Bowel issues (patients with ulcerative colitis)


Hello Doctor: For a long time, I mistakenly believed I had internal hemorrhoids (I received treatment for it several times three years ago), which led to a delay in seeking medical attention.
Recently, I went to the hospital for an examination and was diagnosed with ulcerative colitis (proctology).
Currently, the doctor showed me a chart of inflammation severity (ranging from 0 to 3) and indicated that my inflammation level is around 1.5, with an inflamed length of about 7 to 8 centimeters.
(I have started taking mesalamine tablets for treatment.)
My main question concerns the "shape of my stool." I have never experienced this before, but over the past month, after switching from white rice to brown rice, I noticed that my stool initially retains its shape but begins to break apart slowly once it is in the toilet water.
Upon observing my stool, I noticed it contains a significant amount of fiber material, such as the bran layer from the brown rice.
Initially, I thought this was due to the brown rice.
However, after asking other family members, they do not experience this phenomenon, so I would like to ask you whether this observation is related to ulcerative colitis, or could it indicate that I might have another gastrointestinal condition?
P.S.
I have bowel movements 1 to 2 times a day, and the consistency of my stool is moderate.
Sometimes it is accompanied by mucus or blood (symptoms of colitis).
Thank you for your patient response.
I appreciate it!

Ulcerative colitis is an autoimmune disease in which the immune system attacks the intestinal mucosa, leading to ulcer formation.
Due to these mucosal ulcers, bleeding and mucus production can occur.
Additionally, inflammation of the intestines is common, resulting in loose stools.
If you have already been diagnosed with ulcerative colitis, it is likely that you have undergone a colonoscopy, which generally rules out other intestinal diseases.

Understanding bowel changes in patients with ulcerative colitis (UC) is crucial for both managing the condition and alleviating patient concerns. Ulcerative colitis is a chronic inflammatory bowel disease characterized by inflammation and ulceration of the colonic mucosa. This condition can lead to various gastrointestinal symptoms, including changes in bowel habits and stool consistency.

In your case, the changes in your stool shape and consistency, particularly the tendency for your stool to break apart in water, can indeed be related to your diagnosis of ulcerative colitis. The inflammation associated with UC can affect the normal function of the colon, leading to altered bowel movements. Patients with UC often experience symptoms such as diarrhea, rectal bleeding, and mucus in the stool, which can all contribute to changes in stool appearance.

The fact that you have recently switched to a diet that includes brown rice may also play a role in your bowel changes. Brown rice is high in fiber, which can affect stool consistency. While fiber is generally beneficial for digestive health, in the context of UC, it can sometimes exacerbate symptoms, especially during flare-ups. The presence of rice bran in your stool could indicate that your body is having difficulty fully digesting the fiber, which is not uncommon in individuals with inflammatory bowel diseases.
It’s important to note that while changes in stool consistency can be a symptom of ulcerative colitis, they can also be influenced by dietary changes. The fact that you are experiencing soft stools that sometimes contain mucus or blood is consistent with the symptoms of UC. The mucus is often a result of the inflamed colon producing excess mucus as a protective response, while blood can occur due to ulceration of the colonic mucosa.

Regarding your concerns about possibly having other gastrointestinal diseases, it’s reassuring to know that your diagnosis of ulcerative colitis has been confirmed through medical evaluation. While other conditions can cause similar symptoms, the specific findings from your colonoscopy and the presence of inflammation in your colon are indicative of UC.
To manage your condition effectively, it’s essential to maintain open communication with your healthcare provider. They can help you monitor your symptoms and adjust your treatment plan as needed. If you notice any significant changes in your symptoms, such as increased frequency of blood in your stool, severe abdominal pain, or persistent diarrhea, it’s crucial to seek medical advice promptly.

In summary, the changes in your bowel movements are likely related to your ulcerative colitis and possibly influenced by your dietary changes. Continuing your treatment with medications like mesalamine (the active ingredient in 阿腸克錠) is essential for controlling inflammation and preventing flare-ups. Regular follow-ups with your healthcare provider will help ensure that your condition is managed effectively and that any new symptoms are addressed promptly. Remember, managing ulcerative colitis is a journey, and with the right support and treatment, many patients can lead full and active lives.
