Mystery of Unexplained Weight Loss
Greetings, everyone. I'm reaching out to share my recent experiences over the past couple of months and seek some insights. I'm a 28-year-old male and at the end of April, my weight was 67 kg. Gradually, I've noticed a decline, and currently, my weight hovers between 63.7 and 64.3 kg. The positive aspect is that my weight seems to have stabilized instead of continuing to decrease, and I hope it remains that way. This situation has raised some red flags for me, prompting me to undergo a series of tests to uncover the cause behind this unintended weight loss. One of the primary concerns that prompted my investigation was an abnormal leptin level. For someone with a lower body weight, I should have lower levels, yet two months ago, mine was 42, and a month back, it had only dropped to 37—quite elevated. This anomaly is concerning since elevated leptin is associated with inflammation and has been linked to serious health conditions, including advanced cancer. Consequently, driven by my weight loss and the elevated hormone level, I've been undergoing thorough examinations to find potential explanations. The tests I've undergone include a colonoscopy, gastroscopy, brain MRI, an abdominal ultrasound (including the urinary tract), testicular ultrasound, transabdominal prostate ultrasound, a TRUS prostate, and both chest and abdominal X-rays, along with multiple blood, urine, and stool analyses. Testing my prostate became necessary as I’ve experienced urge incontinence for about a year and frequently find myself waking up at night needing to urinate. My PSA levels were unexpectedly high for my age, measuring at 1.57, 1.43, and 1.63 over the past month. As for my test results, the concerning findings are highlighted below: - Significantly high leptin levels. - A PSA that is elevated for my age, with a free PSA ratio of only 14%, although the TRUS results indicated no abnormalities, just fibrosis in the prostate, suggesting past inflammation. - Diagnosis of duodenitis and esophagitis stemming from GERD. The rest of the results came back normal. This lack of clarity regarding my weight loss is perplexing. I have not altered my lifestyle or eating habits, so this unexpected change is baffling. I'm contemplating requesting a CT scan of my abdomen and pelvis to rule out anything that might have slipped through the cracks of my previous tests. Do you think it would be beneficial to pursue a CT scan? I wonder if it could reveal any issues with the pancreas or small intestine, which the ultrasound might not completely capture. I understand that at 28 years old, the likelihood of having advanced cancer causing weight loss is quite low, but this is the first time I've experienced such a decline in weight without a clear reason, which is a bit alarming. Although this period has been stressful, the weight loss began occurring before that, which leads me to believe that stress might not be the culprit, as my eating patterns remain unchanged. I appreciate any thoughts or advice you may have, and I apologize for the lengthy message!

It’s understandable that experiencing unexplained weight loss and concerning test results can be alarming. Elevating leptin levels and changes in PSA, coupled with gastrointestinal issues, requires careful consideration to ensure you are addressing your health appropriately.
Key Points:
- You're experiencing unexplained weight loss, elevated leptin, and slightly elevated PSA levels.
- You've undergone extensive testing but still feel uncertain about the root cause of your weight loss.
- You are considering further investigation with a CT scan.
Explanation:
Unexplained weight loss can be caused by various factors, including gastrointestinal issues (like your diagnosed duodenitis and esophagitis), endocrine imbalances, or even psychosocial stressors, although you've indicated that stress doesn’t seem to be a contributing factor in your case. Elevated leptin can indeed reflect complex metabolic or inflammatory processes, and PSA results in younger men can sometimes be challenging to interpret without accompanying signs of prostate issues.
Given the extensive tests you've already completed, a CT scan can be a beneficial next step. A CT scan of the abdomen and pelvis can provide a more detailed view of internal organs, including the pancreas and small intestine, identifying any underlying issues not visible through other imaging techniques.
Next Steps:
-
Consider Requesting a CT Scan: Discuss with your healthcare provider the potential benefits of a CT scan to further investigate your abdominal and pelvic regions. It can help rule out or confirm concerns about internal organs.
-
Monitoring Symptoms and Weight: Keep tracking your weight closely and note any additional symptoms, such as changes in appetite, digestion issues, or new physical symptoms (fatigue, pain, etc.). This information can be useful for your healthcare provider.
-
Review Dietary Habits: Although you mentioned no changes in eating habits, consider maintaining a food diary for a couple of weeks to ensure you're getting adequate caloric intake and nutrients. Sometimes, even unintentional subtle changes can affect weight.
-
Consult Your Doctor About Leptin and PSA: Discuss the implications of your elevated leptin and PSA levels with your doctor to understand what further evaluations or monitoring might be prudent.
-
Seek Support: In times of uncertainty, talking about your concerns with a trusted friend or a mental health professional can also provide support and help alleviate some stress.
Reassurance:
While it's good to be proactive, many conditions can cause weight changes that aren’t serious. Trust your instincts and keep communicating with your healthcare team about your concerns. You're not alone in navigating this situation.

Severe Pelvic Pain and Exhaustion: Should I Seek Emergency Care?
Hello everyone, I'm hoping to gain some insights regarding my recent health issue and whether a trip to the emergency room is warranted. I’m a 34-year-old female, relatively healthy and active, especially enjoying running. However, something unusual occurred after intimate relations with my husband—everything felt fine during that time. I then settled down to use my red light therapy device, a routine part of my day. Just a few minutes in, I was overwhelmed by a sudden wave of intense cramping and excruciating pain that brought me to tears. It felt as if there was a massive air bubble or pressure within my pelvis, vagina, and rectum, as if something was obstructed. The slightest movement triggered a piercing pain radiating through my rectum, tailbone, and uterus. I ended up on the floor, crying and grappling with the discomfort for about half an hour. Gradually, the pain began to subside, becoming more concentrated in my rectum and vagina, allowing me to get up and fetch my glasses and a glass of water. If the severity of the pain had persisted, I would have sought immediate medical attention without hesitation. However, now I find myself uncertain about the next steps. I still experience some discomfort, particularly when straining during bowel movements, though urination was normal. There’s a crampy sensation in my uterus and a lingering discomfort when I exert pressure as if to relieve myself. I'm feeling quite fatigued; my legs seem heavy and somewhat tingly, and there's also a touch of nausea. For reference, I take spironolactone and levothyroxine, and my medication routine has remained unchanged. Would you recommend going to the emergency room, or should I wait and see how things progress? I’d prefer to avoid the high costs of an ER visit if it’s not absolutely necessary.
Understanding Discoloration on the Penis: What to Know
As a 30-year-old man who is uncircumcised, I have noticed significant discoloration on my penis. I'm uncertain if this is a common occurrence or a cause for concern. I'm considering sharing an image in the comments for further clarity, but I'm primarily interested in understanding normal variations or issues related to this skin change. Is such discoloration something others have experienced?
Diagnosis of Complete Bilateral Duplicated Ureters in a 34-Year-Old Female
I am a 34-year-old female weighing 135 pounds and standing 5 feet 6 inches tall. Recently, during a surgical procedure for endometriosis, I was diagnosed with complete bilateral duplicated ureters, leading to a total of four functional ureters. Interestingly, I have not experienced any notable or concerning symptoms prior to this discovery. It’s worth mentioning that this condition was not identified during a previous kidney ultrasound conducted to assess other potential issues, particularly given my history of having a complete septate uterus. From my research, it seems that such an anomaly is often diagnosed during childhood, which complicates my search for an adult specialist who can offer appropriate care and monitoring for this condition.
Are My Troponin Levels Within Normal Limits?

I smoke nicotine, do not take any medications, and have been experiencing persistent headaches and chest/arm discomfort for the past month, which began after the birth of my first child in May 2024. I previously detailed my symptoms in another post if you're interested in a more comprehensive overview. As for my troponin levels, here are the results: Is this result considered typical? Troponin I (High Sensitivity) Normal range: below or equal to 34 ng/L; My result: <3 ng/L.
Concerns About Health: High Calprotectin Levels and Anxiety
At the age of 21, I find myself overwhelmed with fear regarding my health. My recent calprotectin test results were alarmingly high at 224, which has led me to schedule an appointment with a gastrointestinal specialist next month. Although my doctor noted that she would not have referred me to a specialist had I not exhibited such a high level of anxiety, I can't shake my fears. I understand that anxiety and stress can contribute to gastrointestinal issues, but the severity of my symptoms—mucus in my stool and diarrhea—has me worried. Worst-case scenarios have been mentioned, including Crohn's disease, which adds to my distress. Not too long ago, I underwent a blood test for the presence of blood in my stool, and thankfully the results came back negative. Despite this, I can’t help but feel plagued by doubts, wondering if perhaps there was an error in either the blood test or the stool test, leading me to fear that I might actually be suffering from anemia due to a bleeding tumor. To add to my concerns, there is no family history of colon cancer in my immediate relatives. There were a couple of family members who succumbed to cancers related to smoking and alcoholism (specifically throat and lung cancer), and a distant cousin who faced leukemia at a similar age to mine. Yet, the absence of direct cancer links in my family does little to quell my mounting anxiety.
