Rectal bleeding


Hello, doctor.
Recently, I have been experiencing rectal bleeding for the past three days, primarily bright red blood.
Sometimes, there is a significant amount of blood before the stool is even passed, or I have both blood and stool together.
I often feel the urge to defecate, but the amount is usually small.
The stool color is deep brown, and I also experience abdominal bloating.
Occasionally, I feel discomfort in the lower left abdomen.
After visiting the hospital, it was determined that I might have internal hemorrhoids.
If the symptoms do not improve, a colonoscopy may be necessary to check for rectal issues.
Could you please tell me if the symptoms of rectal bleeding and internal hemorrhoids are the same?

Hello, sir.
Yes, painless rectal bleeding is often due to internal hemorrhoids.
If you are concerned, it is advisable to undergo a direct examination with a flexible sigmoidoscopy or colonoscopy.

Rectal bleeding can be a concerning symptom, and it’s important to understand the potential causes and implications. Based on your description, it seems you have been experiencing bright red blood during bowel movements, sometimes even prior to the stool passing. This can indeed be indicative of hemorrhoids, particularly internal hemorrhoids, which are swollen blood vessels in the rectum that can bleed during bowel movements. However, it’s crucial to differentiate between hemorrhoids and other potential causes of rectal bleeding, as some conditions can be more serious.

Internal hemorrhoids typically present with painless bleeding, and the blood is usually bright red, which aligns with your symptoms. They can also cause a sensation of fullness or pressure in the rectal area. On the other hand, if the bleeding is accompanied by pain, changes in bowel habits, or other gastrointestinal symptoms, it may warrant further investigation.

Rectal bleeding can also be caused by other conditions such as anal fissures, diverticular disease, colorectal polyps, or even colorectal cancer. The presence of deep brown stool and abdominal discomfort, particularly in the left lower quadrant, could suggest other gastrointestinal issues, such as diverticulitis or irritable bowel syndrome (IBS).
Given that you have already consulted a physician who suspects internal hemorrhoids, it’s wise to follow their recommendations. If your symptoms do not improve or worsen, a colonoscopy may be necessary. This procedure allows for direct visualization of the colon and rectum, enabling the physician to identify any abnormalities, such as polyps or lesions, and to take biopsies if needed.

In terms of symptoms, while rectal bleeding from hemorrhoids and other conditions can overlap, there are key differences. Hemorrhoids typically do not cause significant pain unless there is a thrombosis (clot formation) or if they become prolapsed. In contrast, conditions like anal fissures are often associated with sharp pain during and after bowel movements.
It’s also important to consider other factors that may contribute to your symptoms, such as diet, hydration, and bowel habits. A diet low in fiber can lead to constipation, straining during bowel movements, and subsequently, hemorrhoids. Increasing fiber intake, staying hydrated, and using stool softeners can help alleviate symptoms and prevent further complications.

In summary, while your symptoms may suggest internal hemorrhoids, it’s essential to monitor your condition closely. If the bleeding persists, or if you experience additional symptoms such as significant pain, changes in bowel habits, or weight loss, seek further medical evaluation. Early diagnosis and treatment are key to managing any underlying conditions effectively. Always consult with your healthcare provider for personalized advice and treatment options tailored to your specific situation.
