When it comes to gastrointestinal health, understanding the signs and symptoms can be crucial for early detection and treatment of potential issues. Let's address your questions one by one.

1. Can you see hidden blood in stool?
Hidden blood, or occult blood, is not visible to the naked eye. It requires specific tests, such as a fecal occult blood test (FOBT), to detect. This type of blood can be a sign of various gastrointestinal issues, including polyps, ulcers, or cancers. If you suspect hidden blood, it is important to consult a healthcare provider for appropriate testing.

2. If I see red in my stool but no blood on toilet paper, could it be hidden blood?
If you notice a reddish hue in your stool but do not see any blood on the toilet paper or in the toilet water, it is less likely to be occult blood. However, it could indicate the presence of certain foods (like beets) or other non-blood-related issues. If you are concerned, it is advisable to undergo a stool test to rule out any underlying conditions.

3. Could mucus in stool without blood indicate colon cancer?
Mucus in the stool can be a normal occurrence, especially if you are experiencing changes in your diet or bowel habits. However, if it is persistent or accompanied by other symptoms such as weight loss, changes in bowel habits, or abdominal pain, it could warrant further investigation. While mucus alone is not a definitive sign of colon cancer, it can be associated with conditions like inflammatory bowel disease (IBD) or colorectal cancer. A consultation with a healthcare provider is recommended for a thorough evaluation.

4. Is the area of left upper abdominal pain related to the left colon?
The left upper abdomen primarily houses the stomach, spleen, and parts of the pancreas and left kidney. The left colon, or descending colon, is located lower in the abdomen. If you are experiencing pain in the left upper quadrant, it may not be directly related to the left colon but could be associated with the stomach or other nearby organs. Given your history of gastritis and esophagitis, it is possible that your symptoms are related to these conditions rather than the colon.

5. If there is a growth (cancer) in the left colon, would symptoms include hidden blood? What other symptoms might occur?
If there is a malignancy in the left colon, it can lead to various symptoms, including changes in bowel habits (diarrhea or constipation), abdominal pain, unexplained weight loss, and possibly blood in the stool. The blood may be visible or occult, depending on the location and size of the tumor. Other symptoms can include fatigue, anemia, and changes in appetite. If you have persistent symptoms or concerns, it is crucial to seek medical advice and possibly undergo a colonoscopy for direct visualization and biopsy if necessary.

In summary, while some gastrointestinal symptoms can be benign, others may indicate more serious conditions. It is essential to monitor your symptoms closely and consult with a healthcare provider for appropriate testing and diagnosis. Regular screenings, especially if you have a family history of gastrointestinal diseases or if you are experiencing concerning symptoms, can be vital for early detection and treatment.
