I'm not sure if it's irritable bowel syndrome (IBS)?


Hello Doctor, I would like to ask about my condition.
For the past few days, I have been feeling the urge to pass gas but have been unable to do so.
This morning, I suddenly experienced intermittent cramping in my abdomen, and it wasn't until I sat on the toilet that I was able to have a bowel movement.
Initially, my stool was thin, and then it turned into diarrhea.
My abdomen now feels bloated, I still have the urge to pass gas but can't, and my stomach is making noises.
I want to ask you, Doctor, because I had a gastroscopy in May of this year, and the doctor said there were no issues, suggesting that my symptoms are more indicative of irritable bowel syndrome.
However, I am still quite worried about the possibility of colon cancer, as I have anxiety and health anxiety issues.
Please help me analyze my situation based on what I have described.
Thank you.

More Info


Based on your symptoms and previous medical evaluations, it seems that you may be experiencing issues related to Irritable Bowel Syndrome (IBS). IBS is a common gastrointestinal disorder characterized by a combination of symptoms, including abdominal pain, bloating, gas, and changes in bowel habits, such as diarrhea or constipation. Your description of experiencing bloating, gas, and alternating bowel movements aligns with the typical presentation of IBS.

The fact that you recently underwent a colonoscopy and were told that there were no significant issues is reassuring. This suggests that more serious conditions, such as colorectal cancer, are less likely, especially given your age and the absence of alarming symptoms. However, it is understandable that you may still have concerns, particularly given your anxiety and health-related worries.

The symptoms you describe—such as the inability to pass gas, abdominal cramping, and changes in stool consistency—are common in individuals with IBS. The presence of thin stools followed by diarrhea can indicate that your intestines are reacting to certain triggers, which can include stress, dietary changes, or specific foods. Stress and anxiety are known to exacerbate IBS symptoms, and it’s important to manage these factors as they can significantly impact your gastrointestinal health.

To address your concerns and improve your symptoms, consider the following recommendations:
1. Dietary Adjustments: Keeping a food diary can help identify any foods that may trigger your symptoms. Common culprits include dairy products, gluten, high-fat foods, and certain carbohydrates known as FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols). A low-FODMAP diet may be beneficial for some individuals with IBS.

2. Regular Eating Schedule: Try to maintain a regular eating schedule and avoid skipping meals. Eating smaller, more frequent meals can help reduce bloating and discomfort.

3. Hydration: Ensure you are drinking enough water throughout the day, as proper hydration can aid digestion and help prevent constipation.

4. Physical Activity: Regular exercise can help improve bowel function and reduce stress levels. Aim for at least 30 minutes of moderate exercise most days of the week.

5. Stress Management: Since anxiety can exacerbate IBS symptoms, consider incorporating stress-reduction techniques into your routine. Practices such as mindfulness, yoga, meditation, or deep-breathing exercises can be beneficial.

6. Medications: If your symptoms persist, discuss with your healthcare provider the possibility of medications that can help manage IBS symptoms. Options may include antispasmodics for cramping, laxatives for constipation, or medications specifically designed for IBS.

7. Follow-Up: Since you have a history of anxiety and health concerns, it may be helpful to have regular follow-ups with your healthcare provider to monitor your symptoms and adjust your management plan as needed.

In conclusion, while your symptoms are concerning, they are more indicative of IBS rather than a serious condition like colorectal cancer, especially given your recent colonoscopy results. However, if you notice any alarming changes, such as blood in your stool, significant weight loss, or persistent pain, it is crucial to seek medical attention promptly. Remember that managing IBS often requires a multifaceted approach, including dietary changes, stress management, and possibly medication.
