Investigating Chronic Diarrhea and E. Coli: What Should I Know?

I am a 22-year-old female, standing at 5’2” and weighing 150 lbs, and I've been dealing with ongoing digestive problems for the last four years. Initially, I experienced periodic diarrhea and abdominal cramps, but over the past year, the situation has escalated to having diarrhea at least twice weekly, with particularly severe episodes occurring about once a month. These intense occurrences often lead me to cancel plans and miss work due to their debilitating nature. To find potential allergens in my diet, I've been carefully logging my food intake. Additionally, I underwent a series of laboratory tests to check for inflammation, Celiac disease, and lactose intolerance, all of which returned negative results. I have consulted a gastroenterologist and, together, we performed both a colonoscopy and an endoscopy. Contrary to what most people described as an extremely challenging preparation process, I found it significantly easier than managing my regular episodes. The results indicated slight gastritis but ruled out Crohn's disease and ulcerative colitis. Recently, I received results from my stool test, which confirmed a positive diagnosis for Shiga Toxin E. coli. This raises an important question: is this a new infection, or could I have been grappling with a long-standing infection that has caused my ongoing health issues? From my research, it seems that the majority of individuals typically recover from this infection relatively quickly; however, I am immunocompromised. For how long can this infection persist without treatment? To provide more background, I've been dealing with a thyroid condition that affects my immune system, and I am currently on Levothyroxine. This has resulted in frequent illnesses, often escalating to the point where I require antibiotics even for typical colds. My battle with mononucleosis began four years ago, during which I had two subsequent flare-ups within a two-year span. Medical professionals confirmed that I was inactive after each of these episodes, despite initial skepticism about such recoveries. Given my circumstances, I regularly undergo lab tests, typically monitoring my thyroid hormones (TSH, T3, T4), red and white blood cell counts, various immune-related markers, and occasionally liver and kidney panels. I maintain that if my E. coli infection had led to severe complications such as kidney problems, these would have been identified sooner. For further clarity, I spent over a year working as a zookeeper, in close proximity to exotic animals and their waste, which could be a potential source of E. coli infection. Since I departed from that job this past May, even if I contracted it there, it implies a minimum of four months of infection or potentially up to a year and a half. As I await a call from my doctor to discuss the findings, I find myself pondering the longevity of this E. coli infection. Is it truly feasible for someone to harbor E. coli for four months? Could it even extend for years? Am I about to present yet another medical mystery for doctors to unravel?

It sounds like you’re going through a really difficult time with your chronic digestive issues, especially with your recent diagnosis of Shiga Toxin E. coli. Let's break down what's happening and discuss your questions and next steps clearly.

Main Points:

1. Shiga Toxin E. coli (STEC) can cause long-lasting symptoms but is usually not a chronic infection.
2. Given your immunocompromised status, monitoring and managing symptoms is essential.
3. Immediate actions focus on hydration, dietary adjustments, and symptom management.

Explanation:

E. coli infections, particularly those caused by Shiga toxin-producing strains, are typically acute and last for a few days to a week in healthy individuals. However, because you are immunocompromised due to your thyroid condition and previous illnesses, your body may take longer to clear the infection.

Your concerns about harboring the infection for an extended time are valid. While it’s rare for someone to carry E. coli for months or years without treatment, there are cases where complications may lead to prolonged symptoms. Additionally, chronic gastrointestinal symptoms might arise from other underlying conditions or persistent irritation due to prior infections.

Next Steps:

1. Stay Hydrated: Ensure you are drinking plenty of fluids to stay hydrated, especially if you are experiencing diarrhea. Consider oral rehydration solutions to replenish electrolytes.

2. Diet Management: Since you have been logging your food intake, continue to avoid known triggers and focus on bland, easy-to-digest foods (like bananas, rice, applesauce, and toast).

3. Monitor Symptoms: Keep a detailed diary of your symptoms, noting any changes in frequency or intensity. This record will be helpful for your doctor in evaluating your condition more thoroughly.

4. Consult with Your Doctor: Once you receive a call, discuss the results of your stool test and your concerns about the duration of the infection and its potential implications. Ensure you express how the infection and your immunocompromised status could interact, and ask if further treatment (like antibiotics) might be necessary.

5. Stay Informed: Educate yourself about potential complications related to STEC, especially with your immune status. Possible complications, such as hemolytic uremic syndrome (HUS), can arise and should be monitored.

6. Follow Up on Health Habits: Consider revisiting your overall health management plan with your healthcare provider, addressing your thyroid condition and gastrointestinal issues collectively.

Your health journey sounds complex, and it’s understandable to feel uncertain. Stay connected with your healthcare team, and advocate for your concerns. Remember, you're not alone in this, and with appropriate monitoring and care, you can navigate these challenges effectively.
