Alternating constipation and diarrhea?


Hello, about a month ago, I was having regular bowel movements, able to pass a large amount of stool within five minutes.
However, after my trip to Japan on June 30, I experienced mild diarrhea.
After taking loperamide, I ended up with constipation.
When I returned to my country on July 13, I had diarrhea again and took loperamide once more.
I thought this condition would improve after returning home (I experienced similar constipation after a trip to Japan last year, but returned to normal afterward).
However, after returning home and indulging in rich meals, I experienced constipation again, followed by another week of diarrhea, then constipation again.
Now, I am back to constipation, with an increased frequency of flatulence.
After eating, I feel a sense of urgency and heaviness, and I wake up in the morning feeling bloated.
The shape of my stool varies from thick to thin, but there is no blood in my stool.
My weight has actually increased rather than decreased, and I do not experience abdominal pain.
My grandmother has colon cancer, and I would like to know if my symptoms indicate a high chance of colon cancer.
Should I go to the hospital for an examination, or should I observe my symptoms at home for a while? How can you determine that my situation is less likely to be cancer? I have heard that alternating constipation and diarrhea can be a symptom of colon cancer, and I am really afraid of developing a serious chronic illness in my early twenties.
I am also hesitant to discuss this with my family.
If it is not cancer, will my condition improve on its own if I leave it untreated?

More Info


Understanding alternating constipation and diarrhea can be concerning, especially when there is a family history of colon cancer. However, it is essential to approach this situation with a clear understanding of the symptoms and their potential implications.

Firstly, alternating constipation and diarrhea is a symptom that can arise from various causes, not just colon cancer. Common reasons for these symptoms include dietary changes, stress, infections, irritable bowel syndrome (IBS), and other gastrointestinal disorders. In your case, the recent travel and dietary changes may have contributed to your symptoms. The consumption of rich foods, especially after a period of different eating habits, can lead to gastrointestinal disturbances.

The fact that you have experienced these symptoms intermittently, along with the absence of blood in your stool and significant weight loss, is a positive sign. Blood in the stool and unexplained weight loss are more concerning symptoms that warrant immediate medical evaluation. The presence of foul-smelling gas and changes in stool shape can be indicative of dietary issues or digestive problems rather than cancer.

While it is true that alternating bowel habits can be associated with colon cancer, especially in older adults or those with risk factors, your age and the nature of your symptoms suggest that it is less likely to be cancer at this stage. Colon cancer typically presents with more severe symptoms, including persistent changes in bowel habits, blood in the stool, abdominal pain, and weight loss. Given your age and the lack of alarming symptoms, the likelihood of colon cancer is relatively low.

However, it is crucial to listen to your body. If your symptoms persist or worsen, or if you develop new symptoms such as abdominal pain, changes in appetite, or any other concerning signs, it would be wise to seek medical attention. A healthcare provider can perform a thorough evaluation, which may include a physical examination, blood tests, and possibly imaging studies or a colonoscopy if deemed necessary.

In the meantime, consider keeping a food diary to track what you eat and how it affects your bowel habits. This can help identify any specific triggers related to your diet. Staying hydrated, maintaining a balanced diet rich in fiber, and managing stress can also help regulate your bowel movements.

In summary, while alternating constipation and diarrhea can be concerning, it is not definitive evidence of colon cancer, especially in your case. Monitoring your symptoms and seeking medical advice if they persist or worsen is the best course of action. Remember, early detection and intervention are key in managing any health issues, so do not hesitate to reach out to a healthcare professional if you have concerns.
