Blood in Stool: Causes and Concerns for Your Health

Blood in stool, blood on toilet paper?

Doctor, I noticed blood on the toilet paper when I wiped after having a bowel movement the night before last, and there was also a small amount of blood at the end of the stool (both were bright red).
The next day, there was no more blood, but sometimes the stool seems to have a little blood clots, and the stool is sometimes formed and sometimes not.
I have high blood pressure and am on medication, and sometimes I feel a bit dizzy.
Recently, I started controlling my weight and changed my diet; I went from nearly 81 kg in mid-March to about 73 kg today in mid-June.
Is this normal? Could you please help me understand what my condition might be? Thank you.

Rectal bleeding is considered an abnormal symptom and can range from common conditions like hemorrhoids to more serious gastrointestinal diseases.
Based on your description, the likelihood of hemorrhoidal bleeding is highest.
If the bleeding persists without improvement or if there are other gastrointestinal symptoms, it is advisable to visit a hospital's surgical or gastroenterology department for further evaluation.
If weight loss is a result of dietary control, it can be monitored; however, similar to rectal bleeding, if the weight continues to decrease, it is recommended to seek medical evaluation.

More Info

When you notice blood in your stool, it can understandably cause concern. The presence of bright red blood on toilet paper or mixed with stool can indicate several potential issues, some of which may require medical attention. Let's break down the possible causes and what you should consider regarding your health.

Possible Causes of Blood in Stool
1. Hemorrhoids: One of the most common causes of bright red blood in the stool is hemorrhoids. These are swollen veins in the lower rectum or anus that can bleed during bowel movements, especially if you are straining or have constipation.

2. Anal Fissures: Small tears in the lining of the anus can also cause bleeding. These are often painful and can occur due to passing hard stools.

3. Diverticular Disease: Diverticulosis, which involves small pouches forming in the colon wall, can lead to diverticulitis, where these pouches become inflamed or infected, potentially causing bleeding.

4. Colorectal Polyps or Cancer: While less common, polyps (growths on the colon lining) or colorectal cancer can cause bleeding. This is particularly a concern if you have a family history of colorectal cancer or if you are over the age of 50.

5. Gastrointestinal Infections: Certain infections can lead to inflammation and bleeding in the gastrointestinal tract.

6. Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause inflammation and bleeding in the intestines.

Your Symptoms and Health Concerns
Given that you have high blood pressure and have recently changed your diet for weight control, it's important to consider how these factors might interact with your gastrointestinal health. Rapid weight loss can sometimes lead to changes in bowel habits, including the consistency of stools. If your stools are sometimes formed and sometimes not, this could indicate a change in your diet or hydration levels.

The fact that you experienced blood only once and it has not recurred is somewhat reassuring, but it does not eliminate the need for caution. The dizziness you mentioned could be related to your blood pressure medication, dietary changes, or even dehydration, especially if you are consuming less fiber or fluids during your weight loss efforts.

Recommendations
1. Monitor Your Symptoms: Keep an eye on your bowel movements. If the blood reappears, if you experience pain, or if you notice other symptoms like significant changes in bowel habits, weight loss, or abdominal pain, seek medical attention promptly.

2. Consult a Healthcare Provider: Given your history of high blood pressure and the recent changes in your diet, it would be wise to consult with a healthcare provider. They may recommend a physical examination, blood tests, or even a colonoscopy to rule out any serious conditions.

3. Dietary Adjustments: Ensure you are consuming a balanced diet rich in fiber to help maintain regular bowel movements and prevent constipation, which can exacerbate hemorrhoids and fissures.

4. Hydration: Stay well-hydrated, especially if you are changing your diet and exercising more.

5. Medication Review: Discuss your current medications with your doctor, especially if you are experiencing dizziness. Adjustments may be necessary based on your blood pressure readings and overall health.

Conclusion
While blood in the stool can be alarming, many causes are benign, such as hemorrhoids or anal fissures. However, due to your medical history and the changes you are experiencing, it is crucial to consult with a healthcare professional to ensure that any underlying issues are addressed. Early detection and intervention can significantly improve outcomes, especially concerning gastrointestinal health.
