It sounds like you are experiencing a range of gastrointestinal symptoms that can be quite distressing. Based on your description, you have been dealing with alternating diarrhea and normal bowel movements, changes in stool shape, and noticeable bowel sounds. You also mentioned that you have been taking probiotics without seeing any improvement. Given your age and the nature of your symptoms, it is understandable to be concerned about conditions like irritable bowel syndrome (IBS) or even more serious issues such as colorectal cancer.

First, let's clarify what IBS is. IBS is a functional gastrointestinal disorder characterized by symptoms like abdominal pain, bloating, and changes in bowel habits, which can include diarrhea, constipation, or alternating between the two. It is important to note that IBS is diagnosed based on symptom patterns and the exclusion of other potential conditions. The fact that you are 20 years old and otherwise healthy makes it less likely that you would have colorectal cancer, as this condition is more common in older adults. However, it is essential to monitor your symptoms closely.

The symptoms you describe, such as the variability in your bowel habits and the presence of abdominal sounds, align with IBS. Stress, dietary choices, and lifestyle factors can all contribute to the exacerbation of IBS symptoms. Since you mentioned that your doctor suggested that your gastrointestinal system might be sensitive at your age, this aligns with the common understanding that younger individuals can experience functional gastrointestinal disorders more frequently.

Regarding your concerns about colorectal cancer, while it is a serious condition, the symptoms you describe do not typically present in a way that is characteristic of cancer, especially in someone your age. Colorectal cancer often presents with more severe symptoms, such as significant weight loss, persistent changes in bowel habits, blood in the stool, or severe abdominal pain. However, it is crucial to remain vigilant and consult with a healthcare professional if you notice any alarming changes, such as blood in your stool or persistent pain.

Since you have already consulted a doctor and were advised to observe your symptoms, it may be beneficial to keep a symptom diary. This diary can help track your bowel movements, any associated symptoms, dietary intake, and stress levels. This information can be valuable for your healthcare provider in determining the best course of action.
In terms of dietary management, consider keeping a food diary to identify any potential triggers. Common triggers for IBS can include dairy products, high-fat foods, caffeine, and certain types of carbohydrates known as FODMAPs. A low-FODMAP diet has been shown to help many individuals with IBS symptoms. Additionally, ensure you are staying hydrated and maintaining a balanced diet rich in fiber, which can help regulate bowel movements.

If your symptoms persist or worsen, it may be worthwhile to seek further evaluation from a gastroenterologist. They may recommend additional tests, such as a colonoscopy, to rule out any structural issues or other gastrointestinal disorders.
In summary, while your symptoms may suggest IBS, it is essential to continue monitoring your condition and consult with a healthcare professional if you have any concerns. Keeping a detailed record of your symptoms and dietary habits can provide valuable insights for your treatment plan. Remember, early intervention and lifestyle modifications can significantly improve your quality of life.
