When it comes to the presence of blood in the stool, it is essential to take this symptom seriously, as it can indicate various underlying conditions, some of which may require immediate medical attention. Given your description of having red spots in your stool and the presence of a red streak towards the end of your bowel movement, along with accompanying symptoms such as nausea and dizziness, it is advisable to consult a healthcare professional for further evaluation.

Blood in the stool can arise from several sources within the gastrointestinal tract. The most common causes include hemorrhoids, anal fissures, diverticular disease, and gastrointestinal bleeding from more serious conditions like colorectal cancer or inflammatory bowel diseases (IBD) such as Crohn's disease and ulcerative colitis. Since you mentioned that you previously had a negative fecal occult blood test, this may provide some reassurance, but it does not completely rule out the possibility of a significant issue, especially if new symptoms have developed.

The fact that you are experiencing nausea and dizziness could indicate that you may be losing blood, which can lead to anemia, especially if the bleeding is significant. Anemia can cause symptoms such as fatigue, weakness, and lightheadedness, which may explain your dizziness. Therefore, it is crucial to monitor your symptoms closely.

A colonoscopy is a diagnostic procedure that allows a physician to visualize the interior of the colon and rectum. It is often recommended when there are concerning symptoms such as blood in the stool, changes in bowel habits, or unexplained abdominal pain. Given your symptoms, a colonoscopy could be a valuable tool in determining the cause of the bleeding and any other potential issues within your gastrointestinal tract.

In addition to a colonoscopy, your healthcare provider may also consider other diagnostic tests, such as imaging studies or laboratory tests, to assess your overall health and identify any underlying conditions. It is important to communicate all your symptoms clearly to your doctor, including the duration and frequency of the blood in your stool, any changes in your bowel habits, and the presence of other symptoms like nausea and dizziness.

In summary, while the presence of blood in the stool can sometimes be attributed to benign causes such as hemorrhoids, it is essential to rule out more serious conditions. Given your symptoms and history, it would be prudent to seek medical advice and consider undergoing a colonoscopy for a thorough evaluation. Early detection and diagnosis are key to managing any potential gastrointestinal issues effectively. Always prioritize your health and do not hesitate to seek medical attention when you notice concerning symptoms.
