Frequent Dark Brown Discharge: What's Happening?
Hello! I'm a 22-year-old female, and for the past year, I've been experiencing unpredictable menstrual cycles. After getting a copper IUD in January 2023, my periods initially became extremely heavy and excruciating, but they've since transitioned to being quite light, although they still last for the same duration. Last summer, I began taking spironolactone at a dosage of 50mg to manage my acne, and I suspect that it may be contributing to the irregularity of my cycles. Currently, my menstrual cycles fluctuate significantly, ranging from every 11 days to over 40. Nevertheless, I've been averaging cycles every two weeks for the last few months. These periods tend to be prolonged but light in flow, accompanied by a discharge that appears nearly black. Although the pain is minimal now and cramping has decreased, I experience sudden and intense bloating. I've noticed that I can gain more than 6 pounds overnight, leaving me feeling puffy and literally swollen, which feels very unusual for me. I'm generally a fit individual, having lost around 80 pounds over the past few years with regular workouts, and my body fat percentage is approximately 21-22%. You can often see my abdominal muscles. However, the bloating makes me resemble someone who is four months pregnant, which has not been an issue since I shed the weight. I'm growing increasingly frustrated with bleeding every two weeks, often more than that, and I find it incredibly difficult to predict my cycles. It has been over six months since I last experienced a regular period. What could be happening?

It sounds like you're experiencing quite a few changes and symptoms related to your menstrual cycles and overall health, and I understand why this is concerning. Irregular cycles, along with dark brown discharge, bloating, and weight fluctuations can be frustrating and may indicate underlying issues that deserve attention.
Main Points:
- Irregular Menstrual Cycles: Changes following your copper IUD insertion and the use of spironolactone may be contributing factors.
- Dark Brown Discharge: This often indicates old blood and can occur if your body is shedding its lining irregularly.
- Bloating and Weight Changes: Sudden bloating and rapid weight gain could be linked to hormonal fluctuations or other underlying conditions.
Explanation:
- Copper IUD Effects: It’s not uncommon for menstrual cycles to be unpredictable after getting an IUD. Initially, heavy bleeding can turn into lighter periods, but for some, this process can take time for the body to adjust fully.
- Spironolactone and Hormonal Influence: As a diuretic and androgen receptor blocker, spironolactone can affect hormonal balance and potentially contribute to menstrual irregularities, but it’s usually well tolerated for managing acne.
- Dark Brown Discharge: This color typically indicates that the blood is older and may have taken longer to exit the body, often seen in irregular cycles.
- Bloating: Hormonal fluctuations can lead to bloating, particularly around the time of menstruation. However, if you are gaining significant weight (over 6 pounds overnight), it is worth investigating further.
Next Steps:
- Tracking Symptoms: Keep a detailed diary of your menstrual cycles, discharge, bloating episodes, and any associated symptoms (like cramps, pain, or changes in weight). This will be helpful in identifying patterns or triggers.
- Diet and Hydration: Monitor your diet; consider reducing sodium intake to help mitigate bloating. Staying well-hydrated is crucial, but consider discussing electrolyte balance.
- Identify Triggers: Note any specific foods or activities that worsen the bloating or irregular cycles. Sometimes diet changes can exacerbate bloating.
- Consider Hormonal Evaluation: Hormonal imbalances can be evaluated through a blood test, so thinking about this may help understand any underlying conditions related to your thyroid or other endocrine issues.
- Follow-up: As your symptoms have persisted and seem quite distressing, stay engaged with your healthcare provider. Discuss your diary and any concerns about the copper IUD and spironolactone's impact on your cycles.
Understanding your body and its responses can take time, so being patient and proactive is important. It sounds like you’re doing a great job managing your health overall, and addressing these concerns will be a part of that journey. Please let me know if you need more details or specific suggestions!

Should I Be Concerned About My Thyroid Issues?
At 27 years old, I have been experiencing various unusual symptoms intermittently over the past five years. These include sudden swelling of my thyroid glands, which occurs even when I am not ill. Additionally, during my menstrual cycle or when I have a cold, I notice a pronounced lump on the right side of my collarbone, similar in size to a marble, which disappears almost overnight once my period concludes. Lately, I've also noticed swelling occurring between my left ear and jaw; when I massage this area, I can feel a fluid draining sensation. My thyroid seems to react quite noticeably during these illnesses; for instance, when I have a mild cold, it becomes prominently enlarged, accompanied by significant pain and throbbing. The most severe instance of this occurred last year when I developed pneumonia, which stemmed from a cold and lasted for three months. During this time, my tonsils became infected, and I noticed what appeared to be a goiter on the left side of my neck, slightly larger than a golf ball. An emergency room visit ensued, where IV steroids were administered, leading to a swift reduction in the swelling. Although the doctors were not particularly worried about the lump, they did inform me that my white blood cell count was notably elevated, though I confess I am uncertain about what that implies. Furthermore, I typically take a long time to recover from even common colds. My general practitioner is very attentive and ensures that I have thyroid blood tests conducted with every appointment, and these results consistently return normal. I maintain a very healthy diet, consume alcohol infrequently, and exercise moderately. Despite being slightly underweight according to health statistics, I am 5 feet tall and do not appear to be underweight. Given that my test results remain normal, I find myself questioning whether I should be more alarmed about these ongoing issues after five years of unpredictable symptoms.
Diagnosis of Cancerous GIST in the Stomach with Liver Involvement
Hello, I'm an 18-year-old female who recently received a diagnosis of a cancerous GIST that has metastasized to my liver. My hospital specialist informed me that this condition is quite rare, and I have been scheduled to see an oncologist this coming Friday. I’ve been experiencing pain and have had evidence of a tumor growing for at least five years, measuring 7 cm. I'm reaching out to see if any medical professionals might share insights on what symptoms I should be vigilant about or what I can anticipate during my appointment with the oncologist.
Concerns Regarding Blood in Urine
Male, 32 years old, 6 feet tall, weighing 11 stone. I find myself in a challenging situation and would appreciate some insights, particularly from anyone who has experienced serious dehydration or kidney-related problems. For the past month, I've been struggling with what appears to be gastritis, which has been quite intense, making it very hard to consume food or fluids. I regret not drinking enough water lately, and I'm currently making an effort to correct this. Just yesterday afternoon, I used the restroom and was taken aback to see that my urine had taken on a red-brown hue. Naturally, this was alarming, prompting me to start hydrating more diligently for the rest of the afternoon. Thankfully, all the subsequent trips to the bathroom resulted in clear urine, which was a relief. However, later I encountered another issue: I noticed small red blood clots in my urine. While not excessive, they were certainly visible and quite concerning. Overnight, my urine remained clear, and luckily, I haven’t observed any more blood clots since yesterday. I underwent a urine analysis this morning, which showed no blood present. The doctor seems unconcerned, and I am trying to come to terms with that. On one side, the immediate scare with the red urine and clots appears to have resolved, and the latest test results are normal. On the flip side, the intensity of the initial symptoms still lingers in my mind and has left me anxious. So, I turn to you all: Should I pursue a referral to a urologist, or could this situation merely stem from significant dehydration exacerbated by my ongoing gastritis? I find myself conflicted between accepting the doctor’s evaluation and feeling the need to advocate for further investigation based on my experiences. Any reflections, shared stories, or recommendations on how to discuss this with my physician would be incredibly helpful. Thank you in advance for your assistance.
Should I Be Concerned About Neck Pain and Numbness in My Arm and Leg?
Subject: 34-Year-Old Male, Weight: 73 kg (Background Information: I had been undergoing testosterone replacement therapy (TRT) while my testosterone levels were normal, but I discontinued the treatment approximately three months ago due to experiencing vision problems and sharp headaches.) Three days ago, while taking a walk, I suddenly experienced intense pain in my neck. This discomfort was quickly followed by numbness exclusively in my left leg, which also felt weak for a brief moment, making it difficult for me to control its movement. Now, after three days, the neck pain persists but has slightly improved. However, this morning I noticed similar symptoms in my left arm; it became numb and also exhibited a short-lived weakness that hindered my ability to move it normally. Even after several hours, there remains a slight feeling of weakness, although I can now move my arm correctly. Should I consider this an emergency situation, or is it something I can approach without immediate concern?
