Narrowing of the stool?


Hello Doctor: I am 25 years old, and I have had normal bowel movements since childhood, typically every 1-2 days.
However, for the past six months, I have been experiencing soft stools that have persisted for about 2-3 months, and my stools have not been well-formed.
Recently, in the past month or two, I have noticed that my stools have become narrower, about 2-3 fingers wide.
After feeling the urge to defecate, I am unable to empty my bowels as quickly as before, and the softer stools tend to stick to the toilet.
The color is normal, but I have noticed an increase in the amount of stool left on my anus after wiping.
A few hours after wiping, I feel itching in the anal area and find traces of stool color upon wiping.
I have to exert effort during bowel movements, but the stools are soft.
There is also a lot of gas released before and after defecation.
I am very concerned about the possibility of colorectal cancer.
Could you please advise me on what tests I should undergo next or what I should pay attention to? Thank you.

When it comes to changes in bowel habits, it’s understandable to feel concerned, especially when you notice significant alterations in the consistency, shape, and frequency of your stools. Based on your description, it seems you have experienced a shift from normal bowel movements to softer stools that are difficult to pass, along with a change in shape and an increase in the sensation of needing to wipe after a bowel movement. While these symptoms can be alarming, they are not necessarily indicative of a serious condition like colorectal cancer, especially at your age. However, it’s important to take these changes seriously and consult a healthcare professional for a thorough evaluation.

Firstly, let's break down some of the symptoms you've mentioned:
1. Soft stools: This can be caused by a variety of factors, including dietary changes, increased fiber intake, or even stress. Soft stools are often a sign of a diet that may be high in fats or sugars and low in fiber. It’s essential to assess your diet and consider whether you’ve made any recent changes that could contribute to this.

2. Narrow stools: The change in the width of your stools can be concerning. Narrow stools can sometimes indicate a blockage in the intestines or changes in the colon. However, they can also be a result of dietary factors or temporary changes in bowel habits.

3. Increased gas and the sensation of incomplete evacuation: These symptoms can be associated with various gastrointestinal issues, including irritable bowel syndrome (IBS), which is characterized by a combination of abdominal pain and altered bowel habits. Stress and anxiety can exacerbate these symptoms.

4. Itching and residual stool: The sensation of itching and the feeling of residual stool can be related to hygiene issues or irritation in the anal area, which can occur with softer stools. It’s important to maintain good hygiene and consider using gentle, unscented wipes to avoid irritation.

Given these symptoms, here are some recommendations on what to do next:
1. Dietary Review: Start by reviewing your diet. Ensure you are consuming adequate fiber (fruits, vegetables, whole grains) and staying hydrated. Sometimes, increasing fiber too quickly can lead to gas and bloating, so make changes gradually.

2. Monitor Symptoms: Keep a diary of your bowel habits, noting the consistency, frequency, and any associated symptoms (like pain, bloating, or changes in appetite). This information can be very helpful for your healthcare provider.

3. Consult a Healthcare Professional: It’s crucial to see a doctor, preferably a gastroenterologist, who can perform a thorough evaluation. They may recommend tests such as a colonoscopy, especially given your concerns about colorectal cancer. While the likelihood of cancer at your age is low, it’s always better to rule out serious conditions.

4. Consider Stress and Mental Health: Since stress can significantly impact digestive health, consider whether you’ve been experiencing increased stress or anxiety. Techniques such as mindfulness, yoga, or talking to a mental health professional can be beneficial.

5. Follow-Up: If your symptoms persist or worsen, follow up with your healthcare provider. They may suggest further testing or dietary adjustments based on your initial evaluation.

In summary, while your symptoms are concerning, they are not definitive indicators of a serious condition like colorectal cancer, especially given your age. However, it’s essential to take them seriously and seek medical advice to ensure proper diagnosis and treatment. Remember, early intervention can often lead to better outcomes, so don’t hesitate to reach out to a healthcare professional.
