 tinkerbelle - Mon Jan 23, 2006 3:32 pm

Hello my boyfriend is 25 and for the past 2 years he has been having trouble with his bowels. he has never has surgery and his auntie died of bowel cancer, which is worrying him. he poo's about 5 times a day and gets very bad stomach pains.He has noticed before he has blood in his stools but today in all of them he has had blood in his poo. the first bit of his poo is hard then the last bit is soft and thats where he usually gets the blood. he has noticed the toliet water is red as well. the doctor has giving him some tablets because they said it was heart burn but he had to stop that because it made his stomach pains worse. he doesnt usually eat fatty food.

User avatar Dear tinkerbelle,

Fresh blood in stools, are usually due to lower GI bleeding.
Causes include
- Hemorrhoids or piles, they represent the most common cause of lower GI bleeding, and are easy to be diagnosed by clinical examination. Anorectal fissures as well can result in bleeding per rectum and are easily diagnosed.

- These symptoms and signs can be manifestations of inflammation of the mucosa lining the rectum or the rectum and colon a condition known as proctitis or proctocolitis respectively.
These conditions are either due to infectious diseases or non infectious disease as a part of inflammatory bowel disease (including Crohn's disease and Ulcerative colitis)
Infections include a variety of parasites and protozoa e. g. Entamoeba histolytica and Salmonella or
a part of sexually transmitted disease like herpes simplex and Chlamydia.
Diagnostic tests include stool analysis to check for parasites and protozoa. Samples are collected before receiving any medication and should be repeated for 3 times to find the possible organism causing the infection.
Other tests according to the suspected cause like segmoidoscopy and Colonoscopy to visualize the lining mucosa and take biopsy if needed.

- Inflammatory bowel disease,
Commonly people who have IBS complain off
Abdominal pain or colic
A bloated abdomen
Gaseous distension
Either Diarrhea or constipation or an alternating between both of them
Mucus or less commonly blood containing stools
Other diseases that can give similar pictures to IBS and have to be excluded are Gastritis, GERD, and peptic ulcer. But blood in stools is usually occult and not fresh red.

- Polyps, diverticulosis and colon cancer.
Colonoscopy is of choice in the diagnosis of these cases.

He has to be properly checked and investigated. Only by complete history, physical examination and investigations, the correct diagnosis can be reached.
