Symptoms: Colon Cancer or Irritable Bowel Syndrome?

Colorectal cancer or irritable bowel syndrome?

Recently, I've been experiencing some bloating in my lower abdomen, accompanied by mild pain, and I've been having some difficulty with bowel movements, which seems like constipation.
However, there is no blood in my stool! The color is normal, and the consistency is neither very hard nor very soft.
I've also lost about four kilograms, possibly due to the cold weather and not eating much, as well as walking home from school.
I've heard that metabolism speeds up in cold weather, and I've been doing housework too.
I looked up colon cancer online, and I'm really scared of that disease.
I don't have any symptoms of anemia or anything like that.
If it is irritable bowel syndrome and I don't see a doctor, what could happen?

Hello, Miss.
It seems you are experiencing constipation (one of the symptoms of irritable bowel syndrome, not colon cancer, just poor motility).
Please increase your intake of fruits and vegetables.
If necessary, you can visit a gastroenterologist to check for occult blood in your stool.
Changhua Hospital cares about your health.

More Info

When it comes to gastrointestinal symptoms such as alternating diarrhea and constipation, abdominal pain, and changes in bowel habits, it's understandable to be concerned about the possibility of serious conditions like colon cancer. However, it's important to differentiate between symptoms that may indicate colon cancer and those that are more consistent with conditions like Irritable Bowel Syndrome (IBS).

Colon cancer can present with a variety of symptoms, but it is often characterized by more persistent changes in bowel habits, such as a significant change in the frequency or consistency of stools, the presence of blood in the stool, unexplained weight loss, and persistent abdominal discomfort. In your case, while you mentioned experiencing abdominal bloating and some difficulty with bowel movements, you also noted that your stool color is normal and that there is no blood present. These are positive signs, as the absence of blood and the presence of normal stool color can often indicate that more serious conditions may be less likely.

Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder that can cause symptoms similar to what you are experiencing, including abdominal pain, bloating, and changes in bowel habits (such as alternating between diarrhea and constipation). IBS is often triggered by factors such as stress, diet, and lifestyle changes. Given that you mentioned a recent decrease in food intake due to cold weather and possibly increased physical activity, these factors could also contribute to your symptoms.

In terms of weight loss, a four-kilogram decrease can be concerning, but it is essential to consider the context. If this weight loss is due to reduced caloric intake and increased activity, it may not be alarming. However, if you are experiencing unintentional weight loss without a clear reason, it is advisable to consult a healthcare professional.

Regarding your concerns about IBS and whether it requires medical attention, it is generally a manageable condition. Many people with IBS find relief through dietary changes, stress management, and sometimes medication. However, if your symptoms persist, worsen, or if you develop new symptoms such as significant weight loss, blood in the stool, or severe abdominal pain, it would be prudent to seek medical evaluation.

In summary, while your symptoms could be indicative of IBS, they do not strongly suggest colon cancer, especially given the absence of blood in the stool and significant weight loss. It is always best to consult with a healthcare provider for a thorough evaluation, especially if you have a family history of colon cancer or if your symptoms change. Regular screenings, such as colonoscopies, are recommended for individuals with a family history of colon cancer or those over the age of 45, as early detection is key in managing any potential issues effectively.
