Rectal bleeding
I don't like drinking water, and for the past week, I've been experiencing significant rectal bleeding during bowel movements, but there is no pain or discomfort.
I would like to know if this could be cancer or hemorrhoids?

Dr. Ke Fangxu reply Surgery
At the age of 17, the likelihood of developing colorectal cancer is not zero, but it is generally very low.
Based on your description, it seems more like hemorrhoidal bleeding.
I recommend starting with a light diet and maintaining a good lifestyle.
Spicy, irritating, and greasy foods should be avoided, and increasing dietary fiber can also be beneficial.
If symptoms persist without improvement, you may want to consult a physician for medication or to undergo a colonoscopy.

When it comes to the presence of blood in stool, it is essential to approach the situation with caution and seek medical advice. Blood in the stool can be caused by a variety of conditions, ranging from benign to serious. The two most common causes are hemorrhoids and colorectal cancer, but other conditions such as diverticulosis, inflammatory bowel disease (IBD), and gastrointestinal infections can also lead to this symptom.
Hemorrhoids are swollen veins in the lower rectum or anus that can cause bleeding, especially during bowel movements. The blood from hemorrhoids is typically bright red and may be seen on the toilet paper or in the toilet bowl. Hemorrhoids are often associated with straining during bowel movements, constipation, or prolonged sitting. They can be painful or painless, depending on whether they are external or internal.
On the other hand, colorectal cancer can also present with blood in the stool, but the characteristics of the blood may vary. Blood from cancer may appear darker or mixed with the stool, indicating that it is coming from higher up in the gastrointestinal tract. Other symptoms of colorectal cancer can include changes in bowel habits, unexplained weight loss, fatigue, and abdominal discomfort. However, it is crucial to note that many people with hemorrhoids may not experience any pain or discomfort, which can make it challenging to differentiate between the two conditions based solely on symptoms.
Given your situation of experiencing significant blood loss in the stool without pain or other discomfort, it is vital to consult a healthcare professional. They will likely recommend a thorough evaluation, which may include a physical examination, a digital rectal exam, and possibly further diagnostic tests such as a colonoscopy. A colonoscopy allows for direct visualization of the colon and rectum, enabling the physician to identify any abnormalities, including hemorrhoids, polyps, or tumors.
In addition to a colonoscopy, your doctor may also order blood tests to check for anemia, which can occur due to significant blood loss. They may also inquire about your dietary habits, hydration status, and any other symptoms you may have experienced.
It is also worth mentioning that lifestyle factors, such as inadequate water intake, can contribute to constipation and straining during bowel movements, which may exacerbate hemorrhoids. Ensuring adequate hydration, a high-fiber diet, and regular physical activity can help prevent constipation and reduce the risk of developing hemorrhoids.
In summary, while hemorrhoids are a common cause of blood in the stool, the presence of blood should never be ignored, especially if it is significant. It is essential to seek medical evaluation to determine the underlying cause and receive appropriate treatment. Early detection and intervention are crucial, particularly for serious conditions like colorectal cancer. Therefore, do not hesitate to reach out to a healthcare provider for a thorough assessment and peace of mind.
