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:
- Shiga Toxin E. coli (STEC) can cause long-lasting symptoms but is usually not a chronic infection.
- Given your immunocompromised status, monitoring and managing symptoms is essential.
- 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:
-
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.
-
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).
-
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.
-
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.
-
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.
-
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.

Understanding Tuberculosis Exposure Risk
A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.
24M | Unexplained Fainting Incident
**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
Healing Progress Post-GBS: Toe Concerns
I am a 28-year-old male, measuring 5 feet 10 inches and weighing 131 pounds. My current medications include Fomadatine and Zyrtec, prescribed due to my ongoing battle with Chronic Gastritis and SIBO. I maintain a healthy lifestyle, abstaining from both smoking and alcohol. My health concern revolves around the toe adjacent to my pinky toe on my left foot, as well as my pinky toe on the right foot. Since August of last year, I have been on the mend from Guillain Barre Syndrome. Recently, I've noticed that at night, the skin on my feet tends to turn a reddish pink, although this usually improves after I walk around. However, two of my toes have remained red, with one appearing slightly swollen. Generally, my pinky toes are quite thick, but the condition of my left foot's toe is worrisome for me. It seems that I'm unable to upload an image to illustrate my issue.
Challenges with Appetite and Discomfort While Eating — Difficulty in Gaining Weight
As an 18-year-old male, I find that I become satisfied after consuming rather minimal amounts of food. This situation presents a considerable challenge, particularly since I only need to have a standard breakfast, lunch, or dinner to feel completely satiated for the remainder of the day. My goal of increasing my weight has made this issue even more complicated. When I limit myself to one meal per day, I often face weight loss or an uncomfortable sensation of fullness that leaves me feeling sluggish. Opting for two meals makes me feel excessively bloated, distracting me from my daily responsibilities. Moreover, I suffer from an unusual issue with my throat, where almost any food I consume causes discomfort, as detailed in the list below. I have contemplated focusing on having just lunch while continuing my weightlifting regimen to maintain my current weight and gradually build muscle. What advice could you offer? Could there be an underlying cause for these symptoms? Lastly, would it be wise for me to consult a healthcare professional? Foods That Cause Discomfort: Bread, flour, pizza, fruits, sugary or starchy items, seed oils, chips, and essentially everything else. Foods That Are Tolerable: Rice, salads, chicken, fish, and vegetables. Overall Symptoms Include: * Quick satiety after normal meals * Challenges in gaining weight * Bloated and lethargic sensations when consuming more than one meal * Persistent throat sensitivity to a wide variety of foods
Seeking Insights: My Journey with Undiagnosed Neurological Symptoms
Hello everyone, I'm a 34-year-old female grappling with neurological symptoms that first appeared in October, and I’m eager to hear from anyone who might have faced similar challenges. My journey began with unexpected migraines, blurred vision, and an ongoing sensation of being off-balance or intoxicated. Gradually, I began experiencing mainly sensory-related symptoms, such as tingling and burning sensations, feelings of extreme heat and cold, sharp pains radiating in my arms and back, as well as discomfort in my hands and toes, alongside intermittent numbness. I also endure varying degrees of weakness and heaviness in my right side, specifically my arm and leg, although I haven’t suffered complete functional loss. The nature of my symptoms is erratic; they fluctuate rather than consistently deteriorate. An MRI revealed mild, scattered lesions in the white matter, which were deemed nonspecific. Further tests from a lumbar puncture returned normal results, showing no markers of inflammation, and the oligoclonal bands were not present. A thorough range of lab tests yielded no significant findings. After evaluating my case, the neurology team suggested a possible diagnosis of MS and administered a three-day course of intravenous steroids. While I noticed a slight improvement in some sensory pain, my symptoms persist and continue to vary day by day. I still experience headaches and pressure in my head along with episodes of blurred vision, but there have been no new deficits since treatment. I am reaching out to connect with others who have had similar experiences. I would like to learn about the insights or diagnoses you encountered and what treatments proved beneficial (such as those related to migraine disorders, dysautonomia, or sensory neuropathy, for example). If you have navigated a similar path, I would greatly appreciate your sharing your story. Thank you!
