Frequent flatulence and bleeding?


Hello doctor, two weeks ago I went to Chang Gung Memorial Hospital's colorectal surgery department for an examination due to hemorrhoids.
The doctor only prescribed oral medication and ointment, but two weeks have passed and I haven't improved.
Since last Friday, I've been experiencing constant flatulence and bleeding, and the gas has an unusual odor.
Which department should I visit and what tests should I undergo?

If you are experiencing persistent gas and bleeding after a recent visit to the colorectal department for hemorrhoids, it is essential to take these symptoms seriously. The presence of unusual gas and rectal bleeding can indicate various gastrointestinal issues that may require further evaluation.

First and foremost, you should schedule an appointment with a gastroenterologist. This specialist focuses on diagnosing and treating disorders of the gastrointestinal tract, which includes the esophagus, stomach, intestines, and rectum. Given your recent symptoms, a gastroenterologist will be well-equipped to assess your condition and recommend appropriate tests.

During your visit, the doctor will likely conduct a thorough medical history and physical examination. They may ask about the nature of your bleeding (e.g., how much blood, color, and consistency), the characteristics of your gas (e.g., frequency, odor), any associated symptoms (such as abdominal pain, changes in bowel habits, or weight loss), and your dietary habits. This information is crucial for determining the underlying cause of your symptoms.

Based on your initial assessment, the gastroenterologist may recommend several diagnostic tests, including:
1. Colonoscopy: This is a procedure that allows the doctor to examine the inner lining of your colon and rectum using a flexible tube with a camera. It can help identify issues such as polyps, inflammation, or other abnormalities that may be causing your symptoms.

2. Upper Endoscopy: If there are concerns about upper gastrointestinal bleeding or issues related to the stomach or esophagus, an upper endoscopy may be performed.

3. Stool Tests: These tests can help detect the presence of blood in the stool, infections, or other gastrointestinal conditions.

4. Imaging Studies: Depending on your symptoms, the doctor may recommend imaging studies such as an abdominal ultrasound or CT scan to visualize the organs and structures in your abdomen.

5. Dietary Assessment: Since you mentioned changes in gas and bowel habits, the doctor may also discuss your diet and recommend keeping a food diary to identify any potential triggers.

It is important to note that persistent gas and rectal bleeding can be caused by various conditions, including hemorrhoids, anal fissures, diverticulitis, inflammatory bowel disease (IBD), or even colorectal cancer. Therefore, timely evaluation and diagnosis are crucial.

In the meantime, here are some self-care tips that may help alleviate your symptoms:
- Dietary Adjustments: Avoid foods that are known to cause gas, such as beans, lentils, carbonated drinks, and certain vegetables (like broccoli and cabbage). Instead, focus on a balanced diet rich in fiber, which can help regulate bowel movements.

- Hydration: Ensure you are drinking plenty of water to help soften stool and prevent constipation, which can exacerbate hemorrhoid symptoms.

- Over-the-Counter Medications: If you are experiencing discomfort, over-the-counter medications such as simethicone can help reduce gas. However, consult your doctor before taking any new medications.

- Avoid Straining: When using the bathroom, try to avoid straining, as this can worsen hemorrhoids and lead to further bleeding.

If your symptoms worsen or you experience severe abdominal pain, significant changes in bowel habits, or any other alarming symptoms, seek immediate medical attention. Remember, early intervention can lead to better outcomes and prevent potential complications.
