Seeking Guidance on Managing Diarrhea Following Contaminated Swimming Exposure

8/2/2025, 4:10:25 PMMale25-34

Background: I'm an 18-year-old female with a prior diagnosis of irritable bowel syndrome (IBS), but I'm not currently taking any medications for gastrointestinal issues. Additionally, I've been diagnosed with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), meaning any physical effort significantly drains my energy, especially since I’m already feeling fatigued and sleep deprived after a rough night. My medication regimen includes a low dose of naltrexone (4.5 mg) and propranolol (40 mg). Some medical professionals consider my immune system to be compromised due to these conditions, although that remains uncertain. Situation: Recently, I swam in water that was later confirmed to be contaminated with feces. Three days post-exposure, I began to experience severe diarrhea, with over ten episodes occurring last night, accompanied by intense abdominal cramps. I resorted to taking Imodium in the morning as the discomfort became unbearable. Currently, visiting a doctor is not feasible for me; my only alternative would be to go to the emergency room, which I would find challenging. However, since the Imodium seems to be alleviating my symptoms, I suspect they might dismiss me at the ER due to improved conditions, so I am opting for self-monitoring at this point. Inquiry: I'm finding it difficult to locate reliable information regarding this situation online. I would appreciate guidance on what actions I should take or avoid, as well as any critical symptoms I should be on the lookout for. I have taken three Imodium tablets this morning but plan not to take any more today to allow any possible toxins to clear from my system. I’m struggling with both food and liquid intake, although I do have some appetite, thus I’ll continue to make an effort. At what stage should I begin to worry? Any advice would be greatly appreciated! :)

It's understandable that you're feeling anxious about your situation, especially considering your existing conditions and recent exposure to contaminated water. Let’s break down your concerns regarding diarrhea, potential next steps, and critical symptoms to watch for.

Main Points:

  • You are likely experiencing diarrhea due to recent exposure to contaminated water.
  • Imodium can help with symptom relief, but you should monitor your symptoms carefully.
  • There are specific warning signs that would indicate it's time to seek medical help.

Explanation:

After exposure to contaminated water, gastrointestinal symptoms like diarrhea can arise as the body attempts to eliminate harmful substances. Imodium (loperamide) can provide temporary relief by slowing down bowel movements, which could be helpful if you're feeling a need for symptom control.

However, since you have a history of IBS, it's crucial to be cautious, especially as you might already be at increased risk for gastrointestinal issues. The fact that you're feeling fatigued and have existing health conditions adds a layer of complexity, making self-care during this episode particularly important.

Specific Next Steps:

  1. Hydration:

    • Prioritize fluid intake to prevent dehydration, which can happen quickly with diarrhea. Aim for clear fluids like water, broth, or electrolyte solutions (like Pedialyte).
    • Sip small amounts frequently rather than drinking large quantities at once to make it easier on your stomach.
  2. Diet:

    • Stick to bland foods if you're feeling capable of eating (e.g., bananas, rice, applesauce, toast – often referred to as the BRAT diet).
    • Avoid dairy, caffeine, fatty foods, and spicy items until your symptoms stabilize.
  3. Monitor Symptoms:

    • Keep a close eye on your symptoms over the next 24-48 hours. Document any changes, including the frequency of diarrhea, intensity of abdominal cramps, and any new symptoms.
    • Perform regular checks for warning signs that necessitate emergency care:
      • Severe dehydration: signs include dry mouth, extreme thirst, little or no urination, dizziness, or confusion.
      • Blood in stool: any traces of blood or dark, tarry stools.
      • Prolonged symptoms: If diarrhea continues for more than 48-72 hours without improvement, or if symptoms worsen.
  4. Consider Rest:

    • Given your ME/CFS, it’s crucial to manage your energy levels. Rest as much as possible to aid recovery and minimize fatigue.
  5. Evaluate Imodium Use:

    • Since you’ve taken Imodium, consider your body’s need to expel toxins. If symptoms worsen or if you haven't improved by tomorrow, it might be wise to reconsider seeking medical advice, even if it’s challenging.

Your health and comfort are paramount. If you experience any of the above warning signs, please reach out for medical help, even if it feels daunting. Remember to take care of yourself, and focus on hydration and rest as you navigate this. Let me know if you need further guidance or have more questions!

Unusual Hives and Digestive Issues

Over the last few days, I (19F) have started experiencing some unusual symptoms. I've dealt with gastrointestinal (GI) problems for about five years, yet I’ve never received a formal diagnosis, as my symptoms seemed relatively mild. I often find myself struggling with constipation, prompting me to use laxatives or drink prune juice occasionally. Bloating follows nearly every meal, particularly when I indulge in carbohydrates. Recently, however, I’ve encountered some strange occurrences. Just yesterday, my stomach felt extremely gassy and bloated, causing considerable discomfort. To my surprise, every attempt to have a bowel movement resulted only in foam. Furthermore, I noticed peculiar single hives appearing on my arm and thigh, but not elsewhere on my body. These hives are red, itchy, and slightly elevated. I’m unclear whether they’re connected to my digestive troubles, but I thought it was worth mentioning. Does anyone have insights on what might be happening? Any suggestions would be appreciated!

Could My Digestive Issues Be Related to Anxiety or Is There Something More?

At 15 years old, I’m a girl who has experienced digestive challenges throughout my life, which have left me underweight and unable to eat as much as I should. I've undergone numerous medical tests for conditions like celiac disease and various allergies, but all results came back clear. My physicians attributed my difficulties to the need for better dietary choices and my anxiety. However, over the past year, the severity of my stomach problems has escalated, significantly impacting my daily routine, especially in school, and increasing my anxiety levels beyond where they were before. I regularly deal with nausea before and after meals, a sensation of fullness that comes after just one bite, and discomfort that often arises upon waking or during the night. The most distressing symptom is probably the acid reflux; it manifests as intense pain in the mornings, making me feel ravenous, even after forcing myself to eat a substantial dinner the previous night. I’ve sought information on this, discovering it could indeed be linked to acid reflux. Despite trying Tums for relief, I haven’t found any improvement. This pain often arises as I lie down in bed at night to sleep. Given these escalating issues, should I consider revisiting a healthcare professional for further evaluation, or is it better to simply try to disregard the symptoms? Might they genuinely just be tied to anxiety?

Seeking Help for Persistent Digestive Issues

At 26 years old, I find myself grappling with ongoing gastrointestinal problems that have persisted for the past year. After meals, I often have the unsettling sensation that my stomach is empty again very quickly. I sometimes experience sudden bouts of weakness, fatigue, and even headaches, which affect my concentration. Additionally, I have loose stools two to three times a day, and I frequently deal with gas and the uneasy feeling of incomplete digestion. I’ve noticed that consuming fermented products or sugary beverages like tea and coffee exacerbates my symptoms, leading me to suspect that I might not be absorbing the nutrients from my food effectively. I've sought the expertise of several healthcare professionals and was prescribed Rifaximin at a dosage of 550 mg, which provided only temporary relief. Unfortunately, my symptoms resurfaced after the course of the medication ended. I am now looking for further insights regarding potential diagnoses and sustainable treatment options. Any recommendations or next steps would be greatly appreciated.

Advice Wanted on Iron Deficiency Concerns

At 19 years old, I'm currently not on any medications, apart from a herbal syrup intended to assist with regulating my menstrual cycle. Even though it may not be directly related, I should mention that I have polycystic ovary syndrome (PCOS), likely of the adrenal variety, and I’ve been dealing with gastrointestinal issues for several years. I underwent a blood test recently, and the results indicated that my serum iron and transferrin saturation are below normal, while my UIBC is elevated and TIBC is within a normal range. I’m uncertain about how to make sense of these results, but I have been experiencing symptoms indicative of iron deficiency for quite a long time, which prompted me to seek a professional opinion. These symptoms include: - Persistent fatigue - Frequent bruising - Pale complexion and lips - A generally unhealthy appearance - Poor blood circulation - Occasional dizziness and visual disturbances whenever I stand up after sitting or lying down. Additionally, my vitamin D levels are quite low at 17 ng/mL, which may be exacerbating some of these symptoms. In response, I have begun taking 6000 IU of vitamin D in syrup, once weekly, under guidance for a duration of 3 to 4 months. Regarding iron intake, several family members have suffered from iron deficiency as well and have successfully managed it with supplements. However, due to my digestive issues, I’ve been advised against taking iron tablets, as they could aggravate my stomach problems. My diet is fairly nutritious, as I consume a variety of fibrous foods and focus on a vegetarian menu, preparing meals at home almost exclusively. Occasionally, I include beetroots, pomegranates, and other iron-rich foods. Nevertheless, I am unsure of further steps to enhance my iron levels. The ongoing symptoms are quite bothersome and negatively affect my daily life, so any suggestions would be greatly appreciated.

Facing Diarrhea on the Eve of a Long Journey

Hello everyone, I’m in quite a predicament, and I’ll do my best to keep this discussion appropriate while still addressing the issue at hand. My current health situation is less than ideal. To provide some background, I’m a 21-year-old woman weighing 160 pounds, and I’m 5’5" tall. I live with POTS syndrome and PCOS, and I’m currently on birth control as well as naproxen. I have a prescription for zofran but do not smoke. Earlier today, I was running errands with my sister after work. I have a job located about an hour from my home, and my sister resides in the same town where I work. Around 6:30 PM, I started experiencing stomach cramps, which became increasingly painful over time. By 7:30 PM, while we were shopping in Old Navy, the discomfort intensified. To provide some context, I’d also gotten up to use the restroom six times within just four hours, which might or might not be relevant but seemed worth noting. While standing in the checkout line, the cramps became unbearable, forcing me to excuse myself to find a bathroom. It was a rather alarming sensation, combining the urgency to relieve myself with a nauseating feeling. The nature of the cramping was different from menstrual cramps, as the pain was higher in my abdomen. Interestingly, just last weekend, I battled the stomach flu and had sought treatment at urgent care; however, I felt fine by Monday and had no symptoms this week until now. For breakfast today, I consumed a strawberry smoothie and a chicken Caesar salad for lunch. To clarify, this definitely is not appendicitis since I underwent surgery to remove my appendix last October. While in the bathroom at Old Navy, my stool was quite loose, though not fully at the diarrhea stage at that moment. After finishing my business, I still felt considerable cramping. I dropped my sister off at her home and then endured the long drive back. During the ride, although I still felt unwell, thankfully, there was no urgent need to use the restroom again. Upon arriving home, I didn’t have the energy to prepare a meal and lacked an appetite, so I settled for a few saltine crackers. However, after eating just five, I was suddenly overwhelmed by a dire need to rush to the bathroom again. This time, what followed was truly the most severe diarrhea I’ve ever experienced, resembling straight liquid. Now, I’m left with a painful stomach and deeply concerned about the prospect of experiencing this again. I have an eight-hour road trip planned for tomorrow, and I’m uncertain how I’m going to manage under these conditions. I plan to adhere to the bland diet suggested for stomach issues, consisting of bananas, rice, and toast, yet I urgently need to devise a plan to halt this situation immediately. The thought of being on a long drive and repeatedly needing to request stops is mortifying. Any advice or guidance you could share would be greatly appreciated!
