Blood in Stool: Causes and When to Seek Help - Gastroenterology and Hepatology

Blood in stool can be a concerning symptom, and understanding its potential causes is crucial for determining when to seek medical help. In your case, the presence of red liquid accompanying your stool, especially if it is mixed with brown stool, could indicate a few different things.

Firstly, the deep brown and light brown colors of your stool suggest that you are likely experiencing normal variations in stool color, which can be influenced by your diet. Foods like dragon fruit (火龍果) can sometimes lead to changes in stool color due to their pigments. However, the presence of red liquid is more concerning and should not be overlooked.

Here are some potential causes for blood in the stool:
1. Hemorrhoids: These are swollen veins in the lower rectum or anus that can cause bright red blood in the stool. If you have been experiencing straining during bowel movements or discomfort in the anal area, this could be a likely cause.

2. Anal fissures: Small tears in the lining of the anus can occur, especially if you are experiencing hard stools. This can lead to bleeding during bowel movements.

3. Gastrointestinal bleeding: This can occur from various sources, including ulcers, diverticulosis, or more serious conditions like inflammatory bowel disease (IBD) or colorectal cancer. The color of the blood can help indicate the source; bright red blood typically suggests bleeding from the lower gastrointestinal tract, while darker blood may indicate bleeding from higher up in the digestive system.

4. Dietary factors: Certain foods can cause changes in stool color. For example, beets can cause reddish stools, and foods high in fiber can lead to softer stools. However, if the red liquid is distinctly separate from the stool, it may not be related to dietary changes.

Given your symptoms, it is important to monitor your condition closely. If the red liquid persists, if you experience pain, or if you notice any other symptoms such as changes in bowel habits, weight loss, or fatigue, you should seek medical attention promptly. A healthcare provider can perform a thorough evaluation, which may include a physical examination, a review of your medical history, and possibly diagnostic tests such as blood tests or imaging studies.

In summary, while some variations in stool color can be normal, the presence of red liquid is a sign that warrants further investigation. It is always better to err on the side of caution when it comes to health concerns, especially those involving potential bleeding. If you have any doubts or if your symptoms worsen, do not hesitate to consult a healthcare professional for advice and appropriate care.
