Abdominal pain with rectal bleeding?


Hello Doctor: I have been experiencing some pain in my lower abdomen over the past few days, and I find it difficult to have a bowel movement.
This afternoon, I noticed blood in my stool; initially, there was only a small amount on the toilet paper, but by the evening, the toilet bowl was almost filled with bloody water.
My recent diet has been somewhat unhealthy, as I have been eating out while traveling, and due to the hot weather, I have been consuming a lot of cold drinks with very little water intake.
Could this be related to my symptoms? Thank you for your help.

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 also help alleviate symptoms.
You can purchase hemorrhoid suppositories at the pharmacy for use.
It is best not to take stool softeners indiscriminately.
At this age, increasing the intake of dietary fiber and fluids should be sufficient.
However, if bleeding persists, it is advisable to consult a physician for evaluation.

More Info


Abdominal pain accompanied by blood in the stool can be alarming and may indicate a variety of underlying health issues. Based on your description, it seems that you are experiencing discomfort in the lower abdomen, difficulty with bowel movements, and have noticed blood in your stool, which has progressed from a small amount on toilet paper to a significant amount in the toilet bowl. This situation warrants careful consideration and possibly immediate medical attention.

There are several potential causes for your symptoms. One common cause of abdominal pain and blood in the stool is hemorrhoids, which are swollen veins in the lower rectum and anus that can cause pain, itching, and bleeding, especially during bowel movements. Given that you mentioned difficulty in passing stool, straining during bowel movements could exacerbate hemorrhoids, leading to bleeding.

Another possibility is anal fissures, which are small tears in the lining of the anus that can occur due to hard or large stools. These can be quite painful and may also result in bleeding. Both hemorrhoids and anal fissures are often associated with constipation, which can be influenced by dietary habits, such as a low fiber intake and inadequate hydration.

In more serious cases, blood in the stool can indicate gastrointestinal conditions such as diverticulitis, inflammatory bowel disease (IBD) like Crohn's disease or ulcerative colitis, or even colorectal cancer, especially if you have a family history of these conditions or if you are experiencing other symptoms such as weight loss, fever, or persistent changes in bowel habits.

Your recent dietary changes, including eating out and consuming less water, may have contributed to constipation, which can lead to the issues mentioned above. A diet low in fiber can result in harder stools, making bowel movements more difficult and painful. Additionally, consuming cold beverages in hot weather can sometimes lead to gastrointestinal discomfort for some individuals, although this is less common.

Given the progression of your symptoms, it is crucial to seek medical attention promptly. A healthcare provider will likely perform a physical examination and may recommend diagnostic tests such as a stool test, colonoscopy, or imaging studies to determine the exact cause of your symptoms. It is essential to provide your doctor with a complete history of your symptoms, dietary habits, and any other relevant health information.

In the meantime, consider increasing your fluid intake and incorporating more fiber-rich foods into your diet, such as fruits, vegetables, whole grains, and legumes. This can help alleviate constipation and may reduce the risk of further complications. However, do not delay seeking professional medical advice, as blood in the stool can be a sign of a serious condition that requires immediate attention.
In summary, while there are several potential causes for your symptoms, including hemorrhoids, anal fissures, or more serious gastrointestinal conditions, it is vital to consult with a healthcare professional to obtain an accurate diagnosis and appropriate treatment. Your health and well-being should always be the top priority.
