Blood in Stool: Causes, Concerns, and When to Seek Help

Blood in stool issue?

Hello doctor, I often have constipation issues, sometimes with hard stools and brown-colored stools.
Three years ago, I experienced fresh blood in my stool, but it resolved the next day.
Recently, I noticed fresh blood on my stool for the first time (but no bleeding).
After two days, I had a bowel movement and noticed more fresh blood afterward (more than before), and then during the third instance, the blood amount decreased (with some mucus).
I went to a nearby hospital to see a doctor, who diagnosed me with hemorrhoids.
After improving my diet and using topical medication along with stool softeners, I did not notice fresh blood the next day.
However, there was still a small amount of mucus-like discharge.
The next day, my stool was a darker brown color but still had a bit of mucus.
The doctor suggested that if I was concerned, I should get a colonoscopy.
My diet mainly consists of dumplings and noodles, and I sometimes enjoy spicy food, tea, and coffee.
I drink about 500 cc of plain water daily.
I want to know if this could be cancer! Additionally, my usual ear temperature is around 36.4-36.5°C, but recently it has been around 36.8-36.9°C, which has been quite worrying for me!

This situation likely indicates a higher possibility of hemorrhoidal bleeding.
As long as there is no further bleeding, it should not be a concern.
It is recommended to avoid constipation during this period and to shorten the time spent on bowel movements.
Warm sitz baths may help alleviate symptoms.
You can also purchase over-the-counter hemorrhoid suppositories and use stool softeners, but it is best not to take any medications indiscriminately.
If bleeding persists, it is advisable to consult a physician.
Although the likelihood of developing colorectal cancer at the age of 34 is not zero, it is generally considered low.
It is recommended to increase dietary fiber intake and maintain a healthy lifestyle.
Spicy, irritating, and greasy foods should be avoided.
If symptoms continue without improvement, you may ask a physician for medication or to undergo a colonoscopy.

Understanding blood in stool can be a concerning issue, and it’s important to approach it with a clear understanding of potential causes, implications, and when to seek medical help. Based on your description, it seems you have experienced a few episodes of blood in your stool, which can be alarming.
Firstly, the presence of blood in the stool can arise from various sources within the gastrointestinal tract. The most common causes include hemorrhoids (piles), anal fissures, diverticular disease, and gastrointestinal infections. In your case, since you have been diagnosed with hemorrhoids, this is likely the source of the blood you have observed. Hemorrhoids can cause bright red blood on the surface of the stool or on toilet paper, especially after straining during bowel movements, which is common in individuals with constipation.

Your history of constipation and hard stools can exacerbate hemorrhoids, leading to bleeding. The fact that you have also noted some mucus in your stool could be related to the irritation of the bowel lining due to straining or the presence of hemorrhoids. Mucus can also be a normal secretion from the intestines, but if it persists or is accompanied by other symptoms, it may warrant further investigation.

While hemorrhoids are a common and usually benign cause of rectal bleeding, it is essential to remain vigilant. The concern for colorectal cancer, especially given your symptoms and dietary habits, is valid. Risk factors for colorectal cancer include age, family history, a diet low in fiber, and a history of inflammatory bowel disease. Although your symptoms may be attributed to hemorrhoids, it is prudent to follow your doctor's advice regarding a colonoscopy, especially since you have had previous episodes of blood in your stool.

Regarding your dietary habits, it appears that your intake of fiber may be insufficient. A diet high in fiber can help prevent constipation and reduce the risk of hemorrhoids. Incorporating more fruits, vegetables, whole grains, and adequate hydration can significantly improve your bowel health. Drinking only 500 cc of water daily is quite low; increasing your fluid intake is crucial for softening stools and promoting regular bowel movements.

As for your body temperature, a slight increase to 36.8-36.9°C is generally not concerning unless accompanied by other symptoms such as fever, chills, or significant discomfort. It’s essential to monitor your overall health and any changes in your symptoms.

In summary, while hemorrhoids are a likely cause of your symptoms, it is crucial to remain proactive about your health. If you experience any of the following, seek medical attention promptly:
1. Persistent or worsening bleeding.

2. Changes in bowel habits, such as diarrhea or constipation lasting more than a few days.

3. Unexplained weight loss.

4. Severe abdominal pain.

5. Any new or unusual symptoms.

In conclusion, while your current symptoms may be manageable with dietary changes and treatment for hemorrhoids, a thorough evaluation through a colonoscopy is advisable to rule out any serious conditions, including colorectal cancer. Regular follow-ups with your healthcare provider will ensure that any changes in your condition are monitored and addressed appropriately.
