Right Lower Abdominal Pain: Possible Causes and Concerns - Gastroenterology and Hepatology

Recently, I have been experiencing pain in the lower right abdomen?


Due to living off-campus during university and eating out for all meals, I underwent a colonoscopy at a major hospital two months ago, where an adenomatous polyp was removed and confirmed to be benign.
However, recently I've been experiencing pain in my lower right abdomen upon waking up.
The pain is not constant but occurs in episodes lasting 10-15 minutes, and it happens similarly after using the restroom.
Is it possible that the colonoscopy missed some polyps? Additionally, my stool is formed at the beginning but becomes mushy afterward, often containing small pieces resembling diced carrots, even though I haven't eaten any red foods.
I'm very concerned that this might indicate gastrointestinal bleeding.
If there are no issues with my intestines, could it be related to my stomach or rectum? I would appreciate any advice from a doctor.
Thank you.

More Info


Understanding right lower abdominal pain can be quite complex, especially given your medical history and recent symptoms. The right lower abdomen houses several vital organs, including parts of the intestines, the appendix, and in females, the ovaries and fallopian tubes. Therefore, pain in this area can arise from various causes, some of which may require immediate medical attention.

Given your history of adenomatous polyps that were removed and deemed benign, it is understandable that you are concerned about the possibility of undetected polyps or other gastrointestinal issues. While it is possible that the pain you are experiencing could be related to your previous colonoscopy, it is essential to consider other potential causes as well.

1. Gastrointestinal Causes:
- Irritable Bowel Syndrome (IBS): This common condition can cause intermittent abdominal pain, changes in bowel habits, and discomfort after eating. Symptoms can vary widely among individuals.

- Diverticulitis: Inflammation or infection of diverticula (small pouches that can form in the walls of the intestines) can lead to localized pain, often in the lower left abdomen, but can also present on the right side.

- Appendicitis: Although typically presenting with more constant pain, appendicitis can start as intermittent pain in the right lower abdomen, especially if the inflammation is mild.

- Bowel Obstruction: This can occur due to scar tissue from previous surgeries or other reasons, leading to cramping pain and changes in bowel movements.

2. Non-Gastrointestinal Causes:
- Gynecological Issues: In females, conditions such as ovarian cysts, ectopic pregnancy, or pelvic inflammatory disease can cause right-sided abdominal pain.

- Urinary Tract Issues: Kidney stones or infections can also manifest as abdominal pain, particularly if they are located on the right side.

Regarding your bowel movements, the presence of a "stringy" stool followed by a more mushy consistency can be indicative of several things. It may suggest a dietary issue, such as insufficient fiber intake, or it could be a sign of gastrointestinal distress. The small, carrot-like pieces you mentioned could be undigested food particles or, in some cases, could indicate mucus or other substances in the stool, which might warrant further investigation.

Recommendations:
1. Follow-Up with Your Doctor: Given your symptoms and medical history, it is crucial to consult with your healthcare provider. They may recommend imaging studies, such as an abdominal ultrasound or CT scan, to evaluate for any structural issues or abnormalities in the gastrointestinal tract.

2. Monitor Symptoms: Keep a detailed record of your symptoms, including the frequency and intensity of the pain, any associated symptoms (like fever, nausea, changes in appetite), and your bowel habits. This information will be valuable for your healthcare provider.

3. Dietary Considerations: Consider adjusting your diet to include more fiber, which can help regulate bowel movements. Staying hydrated is also essential for digestive health.

4. Emergency Symptoms: If you experience severe pain, fever, vomiting, or blood in your stool, seek medical attention immediately, as these could be signs of a more serious condition.

In conclusion, while your previous colonoscopy findings are reassuring, the symptoms you are experiencing warrant further evaluation to rule out any potential complications or new issues. Your healthcare provider will be best positioned to guide you through the next steps based on a thorough assessment of your condition.
