Abdominal pain with changes in bowel habits?


Hello, doctor.
About a month ago, I suddenly experienced severe pain in my lower abdomen, which comes in waves.
Whenever I have these cramps, I feel the urge to have a bowel movement.
I went to a nearby clinic for treatment and also visited a hospital, but they diagnosed it as a gastrointestinal virus.
Recently, my lower abdomen continues to hurt, and sometimes I pass stool that is matcha-colored; otherwise, I have diarrhea (which is yellow).
I constantly feel the urge to go, but it feels like I can't empty my bowels completely, and I also have persistent flatulence.
Additionally, after eating carrots yesterday, my stool today looks like the carrots themselves, suggesting they were not digested properly.
About six months ago, I went to see a doctor due to fresh blood in my stool, but I have seen less blood since then.
Could this indicate a tumor in my colon or possibly colon cancer? I'm really worried and scared.

More Info


Abdominal pain and changes in bowel habits can be concerning symptoms that warrant careful evaluation. Based on your description, it seems that you have been experiencing significant discomfort in your lower abdomen, accompanied by changes in your stool consistency and color, as well as an ongoing sense of incomplete evacuation. These symptoms can be indicative of several gastrointestinal issues, and it is important to approach them with a thorough understanding.

Firstly, the intermittent sharp pain you are experiencing could be related to various gastrointestinal conditions. Common causes of abdominal pain include irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), or even gastrointestinal infections. IBS is characterized by abdominal pain associated with changes in bowel habits, such as diarrhea or constipation, and can often be triggered by stress or certain foods. On the other hand, IBD, which includes conditions like Crohn's disease and ulcerative colitis, involves inflammation of the gastrointestinal tract and can lead to more severe symptoms, including persistent abdominal pain, diarrhea, and sometimes blood in the stool.

The presence of "matcha-colored" stool and the fact that you are experiencing diarrhea could suggest a disruption in your digestive process. The color of stool can vary based on diet, but green stool can sometimes indicate that food is moving too quickly through the intestines, preventing proper absorption. The yellow stool you mentioned during episodes of diarrhea may indicate a malabsorption issue or a reaction to certain foods. Additionally, the fact that you are seeing undigested food, such as carrots, in your stool suggests that your body may not be breaking down food properly, which could be due to a variety of factors, including enzyme deficiencies or gastrointestinal motility issues.

Your previous experience with fresh blood in your stool is particularly concerning. While it is reassuring that you have seen less blood recently, any history of rectal bleeding should be taken seriously, as it can be a sign of conditions ranging from hemorrhoids to more serious issues like polyps or colorectal cancer. Given your family history of colorectal cancer, it is crucial to discuss these symptoms with a healthcare provider who can evaluate your risk factors and possibly recommend a colonoscopy for further investigation.

In terms of management, it is essential to maintain a balanced diet rich in fiber, which can help regulate bowel movements and improve overall digestive health. Staying hydrated is also important, as it can aid in digestion and prevent constipation. However, if dietary changes and over-the-counter remedies do not alleviate your symptoms, it is advisable to seek further medical evaluation.

Given the complexity of your symptoms and the potential for serious underlying conditions, I strongly recommend that you consult with a gastroenterologist. They can perform a comprehensive assessment, including a detailed history, physical examination, and possibly imaging studies or endoscopic procedures, to determine the cause of your symptoms. It is important to address these concerns promptly to ensure appropriate management and peace of mind.

In summary, while your symptoms may be related to functional gastrointestinal disorders, the possibility of more serious conditions cannot be overlooked. Seeking specialized medical advice will provide you with the best chance of obtaining a clear diagnosis and effective treatment plan. Remember, it is always better to err on the side of caution when it comes to your health.
