Abdominal Pain: Is It Stomach or Colon Issues? - Gastroenterology and Hepatology

I can't distinguish between the stomach and the colon?

Hello doctor, I started experiencing pain in my upper left abdomen in early April this year.
I visited a gastroenterology clinic five times and underwent an upper endoscopy.
The doctor said everything was normal and there was no Helicobacter pylori infection.
Each time, the doctor prescribed stool softeners and some gastric medications.
As of May 18, my stools have been consistently thin, and I still experience pain in my upper left abdomen.
I am now very worried that it might be colon cancer and am unsure if I should undergo a colonoscopy.
I am quite anxious about whether this is a colon issue.

Hello, sir.
You can start by checking for occult blood in the stool; there's no need to worry too much.
If the result is positive, then further examination of the colon will be necessary.

Abdominal pain can be a complex and challenging symptom to diagnose, especially when it persists for an extended period, as in your case. The left upper abdominal pain you've been experiencing since early April, despite multiple consultations and tests, raises several considerations.
Firstly, it's important to understand that abdominal pain can originate from various organs, including the stomach, intestines, liver, gallbladder, pancreas, and even the muscles and nerves in the abdominal wall. Given that you've already undergone an upper gastrointestinal endoscopy (gastroscopy) and tests for Helicobacter pylori, which returned normal results, we can rule out some common gastrointestinal issues such as peptic ulcers or gastritis.

The fact that you are experiencing changes in your bowel habits, specifically that your stools have become thinner, could indicate a functional gastrointestinal disorder. One possibility is irritable bowel syndrome (IBS), which can cause abdominal pain, bloating, and changes in bowel habits without any identifiable structural abnormalities. Stress and anxiety can exacerbate IBS symptoms, and since you mentioned feeling worried about the possibility of colon cancer, this anxiety could be contributing to your symptoms.

However, your concern about colon cancer is understandable, especially with the symptom of persistent abdominal pain and changes in stool consistency. While colon cancer can present with abdominal pain, it typically also includes other symptoms such as significant changes in bowel habits, blood in the stool, unexplained weight loss, or severe fatigue. If you are not experiencing these additional symptoms, the likelihood of colon cancer may be lower, but it is essential to address your concerns with your healthcare provider.

Considering your ongoing symptoms and the fact that you have not yet undergone a colonoscopy, it may be prudent to discuss this option with your doctor. A colonoscopy can help visualize the colon and rectum, allowing for the detection of any abnormalities, including polyps or tumors. It is a standard procedure for individuals experiencing unexplained gastrointestinal symptoms, especially if there is a family history of colorectal cancer or if you are over the age of 45.

In addition to a colonoscopy, it may be beneficial to explore other potential causes of your left upper abdominal pain. Conditions such as gastritis, pancreatitis, or even splenic issues could be contributing to your discomfort. A thorough evaluation by a gastroenterologist, including imaging studies like an abdominal ultrasound or CT scan, may provide further insights.

Lastly, managing anxiety and stress is crucial, as these factors can significantly impact gastrointestinal health. Techniques such as cognitive-behavioral therapy, mindfulness, and relaxation exercises can be beneficial in alleviating anxiety and may help improve your symptoms.

In summary, while your symptoms warrant further investigation, particularly with a colonoscopy, it is also essential to consider functional gastrointestinal disorders and the impact of stress on your health. Open communication with your healthcare provider about your concerns and symptoms will be key in finding an appropriate diagnosis and treatment plan.
