Rectal bleeding


Last Friday, I had four bowel movements in one day.
The first stool was somewhat hard, the second was similar to diarrhea, with all the stool resembling scrambled eggs, and there was also a formed stool.
The water and stool had blood in it, which was bright red.
The third bowel movement had no blood, and the last one was similar to the second.
The bowel movements themselves were not painful, but I do have a hemorrhoid.
After that, I had no urge to have a bowel movement for three consecutive days, but I did pass stool during those days, although it was only a small pellet or a small amount of ribbon-like stool.
Again, the bowel movements were not painful.
What could be wrong with me?

Understanding blood in stool can be concerning, and it’s important to consider various factors that could contribute to this symptom. Based on your description, it seems that you experienced a mix of hard stools and diarrhea, along with the presence of bright red blood in your stool. Here are some potential causes and considerations regarding your situation.

1. Hemorrhoids: Given that you mentioned having a hemorrhoid, this could be a significant factor. Hemorrhoids are swollen veins in the lower rectum and anus that can cause bleeding, especially during bowel movements. The blood is often bright red, indicating that it is fresh and likely coming from the lower gastrointestinal tract. Straining during bowel movements, which can occur with hard stools, can exacerbate hemorrhoids and lead to bleeding.

2. Anal Fissures: Another possibility is the presence of anal fissures, which are small tears in the lining of the anus that can occur due to passing hard stools. These can also cause bright red blood and may be accompanied by pain during bowel movements.

3. Diverticular Disease: Diverticulosis, a condition where small pouches form in the colon wall, can also lead to bleeding. While this is more common in older adults, it can occur in younger individuals as well. If diverticulitis develops (inflammation of these pouches), it can lead to more severe symptoms.

4. Gastrointestinal Infections: The presence of diarrhea, especially if it is watery and resembles "egg drop soup," could indicate an infection or inflammation in the gastrointestinal tract. Infections can lead to bloody diarrhea, and it’s essential to consider any recent dietary changes or exposure to contaminated food or water.

5. Colorectal Polyps or Cancer: While less likely given your age and the description of your symptoms, it’s important to be aware that polyps or colorectal cancer can also present with blood in the stool. This is particularly a concern if you have a family history of colorectal issues or if the bleeding persists.

6. Dietary Factors: Sometimes, certain foods can cause gastrointestinal irritation or bleeding. Spicy foods, alcohol, or foods that you may be intolerant to could lead to symptoms like diarrhea and blood in the stool.

Given that you experienced a mix of hard stools and diarrhea, along with the presence of blood, it is crucial to monitor your symptoms closely. If the bleeding continues, worsens, or if you experience additional symptoms such as severe abdominal pain, fever, or significant changes in your bowel habits, it is essential to seek medical attention promptly. A healthcare provider may recommend a physical examination, possibly including a rectal exam, and may suggest further diagnostic tests such as a colonoscopy to evaluate the source of the bleeding.

In the meantime, consider increasing your fiber intake to help regulate your bowel movements and prevent straining. Staying hydrated is also important, especially if you have experienced diarrhea. Over-the-counter treatments for hemorrhoids may provide some relief, but it’s best to consult with a healthcare provider for a tailored approach to your symptoms.

In summary, while hemorrhoids and anal fissures are common causes of bright red blood in the stool, it is essential to consider other potential causes and to seek medical advice if symptoms persist or worsen. Your health and well-being are paramount, and timely intervention can help address any underlying issues effectively.
