Red chunks in your poop can be harmless, like from beets or tomatoes, but often signal gastrointestinal bleeding from issues like hemorrhoids, anal fissures, diverticulosis, IBD, infections, or even polyps/cancer, requiring a doctor's evaluation to determine if it's food, clots, or blood. It's crucial to see a doctor for any unexplained blood in your stool, as it needs proper diagnosis and treatment.
There are several things that can cause bleeding from your bottom or blood in your poo. Bright red blood may come from swollen blood vessels (haemorrhoids or piles) in your back passage, or non-cancerous growths (polyps). It may also be caused by bowel cancer.
Blood clots in stool are a sign of bleeding somewhere in your gastrointestinal (GI) tract. Bright red blood in your stool usually signals bleeding from your lower colon or rectum, while dark red blood can indicate bleeding higher in the colon or small bowel.
Sometimes, you may see undigested food fragments in stool. This usually is high-fiber vegetable matter, which usually isn't broken down and absorbed in your digestive tract. At times, undigested food is a sign of poor chewing and fast eating. Make sure that you chew your food well.
Seek medical advice for any blood in stool. Seek emergency care if you notice: Large amounts of blood. Lightheadedness.
Blood in stool from cancer can appear as bright red streaks (from lower down in the colon/rectum) or dark, black, tarry stools (from higher up in the digestive tract), mixed with or coating the feces, often with other symptoms like thin stools, fatigue, or changes in bowel habits, but it can look like blood from many other causes, so seeing a doctor for diagnosis is crucial.
Because the intake of iron, bismuth or foods like beets can give the stool the same appearance as bleeding from the digestive tract, a doctor must test the stool for blood before offering a diagnosis. Other symptoms: Bright red blood coating the stool.
Rectal bleeding is a symptom of many different conditions, including hemorrhoids, anal fissures, inflammatory bowel disease (IBD) and colorectal cancer. You may notice rectal bleeding on your toilet paper when you wipe or when you see blood in your stool.
Change in the Appearance of the Stool
A Thin, narrow, or ribbon-like stool could indicate changes inside your colon. Color: Blood, darkened, or tarry (black) stool can signal issues inside the colon. Your doctor can help determine the cause.
Like hemorrhoids, colon cancer can cause rectal bleeding, but the bleeding is typically more persistent and the blood may be darker in color. Additionally, colon cancer can cause other symptoms that are not generally associated with hemorrhoids, such as: Abdominal pain, cramping or gas.
Black or tarry stools usually mean bleeding is happening higher up in your digestive tract, like in the stomach or small intestine. Bright red blood mostly comes from the lower parts, like the colon or rectum. Blood clots may be mixed inside the stool or just seen on the surface as small, dark lumps.
Small amounts of blood in the toilet bowl or on toilet paper are often linked to conditions like hemorrhoids or anal fissures. However, certain foods such as beets, tomatoes, or foods with red food coloring can also cause stools to appear reddish.
Sometimes this may only look like small amounts or streaks of bright red blood noticed on toilet paper after wiping. Some people might see small drops in or on their stool in the toilet. The most likely causes are hemorrhoids, polyps, tears or fissures, or certain inflammatory conditions.
Hemorrhoid blood typically looks like bright red blood on toilet paper, in the toilet bowl, or on the outside of stool, often appearing as streaks or drops, usually without pain. Darker blood or black, tarry stools suggest bleeding from higher up in the digestive tract, while a thrombosed hemorrhoid might appear as a hard, bluish or purplish lump near the anus, potentially with bleeding.

Symptoms that are common to both Crohn's disease and ulcerative colitis include:
Symptoms of intestinal failure may include:
Crohn's Ulcers and Bleeding
Blood or stool that's dark red, maroon, or tarry black is usually coming from bleeding higher up in the colon, small intestine, or even the stomach, Dr. Bedford notes. It's darker-colored because by the time you see it, it's been at least partially digested.
Larger amounts of mucus in stool, associated with diarrhea, may be caused by certain intestinal infections. Bloody mucus in stool or mucus along with belly pain may signal a more serious condition, such as Crohn's disease, ulcerative colitis and even cancer.
Most often, passing small blood clots during your period isn't a cause for concern. The amount, length and frequency of menstrual bleeding vary from month to month and from person to person. But if you pass large blood clots that are bigger than a grape, seek medical care.
The colour of the blood depends on where the blood is coming from. Spots of red blood indicate the bleeding is coming from your large intestine or rectum. If the blood is dark red and mixed in with your poo it may be from higher up in your bowel, such as your colon or small intestine.
Immediate action required: Go to A&E or call 999 if: you're bleeding non-stop. there's a lot of blood – for example, the toilet water turns red or you see large blood clots.
Guaiac-based fecal occult blood test (gFOBT): This traditional test uses guaiac, a plant-based substance that changes color when exposed to blood components. The test detects a component of hemoglobin called heme, which gives red blood cells their oxygen-carrying ability.
