Abdominal concerns?

There is noticeable swelling in the abdomen to the right of the navel, more pronounced than on the left side.
At night, when lying down, bowel sounds are particularly loud, to the point that people nearby can hear them, and this is not just a brief occurrence but continues persistently.
Initially, there was stomach pain, and I consulted a doctor four times, who diagnosed it as gastroenteritis.
I originally had diarrhea, but after taking medication, the diarrhea stopped, and I switched to constipation, alternating between diarrhea and constipation.
With the Lunar New Year approaching, I am unsure what to do.
The right abdomen is clearly swollen, but it doesn't hurt much, and there is no sensation of blood in the stool.
Pressing on it does not cause pain, and I have been eating less than before but still feel full.
There is no loss of appetite or other symptoms, but because only the right abdomen is persistently swollen while the left is not, could this be colon cancer?

If you are experiencing gastrointestinal discomfort, you can start by eating smaller, more frequent meals and try to avoid irritating foods, particularly those that are high in fat, high in protein, and spicy or heavily flavored.

More Info

When it comes to abdominal swelling, particularly on the right side, there are several potential causes, and while colorectal cancer is one of them, it is essential to consider a broader range of possibilities. Your symptoms, including significant swelling, changes in bowel habits (alternating between diarrhea and constipation), and notable bowel sounds, warrant a thorough evaluation.

Firstly, the right side of the abdomen houses several important organs, including the appendix, cecum, and parts of the small intestine. Swelling in this area can be attributed to various conditions, such as appendicitis, inflammatory bowel disease (IBD), infections, or even benign conditions like cysts or tumors. Colorectal cancer typically presents with additional symptoms, such as blood in the stool, significant weight loss, or changes in appetite, which you have not reported. However, it is important to note that some individuals may experience colorectal cancer without these classic symptoms, especially in the early stages.

The fact that your abdominal swelling is more pronounced on the right side and that you have experienced alternating diarrhea and constipation could suggest a functional gastrointestinal disorder, such as irritable bowel syndrome (IBS). IBS can cause significant abdominal discomfort, bloating, and changes in bowel habits, but it is not associated with cancer. However, the presence of persistent symptoms should not be ignored.

Your previous diagnosis of gastroenteritis indicates that there may have been an infection or inflammation in your gastrointestinal tract. While gastroenteritis can lead to temporary changes in bowel habits, if symptoms persist or worsen, further investigation is warranted. It is also worth noting that the absence of pain upon palpation and the lack of blood in your stool are somewhat reassuring signs, but they do not completely rule out serious conditions.

Given your ongoing symptoms, it is crucial to follow up with your healthcare provider. They may recommend imaging studies, such as an abdominal ultrasound or CT scan, to assess for any structural abnormalities, masses, or signs of inflammation. Additionally, a colonoscopy may be indicated to visualize the colon directly and obtain biopsies if necessary.

In terms of your concerns about colorectal cancer, it is essential to consider risk factors such as age, family history, and personal medical history. If you have a family history of colorectal cancer or other gastrointestinal cancers, this may increase your risk and warrant more proactive screening.

In summary, while your symptoms could potentially be related to colorectal cancer, they are more likely indicative of a functional gastrointestinal disorder or residual effects from a previous infection. It is essential to continue working with your healthcare provider to monitor your symptoms and pursue appropriate diagnostic testing. Early detection and intervention are key to managing any potential health issues effectively. If you experience any new or worsening symptoms, such as significant pain, fever, or changes in bowel habits, seek medical attention promptly.
