Could Two Weeks of Wild Blueberries Lead to Dark Stools?
Warning: Discussion about stools ahead. F20. Since June 14, I’ve been snacking on wild blueberries (don’t inquire why) and have noticed my stools have taken on a dark hue. It’s hard to determine whether it’s a deep brown or more of a black shade. The consistency is solid, and I’m not experiencing any issues with bowel movements. Overall, I feel perfectly fine and haven't noticed any changes in my well-being. My blood pressure readings have also remained stable and in the normal range.

Eating wild blueberries for two weeks can indeed lead to darker stools due to their natural pigmentation. While this may cause some concern, it is generally harmless, especially since you're feeling well and have no changes in bowel habits.
Blueberries contain anthocyanins, which give them their deep blue color. These pigments can be excreted through your stool, resulting in a darker appearance. It’s good to know your stools are solid, and you haven't experienced any discomfort or changes in your overall health.
Next Steps:
-
Monitor Your Stools: Keep an eye on the color and consistency of your stools over the next week. If they continue to be dark but you remain symptom-free, it’s likely just the effect of the blueberries.
-
Stay Hydrated: Maintaining good hydration helps with digestion and stool consistency, so make sure to drink plenty of water.
-
Assess Dietary Changes: If you introduce any new foods, note how your body reacts. If you reduce the amount of blueberries you consume, observe if there is a change in stool color.
-
Seek Medical Attention if Necessary: If you notice any concerning signs, such as persistent black stools, blood in your stool, significant stomach pain, or any other unusual symptoms, it would be wise to seek help.
Continue enjoying your blueberries, but keeping an eye on your body's responses is always a good practice. Let me know if you have any other questions!

Worried About My Mole
I’m a 29-year-old female, standing at 5’2” and weighing 161 pounds. I’ve scheduled a dermatology consultation, but the wait is three months long. This mole has been a part of my life for as long as I can remember—certainly since my childhood. Over the last few years, I’ve struggled with considerable health anxiety, and my worries have now shifted to this mole. Although it doesn't cause any pain or itching, I'm uncertain if its appearance has changed over time since it’s located on the back of my neck. The duration I've had it is clear, but I'm questioning how concerned I should actually be about it.
Can I Catch Rabies from a Stray Cat?
Hello, I'm a 25-year-old woman, standing at 5'9", and I've encountered a charming outdoor cat in my boyfriend's neighborhood. This feline is adored by the locals for his affectionate nature, though I believe he's still quite young, having only appeared here in the past few months. During my visits to my boyfriend’s place, I've found myself petting this sweet cat, which is somewhat out of character for me; I usually exercise caution around unfamiliar animals, especially stray ones, due to the potential health risks they might pose, such as carrying diseases like rabies. However, his playful demeanor and constant purring as he nuzzled against my legs made it hard to resist. The cat has licked my hand a few times, and I even gave him some treats. He struggles a bit to eat them because of his small mouth, which led to him gently nibbling on me. Just to clarify, it wasn’t a real bite — he didn’t break the skin or leave any marks. After every interaction with him, I make sure to wash my hands thoroughly with antibacterial soap. This brings me to my concern: what are the chances that I could contract diseases from this cat, particularly rabies or other zoonotic infections? Additionally, I’ve been advocating for taking him to the veterinarian for vaccinations, but my boyfriend's father has a peculiar aversion to cats. I'm considering taking on the responsibility myself, but I'm unsure who owns this cat. Notably, he doesn’t have a collar and he is not neutered either.
Occasional Lump Discovered Beneath Scrotum
Hello everyone, I'm a 23-year-old male and I've recently experienced a peculiar situation. Over the past month or two, I've discovered a lump located at the base of my penis, tucked away within my scrotum. The odd part is that this lump only manifests when I am erect, making it quite noticeable. My estimation is that it is roughly the size of a ping pong ball, but thankfully, it doesn't cause me any pain. When I apply pressure to it, there’s a sensation that could be described as numbness, although I'm uncertain if that’s just in my head. In addition to this, I've encountered some unexpected issues with my sleep. I previously had no difficulties resting well, but now I find myself waking up every few minutes, and often I feel excessively hot and drenched in sweat. I'm unsure if these sleeping troubles are connected to the lump, but I’m primarily concerned about that when I have an erection. Can anyone share what this might be or if they’ve experienced something similar?
Understanding Lisfranc Injuries: Seeking Guidance
Hello, I need some help regarding an injury to my foot. I participate in tackle football and sustained an injury during a collision in a game. When I landed, I struck the ball of my foot with my toes curled under. I felt a significant tear at the top of my foot, and soon after, swelling occurred inside my cleat when I attempted to put weight on it. I underwent both an X-ray and a CT scan, which came back negative. Last week, I had an MRI, and my doctor has recommended that I consult a podiatrist. I have attached my MRI findings for reference. This incident took place around a month ago, and I have been using a medical boot since then. I can manage to walk in the boot now, but I cannot apply weight to the middle of my foot or walk normally due to sharp, nerve-like pain radiating through the sole. Additionally, I experience discomfort in my midfoot area. My second and third toes remain tightly pressed together and won't separate at all, even when I try to spread them using my foot muscles. I am looking for recommendations on what my injury might be, whether seeing a podiatrist is the appropriate next step, or if I should insist on an appointment with an orthopedic surgeon. Here are the MRI findings: - **MRI Left Foot** - **Comparison:** None - **Technique:** Multiplanar, multi-sequence MRI of the foot was conducted. - **Findings:** There are signs of bone marrow edema likely showing a contusion at the lateral cuneiform and base of the second metatarsal. Soft tissue edema has been detected in the area around the tarsometatarsal joints, including the Lisfranc ligament, but no complete tear of the ligament was observed. The alignment of the Lisfranc joint is intact. Also noted is focal plantar soft tissue edema involving the peroneal longus tendon where it attaches at the base of the first metatarsal. There are no tears evident in either ligaments or tendons. - **Impression:** 1. Bone marrow edema at the lateral cuneiform and base of the second metatarsal. 2. Presence of soft tissue edema in the area near the Lisfranc ligament without complete tearing of the ligament. 3. Focal plantar soft tissue edema with signs of tendinosis in the peroneal longus tendon. I would be grateful for any advice you could provide!
What Happens If My Doctor Leaves and I Get Abnormal Blood Test Results?
I’m a woman in my 30s with no significant health issues, and I neither smoke nor drink. Recently, I discovered that my primary care physician is about to leave the practice, a surprise to me, especially since we hadn’t had an appointment in a few months. Unfortunately, she was unable to answer many of my inquiries due to non-disclosure agreements. During my last visit, she ordered several blood tests, including a CBC and CMP, as I had been experiencing unusual symptoms, notably an elevated heart rate at that appointment. With her departure looming, expected before the week concludes, I’m concerned about whether anyone would reach out to discuss any abnormal lab results. I understand that transitions like these can be quite chaotic, particularly since my clinic is undergoing an acquisition. I'm anxious that important information might be overlooked or not communicated to me. If there happens to be any irregular result, how quickly can I expect to receive information? I typically avoid checking MyCHART for results without first consulting a doctor, as I fear I might misread the information and end up causing myself unnecessary anxiety. Thank you in advance for any insights!
