Inquiring About Possible Surgery Postponement or Cancellation
I’m a 42-year-old woman, standing at 5'2" and weighing 280 pounds, with a medical background that includes Type 1 Diabetes, Idiopathic Intracranial Hypertension managed by a VP shunt installed on October 24, Hypothyroidism, seasonal allergies that occasionally trigger mild asthma, anxiety, and Gastroparesis. I regularly use an insulin pump that dispenses Humalog, and monitor my glucose with a Dexcom device. Additionally, I am prescribed Synthroid, Crestor, and Luvox, with access to Tylenol, Valium, and an inhaler for asthma as needed. I am facing a revision surgery for my VP shunt, set for July 15, due to a suspected blockage, although it is unclear if it’s intermittent in the proximal catheter. I have been experiencing increased symptoms and pressure in the ventricles has returned, with visual field degradation. Life has become unbearable, especially since a lumbar puncture in April revealed an opening pressure of 30. An initial tap yielded only a few drops, while the second attempt produced nothing. A CT scan showed nothing abnormal except for the coapted ventricles on the shunt’s side, leading my medical team to conclude that a revision is necessary. Today, I attended pre-anesthesia testing. As a Type 1 diabetic with an A1C level of 8.0—attributed to struggles with insulin access and pump failures over the last three months—I have adjusted my pump settings, which are gradually improving my situation, and my endocrinologist remains optimistic. During testing, my blood pressure was recorded at 142/82 and my heart rate at 110, likely due to anxiety. The nurse practitioner overseeing my pre-op cleared me for surgery pending laboratory results. The MRSA swab came back negative, and my CBC results were normal across the board. However, my BMP raised some concerns, especially regarding my glucose level, which was 204. This isn’t unusual for the morning because of the dawn phenomenon, and I'm currently adjusting my pump settings for better control each week. All electrolyte values were within normal limits, and my BUN level was excellent. The only notable issues were an Anion Gap of 17 and a CO2 level of 18. I was unaware that I should have fasted beforehand; the last time I ate or drank was at 7 PM the previous night, with lab draws occurring around 9 AM. I have previously experienced Diabetic Ketoacidosis (DKA) and would certainly recognize if it were a concern. After testing my urine for ketones, the results were negative. My blood sugar has remained stable at around 140 throughout the day, even following a late breakfast and lunch. Aside from the complications related to my shunt, which are disrupting my daily life, I feel otherwise well. Additionally, we’ve been enduring high temperatures in the 90s with high humidity this past week, and I have a low tolerance for heat. Recently, I spent several hours outside at a birthday gathering, making efforts to stay hydrated and find shade. I suspect mild dehydration but have been consuming additional fluids to offset it throughout the day. I am not experiencing any odd breathing difficulties, cramping, or other alarming symptoms aside from the persistent neurological issues. My neurosurgeon won’t receive the test results until Thursday, while my surgery is scheduled for Tuesday. I am incredibly anxious that the results may lead to the postponement of my surgery, and no one has indicated that a retest might be necessary. Last month’s tests were all within normal ranges, albeit I have a history of slightly lower CO2 levels. Should I be worried? I am feeling panicked! The thought of enduring this for more than another week is distressing, and postponing or canceling this surgery is not an option for me. I contacted my neurosurgeon's nurse, but she couldn’t provide any assurances. I also left a message for my surgeon's physician assistant via MyChart. Please alleviate my concerns and reassure me that everything is on track!

The fact that you are not showing symptoms of DKA after confirming your ketone levels are negative is reassuring. It’s also a positive indicator that your previous tests were normal and that your surgical team is awaiting results before proceeding with surgery.
Next Steps:
- Stay Proactive: Continue to monitor your glucose levels closely. Aim to maintain your levels below 180 mg/dL, especially prior to surgery. Adjusting your insulin pump settings as needed is a good plan.
- Hydration: Focus on staying well-hydrated, particularly in this heat. If you suspect mild dehydration, ensure you're drinking enough fluids and consider electrolyte solutions if necessary.
- Anxiety Management: Engage in relaxation techniques, such as deep breathing or mindfulness, to manage anxiety. Remaining calm will help in stabilizing your blood pressure and heart rate.
- Follow-Up: Since you’ve reached out to your neurosurgeon’s team, continue to check in for updates. If you haven't received updates by your surgery date, don’t hesitate to call back for clarification.
- Prepare for Surgery: Make sure you follow any pre-surgery instructions once provided, including dietary and medication guidelines. Keeping a checklist can help minimize stress.
Reassurance:
It's completely normal to feel anxious in this situation, but your medical team appears to be attentive to your needs. Since you’ve been proactive in managing your conditions and communicating with your healthcare providers, you are taking significant and positive steps toward your surgery.
Trust in your medical team’s expertise and keep in mind that they are working in your best interest. If any urgent concerns arise or your symptoms worsen, do not hesitate to seek immediate assistance.
Keep focusing on your health and well-being, and try to find a moment of calm each day leading up to your procedure. If you have any further questions or need additional support, please share.

Ongoing Septum Wall Bleeding
**Profile:** 29-year-old male, 5'7", 69 kg, of European descent. Since December 2024, I have been experiencing continuous bleeding from both sides of my septum wall. Interestingly, there is no accompanying pain. The bleeding seems to worsen when I lie down, likely due to heightened blood pressure facilitating more bleeding in that position. At times, when the bleeding subsides, the skin along my septum peels off, almost like a layer of bloody tissue. I also wake up occasionally to find my nostrils blocked with dried blood. Throughout this challenging period, I've dealt with two staphylococcus infections in the septum area. **- Lifestyle Habits:** I consume alcohol on occasions, vape quite often, and maintain a regular exercise routine. **- Medications I Take:** I am prescribed Ritalin, Rubifen, and Adderall. **- Medical Evaluations:** Blood test results indicate: - Significant allergy to dust mites, yet I show no allergic symptoms. - No issues with blood clotting or thinning. CT Scan results reveal: - A minor deviation in the septum. Blood pressure measurements show: - Levels are within the normal range. **- Treatment Currently Underway:** I use a steroid nasal spray on a daily basis, which helps reduce the bleeding. I also apply Vaseline to the septum to alleviate the bleeding further. Topical antibiotics have been prescribed to combat the staph infections. I have undergone silver nitrate cauterization, which yielded no results. Similarly, electric cauterization also had no impact on my condition. I appreciate your time and any insights you might have!
Understanding a Mysterious Bump: Causes and Solutions
Hello everyone, I'm a 20-year-old female and I've been experiencing a peculiar bump located in the area between my thigh and groin. I can only see it when my legs are apart. The bump is movable; however, there are times when excessive movement causes sharp discomfort. I thought it was important to mention that I shave in this region. This bump has been a source of annoyance for the past two years. In my anxious attempts to find answers, I visited a doctor who conducted a swab test for HSV-2. I had to strongly encourage them to examine the bump, but thankfully, the results ruled out that possibility. After this appointment, I decided to let it be since it didn't cause me much trouble. However, reflecting on it now, I find myself wishing that it could either be drained or removed. I'm curious to hear your insights: what do you think this bump might be?
Seeking Insight on My Father’s Sudden Health Crisis: Heart Attack or Other Underlying Issues?
My father, a 56-year-old male with a medical history of diabetes and high blood pressure, experienced a tragic health event almost two years ago that raised numerous questions. Despite undergoing angiography 11 months prior, which revealed no alarming issues, his condition suddenly deteriorated. Standing 6 feet tall and weighing 113 kg, he had a familial history of cardiovascular problems, although both his parents lived into their late eighties. Previously, I shared his case in this community, but my understanding has evolved, prompting me to revisit the topic for further insights and medical perspectives. His collapse was preceded by an ECG that indicated a significant heart attack. Despite receiving immediate first aid, including atropine and CPR, none appeared to aid in his recovery. This has led me to reflect more on the symptoms he displayed over the years, which many healthcare professionals misdiagnosed or overlooked. For over a decade, my father exhibited a consistently firm and distended abdomen, often described by doctors merely as ‘gas,’ despite multiple ultrasounds yielding no evidence of fluid accumulation. Alongside this, he suffered from debilitating joint pain and a noticeable decline in the dexterity of his hands, hinting at a gradual loss of functionality. He contended with recurrent issues such as swollen lips, mouth sores, and bouts of angioedema, leading to frequent antihistamine use. Though his inflammatory markers—ESR and CRP—were elevated, tests like ANA and rheumatoid factor generated no noteworthy findings, and D-dimer levels remained normal. Severe sleep apnea compounded his health struggles. During the Covid pandemic, I monitored his oxygen saturation levels at night with a pulse oximeter, and it was common for readings to fall into the low 80s. His breathing would pause intermittently, followed by gasping for air. A chest CT I insisted upon revealed some lung damage attributed to double pneumonia he had as a child, but he also battled chronic fatigue and a deep-seated distrust of medical advice, which I once found frustrating. In hindsight, I realize his symptoms were often dismissed as mere consequences of weight or gas. Shortly before his demise, he began taking metformin, which also caused bloating and diarrhea for me; I suspect it may have exacerbated an already fragile condition of his gut or immune system. Notably, he experienced central chest discomfort for two days preceding his collapse. I’m not a medical expert, but I can’t shake the thought that he might have had an undiagnosed autoimmune disorder affecting his gastrointestinal system, possibly paired with a systemic allergic response. I suspect his sensitivity to mites could have played a role, potentially leading to complications like a pulmonary embolism or aortic dissection, or triggering an autoimmune inflammatory reaction that precipitated the cardiac incident. The lack of positive response to resuscitation efforts and the nature of his central pain have led me to question whether the heart attack was the initial issue or a secondary outcome. I am eager to uncover the true nature of my father’s health crisis. If anyone has encountered similar situations or can offer insights, I would greatly appreciate it. Furthermore, I am interested in discovering better approaches to interpret and manage complex chronic symptoms like those he experienced, as I believe his case is not an isolated one.
