bowl — regularly. It could save your life.
