ถ่ายเป็นเลือด...ไม่ดี อาการแบบนี้น่าเป็นห่วง

Every morning, after waking up, it&#8217;s normal to head to the bathroom for personal business. However, if one day you notice blood in your stool, it can be quite alarming. Many people might panic and fear they have a serious condition, such as colon cancer. 
 
But before jumping to conclusions, don&#8217;t be alarmed. Associate Professor Dr. Thanyadej Nimmannwuthipong, who is the specialist at the Advanced Technology Surgery Center (ASIT) at Phayathai 3 Hospital, is here to answer all your questions about experiencing blood in your stool.
&nbsp;
<h2>Understanding the Severity of Blood in Stool</h2>
Blood in the stool can be alarming and may manifest in different ways. Sometimes, you might notice drops of blood after a bowel movement, or you may see blood mixed with your stool, changing its usual color. The way blood appears can help diagnose various conditions, and it&#8217;s important not to assume it&#8217;s just due to hemorrhoids. If you experience this symptom, it’s crucial to consult a doctor promptly for accurate information, leading to proper diagnosis and treatment.
<h2> 
Blood in Stool: A Sign of Potential Illness</h2>
Dr. Thanyadej explains how the severity of the underlying condition can be assessed based on the amount of blood and the frequency of the bleeding. Patients with significant bleeding are at a higher risk of serious conditions. For instance, if you notice blood dripping after a bowel movement, it could indicate an issue with the blood vessels near the anus. On the other hand, if the stool is mixed with blood or consists of blood alone, it suggests there may be a significant problem within the large intestine.
<h2> 
Common Conditions Associated with Blood in Stool</h2>
Hemorrhoids 
Blood in the stool is a primary symptom of hemorrhoids, which can occur due to straining during bowel movements caused by constipation or diarrhea. This straining leads to swollen blood vessels around the anal area, forming hemorrhoids. In severe cases, inflamed hemorrhoids may protrude, causing significant pain when walking or sitting. As a result, blood may appear during bowel movements, either as drops after passing stool or staining toilet paper. The stool itself usually remains normal in color. Some individuals may experience intermittent symptoms without pain, while others may suffer from discomfort in the anal area, itching, and difficulty in bowel movements.
<h2> 
Abnormal Blood Vessel Conditions in the Colon</h2>
Abnormal conditions of small blood vessels in the colon can lead to bleeding during bowel movements, resulting in fresh blood in the stool, either in clots or as watery blood. This is more commonly observed in individuals over 70 years old, and typically occurs without abdominal pain. While some may experience spontaneous cessation of bleeding, it is advisable to seek medical attention to rule out other potential issues.
&nbsp;
<h2>Colorectal Polyps</h2>
Colorectal polyps are growths resulting from genetic abnormalities, predominantly found in males over 50 years old. These polyps can develop anywhere in the colon and may increase the risk of colorectal cancer. Although patients often show no symptoms, some may notice blood in their stool, which can appear as a thin coating of blood. It is recommended that individuals over 50 undergo regular screenings to detect any potential polyps.
<h2> 
Colorectal Cancer</h2>
Colorectal cancer is one of the most common cancers in Thailand and worldwide, primarily affecting individuals over 60 years old. Patients may experience abnormal bowel habits, such as constipation or diarrhea, along with blood in their stools. In some cases, severe blood loss can lead to anemia. Colorectal cancer often presents in the abdominal section of the colon rather than the rectum and is associated with a diet high in fats and genetic factors. Unfortunately, colorectal cancer is generally not curable, requiring endoscopy or other methods for diagnosis and removal of malignant tissue to prevent further progression.
<h2> 
Inflammatory Bowel Disease (IBD)</h2>
Inflammatory bowel disease can arise from certain infections, such as dysentery, and is characterized by symptoms including watery diarrhea, frequent bowel movements, fever, loss of appetite, and abdominal pain. Patients may notice mucus or blood in their stool, necessitating further treatment.
<h2> 
Preventing Blood in Stool: A Key to Colorectal Cancer Prevention</h2>
Dr. Thanyadej offers essential self-care tips to help prevent colorectal cancer, which is among the most commonly diagnosed cancers, alongside breast and cervical cancers. 
 
1. Eat Fiber-Rich Foods 
Incorporate plenty of fiber into your diet by consuming fruits and vegetables, such as bananas and papayas. A fiber-rich diet helps prevent constipation, which can lead to complications. 
 
2. Avoid High-Fat and Spicy Foods 
Steer clear of foods high in fat and those that are overly spicy, as they can irritate the digestive system and contribute to gastrointestinal issues. 
 
3. Stay Hydrated 
Drink at least eight glasses of water a day. If possible, limit or avoid alcoholic beverages, as they can dehydrate you. 
 
4. Respond to Nature’s Call Promptly 
When you feel the urge to have a bowel movement, don’t hold it in. Delaying bowel movements can lead the large intestine to absorb too much water, causing the stool to become hard and difficult to pass. Establish a routine, such as going to the bathroom after waking up. 
 
5. Practice Proper Bowel Habits 
Avoid straining while trying to pass stool, as this can cause blood to pool in the rectal area, leading to swelling and potential tears. If you enjoy reading while in the bathroom, try to limit your time and complete your business promptly. 
 
6. Exercise Regularly 
Incorporate regular physical activity into your routine, and try not to sit or stand for extended periods. Increased pressure in the veins around the rectum can elevate the risk of hemorrhoids. A strong body and well-conditioned muscles can also help prevent constipation. 
 
7. Wash After Bowel Movements 
After using the bathroom, rinse with water instead of relying solely on toilet paper. Rough toilet paper can irritate the sensitive tissues around the anus, leading to abrasions. These abrasions can create entry points for bacteria found in stool, potentially causing infections.
