Understanding Green Stool: Dietary Causes or Potential Illness?
A heads-up that the following involves some frank discussion about bodily functions! My partner (24M) and I (23F) have both noticed that our stools have turned a light green over the past several days. This change has been accompanied by some digestive disturbances, including noisy stomachs, significant fatigue, and mild feelings of nausea. Thankfully, there hasn’t been any diarrhea or vomiting, but my stool has felt softer than usual and seems to pass with urgency. A few days back, my boyfriend mentioned spotting a small amount of blood once, though it was minor and hasn’t recurred since. Initially, I thought the green color might be linked to a recent health-focused phase where we added spinach to nearly every meal. However, I'm now starting to worry that it might indicate a possible infection. I'm curious if anyone has insights into what might be happening here. We have enjoyed swimming at Lake Murray and recently spent some time floating down the river, but none of our friends who joined us have reported experiencing similar symptoms. Just to clarify for context—I’m not currently taking any medication. I did just finish a course of antibiotics which wouldn’t account for us both experiencing the same symptoms. For reference, I weigh about 190 lbs and stand 6 feet tall, while my boyfriend is around 120 lbs and 5'7.

The change in stool color to light green, along with digestive disturbances and fatigue, can often be related to dietary factors, but it’s important to consider other possible causes as well. Given your recent increase in spinach consumption and the mild digestive symptoms you both are experiencing, it seems likely that your diet is a significant contributor. However, the presence of soft stool, urgency, and the isolated instance of blood are reasons to be vigilant.
Explanation:
- Dietary Factors: Spinach, along with other green leafy vegetables, can cause stools to become green due to their high chlorophyll content. Additionally, if you’ve recently increased your fiber intake suddenly, it can lead to digestive disturbances including softer stools and gas.
- Possible Infections or Illness: While the symptoms you listed could be related to diet, gastrointestinal infections (viral or bacterial) can also lead to changes in stool color and texture. The minor spotting of blood could signal irritation, particularly in the digestive tract, but it’s good that it hasn't recurred.
Next Steps:
- Hydration: Ensure both you and your partner are drinking plenty of fluids to stay hydrated, especially if you’re having any mild digestive issues.
- Monitor Symptoms: Keep a close watch on your symptoms. If the green stool persists beyond a few days, or if you notice increased frequency, severity, or recurrence of blood in the stool, it’s essential to seek further evaluation.
- Dietary Adjustments: Consider reducing your intake of high-fiber foods like spinach for a bit to see if the symptoms improve. Gradually reintroducing them can help you assess if they are the cause.
- Consider a Food Diary: Track what you eat and how it correlates with your digestive symptoms, which can help identify triggers.
- Consult a Healthcare Professional: If symptoms worsen or new symptoms arise (like persistent nausea, severe abdominal pain, or significant fatigue), it would be wise to reach out for medical advice.
It's understandable to be concerned, especially with changes in bodily functions. Monitor how you both feel, and take care of each other during this time.

Seeking Advice for Gastritis Management and Weight Concerns
I am a 26-year-old man who has been battling gastritis for approximately a year and a half. Although I haven't been on a consistent medication regimen, I've taken various treatments intermittently. I live a lifestyle that excludes smoking and drinking, and I eliminated soft drinks from my diet about six to seven months ago. Despite this, I haven’t adhered to a strict dietary plan, treating myself occasionally to fried foods, burgers, gluten, and spicy dishes, both when I’m on medication and when I’m not. Recently, I’ve experienced an unintended weight loss of nearly 5 kg over the past two months, which has caused me considerable concern. I’m afraid this could escalate into more severe issues, potentially ulcers or even cancer, given the worst-case scenario. I recently underwent an endoscopy, the results of which I have documented separately, and I received a prescription for the following medications to be taken over the next two weeks: - Levofloxacin 500 mg tablets - Amox CTL 500 mg - Dexlansoprazole 60 mg delayed-release capsules - Itopride Hydrochloride 50 mg - Multivitamin + Antioxidant tablets I’m reaching out to seek your guidance on how to better manage my health going forward. The findings from my endoscopy indicate chronic gastro duodenitis with erosions, and I am eager to find ways to improve my well-being.
Insights Needed on GLP-1 Medications like Ozempic
Hello everyone! I have a somewhat spontaneous request. I am currently collaborating on a research initiative with Dr. Odette Norton and Dr. Angela Hinz, and we would greatly appreciate your insights regarding GLP-1 receptor agonists and their role in weight management. Despite their growing popularity, there is surprisingly little information available on the opinions of healthcare professionals and the hurdles they may encounter when prescribing these medications. We invite you to participate in our study conducted by the UniSC School of Health and Behavioural Sciences. We are particularly looking for professionals from the medical and psychological fields who work with clients experiencing weight issues. Our goal is to gather expert feedback on the advantages of these medications, along with the potential challenges they may pose, such as patients' expectations, prescribing pressures, issues related to weight bias, body image, and disordered eating. We are seeking the contributions of general practitioners and specialized medical professionals (such as bariatricians and gastroenterologists), as well as psychologists who currently or have previously assisted patients dealing with weight-related concerns. Participation entails filling out an anonymous online survey, which should take around 20 minutes of your time. Your valuable perspectives will enhance our understanding of healthcare providers’ views on weight loss medications and help in crafting resources aimed at assisting those supporting patients using GLP-1 treatments for weight reduction. By clicking the link, participants can directly access the study. Please don’t hesitate to share this link with any other health professionals who qualify and may be interested in contributing.

Sudden Health Woes: Seeking Insights
I should start by mentioning that I'm not very familiar with Reddit—this was posted on r/medical previously, but I didn’t receive the engagement I was hoping for. I’m sharing this out of desperation since my online research hasn’t led to any useful information, and I can’t afford a visit to the doctor unless absolutely necessary. To give some background, I’m quite petite, standing at 5'3" and typically weighing under 100 lbs at 18 years old. My highest weight has been around 107 lbs, but that was years ago. I’ve struggled to gain weight despite trying, and just to clarify, I am definitely not pregnant and there’s no chance of that happening. Throughout my life, I've encountered a myriad of health issues. I’ve had instances of fainting (often linked to heat or skipping meals, though I’ve improved at managing these), high anxiety levels, and a wonky digestive system that rarely functions normally for more than three days at a stretch. From around 14 to 16 years old, particularly in my freshman year (2020), I started experiencing uncontrollable shivering and mild nausea upon waking. It would take about half an hour for the shaking to subside, regardless of whether I got up or moved around, and I would feel fine for the rest of the day. Initially, I attributed these episodes to stress from schooling or unrest at home, although they have continued sporadically, often correlating with my gut health issues. Now to the present situation—over the past three days, my digestive health has sharply declined. I’ve been getting up exceptionally early and battling nausea to the point of almost vomiting; it has progressively worsened each day. I’ve been through enough discomfort in the past, but this particular episode has raised my concern. I can’t pinpoint anything specific I’ve consumed that could have caused this, and no one else in my household is experiencing similar symptoms. Last night, I attempted to fall asleep hoping the uneasy feeling in my stomach would subside, but I woke abruptly around 6 am (normally, I wake around 7 or 8) and had to keep a bucket nearby due to persistent nausea that was neither escalating to vomiting nor diminishing. I found myself spending a significant part of the morning in the bathroom until the discomfort finally eased. I felt drained afterward but still managed to eat something. During dinner, I noticed I became full exceptionally quickly. I prepared a small portion but barely managed to eat half. Once again, I sought sleep in hopes of alleviating my discomfort. However, less than forty minutes later, I jolted awake in a panic, as my body seemed to be on autopilot. I was intensely nauseous, fearful that any movement might trigger vomiting, and I battled dizziness that felt peculiar—almost as if my brain was out of sync. It was intense yet lasted less than a minute, although it felt much longer at the time. Checking my phone, I discerned that I had only been asleep for about an hour, which is unusual for me; I’m accustomed to waking up a bit early in the mornings, not shortly after dozing off. I retrieved my bucket, visited the restroom (my urine was normal, indicating I’m likely not dehydrated), and managed to lie back down. Soon after, I began trembling again and felt the need for constant yawning. My body is warm, though I’m unsure if I have a fever since I feel quite alert. As of now, I’m feeling more stable. Online resources typically suggest checking for issues like blood pressure, dehydration, or ear infections. I suspect it could be connected to blood pressure, especially since we have suspected diabetes within my family. I did get blood work done a few weeks ago and await the results. (I’m also considering the possibility of IBS-D.) Often, I come across advice to modify one’s diet or limit caffeine intake, but this is difficult for me financially. I have reduced my caffeine consumption and have done without my usual coffee for several days to see if it makes a difference, but the situation seems to be worsening rather than improving. Does anyone have insights or suggestions on what might be going on? (Updates will come in the following days if my condition changes or if I find myself feeling better about what might turn out to be a minor issue.) **Edit #1**: I managed to fall back asleep and woke up at five again, trembling uncontrollably with slight nausea. My neck felt unusually warm, but everything else seemed okay. **Edit #2**: I've noticed that larger meals tend to provoke nausea too; I'm now eating smaller portions more frequently. **Edit #3**: It's been about a day since the last update, and I’m still unable to eat full meals. I’ve been keeping hydrated since we spent the day outdoors in the sun. After returning home, I managed to eat a few fries and a chicken tender before experiencing gut pain again. My body cleared itself out over the course of about forty minutes. (Note: Although this post is presently written, the events described occurred three or four days ago. I haven’t experienced severe nausea since, but am still contending with digestive issues and eating difficulties.)
26-Year-Old Female with Weight Loss and GI Symptoms: Is it SMAS?
Hello everyone, I am a 26-year-old woman (assigned female at birth, standing 5'9" and weighing 138 pounds, a steady decrease over 6 months), and I have been grappling with a range of gastrointestinal issues that have become quite distressing. While I understand that Superior Mesenteric Artery Syndrome (SMAS) is uncommon, the reality is that I am losing weight, feeling unwell, and I’m desperately seeking answers that might explain my situation. **Symptoms I’ve Been Experiencing:** - Unplanned weight reduction that began after a period of significant weight gain, rapidly transforming into quick weight loss that has slowed but persists. - Oily stools. - A varying gastrointestinal pattern: experiencing constipation for 2-3 days followed by 1-2 days of urgent, oily diarrhea. - Nausea that typically appears mid-morning (definitely not pregnant). - A sense of fatigue post-meals; large portions make me feel quite ill for hours thereafter. - Positional sensitivity: sometimes, I notice a slight improvement when lying on my left side or stomach, although I have only recently started to pay attention to this. **Diagnoses I Currently Have:** - Diagnosed with Postural Orthostatic Tachycardia Syndrome (POTS). - Suspected hypermobile Ehlers-Danlos Syndrome (hEDS) — while not officially diagnosed, I demonstrate hypermobility, bruise easily, and exhibit symptoms suggesting connective tissue issues. Genetic testing has ruled out classic EDS. **Tests Conducted:** - Upper and lower gastrointestinal endoscopy – results were normal. - MRCP – showed no significant findings. - Chest CT – clear, no abnormalities detected. - Abdominal X-ray – indicated constipation and stool burden. - Laboratory tests – all within normal ranges. - Fecal elastase – measuring 89 (below 40 was concerning), but the pancreatic specialist dismissed the possibility of Exocrine Pancreatic Insufficiency (EPI) due to no pancreatic damage, nor was there evidence of pancreatitis, Cystic Fibrosis, Celiac Disease, Ulcerative Colitis, Crohn’s, or IBS/IBD. They suggested I stop enzyme therapy. I was advised to return if symptoms persist, potentially considering testing for Small Intestinal Bacterial Overgrowth (SIBO) at that point. **Current Medications Include:** - Zoloft 100 mg (gradually decreasing). - Effexor 75 mg (gradually increasing). - Adderall XR and IR (20 mg and 5 mg, respectively). - Trazodone (as needed for sleep, 50 mg). - Xyzal 5 mg. - Fiber supplements (husk). - Kyleena IUD. **Reasons for Considering SMAS:** - The combination of alternating constipation, steatorrhea, weight loss, and nausea could indicate partial obstruction of the duodenum. - SMAS tends to occur more frequently in slender females or those who have undergone fast weight loss. - Although I haven’t undergone a CT or MR angiogram to evaluate the angle of my superior mesenteric artery or aortomesenteric distance, I am contemplating whether to request these scans. **My Main Inquiry:** Could my symptoms indicate SMAS or perhaps another condition like Median Arcuate ligament syndrome (MALS)? I am cautious about self-diagnosing or pursuing rare conditions. However, when faced with persistent symptoms that don’t point to any other diagnosis, I believe it is important to explore all possibilities. Thank you for taking the time to read my lengthy post. I am earnestly seeking answers, as I believe each health challenge has a root cause, and I am determined to uncover it.
