Unusual Bowel Odor: Causes and Solutions

The odor of feces continues?

Hello, Dr.
Lin: I have been experiencing this for a week now, and it never happened before.
I haven't been passing gas, yet my body still has a fecal odor that seems to be getting worse each day.
Even when I don't want to have a bowel movement, there is still a smell.
Additionally, I feel a constant twitching or gas-like sensation around my anus that I can't control.
I wonder if it's because I wash my bottom every day.
I'm concerned that if this continues, I might break down.
My colleagues act like nothing is wrong, but I know there is an odor coming from me, and it's quite strong.
They have even commented about me passing gas, but I haven't.
Why is there still a smell if I'm not passing gas? Doctor, what should I do? I'm feeling very lost.

Hello Mr.
Wu,
Regarding your questions, this is the first time I have encountered such issues, but we can discuss them in several parts:
1.
Concerning whether there is a problem with the colon, you can schedule an examination at an outpatient clinic.
If there are no anatomical issues, you may also visit a medical center to check for any dysfunction of the anal sphincter.
2.
Regarding the unusual odor you mentioned, I would recommend seeing an otolaryngologist to check for any nasal conditions or olfactory issues.
3.
Are there other conditions that could cause body odor? Yes, for example, axillary osmidrosis (commonly known as body odor).
Here is some information for your reference:
The strong odor from the armpits is due to a higher number of apocrine glands (also known as sweat glands) compared to the average person.
The secretions contain fatty acids, which are oily and viscous, and they rise from the hair follicle to the skin surface.
Bacteria in the armpit break down these secretions, producing an ammonia-like body odor.
Apocrine glands are located in areas such as the nipples, armpits, genital region, and external ear canal.
After puberty, these glands are stimulated by hormones and begin to secrete.
By the age of fifty or sixty, the glands gradually atrophy, and the odor diminishes.
Statistics show that up to 60% of Westerners have a strong body odor, while only about 10% of Easterners do.
Dr.
Chen Hsi-Ken, a plastic surgeon at Tri-Service General Hospital, analyzed two factors that influence the development of apocrine glands:
1.
Individuals with denser hair tend to have more active sweat glands.
2.
Genetics: If one parent has axillary osmidrosis, the child has a 50% chance of having it; if both parents have it, the likelihood increases to 80-90%.
What can be done?
1.
Maintain good hygiene in the armpits.
After heavy sweating, it is best to take a shower and change into clean clothes.
In summer, shaving armpit hair can reduce bacterial growth and lower body odor.
2.
Surgical treatment to eliminate axillary osmidrosis involves removing the apocrine glands, which can completely resolve the issue.
Note that after surgery, you should not raise your arms for three days, as the armpits need to be wrapped in gauze to apply pressure for hemostasis and reduce the risk of hematoma and infection.
Additionally, traditional Chinese medicine may have other diagnostic insights, which you could explore with a TCM practitioner.
I apologize for not being able to provide a definitive answer to your questions.
Wishing you good health.
Best regards,
Lin Hong-Mao

More Info

Understanding unusual bowel odor can be quite distressing, especially when it is accompanied by other symptoms such as abdominal discomfort or changes in bowel habits. Based on your description, it seems you are experiencing a combination of unusual bowel odor, a sensation of involuntary muscle contractions around the anal area, and a feeling of discomfort that is affecting your daily life and interactions with others.

First, let's address the potential causes of the unusual odor. Bowel odor can be influenced by several factors, including diet, gastrointestinal health, and the presence of any underlying conditions. Foods that are high in sulfur, such as garlic, onions, and cruciferous vegetables (like broccoli and cabbage), can lead to stronger odors. Additionally, if you have recently changed your diet or are consuming more processed foods, this could also contribute to changes in odor.

Another important factor to consider is the state of your gut microbiome. An imbalance in gut bacteria can lead to digestive issues, including changes in bowel odor. Conditions such as irritable bowel syndrome (IBS), infections, or malabsorption syndromes can also alter the smell of your stool and the odor emanating from your body. If your body is not effectively breaking down food, it can lead to the production of foul-smelling gases, which might explain why you feel a sense of odor without actually passing gas.

The sensation of involuntary contractions or spasms around the anal area could be related to several factors, including anxiety, stress, or even a condition known as pelvic floor dysfunction. This can lead to a feeling of urgency or discomfort, which may exacerbate your concerns about odor. Stress and anxiety can also impact your digestive system, leading to symptoms such as bloating, changes in bowel habits, and increased sensitivity to bodily sensations.

Given that you have been experiencing these symptoms for a week and they are causing you significant distress, it is crucial to seek medical advice. A healthcare professional can perform a thorough evaluation, including a physical examination and possibly laboratory tests, to rule out any underlying conditions. They may also inquire about your diet, lifestyle, and any recent changes that could be contributing to your symptoms.

In the meantime, here are some strategies that may help alleviate your symptoms:
1. Dietary Adjustments: Consider keeping a food diary to track what you eat and how it correlates with your symptoms. Reducing intake of foods known to cause gas or odor may be beneficial. Focus on a balanced diet rich in fruits, vegetables, whole grains, and lean proteins.

2. Hydration: Ensure you are drinking enough water throughout the day, as proper hydration can aid digestion and help maintain regular bowel movements.

3. Probiotics: Incorporating probiotics into your diet, either through supplements or fermented foods like yogurt, kefir, or sauerkraut, may help restore balance to your gut microbiome.

4. Stress Management: Engage in relaxation techniques such as deep breathing, meditation, or yoga to help manage stress, which can have a positive impact on your digestive health.

5. Hygiene Practices: Continue to maintain good hygiene, as this can help minimize any odor. Regular washing and using gentle, unscented products can be beneficial.

6. Consult a Specialist: If symptoms persist, consider consulting a gastroenterologist or a healthcare provider specializing in digestive health. They can provide targeted treatment options based on your specific condition.

In conclusion, while unusual bowel odor can be a source of embarrassment and concern, it is essential to approach the situation with a focus on understanding the underlying causes and seeking appropriate medical advice. By addressing your symptoms holistically and with professional guidance, you can work towards finding relief and improving your overall digestive health.
