Frequent Foul Gas and Blood in Stool: Gastrointestinal Issues - Gastroenterology and Hepatology

Chronic foul-smelling flatulence with bloody diarrhea?


Hello doctor, I have been experiencing frequent and foul-smelling flatulence along with bloating for quite some time.
About three months ago, I suspected there was blood in my stool and underwent a fecal occult blood test, which came back normal.
The doctor mentioned that I was too anxious.
Recently, I have been having acute diarrhea often, accompanied by mucus and blood.
When I consulted a doctor, they only diagnosed it as intestinal inflammation and prescribed medication, but it has been over ten days and there has been no improvement.
Just now, after eating hot pot, I immediately had diarrhea with noticeable mucus and blood streaks.
This also happened the last time I ate.
I am unsure what to do now; the doctor seems unconcerned, but I did not see any blood in my stool when it came out.
Could you please advise me on this situation?

It sounds like you are experiencing a complex set of gastrointestinal symptoms that are understandably concerning. Frequent foul gas, abdominal bloating, and the presence of blood or mucus in your stool can be indicative of several underlying issues, and it’s important to approach this situation with careful consideration.

Firstly, the presence of blood in your stool, even if it is not consistently visible, should never be taken lightly. Blood can appear in various forms, such as bright red, which often indicates bleeding from the lower gastrointestinal tract (like hemorrhoids or anal fissures), or darker, tarry stools, which suggest bleeding from higher up in the digestive system (like the stomach or small intestine). The fact that you have also noted mucus in your stool could suggest inflammation in the intestines, which is often seen in conditions like irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) such as ulcerative colitis or Crohn's disease, or infections.

Given that you have already undergone stool tests and seen a doctor who diagnosed you with intestinal inflammation, it is crucial to follow up on this diagnosis. If your symptoms have not improved with the prescribed medications, it may be time to seek a second opinion or request further testing. This could include a colonoscopy, which allows for direct visualization of the colon and can help identify any lesions, inflammation, or other abnormalities. Additionally, tests for infections, food intolerances, or allergies might be warranted, especially if your symptoms seem to correlate with specific foods, such as the hot pot you mentioned.

The foul-smelling gas and bloating you are experiencing could be related to several factors, including dietary choices, gut microbiota imbalances, or malabsorption issues. Foods that are high in sulfur, such as certain meats and cruciferous vegetables, can lead to particularly foul-smelling gas. If you have recently changed your diet or are consuming foods that are difficult for your body to digest, this could contribute to your symptoms.

Moreover, stress and anxiety can exacerbate gastrointestinal symptoms. If you have been feeling anxious about your health, this could potentially worsen your gut issues. It is important to address both the physical and psychological aspects of your health. Consider discussing your anxiety with a healthcare provider, as they may recommend counseling or stress management techniques that could help alleviate some of your gastrointestinal symptoms.

In summary, your symptoms warrant further investigation. It is essential to communicate openly with your healthcare provider about the persistence of your symptoms and your concerns. If necessary, advocate for additional testing or a referral to a gastroenterologist who specializes in digestive disorders. Keeping a detailed diary of your symptoms, dietary intake, and any other relevant factors can also be beneficial in identifying triggers and guiding your healthcare provider in making a more accurate diagnosis.

Lastly, while it is understandable to feel anxious given your symptoms, try to focus on the steps you can take to seek appropriate care and support. Your health is important, and addressing these issues proactively will help you find relief and improve your quality of life.
