Why does bleeding occur?
I am unsure which specialty this belongs to.
As for my question: why do I experience bleeding every time I have a bowel movement? Sometimes I have to strain to pass stool, which I assume would cause bleeding, but why does it still bleed even when I don't strain? This has been ongoing for about 2 or 3 months, and I don't understand why this is happening.
Also, if I eat too much chocolate, could that cause any issues?

Causes of rectal bleeding: 1.
Hemorrhoids.
If the stool is hard, it can rupture the dilated veins, leading to a dripping blood phenomenon known as hemorrhoids.
2.
Colorectal tumors with associated ulcers can also cause bleeding.
3.
Rectal ulcers due to inflammation and erosion may also result in bleeding.
It is recommended to undergo a thorough examination at a hospital.
Thank you.

More Info
Experiencing blood during bowel movements can be concerning and may indicate several underlying issues. It's essential to understand that this symptom should not be ignored, especially since it has persisted for two to three months. The presence of blood in your stool can be attributed to various causes, and identifying the correct one is crucial for effective treatment.
One of the most common reasons for blood during bowel movements is hemorrhoids. Hemorrhoids are swollen veins in the lower rectum or anus that can cause bleeding, especially during bowel movements. They can be internal or external, and symptoms may include pain, itching, and discomfort. Straining during bowel movements, often due to constipation, can exacerbate this condition, leading to bleeding.
Another potential cause is anal fissures, which are small tears in the lining of the anus. These can occur due to passing hard stools or straining, and they can be quite painful, often resulting in bright red blood on the stool or toilet paper.
In more severe cases, blood in the stool can indicate gastrointestinal issues such as diverticulosis, inflammatory bowel disease (IBD), or even colorectal cancer. Diverticulosis involves the formation of small pouches in the colon wall, which can become inflamed or infected, leading to bleeding. IBD, which includes Crohn's disease and ulcerative colitis, can cause inflammation and ulceration in the digestive tract, resulting in blood in the stool. Colorectal cancer, while less common, is a serious condition that can present with rectal bleeding, especially in individuals over the age of 50 or those with a family history of the disease.
Regarding your question about chocolate consumption, while eating chocolate in moderation is generally safe, excessive intake can lead to digestive issues, including diarrhea or constipation, which may indirectly contribute to straining during bowel movements. However, chocolate itself is not a direct cause of rectal bleeding.
Given the duration of your symptoms, it is crucial to seek medical attention. A healthcare provider, likely a gastroenterologist, can perform a thorough evaluation, which may include a physical examination, a review of your medical history, and possibly diagnostic tests such as a colonoscopy or imaging studies to determine the exact cause of the bleeding.
In summary, blood during bowel movements can stem from various conditions, ranging from benign issues like hemorrhoids and anal fissures to more serious gastrointestinal diseases. It is essential to consult a healthcare professional to receive an accurate diagnosis and appropriate treatment. Ignoring these symptoms can lead to complications, so timely intervention is key to managing your health effectively.
