Left abdominal pain (to the left of the navel)


Hello, I recently visited a clinic due to lower back pain.
After an ultrasound, the doctor diagnosed me with kidney stones.
Following urine tests and X-rays, no issues were found, and my back pain resolved in about two days.
However, I then started experiencing intermittent dull pain in the left side of my abdomen (above and below the navel).
The pain is not very pronounced and feels somewhat crampy; I don't notice it unless I focus on it.
This has persisted for about two weeks.
I would like to ask the doctor if, given that there is no family history of colorectal cancer, I need to undergo a colonoscopy for this condition.

Dr. Yang Zhichao reply Gastroenterology and Hepatology


Hello Mr./Ms.
Shan, based on the symptoms you provided, the pain near the navel (upper left, lower left) is associated with the intestines.
It is also possible that referred pain from ureteral stones could occur in this area.
If you wish to arrange for an examination, an abdominal ultrasound can check for hydronephrosis, and a colonoscopy can assess for any lesions in the colon.
Of course, your risk of colorectal cancer is low.
Before scheduling these tests, it would be advisable to have an initial evaluation at a gastroenterology clinic.
Thank you for your inquiry, and Changhua Hospital cares about your health.

When considering whether to undergo a colonoscopy for left abdominal pain, several factors must be taken into account. Based on the symptoms you described, including intermittent, mild pain in the left abdominal area that has persisted for about two weeks, it is essential to evaluate the potential causes of your discomfort before deciding on the necessity of a colonoscopy.

Firstly, the left side of the abdomen houses several vital organs, including parts of the colon, the left kidney, and the ureter. Given your previous diagnosis of kidney stones, it is possible that the pain could be related to residual effects from that condition, especially if the pain is not severe and is intermittent. Kidney stones can sometimes cause referred pain to the abdomen, particularly if there is any irritation or inflammation in the urinary tract.

However, the nature of your pain—being mild and not constant—suggests that it may not be an urgent issue. The absence of a family history of colorectal cancer is also a positive factor, as family history can significantly increase the risk of developing such conditions. Nonetheless, it is crucial to consider other gastrointestinal issues that could be causing your symptoms, such as diverticulitis, irritable bowel syndrome (IBS), or even mild colitis.

A colonoscopy is a valuable diagnostic tool that allows for direct visualization of the colon and rectum. It can help identify conditions such as polyps, inflammation, or tumors. However, it is typically recommended when there are more concerning symptoms present, such as significant changes in bowel habits, unexplained weight loss, persistent abdominal pain, or the presence of blood in the stool. Since your symptoms do not seem to align with these more alarming signs, a colonoscopy may not be immediately necessary.

Before proceeding with a colonoscopy, it would be prudent to consult with a gastroenterologist who can perform a thorough evaluation of your symptoms. They may recommend starting with less invasive tests, such as abdominal ultrasound or CT scans, to rule out any structural abnormalities or other conditions that could be causing your pain. Additionally, they may suggest dietary modifications or lifestyle changes to see if your symptoms improve.

If your pain persists or worsens, or if you develop new symptoms such as changes in bowel habits, fever, or significant weight loss, it would then be advisable to reconsider the need for a colonoscopy. In the meantime, keeping a symptom diary, noting any correlations with food intake or activities, can provide valuable information to your healthcare provider.

In summary, while a colonoscopy is a useful diagnostic procedure, it may not be necessary at this stage given your mild symptoms and lack of alarming signs. A thorough evaluation by a gastroenterologist, along with appropriate imaging studies, may provide a clearer picture of your condition and guide further management. Always prioritize open communication with your healthcare provider to ensure that your concerns are addressed and that you receive the most appropriate care for your situation.
