Concerned About My Stool Color

4/2/2025, 4:30:21 AMMale25-34

To provide some background: I’m a 25-year-old male and I’m reaching out about a health concern shortly after noticing something unusual. Just half an hour ago, I discovered that my stool appeared to be a mix of dark and light brown, but intriguingly, it also had a greenish tint. It struck me as somewhat tar-like in texture. Today, I haven’t taken any medication aside from a Zyrtec that I ingested last night. Interestingly, I don’t feel particularly dizzy; I've had two bananas along with my coffee earlier today. The last substantial meal I consumed was around twelve hours ago. Recently, my eating habits have lacked fiber, primarily leaning towards chicken, rice, bread, and fried foods, with occasional servings of broccoli and other green vegetables. I have a colonoscopy scheduled for April 17th due to existing GERD and bowel issues, which I suspect may have been exacerbated by a bout of food poisoning. However, I’m increasingly anxious that my situation might be deteriorating. I'm seeking advice on this matter!

It's understandable to be concerned about changes in your stool, especially given your upcoming colonoscopy and history of gastrointestinal issues. The combination of dark and light brown stool with a greenish tint can be alarming, but there are various factors that could contribute to this change.

Explanation

Stool color can vary significantly based on diet, digestive health, and sometimes even medications or supplements. A greenish tint can often occur due to:

  • Dietary factors: Foods with green pigments (like spinach or other leafy greens) or artificial coloring can affect stool color.
  • Digestive speed: If food moves through your intestines too quickly, bile (which is green) may not fully break down, leading to green-tinted stools.
  • Medications and supplements: While Zyrtec typically doesn’t affect stool color, other medications can.

The tar-like texture you describe may raise concern, as it can sometimes indicate bleeding in the upper gastrointestinal tract, but this typically presents as black and sticky stools rather than a mix of colors.

Next Steps

  1. Monitor your symptoms: Keep an eye on any additional changes, such as abdominal pain, changes in bowel habits (diarrhea or constipation), or any other unusual symptoms. Tracking these will help inform your healthcare provider of your status.

  2. Adjust your diet: Start incorporating more fiber-rich foods (like whole grains, fruits, and vegetables) gradually to aid digestion and help regulate your bowel movements. This may improve the consistency and color of your stool.

  3. Stay hydrated: Ensure you’re drinking plenty of fluids, especially water. This is crucial for maintaining healthy digestion.

  4. Consider food triggers: Take note of any specific foods that might have caused the change in your stool. If you suspect recent food poisoning, try to avoid heavy or greasy foods for a few days until your gastrointestinal health stabilizes.

  5. Discuss with your doctor: If you notice any worsening of your symptoms, particularly if you begin to feel dizzy, faint, or have severe abdominal pain, it’s important to consult your healthcare provider.

It’s completely normal to feel anxious about these changes, especially with your scheduled colonoscopy. Try to focus on monitoring your symptoms and implementing a few dietary changes in the meantime. Let me know if you have further questions or need clarification!

Experiencing Clear Fluid from Ear with No Discomfort: Should I Wait for My Appointment?

I am a healthy 57-year-old female, weighing 120 pounds and standing 5 feet 5 inches tall. My daily medications include 100 mg of Losartan for effectively managed high blood pressure, 200 mg of Lyrica taken twice daily for post-herpetic neuralgia, 100 mg of Synthroid following treatment for thyroid cancer, and a combination hormone replacement therapy patch. Additionally, I take Zyrtec and Flonase every day to combat allergies. Since October, I have been dealing with persistent tinnitus in my right ear, accompanied by some pressure and a muffled sensation. Recently, I've noticed that when I speak, it feels akin to the sensation I experience when my ears clear during a flight after chewing gum—my voice sounds amplified in my head. I've scheduled an appointment with a physician's assistant in an ear, nose, and throat (ENT) office for the end of March due to my worries about the tinnitus and any potential hearing impairment. Yesterday, I noticed that my ear emitted a clear fluid. Thankfully, there was no associated pain. The fluid was somewhat thicker than water, completely odorless—unlike the unpleasant discharge I recall from my daughter's ear infections—and there was no sign of blood. Could this indicate a perforated eardrum? I suspect this might be the case, but can this occur without an underlying infection? Should I seek attention sooner than my appointment in March? I would prefer to avoid urgent care during flu season; however, if this situation is serious, I am prepared to take precautions and visit.

Understanding the Increased Pain in My Foot While Reclining

At 30 years old, I am nearing the five-week mark since undergoing surgery on my metatarsals. I've encountered a troubling issue: I can’t seem to find comfort when lying down, whether it’s with my foot raised or lying flat. My pain level escalates to a severe 10 out of 10, unless my foot is making contact with the floor or I dangle my leg off the side of the bed so that my toes touch the ground. Is this situation typical for someone in my circumstances? Are there any suggestions that might assist me in getting a better night's sleep?

Assessing My Health Concerns: How Anxious Should I Be?

I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.

Understanding Possible Seizure Triggers and Recurrence Risks

Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!

Persistent Pain in Right Shoulder and Arm After Lifting

Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!
