Concerns Over Mom's Rising Chromogranin Levels: Should We Worry?
Approximately nine years ago, my mother, aged 63, was diagnosed with carcinoid tumors located in her small intestine. Following her diagnosis, she underwent surgery to remove these tumors, but by that time, the cancer had already spread to her lymphatic system. Approximately seven years ago, it extended to her liver as well. She has been receiving Octreotide injections ever since, which have effectively controlled the growth of new tumors, and her latest CT scans indicate no new development since she started this treatment. Despite this positive news, she continues to experience symptoms associated with carcinoid syndrome and potential side effects from the initial surgery, such as flushing, diarrhea, weight gain, and a lack of appetite. Fortunately, these symptoms have remained stable without significant improvement or deterioration. However, while her scans are reassuring, her laboratory results raise some red flags. For over a year, her chromogranin levels have been on a concerning upward trajectory with each doctor's appointment. Her latest test results show a chromogranin level exceeding 300, which is a noticeable jump from around 250 just four months prior, and 225 four months before that. Her doctor, who has a tendency to minimize her concerns, remarked nonchalantly about the abnormal levels, stating, “You have cancer. It’s expected that your levels would be off.” I’m fully aware that her levels will not be normal. However, it’s alarming that they have surged by more than 30% in just eight months, particularly after being stable for so long. That said, I do not possess medical expertise, nor do I have a clear understanding of what constitutes a normal range for someone like my mother. Is this rise in chromogranin levels typical? Could it signal the presence of additional tumors that might not have been detected in the CT scans? If there are valid reasons to be concerned, what inquiries should we pursue, and what specific tests might we consider?

It’s understandable to be concerned about your mother's rising chromogranin levels, especially after her history with carcinoid tumors. Elevated chromogranin A (CgA) levels can indeed help monitor the presence of neuroendocrine tumors, but interpreting these results requires careful consideration.
Key Insights:
- Chromogranin A Levels: Chromogranin A is a marker used to evaluate neuroendocrine tumors. While levels can fluctuate, a steady or slight rise can be concerning, especially considering your mother’s medical history.
- Potential Indications: An increase in CgA could suggest possible tumor progression or new tumor development, but it can also be affected by other factors such as renal function, certain medications, or additional health issues.
- Stability in Imaging: The absence of new tumors in the CT scans is encouraging, but you rightly note that an increase in CgA merits further investigation.
Next Steps:
-
Request Detailed Explanation: Encourage your mother's healthcare provider to provide a clear rationale for the rising CgA levels, especially in light of her stable imaging results. You can ask about the significance of the specific rise and what it could mean for her treatment plan.
-
Consider Additional Testing:
- Repeat Chromogranin A Test: Conduct additional CgA tests to see if the trend continues.
- Evaluate Other Biomarkers: Discuss the possibility of testing for other markers related to neuroendocrine tumors, such as 5-Hydroxyindoleacetic acid (5-HIAA) or serotonin, which can provide more insight.
- Imaging Studies: Ask if further imaging, like a PET scan, is warranted to check for small or unseen tumors.
-
Symptom Management: Since your mother is experiencing symptoms related to the carcinoid syndrome, working with her doctor to optimize management strategies for these symptoms—such as medications for diarrhea or appetite stimulation—could improve her quality of life.
-
Consider a Second Opinion: If you feel that her concerns are being minimized, seeking a second opinion from a neuroendocrine tumor specialist or a center that specializes in carcinoid tumors may provide a more thorough evaluation and outline a well-rounded treatment approach.
-
Documentation and Monitoring: Keep detailed records of her symptoms, treatment responses, and lab results. This information can be invaluable for her healthcare team in evaluating her condition and monitoring any changes.
Conclusion:
Your concern for your mother's health is valid, and staying informed and proactive is important. By seeking clarity from her healthcare provider, considering further testing, and ensuring effective symptom management, you will help support her ongoing care. Keep the lines of communication open with her medical team, and do not hesitate to advocate for further exploration of her condition.

Strange Jelly-Like Substance Observed from Wound
I’m a 21-year-old female living with an auto-inflammatory condition known as hidradenitis suppurativa (HS). Recently, I've experienced a concerning issue with one of my wounds. This particular wound causes significant pain and excessive bleeding. However, whenever I attend to it, I tend to find this unusual jelly-like substance present within it. Interestingly, this phenomenon has only occurred with this one wound and not any of the others I have. The bleeding seems to persist until I manage to remove this jelly substance, after which it typically slows down and comes to a halt completely. I’m seeking insights into what this might signify so that I can effectively discuss it with my healthcare provider.
Battling Chronic Nausea and Vomiting for Over Two Years
For the past two years, I (age 26, female) have been enduring an incredibly challenging health situation. I experience intense nausea daily and find myself vomiting numerous times, with almost nothing providing relief. To provide some background, I’m from West Texas and I currently weigh around 190 pounds, standing at 5’7”. Initially, my weight was about 211 pounds when these symptoms began, and it fluctuates frequently between 190 and 225 pounds. I engage in vaping and consume THC. Previously diagnosed with hypothyroidism, my condition seemingly resolved, according to my healthcare providers. Additionally, I have polycystic ovarian syndrome (PCOS). I have consistently faced irregular bowel movements, with stools that are loose and sometimes appear to have mucus. Compounding my struggles, I've also suffered from migraines. I have had an IUD for over five years, experiencing two insertions of the Kyleena device. In December 2022, my battle with health took a severe turn when I was diagnosed with stage 4 Hodgkin’s Lymphoma, requiring chemotherapy treatment, specifically AVBD (Apologies for not recalling the exact medication names). By July 2023, I had fortunately achieved remission. However, after reaching remission, my vomiting worsened, transforming from primarily white foam to a mixture of 80% bile, any food I attempt to consume, and still white foam. This intense vomiting, accompanied by significant pain in my upper back, escalated to more than eight episodes daily by November 2023. At that time, THC seemed to be the only avenue for me to retain any food. During this tumultuous period, I consulted various doctors who, after confirming I wasn’t pregnant, attributed my symptoms to Cannabinoid Hyperemesis Syndrome (CHS). Immediately, I ceased THC consumption for over six months, yet the vomiting continued unabated. Each time, doctors would prescribe ondansetron, regardless of my claims that it provided no relief. I experimented with various diets recommended by medical professionals, but there were no improvements in my condition. Eventually, I obtained a referral to a gastroenterologist who intended to perform an endoscopy. However, the procedure was prohibitively expensive even with insurance, and thus was never conducted. This doctor also ordered blood tests to rule out several gastrointestinal disorders, such as Crohn's disease, Irritable Bowel Syndrome (IBS), and gluten sensitivity, but all results came back normal. Afterward, I had another appointment with a different gastroenterologist, but the doctor failed to meet with me. Instead, a nurse informed me that the doctor had merely recommended promethazine without conducting any tests or scheduling further visits. When I mentioned the possibility of gallbladder issues, the doctor laughed dismissively at my suggestion. Discussing my situation with my oncologist, he suggested that my heightened sensitivity to food odors stemmed from my chemotherapy experiences while I was working in fast food. While food smells indeed affect me, I'm primarily triggered by medical scents such as rubbing alcohol and cleaning agents. This ongoing ordeal has been overwhelmingly distressing. I now experience episodes of vomiting accompanied by bright red blood, presumably due to a throat tear. When I first encountered this troubling symptom, I consulted a doctor who appeared unfazed and prescribed a promethazine suppository, which does help but makes me extremely drowsy. My nausea persists nearly around the clock, often feeling as if there’s a heaviness in the upper part of my abdomen. I frequent urgent care facilities when my symptoms intensify, only to be met with minimal assistance since this is a chronic issue. Currently, I lack a primary care physician. Whenever I sought one, I encountered skepticism regarding my condition, with some healthcare professionals implying that I was exaggerating my symptoms. Though many physicians who do take my situation seriously seem baffled, I've lost count of the diverse medical experts I've consulted about these ongoing issues. If anyone has insight or suggestions, I would genuinely appreciate it. I can share my latest bloodwork results if that would be helpful—just let me know!
Strange Stomach Sensation Leading to Waking Up
Greetings. I'm a 36-year-old male, standing at 172 centimeters and weighing 90 kilograms. I don't take any medications, nor do I smoke. I've been living with diastasis recti for several years now, and I may also have irritable bowel syndrome (IBS). Additionally, I deal with fatty liver and kidney stones, though I assume these last two conditions are not related to my current concern. Occasionally, I experience a peculiar sensation that jolts me awake; it feels like a quick pulsing in my stomach. I’ve noticed it tends to affect the left side when I’m lying on my left side and the right side when on my right. Remarkably, it can occur even when I’m on my back. This strange feeling often escalates into a surge that fully rouses me. Alongside this, I sometimes feel prickling sensations throughout my body and fleeting lightheadedness. When this sensation disturbs my sleep while I’m turned to my side, shifting onto my back or the opposite side might alleviate it, but not always. In instances where I awaken while lying on my back, I discovered that gently pressing my hands on either side of my stomach can help, as can rising to a sitting or standing position. However, during my last two episodes—one a couple of weeks ago and another tonight—those techniques weren’t effective right away, which made me feel a bit anxious, prompting me to seek advice. Does anyone have insight into what might be going on? By the way, I’ve undergone routine ultrasound examinations of my abdomen by two different physicians during check-ups, both of whom assured me that everything appears normal, including my abdominal aorta and internal organs. They didn’t identify any issues at that time.
Understanding Tuberculosis Exposure Risk
A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.
Healing Progress Post-GBS: Toe Concerns
I am a 28-year-old male, measuring 5 feet 10 inches and weighing 131 pounds. My current medications include Fomadatine and Zyrtec, prescribed due to my ongoing battle with Chronic Gastritis and SIBO. I maintain a healthy lifestyle, abstaining from both smoking and alcohol. My health concern revolves around the toe adjacent to my pinky toe on my left foot, as well as my pinky toe on the right foot. Since August of last year, I have been on the mend from Guillain Barre Syndrome. Recently, I've noticed that at night, the skin on my feet tends to turn a reddish pink, although this usually improves after I walk around. However, two of my toes have remained red, with one appearing slightly swollen. Generally, my pinky toes are quite thick, but the condition of my left foot's toe is worrisome for me. It seems that I'm unable to upload an image to illustrate my issue.
