When Is Rectal Bleeding More Than Just Hemorrhoids?

Hemorrhoids are common, affecting about one in 20 Americans, and they are one of the most common causes of rectal bleeding. However, seeing blood after a bowel movement does not necessarily mean hemorrhoids are to blame. Anal fissures, inflammatory bowel disease, colon polyps, diverticular disease, and colorectal cancer can also cause rectal bleeding, and some of these conditions require prompt evaluation and treatment. For this reason, unexplained or recurrent rectal bleeding deserves evaluation by a colorectal surgeon who can determine where the bleeding is coming from and whether further testing is needed. 

Continue reading to learn what hemorrhoid bleeding typically looks like, how it differs from bleeding caused by other colorectal conditions, and when to seek care from the best colorectal surgeon in Los Angeles for an accurate diagnosis and personalized treatment.

What Does Hemorrhoid Bleeding Usually Look Like?

Internal hemorrhoids are swollen veins inside the anus or lower rectum. Their most recognizable symptom is painless, bright red rectal bleeding. You may notice blood on toilet paper, streaks on the outside of the stool, or blood dripping into the toilet after a bowel movement. Internal hemorrhoids can also prolapse, causing tissue to protrude through the anal opening.

External hemorrhoids develop under the skin around the anus. They may cause itching, tenderness, swelling, or a hard, painful lump. A blood clot within an external hemorrhoid can cause sudden and significant pain.

Other common hemorrhoid symptoms include:

• Pain or discomfort during or after bowel movements
• Anal itching or irritation
• Swelling around the anus
• Prolapsed tissue
• Mucus leakage or soiling
• A sensation of fullness or incomplete evacuation

The appearance of the blood is useful information, but it is not a diagnosis. Bright red blood makes an anorectal source such as hemorrhoids more likely, but the pattern of bleeding must be considered along with your age, medical history, family history, and other symptoms.

What Types of Rectal Bleeding Need Evaluation?

Rectal bleeding deserves medical attention when the pattern does not fit typical hemorrhoidal bleeding or when other concerning symptoms are present: 

• Blood mixed throughout the stool rather than only on its surface
• Black or tarry stools
• Persistent or recurrent rectal bleeding
• A change in bowel habits
• New constipation or diarrhea
• Narrower-than-usual stools
• Persistent abdominal or rectal pain
• Unexplained weight loss
• Unusual fatigue, weakness, dizziness, or shortness of breath
• A personal or family history of colorectal cancer or polyps
• A history of inflammatory bowel disease

Additionally, the American Society of Colon and Rectal Surgeons recommends that patients with hemorrhoids and rectal bleeding should undergo a complete evaluation of the colon because conditions such as colorectal cancer, inflammatory bowel disease, diverticular disease, and other forms of colitis can also cause bleeding.

Do I need to Get Rectal Bleeding Checked if I’m Young?

A common misconception is that younger age makes rectal bleeding harmless. Age and risk factors can sometimes influence the type of evaluation you get, but they do not make unexplained bleeding something to ignore. 

How Does a Colorectal Surgeon Tell Hemorrhoids From Other Causes of Bleeding?

Getting an accurate diagnosis starts with a detailed history. A colorectal surgeon will want to know when the bleeding began, how frequently it occurs, whether blood is on the toilet paper or mixed with stool, whether you have pain or prolapse, and whether your bowel habits have changed. Your personal and family history also helps determine whether additional testing is appropriate.

The physical examination may include inspection of the anal area, a digital rectal examination, and anoscopy. An anoscope allows the surgeon to directly examine the lining of the anus and lower rectum for internal hemorrhoids and other abnormalities.

Depending on the findings, the best colorectal surgeon in Los Angeles may recommend additional evaluation of the colon, such as a colonoscopy. This is particularly important when the bleeding pattern, medical history, or other symptoms raise concern for a source higher in the digestive tract.

Can You Treat Hemorrhoids Without Surgery?

Many hemorrhoids can initially be managed with dietary and bowel-habit changes, including increasing fiber, staying hydrated, and avoiding straining or prolonged sitting on the toilet. When those measures are not enough, office-based procedures can treat selected internal hemorrhoids without traditional surgery. The best hemorrhoid treatment in Los Angeles is tailored to the type, severity, and behavior of the hemorrhoids rather than using one procedure for every patient. 

Some of the best non-invasive hemorrhoid treatments in Los Angeles include:

• Sclerotherapy: An injected solution causes an internal hemorrhoid to shrink.
• Infrared coagulation: Infrared energy reduces the hemorrhoid's blood supply and encourages shrinkage.
• Rubber band ligation: A small band cuts off the blood supply to a symptomatic internal hemorrhoid.
• Laser hemorrhoid surgery: The best laser treatment for hemorrhoids in Los Angeles can be used in certain patients as a tissue-sparing approach.
• Transanal hemorrhoidal dearterialization: Doppler guidance identifies hemorrhoidal arteries, reducing blood flow without removing the hemorrhoidal tissue.
• Excisional hemorrhoidectomy: Selected patients with advanced internal and external disease may benefit from surgical removal.
• Anal skin tag removal: Persistent skin tags can be removed when they cause irritation or hygiene problems.
