Blood in Stool: Causes and When to Seek Help

Blood in the stool?

Doctor, a few days ago I experienced pain when pressing on the lower left side of my abdomen.
After visiting the clinic and taking anti-inflammatory and digestive aid medications for a few days, I felt some improvement.
However, today I noticed blood streaks in my stool, which appeared slightly membranous and not completely liquid.
Since the stool was larger, it was somewhat difficult to pass, and I also felt some pain in my anus.
I'm unsure how to distinguish whether this is a tear in the anus or an internal issue.

Based on your description, it seems more like Irritable Bowel Syndrome (IBS).
It is recommended to start with a light diet and maintain a good daily routine.
If symptoms persist without improvement, you may consult a physician for medication.
The issue of anal pain is likely due to an anal fissure, with typical symptoms including pain during bowel movements accompanied by slight bleeding.
The primary cause of anal fissures is usually hard stools; however, diarrhea, frequent bowel movements, or prolonged straining can also lead to fissures.
It is advisable to improve bowel habits and take warm sitz baths to alleviate symptoms.
Topical ointments and suppositories can also be used for treatment.
If symptoms do not improve after one week, you should consult a physician for further evaluation to identify the underlying issue.

More Info

When it comes to blood in the stool, it can be a concerning symptom that warrants careful evaluation. The presence of blood, even in small amounts, can indicate a variety of conditions, some of which may require medical attention. In your case, you mentioned experiencing pain in the lower left abdomen, which improved with anti-inflammatory and digestive medications, but now you are noticing blood streaks in your stool, accompanied by some discomfort during bowel movements.

Possible Causes of Blood in Stool
1. Hemorrhoids: One of the most common causes of blood in the stool, especially if the blood is bright red and appears on the surface of the stool or on toilet paper. Hemorrhoids can cause pain and discomfort, particularly during bowel movements.

2. Anal Fissures: These are small tears in the lining of the anus, often caused by passing large or hard stools. Symptoms include sharp pain during and after bowel movements, and you may notice bright red blood.

3. Diverticular Disease: Diverticulosis, which involves the formation of small pouches in the colon wall, can lead to diverticulitis if these pouches become inflamed. This condition can cause abdominal pain and changes in bowel habits, including blood in the stool.

4. Gastrointestinal Bleeding: More serious conditions, such as ulcers, inflammatory bowel disease (IBD), or colorectal cancer, can also cause blood in the stool. These conditions may present with additional symptoms such as weight loss, changes in bowel habits, or persistent abdominal pain.

5. Infections: Certain gastrointestinal infections can lead to bloody diarrhea, often accompanied by other symptoms like fever and abdominal cramping.

When to Seek Medical Help
Given your symptoms, it is advisable to seek medical attention, especially if:
- The blood in your stool persists or increases in amount.

- You experience significant pain or discomfort.

- You notice other symptoms such as fever, weight loss, or changes in appetite.

- You have a history of gastrointestinal issues or family history of colorectal cancer.

Diagnostic Approach
A healthcare provider may recommend several diagnostic tests to determine the cause of the bleeding, including:
- Physical Examination: A thorough examination, including a digital rectal exam, can help identify hemorrhoids or fissures.

- Stool Tests: To check for infections or blood.

- Colonoscopy: This procedure allows the doctor to visualize the inside of the colon and rectum, helping to identify any abnormalities.

- Imaging Studies: In some cases, imaging studies like a CT scan may be necessary to evaluate the abdominal organs.

Conclusion
While minor issues like hemorrhoids or anal fissures are common and often manageable, the presence of blood in the stool should not be ignored. It is essential to consult with a healthcare professional who can provide a proper diagnosis and treatment plan based on your specific situation. Early intervention can lead to better outcomes, especially if a more serious condition is present. Please take care of your health and seek the necessary medical advice promptly.
