Foul Odors: What Your Stool Says About Your Gut Health

What about the smell of feces?

I previously asked a question about gastroesophageal reflux, which has been ongoing for about three weeks (the doctor noted some bleeding from the photos).
I am currently on medication.
Since I live outside and the restroom provided is enclosed, with air conditioning only when the light is on, it is for personal use.
Today, when I opened the door, I smelled a sour odor and noticed that the trash can was not properly covered.
I suspect that it might be due to used toilet paper.
I would like to ask if used toilet paper that has been in the trash for about a week, particularly from wiping after a bowel movement, would emit a sour smell due to the oxidation of the feces?
Additionally, I have been experiencing diarrhea frequently over the past two to three months and have had gastroenteritis.
I have also been considered to possibly have irritable bowel syndrome.
Would this affect my colon? I had a colonoscopy last year, which showed no issues.

Hello, basically besides gastroesophageal reflux, the digestive function of the gastrointestinal tract is also poor.
It is recommended to adjust your diet by reducing oil, dairy, irritating foods, and meat, which should help improve the symptoms.
Wishing you good health.

Understanding foul odors in stool and their implications for gut health can provide valuable insights into your digestive system's condition. The odor of stool is primarily influenced by the types of bacteria present in the gut, the foods consumed, and the overall health of the gastrointestinal tract.
When it comes to the specific question about the smell of used toilet paper that has been in a closed trash can for about a week, it is indeed possible for it to emit an acidic or sour odor. This is due to the decomposition of organic matter, including fecal matter, which can produce various gases and compounds as it breaks down. Bacteria that thrive in moist environments can also contribute to the foul smell. If the toilet paper has been in contact with stool, it can certainly develop a strong odor, especially if it has been left to sit for an extended period. The combination of moisture, warmth, and organic material creates an ideal environment for bacteria to flourish, leading to the production of volatile organic compounds that can smell sour or acidic.

Regarding your gastrointestinal health, experiencing diarrhea frequently, especially after having had gastroenteritis, can indicate an underlying issue. Conditions like irritable bowel syndrome (IBS) can indeed affect the colon, leading to symptoms such as abdominal pain, bloating, and changes in bowel habits. While a colonoscopy last year showed no issues, it's essential to consider that gastrointestinal conditions can develop or change over time. The presence of IBS or other functional gastrointestinal disorders can lead to increased sensitivity in the gut, affecting how it reacts to certain foods, stress, and other environmental factors.

It's also worth noting that stress can significantly impact gut health. Stress can alter gut motility, increase gut permeability, and change the composition of gut microbiota, all of which can contribute to symptoms like diarrhea and discomfort. If you are experiencing ongoing gastrointestinal symptoms, it may be beneficial to keep a food diary to identify any potential triggers and discuss these findings with your healthcare provider.

In summary, the foul odor from used toilet paper can indeed be attributed to the decomposition of organic matter, including fecal material. Frequent diarrhea and a history of gastrointestinal issues warrant further investigation, especially if symptoms persist. It's crucial to maintain open communication with your healthcare provider to monitor your symptoms and adjust your treatment plan as necessary. Additionally, consider lifestyle modifications, such as stress management techniques and dietary adjustments, to support your gut health.
