Unusual Grey Spot in Stool
Hello! I’m a 24-year-old female and I just discovered a grey spot in my stool this morning. This marks the second occurrence in the past few months. The last time I found one, I attributed it to my calcium supplements; however, I'm not currently taking any. At present, I routinely consume vitamin D, magnesium, and omega-3. Importantly, I’m not experiencing any additional symptoms, such as those linked to liver issues or pancreatic problems. Additionally, I’m currently on my menstrual cycle, which might be relevant. I'm simply seeking some insights into what this could indicate before I have an opportunity to consult a healthcare professional. I appreciate your help!

It's understandable to be concerned about changes in your stool, but the presence of a grey spot is often not cause for alarm, especially if you’re experiencing no other symptoms. Let's break down your situation.
Main Points
- A grey spot in your stool can be related to dietary factors, supplements, or even normal variations in digestion.
- Given your current supplements and lack of other symptoms, it may be benign, but monitoring is important.
Explanation
Stool color can vary due to many factors including food intake, medications, and supplements. While certain colors in stool can suggest specific health issues, a grey spot alone, especially without other symptoms, is typically not worrisome. Here are a few possible explanations:
- Dietary Factors: Foods like beets, leafy greens, or even certain food colorings can change stool appearance.
- Supplement Effects: Although you are not currently on calcium supplements, other supplements like magnesium may also influence digestion.
- Bile Production: Variations in bile production and digestion could lead to changes in the color or consistency of the stool.
Next Steps
-
Monitor Your Symptoms: Keep an eye on your stool over the next few days. Note any changes in color, consistency, or the presence of new symptoms (e.g., abdominal pain, changes in appetite, or unusual fatigue).
-
Hydration and Nutrition: Ensure you’re staying hydrated and maintaining a balanced diet. Sometimes, dietary shifts can reflect in our stools.
-
Log Your Findings: Consider keeping a brief log of when you notice these grey spots and any related symptoms or changes in your diet or supplement intake for discussion with your healthcare professional later.
-
Consult with a Healthcare Provider: If the grey spot persists or if you develop any additional symptoms, definitely reach out to a healthcare professional for a thorough evaluation.
It's excellent that you're proactive about your health. If you notice no further changes or symptoms, this may just be a benign fluctuation. Let me know if you have any more questions or need further clarification!

Concerns About Dark Stool: 31-Year-Old Female
I am a 31-year-old woman from the USA, weighing 145 pounds and standing 5'3" tall. My medication regimen includes Adderall, with a dosage of 25mg XR daily and an additional 10mg IR also taken once a day. I do not take any dietary supplements. Generally, I maintain a good level of health, engaging in moderate physical activity and consuming alcohol in moderation. However, during my recent vacation, my alcohol consumption has increased, though I remained in the country. Additionally, I have been using nicotine through vaping for about a year, having quit smoking cigarettes in 2019, and I do not use other recreational drugs. For the past year, I have dealt with intermittent hemorrhoids, which I haven’t sought medical advice for as they typically resolve on their own and the bleeding has been minimal. Nonetheless, I have noticed a troubling change in the last couple of days: my stool has been unusually dark and accompanied by discomfort during bowel movements. Each time, my stool has been very hard, exhibiting an almost black hue rather than the typical brown shade, and has a particularly foul odor. This is a new and concerning experience for me. Although I did take Advil after having a few drinks two nights ago, this hasn’t caused any previous issues in the past. I appreciate anyone who takes the time to read this and any insights or support offered.

Finding Primary Care: Seeking Advice
Hello everyone, I’m 22, assigned female at birth, and currently receiving outpatient treatment for depression and anxiety. Fortunately, I don’t have any other known health issues. However, I will soon be relocating and aim to establish a primary care provider to address a few symptoms I've been experiencing, such as night sweats and increased sweating during the day. I'm also looking for gender-affirming care, as I identify as nonbinary. I’m curious if it makes a difference whether I choose a family medicine practitioner or an internal medicine specialist. Moreover, does it matter if I consult with an MD, DO, PA, or NP? Since there’s a shortage of physicians in my new area, I've noticed that PAs and NPs seem to be more prevalent. Additionally, I’d love some guidance on how urgent it is for me to see a healthcare professional regarding these symptoms; should I seek help sooner rather than later? Thank you in advance for any assistance!
