Intermittent abdominal pain?


Recently, I've been experiencing sudden cramping pain in my lower abdomen that lasts for a few seconds and then disappears.
Sometimes I feel a strong urge to have a bowel movement, but when I get to the toilet, I can't go.
It feels like there's something in my rectum, but I'm not constipated.
My stool has changed from normal to a mix of normal and diarrhea, and the gas I pass is mostly small and foul-smelling.
Am I at risk for colon cancer?

Hello Benson, based on your age, it is less likely to be colorectal cancer.
If you are concerned, you can consult a gastroenterologist for further evaluation and arrange for tests.
Thank you for your question.

Sudden abdominal pain can be alarming, especially when accompanied by changes in bowel habits and other gastrointestinal symptoms. Your description of experiencing sudden cramping pain in the lower abdomen, difficulty with bowel movements, and changes in stool consistency raises several considerations regarding your gut health.

Firstly, it’s important to understand that abdominal pain can arise from a variety of causes, ranging from benign to serious conditions. The sudden cramping you experience could be related to gastrointestinal issues such as irritable bowel syndrome (IBS), which is characterized by abdominal pain and altered bowel habits, including diarrhea and constipation. Stress and anxiety can exacerbate IBS symptoms, leading to cramping and urgency without the ability to pass stool.

Another possibility is that you may be experiencing a form of intestinal obstruction or a functional bowel disorder. This could explain the sensation of having something in your rectum and the difficulty in passing stool despite not being constipated. Conditions like fecal impaction can occur even when bowel movements seem normal, especially if there are inconsistencies in stool consistency.

The foul-smelling gas you mentioned could also indicate a change in your gut flora or diet, which can affect digestion and gas production. Foods that are high in fiber or certain carbohydrates can lead to increased gas production, particularly if your body is not used to them.

While the symptoms you describe can be concerning, especially the fear of serious conditions like colorectal cancer, it’s essential to remember that many gastrointestinal issues are not cancer-related. Colorectal cancer typically presents with more persistent symptoms, such as significant changes in bowel habits, blood in the stool, unexplained weight loss, or persistent abdominal discomfort. However, it is crucial to take your symptoms seriously and consult with a healthcare professional for a thorough evaluation.

Given your symptoms, I recommend the following steps:
1. Consult a Healthcare Provider: Schedule an appointment with a gastroenterologist or your primary care physician. They may recommend tests such as a colonoscopy, imaging studies, or stool tests to rule out serious conditions and to better understand your symptoms.

2. Keep a Symptom Diary: Document your symptoms, including the frequency and intensity of abdominal pain, changes in bowel habits, diet, and any other relevant factors. This information can be invaluable for your healthcare provider in diagnosing your condition.

3. Dietary Considerations: Pay attention to your diet. Certain foods may trigger your symptoms. A diet low in FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) can sometimes help alleviate symptoms of IBS.

4. Stress Management: Since stress can exacerbate gastrointestinal symptoms, consider incorporating stress-reducing activities into your routine, such as exercise, meditation, or yoga.

5. Hydration and Fiber: Ensure you are adequately hydrated and consuming enough fiber to support healthy bowel movements. However, if you suspect that fiber is causing your symptoms, consider adjusting your intake gradually.

In summary, while your symptoms can be concerning, they are not necessarily indicative of colorectal cancer. A thorough evaluation by a healthcare professional is essential to determine the underlying cause of your abdominal pain and changes in bowel habits. Early intervention and appropriate management can significantly improve your quality of life and gut health.
