Is Dark Stool a Cause for Alarm?

6/17/2025, 2:40:25 AMMale25-34

User Profile: 28 years old, assigned male at birth, 5 feet 2 inches tall, receiving 0.5 cc of testosterone cypionate weekly, non-smoker. To provide some context, this situation began two days ago. Initially, I assumed I was enjoying a can of lemon-flavored San Pellegrino sparkling water that might have had a little too much lemon juice in it. However, I later discovered that a slice of lemon had been marinating in that can for quite some time. Admittedly, my actions weren’t the most sensible; I figured the worst-case scenario would be that the drink had simply lost its fizz. So, I had a can on my desk that I found overly sour. When I finally decided to take a sip, I was surprised—what I tasted was somewhat sweeter than I expected. It didn’t taste bad, just less alarmingly sour than before. I thought perhaps my initial reaction had been overly critical. I continued to enjoy what I presumed was flat sparkling water, but as I neared the bottom of the can, I encountered something solid. To my horror, I initially imagined it to be an enormous mass of mold; however, it turned out to be a very moldy piece of lemon, green and slimy in appearance. In response to this unsettling discovery, my first thought was to have a quick double shot of whiskey, but as I was working, I instead chose to drink a glass and a half of saline solution. Overall, my evening passed without incident; I didn’t feel nauseated or unwell. The following day, I did indulge in that double shot of whiskey for good measure, then took a nap before heading to work. When I awoke, I was sober and experienced no hangover, feeling perfectly fine for the rest of my day. Today, I again felt normal, with no unusual symptoms. However, after eating, I noticed that my stool was darker than usual. While it might be a bit of an exaggeration to describe it as completely black, it definitely is quite dark. Is this something I should be worried about? I don’t have any stomach cramps, nor do I have a fever or any other peculiar symptoms. I appreciate any advice you can offer.

Dark stool can be concerning, but in your case, it may not indicate a serious problem based on your current symptoms. It's important to consider a few factors that can lead to darkening of stool, including dietary changes, including the consumption of certain foods or beverages, as well as medications and dehydration.

Explanation:

  1. Dietary Contributions: Foods like black licorice, blueberries, beets, and certain supplements (such as iron or bismuth, often found in medications like Pepto-Bismol) can darken the stool. The moldy lemon and other food choices you’ve described, along with the whiskey, may also contribute to this change.

  2. Gastrointestinal Health: Dark stool can sometimes indicate bleeding in the upper gastrointestinal tract, giving the stool a black, tarry appearance. However, without symptoms like stomach pain, nausea, vomiting, or fever, your risk seems lower.

  3. Testosterone Influence: Since you’re receiving testosterone cypionate, it's also worth noting that some hormonal changes might affect digestion, though this is less common.

Next Steps:

  1. Monitor Symptoms: Keep an eye on your stool color for the next few days. If it returns to a normal brown color, this is a good sign. Note any other changes in your body or digestion.

  2. Hydrate Well: Ensure you’re drinking enough fluids. Staying hydrated can help maintain regular digestion and stool consistency.

  3. Avoid Irritants: You might want to limit consumption of alcohol and any highly acidic foods for a short while to see if your symptoms resolve.

  4. Seek Immediate Help If Needed: If your stool remains dark for more than a few days, or if you develop new symptoms like severe abdominal pain, vomiting blood, or any other concerning signs, you should seek medical attention.

In summary, given your lack of severe symptoms and feeling generally well, the dark stool may be a temporary issue related to dietary changes. Just keep monitoring your body, and let me know how things progress!

Struggling with Constipation for Over a Week

I'm posting on behalf of my partner, a 30-year-old transgender man, as he doesn't currently have a Reddit account: Regarding his medical background, he has been on testosterone therapy for two years and has been prescribed Adderall since he was six to manage his ADHD. He is somewhat susceptible to constipation and bloating, but the current situation has escalated to a new level of discomfort. Standing at 5’3” and weighing 145 pounds, he previously weighed about 225. He also battled diabetes, which has been under control for over two years now. For the past week, he has experienced significant bloating and has found it nearly impossible to have a bowel movement without the aid of laxatives. After trying Miralax for a few days without much relief, we visited a patient care facility where they suggested magnesium citrate without conducting an X-ray. A blood test revealed no concerning antibodies indicative of intestinal damage, but the magnesium citrate primarily helped him pass mostly liquid stool mixed with a few solid fragments. After enduring two days of intense abdominal pain, we went to the ER. There, an X-ray showed no blockages, but indicated a moderate buildup of stool. They prescribed Senokot. He has also been using enemas to stimulate bowel movements and has continued taking Miralax daily. He has been on Senokot for the last two days but hasn't combined it with the magnesium citrate. His intake includes Greek yogurt, adequate hydration, a maximum of two cups of coffee daily, and he has been walking on a treadmill, yet the bloating continues unabated. He suspects that his primary fiber source, keto bread, may be worsening the issue, so he has refrained from it for several days. We’re considering incorporating a small amount of prune juice into his regimen, mindful of not overwhelming his system with fiber, which could be counterproductive. Overall, his diet is relatively healthy, but he’s found it challenging to eat comfortably due to the bloating. So far, he has had one normal movement induced by an enema and the loose stool resulting from the Miralax, so it’s clear he isn’t completely obstructed. We would greatly appreciate any insights or recommendations to help restore his bowel health to normalcy.

Dealing with a Stomach Irritation After Vomiting

After a meal, I ended up vomiting, unfortunately not realizing that quite a bit landed on my blanket. Following that, I went to sleep and woke up to an intense burning sensation in my abdomen, discovering that remnants of vomit were stuck to my bare skin. I might have slept for around thirty minutes, or it could have been a few hours—I really wasn't keeping track of the time. While I’ve already cleaned up the mess, my skin is now red and noticeably irritated, causing significant discomfort. What further steps should I take to alleviate this condition? F24

Understanding Hand Weakness

I'm a 20-year-old female, and I've been experiencing sensations of weakness in my hands. While I’m able to lift things and can still exert a decent grip—similar to how I grip with my dominant right hand—the feeling in my left hand is different. It seems noticeably weaker, and objects sometimes feel heavier than usual. I’m curious about what it actually means to have a "weak" hand. Does this sensation indicate a significant lack of strength, or could it merely be a perception issue? I have been noticing fluctuations in the weakness of my limbs over the last few days. Just two days ago, the weakness was in my right hand, accompanied by a tingling sensation. Now, my left hand and left foot feel the same, and occasionally, I notice some weakness in my right foot as well. I'm feeling anxious about these symptoms and would like some guidance on what I might be experiencing.

Rapid Weight Loss and Persistent Nausea After Eating: Seeking Solutions

I’m an 18-year-old recent high school graduate facing a troubling issue over the last year—significant weight loss. Despite only nibbling on food, I experience intense nausea afterward. Though I don’t participate in structured workouts, I remain active with friends, enjoying activities like beach outings, soccer games, and casual walks. I occasionally smoke cannabis, and I suspect it might be impacting my appetite. However, even when I completely avoid smoking, my intake hasn’t improved to what I believe it should be. My main concern is the ongoing weight loss; it worries me if this trend continues.

Understanding the Intense Hunger After Alcohol Consumption

I'm a 24-year-old male weighing 230 pounds and standing at 5'11". I have a history of generalized anxiety disorder, panic disorder, and depression. I typically drink in social settings about 2 to 3 times monthly, consuming around 4 to 6 beverages each time. This pattern has persisted since early 2023. Regardless of whether I have 2 or 10 beers, I inevitably experience an overwhelming hunger for the subsequent 2 to 3 days, significantly increasing my food intake. To keep track of my health, I use a blood sugar monitor, and my readings during these post-drinking days remain normal. For instance, my fasting glucose levels range between 88 and 93, while after eating, they rise to between 101 and 125. Most of the day, my levels return to the mid-80s unless immediately following meals. These readings appear consistent, irrespective of my alcohol consumption. The craving I experience is quite intense, almost aggressive, creating a sensation where I feel an urgent need to eat. I suspect that my medication, Lexapro, may have contributed to this issue, especially since it started to emerge towards the end of my time on it. During my time on Lexapro, I gained around 35 pounds, which adds to my concern.
