Bowel issues


Hello doctor, I have been experiencing diarrhea for quite some time now.
My stomach sometimes hurts and sometimes it doesn't, but my bowel movements are always loose, almost every day.
Sometimes I feel the urge to go to the bathroom right after eating, which often happens after breakfast and dinner.
The color of my stool looks normal.
Could this be a sign of a tumor in the rectum, or could it be irritable bowel syndrome?

Dr. Ke Fangxu reply Surgery


The likelihood of developing colorectal cancer at the age of 19 is not zero, but generally speaking, it is very, very low.
Based on your description, it seems more like irritable bowel syndrome (IBS).
It is recommended to follow a light diet and maintain a good lifestyle.
Spicy, irritating, and greasy foods should be avoided.
Increasing the intake of dietary fiber can also be helpful.
If symptoms persist without improvement, you may want to consult a physician for medication or to undergo a colonoscopy.

More Info


Diarrhea is a common gastrointestinal issue that can arise from various causes, and understanding its symptoms and when to seek medical help is crucial for effective management. Based on your description, it seems you have been experiencing persistent diarrhea accompanied by occasional abdominal pain. This situation can be concerning, especially if it has been ongoing for an extended period.


Causes of Diarrhea
Diarrhea can be classified into several types based on its underlying causes:
1. Infectious Causes: This includes viral infections (like norovirus or rotavirus), bacterial infections (such as E. coli or Salmonella), and parasitic infections (like Giardia). These infections can lead to inflammation of the intestines, resulting in diarrhea.

2. Non-Infectious Causes: Conditions such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), celiac disease, and food intolerances (like lactose intolerance) can also cause chronic diarrhea. IBS, in particular, is characterized by a combination of symptoms including abdominal pain, bloating, and changes in bowel habits.

3. Medications: Certain medications, especially antibiotics, can disrupt the normal gut flora and lead to diarrhea. Other medications, such as those used for cancer treatment or magnesium-containing antacids, can also have this side effect.

4. Dietary Factors: High intake of certain foods, especially those rich in sugar or fat, can lead to diarrhea. Additionally, consuming artificial sweeteners like sorbitol can cause gastrointestinal upset in some individuals.

5. Stress and Anxiety: Psychological factors can also play a significant role in gastrointestinal health. Stress and anxiety can exacerbate symptoms of IBS and lead to diarrhea.


Symptoms to Monitor
In addition to diarrhea, you mentioned experiencing abdominal pain and urgency to use the restroom after meals. It's important to monitor the following symptoms:
- Frequency and Consistency: How often are you experiencing diarrhea? Is it watery, or is there any presence of blood or mucus?
- Associated Symptoms: Are you experiencing any fever, weight loss, or dehydration symptoms (such as dry mouth, dizziness, or decreased urination)?
- Duration: If diarrhea persists for more than two days, it is advisable to seek medical attention.


When to Seek Help
You should consider seeking medical help if you experience any of the following:
- Severe Abdominal Pain: If the pain is intense and persistent, it could indicate a more serious condition.

- Blood in Stool: The presence of blood or black, tarry stools can be a sign of gastrointestinal bleeding and requires immediate evaluation.

- Signs of Dehydration: If you notice symptoms like excessive thirst, dry mouth, or decreased urination, these could indicate dehydration.

- Persistent Symptoms: If diarrhea lasts more than 48 hours without improvement, or if you have recurrent episodes, it’s important to consult a healthcare provider.


Potential Concerns
Regarding your concerns about rectal tumors or conditions like IBS, it’s essential to undergo a thorough evaluation by a healthcare professional. They may recommend diagnostic tests such as stool studies, blood tests, or imaging studies to rule out serious conditions. A colonoscopy may also be suggested if there are concerns about structural abnormalities in the colon.


Conclusion
In summary, while diarrhea can often be benign and self-limiting, persistent symptoms warrant a medical evaluation to rule out serious underlying conditions. Keeping a symptom diary, including food intake and stress levels, can be helpful for your healthcare provider in determining the cause of your symptoms. Remember, early intervention can lead to better outcomes, so don’t hesitate to seek help if your symptoms persist or worsen.
