Chronic Diarrhea Unexplained for 12 Weeks
I am a 19-year-old female, standing at 5'8" and weighing 84 kg. Over the past three months, I have been experiencing chronic diarrhea that appeared suddenly. Throughout these 12 weeks, my stool has not reached a solid consistency; it's either very watery or extremely soft. The color usually ranges from orange to yellow, although I have also encountered very dark brown or near-black stools. Additionally, I experience abdominal pain that feels as though it is pressing against my spine, with minimal gas production. Sleep is elusive for me, and I often feel fatigued. Unfortunately, I have also had several incidents where I lost control and soiled myself. Certain foods do not seem to alleviate or exacerbate my condition; rather, it varies from day to day, swinging between extremely watery and somewhat manageable. My dietary habits have not been the best; I believe I might have Avoidant/Restrictive Food Intake Disorder (ARFID), as I have been following a one-meal-a-day (OMAD) pattern for nearly three years. My intake is severely limited, typically involving only five different foods in a month, with daily caloric intake usually below 1000 calories. Notably, there were no significant dietary changes coinciding with the onset of my diarrhea. Interestingly, prior to the development of my symptoms, I noticed a significant weight increase—a swing from 82 kg to 88 kg, fluctuating between 85 kg and back again. Once the diarrhea began, my weight fluctuations persisted but appeared less severe. However, just yesterday, the diarrhea worsened considerably, making it feel as if my body was on fire; this morning I weighed 85.4 kg, which has now dropped to 84.5 kg today, accompanied by heightened abdominal pain. I have also felt an unusual pulsing sensation in my abdomen today, which generally only happens after physical exertion. I’m seeking thoughts on what might be causing these issues and which specific tests I should request from my doctor. I have submitted a stool sample but have yet to have any blood tests done.

It sounds like you're experiencing quite a significant and uncomfortable situation with your chronic diarrhea and related symptoms. Given the duration of your symptoms and the impact they are having on your daily life, it's important to consider this carefully. Here’s a summary of key points related to your condition followed by some actionable steps.
Summary
You are dealing with chronic diarrhea lasting 12 weeks, abdominal pain, unusual stool colors, fatigue, and concerns about your weight and dietary habits. These symptoms, particularly the change in bowel consistency, can indicate various underlying health issues that may need to be explored further.
Explanation
Chronic diarrhea can arise from a range of causes, including infections (bacterial, viral, or parasitic), inflammatory bowel conditions (like Crohn's disease or ulcerative colitis), dietary intolerances or sensitivities (such as lactose intolerance or celiac disease), and even stress or psychological factors. The color and consistency of your stools, combined with your dietary restrictions and significant weight change, further complicate this picture.
Given that you have also noticed abdominal pain and other distressing symptoms, it’s critical to work towards obtaining a clearer diagnosis.
Next Steps
-
Follow Up on Medical Tests:
- Stool Analysis: Make sure to discuss the results of your stool sample with your healthcare provider to rule out infections or parasites.
- Blood Tests: Request a comprehensive blood panel, including tests for:
- Complete blood count (CBC) to check for signs of infection or anemia.
- Electrolytes to ensure you are not dehydrated.
- Liver and kidney function tests.
- Tests for conditions such as celiac disease (like tissue transglutaminase antibodies).
-
Documenting Symptoms:
- Keep a detailed symptom diary, noting the frequency, consistency, and color of your stools, along with associated symptoms like pain and fatigue. This can help your healthcare provider in the diagnostic process.
-
Dietary Review:
- While working with a healthcare professional, consider seeking guidance from a registered dietitian who specializes in gastrointestinal issues. They can help you diversify your diet safely and get adequate nutrition.
-
Hydration:
- Focus on staying well-hydrated to prevent dehydration, especially with frequent diarrhea. Oral rehydration solutions can help replenish lost fluids and electrolytes.
-
Monitor Weight:
- Keep track of any significant weight changes and report them to your doctor, as this can be critical for diagnosis and planning your treatment.
-
Seek Support:
- If you suspect ARFID or have concerns about your eating patterns, mental health support can be beneficial. Connecting with a mental health professional who understands dietary issues can provide additional strategies.
If symptoms worsen or you experience severe pain, fever, or weakness, seek immediate medical attention. Remember, you're not alone in this, and addressing these issues with healthcare professionals can lead to effective management and improvement in your quality of life.

Chronic Diarrhea for Three Weeks in a 54-Year-Old Male
I am a 54-year-old man who is generally in good health, standing at 5’10” and weighing 150 pounds. For the past three weeks, I have been experiencing diarrhea. It's not severe, but my bowel movements are consistently unformed. I’ve scheduled a visit with my doctor, who conducted a complete blood examination, including a CBC and additional tests, all of which returned normal results. Stool samples were also taken, and the culture indicated no significant growth. I'm still waiting for the results of the ova and parasite tests, which appear to be taking longer than expected. I understand the underlying concern here. Meanwhile, my doctor has prescribed antibiotics, advising me to begin taking them even before the stool test results are available. However, I am puzzled by this advice since the likelihood of a bacterial infection seems low. I have not yet commenced the antibiotics but have them on hand. In summary, should I hold off on taking the antibiotics until all stool analysis is concluded?
Health Concerns in a 21-Year-Old Male: Anxiety and Gastrointestinal Symptoms
At the age of 21, I find myself grappling with health anxieties. My medical history reveals a diagnosis of a mixed anxious-depressive disorder, with a notable tendency towards hypochondria. Recently, I underwent a blood test for the presence of blood in my stool which returned negative results about a month ago. Just a few weeks back, I also had my calprotectin levels measured alongside a complete hemogram, which showed elevated levels at 224. Occasionally, I experience mild discomfort in my lower left abdomen, particularly intensified after using the restroom. Additionally, the quality of my stool has become irregular; it floats and often contains mucus—sometimes in small amounts, at other times more conspicuously. After a period of weight loss, I recently gained a few kilos, which I irrationally attributed to potential cancer. My primary care physician has referred me to a gastroenterologist to further investigate my elevated calprotectin levels, reassuring me that it likely isn’t anything serious. Nevertheless, I cannot shake the fear that I may be harboring a tumor in my colon, leading to worst-case scenarios of late-stage cancer. These gastrointestinal symptoms have persisted for the last four years, and I worry that I may have overlooked them for far too long. In summary, my health has become a source of significant worry, compounded by my emotional state, and I fear the ramifications of these ongoing issues.
Concerns About Stomach Ulcers and Cancer Risk
Two weeks ago, I experienced a slight ache in my abdomen, and shortly after, I noticed blood in my stool. This discovery sent me into a panic as I feared it could be indicative of bowel cancer. However, after discussing my concerns with my parents, we concluded that it was likely just hemorrhoids. To be cautious, I decided to schedule an appointment with a physician. The day prior to my appointment, I had a heated argument with my dad, during which I began to experience significant pain in my upper abdomen. He provided support, and as the discomfort subsided a few minutes later, we both suspected that it might have stemmed from the stress caused by our argument. He mentioned that he experiences similar symptoms when under pressure. At my doctor's visit the next day, I explained my symptoms, including the blood and the pain following the fight with my dad. The doctor agreed with our earlier assessment, attributing the blood to hemorrhoids and the abdominal pain to stress. However, later that day, when I tried to eat, the upper abdominal pain returned. While it wasn't as severe as it had been during the argument, it was still quite noticeable. Now, I've been researching my symptoms online, which has only heightened my anxiety regarding the possibility of having a stomach ulcer and the looming threat of stomach cancer, especially after discovering the poor survival rates associated with it. I also deal with an anxiety disorder, and this situation has intensified my worries. While there's no family history of stomach cancer, I've found out that certain viruses can trigger it irrespective of one’s genetic background. I am seeking advice on whether I should make another appointment with my doctor urgently or if I should consider visiting urgent care. If I experience any more abdominal pain, I will provide an update on my situation.
