Concerns Over Increased Bowel Movements Post-Meal in a 19-Year-Old Male
I am a male aged 19, generally healthy with no chronic illnesses. However, about a month ago, I experienced dehydration, and since the last three weeks, I have had an intense urge to have a bowel movement approximately 30 to 60 minutes after eating, sometimes up to six times in one day. Although my stools are firm, the frequency feels unusual for me. After consulting a doctor a week ago, I was informed that my previous dehydration might have affected my gut microbiome. The physician recommended a probiotic named *Sporlac* to aid in reestablishing a balance of beneficial gut bacteria. I initially followed the advice to take it twice daily for three days, but as there was no noticeable improvement, I escalated my intake to three times a day over the past four days. Additionally, I have been consuming between five to six liters of water each day and using oral rehydration salts as directed, yet my symptoms persist without any sign of relief. I am not currently taking any other medications, nor do I smoke, consume alcohol, or use recreational drugs. My eating habits remain unchanged. It has become quite uncomfortable for me to visit the restroom so frequently during college or with friends. I would appreciate any guidance on how to address this issue.

It's understandable to feel concerned about the increased frequency of your bowel movements post-meal, especially given its impact on your daily life. You are taking important steps to address this issue, but let’s explore some actionable advice that may help.
Main Points
- Increased bowel movements after eating can arise from various factors, including dietary changes, gut flora imbalances, and gastrointestinal sensitivity.
- Continuing your current regime of hydration and probiotics is good, but there might be other dietary or lifestyle adjustments that can further help.
- Keeping a symptom diary and monitoring specific food triggers could aid in pinpointing the cause.
Explanation
Typically, after eating, the gastrointestinal tract can stimulate peristalsis — the wave-like contractions that move food through your intestines. This effect can vary from person to person. While the doctor suggested that your previous dehydration might have influenced your gut bacteria, your sudden change in bowel habits may also relate to your diet or stress levels, especially as a college student.
Since your stools are firm, it seems unlikely that you are dealing with diarrhea, but rather an increased transit time through your digestive system. This could be related to an increased sensitivity to certain foods or simply your body readjusting post-dehydration.
Next Steps
-
Track Your Food and Symptoms: Keep a food diary for at least a week. Note what you eat and when you have bowel movements, including any symptoms like bloating or discomfort. Look for patterns — certain foods might trigger your increased urge.
-
Dietary Adjustments: Consider moderating the intake of foods that are known to stimulate bowel activity such as caffeine, spicy foods, dairy, and high-fiber items. Gradually reintroducing fiber can also help your gut adapt.
-
Timing of Probiotics: Since increasing the probiotics didn't yield expected results, try taking the probiotic with your meals as this can help with absorption. Stick to the recommended dosage rather than increasing it yourself without further guidance.
-
Hydration Balance: While staying hydrated is essential, drinking excessive amounts of water (like five to six liters) may cause your body to adjust in ways that you do not expect. Consider reducing water intake to a more typical range (about 2-3 liters a day) unless you feel increased thirst or there is a specific reason to hydrate more.
-
Mindfulness and Stress Management: Consider incorporating stress-relief techniques such as mindfulness, deep breathing, or physical activity as stress can impact gut motility.
If these measures do not help after a couple of weeks or if your symptoms worsen, it would be advisable to follow up with your healthcare provider again for further evaluation. They may suggest additional testing to rule out any underlying conditions, such as thyroid issues or gastrointestinal disorders.

Neck Discomfort Following a Cold
A 27-year-old female, weighing 120 pounds and measuring 5 feet 4 inches tall, reports no significant medical history or current medications. Recently, she embarked on a lengthy 10-hour flight, and shortly after, began to experience flu-like symptoms. The most prominent symptom was a sizable lump sensation in her throat while swallowing, accompanied by a persistent headache. Initially, these symptoms led her to suspect Covid due to the intensity of her headache. Within a few days, her sore throat descended to her chest, followed by a particularly severe cough. Her symptoms emerged about a week ago, with the headache still persisting and a notably worsening cough over the past couple of days, causing frequent bouts of coughing. Yesterday, she began to notice discomfort in her neck, and today, the left side of her neck feels notably tender and rigid. Flexing her neck is quite painful. She seeks advice on whether this neck discomfort could be a result of muscle strain from coughing, the presence of swollen lymph nodes (although she questions why this symptom would manifest now rather than during the initial phase of her illness), or if it might necessitate an emergency visit to rule out meningitis.

Understanding a Cyst on the Labia Minora
Greetings, medical professionals. I’m a 56-year-old female and recently, following an ultrasound examination, it was revealed that I have a cystic lesion located on my left labia minora, measuring approximately 1.4 x 1.2 cm. It has now been eight weeks, and I’ve tried various home remedies without any success. I first became aware of the cyst after using vaginal estrogen cream for a week. Currently, I am on a five-month waitlist to consult with a gynecologist, but the doctors are unable to confirm whether it is a Bartholin cyst. I am feeling quite anxious about the nature of this cyst. While it is not causing pain, the initial week was uncomfortable, making walking challenging. I’ve noticed that it tends to become irritated after consuming coffee or sugary foods. I would appreciate any recommendations you might have, including the use of tea tree oil or castor oil, which I’ve seen suggested in menopause discussions. Thank you very much for your assistance!
Navigating Mild Chronic Inactive Gastritis with Digestzymes
At 22 years of age, I'm a male standing at 5'5" and weighing 110 pounds. Recently, I was diagnosed with mild chronic inactive gastritis. My dietitian, who has expertise in gastrointestinal (GI) issues, recommended I try a supplement called Digestzymes. Currently, I experience a sensation of air trapped in the upper part of my stomach, particularly around my ribcage, which seems to worsen when I consume excessive amounts of food or opt for certain types of meals. My appetite is quite diminished, making it challenging for me to maintain a sufficient dietary intake. Consequently, my weight loss has become a concern due to the limitations imposed by both my diet and my ability to eat more. The diagnosis of my gastritis indicates it is mild and inactive. My previous GI specialist confirmed its mildness, showing me images that depicted only very faint red lines, which were difficult to discern. When I inquired about the loss of appetite, he admitted he was uncertain about the cause. This left me questioning whether my symptoms were truly linked to the gastritis. Fortunately, I don’t experience any pain, burning sensations, or cramps. However, I do encounter lower GI disturbances characterized by alternating constipation and diarrhea, largely influenced by the foods I consume. My stools are typically yellow and well-formed, though inappropriate food choices can lead to loose stools. Suspecting Exocrine Pancreatic Insufficiency, my dietitian has me using the Digestzymes supplement brand, which comprises ingredients like pepsin, betaine HCl, and ox bile extract. She brings 35 years of experience to her practice, and the positive reviews from her past clients suggest she effectively addresses their GI concerns through the appropriate supplements. As for a meal plan, she has yet to provide guidance as she wants to monitor my response to the enzymes first to determine their effectiveness before proceeding with dietary suggestions. However, I've noticed a concerning trend over the past three days; the air sensation in my stomach has intensified. Additionally, alongside my usual yellow stools, I've observed a yellowish-orange sludge. This occurrence isn't entirely new to me—it happened months ago during flare-ups of loose stools, where I also noted similar sludge post-episode. Now, this yellowish substance is appearing with my formed stools, though this has only been evident in the mornings for the last two days, and it feels somewhat sticky as well. Given these developments, I’m unsure if I should continue taking this supplement or if it is contributing to my discomfort. What should I consider?
Seeking Insight on Ongoing Headaches and Memory Issues Despite Normal MRI Results
Hello, Reddit community! I'm a 22-year-old assigned female at birth, currently identifying as male, standing at 188 cm and weighing approximately 90 kg, residing in Australia. Since at least November 2024, I've been dealing with several health challenges. These include severe sweating, frequent icepick headaches (about 3 to 5 occurrences each day), weekly migraines, persistent pressure in my head, ongoing brain fog, debilitating fatigue, and significant memory lapses. Additionally, I often experience phantom scents, particularly food smells that are definitely not in my vicinity. After discussing my symptoms with my doctor, I underwent a blood test, had an ultrasound to check out a lump in my neck (which fortunately was benign), and completed a brain MRI. All the results from these tests came back normal. As a next step, my physician prescribed pizotifen and iptam. While the pizotifen has helped to lessen my migraines, the iptam hasn’t made much difference, and I continue to suffer from the other symptoms. I've been on testosterone for the past seven years and have been taking duloxetine, vyvanse, and catapres for around two years. I also use fexofenadine for allergies. Although I smoke cigarettes, I do not consume alcohol. Upon reviewing my brain MRI images against typical ones I found online, I can't help but feel mine appears abnormal. Do you think it would be wise to seek a second opinion about this? Thank you for any advice you can offer!
Desperate for Answers: A Health Struggle
I am a 29-year-old man who has been weightlifting since I was 18. For the past two years, I’ve been on a frustrating journey trying to understand the cause of my relentless discomfort, characterized by persistent heartburn, pressure in my sternum, and a feeling of tightness in my chest. It’s hard to pinpoint exactly what these sensations entail, but they become noticeably worse after I consume coffee. I have undergone various medical examinations, including a gastroscopy, and the results came back normal. A barium swallow test was conducted to check for a hiatal hernia or acid reflux, and those results also showed nothing concerning. Further investigations, such as Holter monitoring and an echocardiogram, yielded clear results as well. I even tried taking proton pump inhibitors, but they didn’t alleviate my symptoms and led to the development of small intestinal bacterial overgrowth (SIBO). This agony is relentless, persisting around the clock without any reprieve.
