Understanding blood in stool can be a concerning issue, especially for young adults. The presence of blood, whether bright red or darker, can indicate various underlying conditions, and it’s essential to approach this symptom with caution. Given your description of experiencing abdominal pain, diarrhea, and the subsequent finding of blood on toilet paper and in mucus, it’s understandable that you are worried about serious conditions such as colorectal cancer.

Firstly, let's address the potential causes of blood in the stool. In young adults, the most common causes include:
1. Hemorrhoids: Swollen blood vessels in the rectum or anus can cause bright red blood during bowel movements. They are often associated with straining, constipation, or prolonged sitting.

2. Anal fissures: Small tears in the lining of the anus can occur due to passing hard stools, leading to pain and bleeding.

3. Gastrointestinal infections: Bacterial or viral infections can cause inflammation in the intestines, leading to diarrhea and blood in the stool.

4. Inflammatory bowel disease (IBD): Conditions like Crohn's disease or ulcerative colitis can cause inflammation in the digestive tract, resulting in symptoms such as abdominal pain, diarrhea, and blood in the stool.

5. Diverticular disease: Diverticulosis can lead to diverticulitis, which may cause bleeding.

6. Polyps or colorectal cancer: While less common in younger individuals, polyps can develop in the colon and may bleed. Colorectal cancer is typically more prevalent in older adults, but it can occur in younger individuals, especially if there is a family history or genetic predisposition.

Given that you have undergone a rectal examination and were told there was inflammation, it’s crucial to follow up on this. The sensation of persistent urgency and the feeling of an "object" in the rectum can be related to several factors, including anxiety about the symptoms, ongoing inflammation, or even muscle spasms in the anal region.

Here are some recommendations for your situation:
1. Follow-Up Care: Since you have already seen two doctors, consider seeking a gastroenterologist for a more specialized evaluation. They may recommend further diagnostic tests, such as a colonoscopy, to visualize the colon and rectum directly.

2. Dietary Adjustments: Ensure you are consuming a balanced diet rich in fiber to help prevent constipation, which can exacerbate hemorrhoids and fissures. Staying hydrated is also crucial, especially if you have experienced diarrhea.

3. Monitor Symptoms: Keep track of any changes in your bowel habits, the frequency and nature of the blood, and any accompanying symptoms such as weight loss, fever, or significant changes in appetite.

4. Stress Management: If anxiety is contributing to your symptoms, consider stress-reduction techniques such as mindfulness, yoga, or talking to a mental health professional.

5. Avoid Straining: When using the bathroom, try to avoid straining, as this can worsen hemorrhoids and fissures. If you experience constipation, consider using stool softeners or laxatives as recommended by a healthcare provider.

In summary, while the presence of blood in the stool can be alarming, many causes are treatable and not necessarily indicative of cancer. However, given your age and the symptoms you describe, it is essential to pursue further evaluation to rule out any serious conditions. Always prioritize open communication with your healthcare providers and advocate for your health until you receive satisfactory answers.
