Understanding Black Stools: Iron Supplements or Why It Might Be Serious?
Age: 35 Gender: Male Weight: 143 lbs (65 kg) I am in the process of recovering from a stomach illness that lasted for ten days, and doctors are looking into the possibility of something more serious. Yesterday, feeling fatigued, I took one capsule of ferrous sulfate (270 mg) in hopes of addressing a potential iron deficiency. My meals for the day consisted primarily of two servings of Weetbix, which are high in fiber. Upon waking, I noticed my stool had turned a very dark shade, bordering on blackish grey. This is a new experience for me. The color appeared particularly tarry on the toilet paper, raising concerns. Could this be a result of the iron supplement? I find myself quite worried. Additionally, I'm experiencing nausea, which may stem from not eating enough, anxiety, or the lingering effects of my recent gastrointestinal illness, along with an overarching sense of weakness.

The dark color of your stool, especially if it appears tarry, can be linked to several factors, including the iron supplement you've taken and potential gastrointestinal issues. It's understandable to be concerned, especially during your recovery from a recent stomach illness.
Explanation
- Iron Supplements: Ferrous sulfate can cause dark or black stools as a common side effect. This occurs because the iron itself is dark in color and can lead to changes in stool appearance.
- Gastrointestinal Issues: However, black or tarry stools can also indicate bleeding in the upper gastrointestinal tract. Considering your recent illness and current symptoms, it's essential to monitor this change closely.
- Nausea and Weakness: These can stem from several factors, including your diet, anxiety about your health, or lingering effects from your previous illness.
Next Steps
-
Monitor Your Symptoms: Keep a close eye on your stools. If the color remains dark but you are not experiencing any pain, fever, or other alarming symptoms, it may be a side effect of the iron. However, if it persists, worsens, or is accompanied by other concerning symptoms (like severe abdominal pain or vomiting blood), increase the urgency to seek help.
-
Stay Hydrated and Eat Small Meals: Make sure to drink plenty of fluids and try to eat small, frequent meals that are easy on your stomach. This can help reduce nausea and provide some energy.
-
Document Your Health Changes: Consider keeping a note of any changes in your symptoms, including stool color, frequency, abdominal pain, or anything else unusual. This information can be helpful for your healthcare provider.
-
Follow-Up with Your Doctor: Given your previous gastrointestinal issues and your current symptoms, it is crucial to check in with your healthcare provider if the symptoms do not improve over the next few days or if you develop any new symptoms.
Remember, while iron supplements can cause dark stools, it’s always best to err on the side of caution, especially with your health history. Stay proactive and take care!

Tragic Situation Surrounding a Benadryl Overdose
Hello everyone. I’m reaching out because my younger sister, who was just 14 years old, tragically ended her life last night using Benadryl. I’m here seeking insight into her situation, and while I don’t need condolences, I appreciate any expressions of sympathy that may come my way. What I truly seek is raw, unfiltered information about what she may have experienced. Details: (I lack medical knowledge, so this information may not be crucial) - Female, age 14 - Height approximately 5'5" (give or take) and weight around 105-115 pounds (this is an educated estimate) - Took between 160-180 tablets, totaling around 4-4.5 grams (this estimate is based on my recent purchase of the bottle and her typical usage for sleep) My questions are as follows: (Feel free to share any other thoughts as well) How much time did she have after ingesting the medication? What might her last moments have been like? Was her passing calm, or was it filled with hallucinations or confusion? Did she experience seizures, or did she simply fall asleep? These are the difficult questions that I find hard to research myself. I hope that this discussion can provide clarity for anyone who might find themselves in a similar situation someday. I’m immensely grateful for any help in advance. As I post this, I’ ll be going to bed soon and may not respond to comments unless they hold significant questions related to my inquiries, though I might reconsider that later on.
Concerns About Measles Exposure After Outbreak at Work
We have not experienced any symptoms, and both of us received our vaccinations during childhood. Recently, one of our coworkers was identified as the initial case of measles within the state and has since been hospitalized. The workplace is a smaller manufacturing facility, employing around 30 people, many of whom are unvaccinated. Given this situation, do we need to take any specific actions? Is it still possible for us to transmit the virus despite being vaccinated? We are uncertain about the necessary safety measures to adopt. Our employer hasn't communicated anything regarding the outbreak; we only learned about it when we saw our workplace mentioned in the news.
Is a Red Spotted Uvula and Fever Enough to Visit the Clinic?
I am a 30-year-old woman, standing at 5'2" and weighing 280 lbs. I smoke marijuana but do not use any nicotine or vaping products. On Wednesday morning, I woke up experiencing a painful throat. The discomfort is more pronounced when I first wake up but tends to ease up later in the day. I’ve been experiencing minimal coughing, some post-nasal drip, and a fever fluctuating between 100.8°F and 101.4°F, alongside significant fatigue. Today, I also developed headaches. I suspect that my lymph nodes might be swollen, but I'm not a health expert, so I can't be certain. I have been checking my temperature rectally, as my mother mentioned that I typically don't exhibit typical fever symptoms outwardly. Is it advisable for me to see a doctor? I worry about taking up a physician's time if this is just a viral infection. No one else at home or any of my coworkers are showing symptoms of illness.
Persistent Low-Grade Fever: Seeking Insights
Greetings everyone, I am reaching out in hopes that someone may provide insight into my situation. I am a 41-year-old female, weighing 185 pounds and standing 5 feet 2 inches tall. My current medications include Trintellix, prescribed for my depression, a low-dose statin for cholesterol management, and a multivitamin. Eight months ago, I experienced a challenging second pregnancy, which involved gestational diabetes and postpartum preeclampsia; however, those concerns are now resolved, and aside from this issue, my overall health remains stable. For the past two months, I've been experiencing a daily temperature fluctuating from 99°F to 100.2°F, which is unusual for me as my normal body temperature is typically around 98.2°F. Recently, I've had multiple atypical infections and tend to catch various illnesses from my son, who is in daycare. It’s noteworthy that I tend to contract infections even when my husband remains unaffected. In the last six months, I've required antibiotics on four occasions for ear infections, including one for a dental infection and several associated with the onset of these persistent fevers, aimed at addressing a possible general infection. Blood tests examining autoimmune markers, thyroid function, iron levels, and other general indicators have all returned normal results, with the exception of Epstein Barr, which confirmed I have been exposed and developed considerable antibodies. Dental infections have been ruled out as well. Apart from frequent illnesses and recurring ear infections, I have no additional symptoms to report. With my postpartum period at eight months now, my next steps involve consulting with specialists in infectious diseases and ear, nose, and throat (ENT) worries. I am open to any suggestions or thoughts on potential avenues for further investigation regarding my ongoing fever. Thank you for your help!
Managing Fever with NAFLD
At 31 years old, I've been dealing with some health challenges. In September, I discovered I had non-alcoholic fatty liver disease (NAFLD) due to abnormal enzyme levels revealed in an ultrasound. Although my latest results show a decrease, my enzyme levels remain somewhat elevated, with a moderate accumulation of fat noted. My doctor advised against using acetaminophen for pain relief. Interestingly, my father, who has a more severe case with significantly higher enzyme levels, was allowed to use acetaminophen but not ibuprofen. Since my diagnosis, I've avoided both medications. However, I am currently suffering from a cold accompanied by a fever of 100.2 degrees, which is quite uncomfortable. I reached out to my healthcare provider for advice, but since it's late at night, I probably won't receive a response until tomorrow. For context, I am on a treatment regimen that includes 20mg of Abilify and 50mg of Pristiq, and I do not consume alcohol. Today, I also took Sudafed PE twice to help with my symptoms.
