Mucus in Stool: Causes and When to Seek Medical Help

Mucus in stool

Hello Doctor: This past week, I've been experiencing some constipation (only small pellets) and sometimes feel the urge to use the restroom but end up sitting for a long time without being able to go.
I've also noticed yellow-green mucus leaking from my anus (for about a week now), and there is a slight pain at the anal opening.
My stool has also been mixed with white and yellow-green mucus.
I went to Taoyuan Min* Hospital to see a gastroenterologist, and the doctor examined me and said there were no specific wounds and did not see any pus-like fluid, only a small external hemorrhoid (possibly because I cleaned myself before the examination out of fear of the doctor checking my anus).
The doctor prescribed anti-inflammatory medication, but after returning home, the yellow-green mucus is still leaking.
Is there something wrong with my body? Do I need to get an X-ray to check my gastrointestinal tract, or should I consider going to another hospital for further examination?

Hello! The presence of mucus in the stool, along with constipation, painful bowel movements, yellow-green discharge, and external hemorrhoids, can be concerning.
It is normal for stool to contain some mucus; however, if there is an excessive amount with a foul odor, it may indicate inflammation.
A stool test can be conducted to check for any infections.
If there is no improvement and the mucus persists, it is advisable to follow up with a colorectal specialist to investigate for potential anal fissures, inflammation, or abscesses.
Wishing you health and safety! Sincerely, Dr.
Lin Ming-Hui, Attending Physician, Internal Medicine, Taoyuan Hospital, Ministry of Health and Welfare.

More Info

Understanding mucus in stool can be a complex issue, as it can arise from various underlying causes. Mucus is a normal component of the gastrointestinal tract, produced by the intestines to lubricate the lining and facilitate the passage of stool. However, when there is an increase in mucus production, especially if accompanied by other symptoms, it may indicate an underlying health issue that requires attention.

In your case, the presence of yellow-green mucus, along with symptoms of constipation and slight pain around the anal area, could suggest several possibilities. One common cause of mucus in the stool is irritation or inflammation of the intestinal lining, which can occur due to conditions such as irritable bowel syndrome (IBS), infections, or inflammatory bowel diseases (IBD) like Crohn's disease or ulcerative colitis. The fact that you are experiencing constipation and difficulty passing stool could also indicate a functional issue with your bowel, which may be exacerbated by dietary factors, dehydration, or stress.

The yellow-green color of the mucus may suggest that there is some form of infection or inflammation present. Infections can lead to increased mucus production as the body attempts to flush out pathogens. Additionally, the presence of a small external hemorrhoid, as noted by your doctor, could also contribute to discomfort and changes in bowel habits, although it is less likely to be the primary cause of the mucus.

Given that your symptoms have persisted for about a week and you are experiencing ongoing mucus discharge, it is advisable to seek further medical evaluation. While your initial visit to the gastroenterology department provided some insights, if the symptoms do not improve or worsen, it may be beneficial to pursue additional diagnostic tests. These could include imaging studies such as an abdominal ultrasound or CT scan, which can help visualize any structural abnormalities in the gastrointestinal tract. A stool test may also be warranted to check for infections or other abnormalities.

In terms of dietary adjustments, consider increasing your fiber intake gradually, staying well-hydrated, and avoiding foods that may irritate your digestive system, such as spicy foods, caffeine, and alcohol. Over-the-counter medications may help alleviate constipation, but it is essential to consult with your healthcare provider before starting any new treatment.

In summary, while mucus in stool can be a benign finding, the combination of your symptoms warrants further investigation. If your current healthcare provider is unable to provide satisfactory answers or if your symptoms persist, seeking a second opinion from another gastroenterologist may be a prudent course of action. Early diagnosis and management are crucial in addressing any potential underlying conditions effectively.
