Concerns Regarding Enlarged Right Ventricle
Age: 33 years | Gender: Male Height: 5 feet 7 inches (170 cm) Weight: Currently 320 lbs, reduced from 343 lbs on May 5, 2025 Medical Background: History of obesity, non-alcoholic fatty liver disease, mild asthma, past left ventricular hypertrophy (LVH) Current Medications: Metoprolol tartrate 25 mg thrice daily, Ivabradine (Corlanor) 5 mg twice daily, Atorvastatin 20 mg, Levothyroxine 150 mcg, Vitamin D 4000 IU, Pepcid 40 mg, Zyrtec 10 mg, Melatonin 2.5 mg, Albuterol inhaler as needed. **Symptom Timeline & Echocardiographic Results** **May 5, 2025** — Commenced a calorie-restricted diet ranging from 1500 to 1700 calories per day; weight at this point: 343 lbs. **May 14, 2025** — Experienced sudden, intense palpitations located in the lower throat, particularly while lying down. Accompanied by sensations of chest pressure and breathlessness, these occurrences happened nightly and lasted between 2 to 4 hours, with two occasions extending for 7 hours. Heart rate consistently ranged between 50 to 67 beats per minute. **May 14–29, 2025** — Total of eight visits to the emergency room: - EKG results: Normal - Troponin levels: 0.05 ng/mL during a severe incident - BNP levels: 16 pg/mL - CT Angiogram: Revealed normal coronary and pulmonary arteries - Liver dimensions: 24 cm; spleen size: 14 cm, consistent with known NAFLD **from May 29, 2025** — Following a prescription for lorazepam (1 mg daily), episodes became less severe, generally lasting about 15 to 30 minutes, occasionally up to 1 hour. Maintaining an elevated sleep position was necessary as lying flat triggered symptoms. Daily occurrences of pulsation sensations in the throat and intermittent shortness of breath persisted. **June 19, 2025** — Results from echocardiogram: - Right Ventricle (RV): 5.2 cm (notably enlarged) - Left Ventricle (LV): Normal size, significantly smaller than RV - RV Function: Preserved - Pulmonary Artery Pressure: Approx. 30 to 32 mmHg - Tricuspid Regurgitation: Mild - BNP: Still within normal range; weight now at 320 lbs - Previous echocardiogram in 2023 (at roughly 359 lbs): - RV size: 2.85 cm - LVH was observed (which is no longer present in the 2025 echocardiogram) **Concerns** - Rapid progression of RV enlargement, which increased by approximately 2.35 cm over the last two years. - Current size of RV exceeding that of LV. - Awaiting results from the Zio patch (due June 24–25). - Sleep study planned for August 5, 2025; CPAP expected to be initiated mid to late September. - Continued sodium intake remaining around 4000-5000 mg daily while adhering to the calorie restriction. - Currently leading a sedentary lifestyle due to back pain, accumulating fewer than 100 steps daily, yet weight loss is ongoing. **Questions for Cardiologists/Healthcare Providers** 1. Is the observed rate of RV expansion alarming, possibly indicating early pulmonary hypertension or another structural issue? 2. Can factors like obesity and untreated sleep apnea solely lead to this rate and type of enlargement? 3. Should further imaging, such as MRI or right heart catheterization, be considered in the near future? 4. Is there a concern about the size discrepancy between the RV and LV, despite normal function and BNP readings? 5. Could it be possible to reverse or stabilize this condition prior to beginning CPAP therapy in September? 6. What strategies can I adopt to manage my anxiety regarding potential RV failure or heart collapse? 7. Will my RV continue to enlarge, or is there a possibility for stabilization or even reversal? Any insights or advice would be greatly appreciated. Thank you for your attention.

It's understandable to have significant concerns regarding the enlargement of your right ventricle (RV), especially given your medical history and symptoms. I'll address your questions while providing clarity about your situation and outlining actionable steps.
Key Points:
- The rapid enlargement of your RV is concerning and may indicate underlying issues, such as pulmonary hypertension.
- Factors like obesity and untreated sleep apnea are indeed related to RV enlargement.
- Lifestyle changes and managing your current conditions may help stabilize your heart health prior to starting CPAP therapy.
Explanation:
-
RV Enlargement: An RV measurement of 5.2 cm is notably enlarged, especially when compared to your left ventricle (LV). While preserved function and normal BNP levels are positive signs, the rapid growth can indicate stress on the heart, possibly linked to pulmonary hypertension or structural heart issues.
-
Contributing Factors: Obesity and untreated sleep apnea are significant contributors to RV changes. The excess weight increases cardiac workload, and untreated sleep apnea can lead to changes in heart structure, including RV enlargement.
-
Further Imaging: Depending on how your symptoms progress, additional imaging like an MRI or right heart catheterization may be warranted for better evaluation. This should be guided by your healthcare team.
-
Size Discrepancy: While the size difference between your RV and LV is concerning, the fact that your LV shows normal function and size is reassuring. However, ongoing monitoring is essential.
-
Reversal/Stabilization: Losing weight and addressing sleep apnea with CPAP therapy may help improve RV size and function over time. Consistent weight management can be crucial.
-
Anxiety Management: Managing anxiety is important. Techniques such as mindfulness, breathing exercises, and talking to a therapist can be beneficial. Keeping a symptom diary may help track how your anxiety correlates with physical symptoms, allowing you to address them more effectively.
-
Future of RV Size: Whether your RV will continue to enlarge or stabilize will depend on lifestyle changes, medical management, and the effectiveness of upcoming treatments like CPAP. Regular follow-up with your cardiologist is crucial.
Next Steps:
-
Dietary Modifications: Aim to reduce your sodium intake significantly from the current level (4000-5000 mg daily). Consider consulting a nutritionist specialized in cardiac health for personalized dietary advice that aligns with your calorie goals.
-
Increase Physical Activity: Engage in gradual physical activity tailored to your comfort level. Even short, gentle walks or exercises tailored for individuals with back pain can be beneficial. Small, consistent movements can help improve heart health over time.
-
Monitor Symptoms and Weight: Keep track of any changes in your symptoms, including palpitations and breathlessness, along with your weight loss progress. Note what triggers your symptoms, especially in relation to dietary intake and physical activity.
-
Upcoming Medical Appointments: Prepare your questions for the cardiologist and discuss any concerns about further imaging or treatment options to ensure you receive a comprehensive plan moving forward.
-
Mental Health: Consider seeking support for anxiety, either through a professional or support groups, focusing on heart conditions and lifestyle changes.
Please take these concerns seriously while also being proactive in seeking positive lifestyle changes. Your dedication to your health is essential, and every small step counts. Feel free to reach out for further clarification or support.

Concerns About Rectal Discomfort
Hello everyone, I’m 48 years old, weigh 180 pounds, don’t smoke, and I stay active with occasional alcohol consumption. Recently, I’ve been experiencing several troubling symptoms over the past week: - I’ve felt brief episodes of pain in my anal region, specifically a couple of inches inside. This discomfort has occurred about three to four times but hasn’t reappeared in the last few days. - My bowel habits have remained relatively consistent, although I did visit the bathroom three times within an hour yesterday due to anxiety, just to confirm everything was normal. - I noticed a small amount of bright red blood on the toilet paper during one instance, about the size of a square inch, but haven’t seen any since then. - Currently, I have a mild feeling of pressure in my rectal area, but no pain is present. I suspect this might be related to the straining I did during yesterday’s bowel movements. - Additionally, I’ve felt occasional twinges in my pelvic area. I spent the last three weeks on a firmer mattress while house-sitting, which could also be contributing to this discomfort. - My appetite remains unchanged. As I mentioned, I rarely drink alcohol and I consume very little sugar. I have an appointment scheduled with my general practitioner on July 9 for a rectal examination. Given that my father passed away from bowel cancer at the age of 68, I realize I might be overdue for a check-up by a couple of years. I understand that definitive diagnoses cannot be provided online, but based on the symptoms I’ve described, how concerned should I be about my situation?
12 Days Without a Period and Negative Pregnancy Tests – Seeking Guidance
I'm reaching out for assistance. As a minor, standing at 5'5" and weighing 145 lbs, I'm feeling overwhelmed and in need of some advice. I often rely on Plan B, using it around two to four times each month. I understand this isn’t the healthiest choice, but I am very anxious about the possibility of becoming pregnant, especially since my parents oppose birth control. On May 23, I had unprotected intercourse right after my period ended, and my partner did not ejaculate inside me. I took Plan B about five hours later and experienced some bleeding two days afterward, which resembled my usual period and lasted for about three days. Now it's June 23, and I find myself 12 days past the expected start of my period. I've taken five pregnancy tests to date, the latest being on June 21, and all results have come back negative. Typically, my menstrual cycle is regular, making this delay concerning. For the past three days, I have also been experiencing mild cramps, which feel similar to the onset of my period, yet it still hasn't arrived. I've read that pregnancy tests are generally conclusive after three weeks, yet I’ve also encountered stories of false negatives. Could there still be a possibility that I might be pregnant? I feel foolish for my predicament, and I would greatly appreciate any guidance or advice. Thank you very much for your support.
More than Six Months of Progressive Abdominal Discomfort
A 32-year-old male, with a medical history primarily of asthma (which does not require ongoing treatment), initially visited his general practitioner in December 2024 due to mild discomfort in the right lower quadrant of his abdomen. Following this visit, a CT scan was conducted, revealing slight enlargement of the mesenteric lymph nodes. Since that time, he has experienced a gradual escalation in abdominal pain, yet there have been no notable alterations in his bowel movements. He has lost approximately 3 kilograms over the past six months, although his weight has stabilized over the last two months. He underwent gastroscopy and colonoscopy, both of which returned normal results. A consultation with a hematologist also ruled out small bowel lymphoma as a potential cause. The most recent CT scan, conducted in March 2025, showed diffuse thickening in a loop of the distal jejunum alongside mildly enlarged mesenteric lymph nodes, with no significant change in size compared to prior scans. Both his gastroenterologist and the surgeon who performed the scopes believe that these findings may be attributed to peristalsis. His gastroenterologist subsequently diagnosed him with a functional gut disorder. He is scheduled for a repeat CT this week to assess whether these changes are persistent. He has experienced some relief from his abdominal pain after beginning treatment with Nortriptyline at a dose of 25 mg about a month ago. However, the discomfort has intensified over the past week, prompting an increase in his dosage to 50 mg. Currently, he is uncertain about future steps or additional tests he should pursue and would appreciate any guidance available!
Forgotten Medrol During Travel - Inquiry About Tapering
I’m a 24-year-old male, standing at 5'6" and weighing 170 pounds. I don't smoke, and my only current medication is Medrol, which I take for a rash affecting my hands and feet. I’m posting here since my doctor and pharmacist are unavailable right now, but I will reach out to them in the morning. I was prescribed 4mg Medrol tablets to be taken over a period of 6 days to address some unusual blistering on my hands and feet. Yesterday was Day 1, and I took a total of 6 tablets (24mg) in the evening, as directed. Today, on Day 2, I managed to take 1 tablet with breakfast and another with lunch. However, after that, I boarded a flight and realized I left the rest of my pills at home. I was supposed to take 3 additional tablets today—2 at lunchtime and 1 before bed—and then reduce the dosage over the following 4 days. Unfortunately, I won’t be able to take any doses for about 48 hours because I’m traveling until Wednesday evening. My main concern is whether missing this taper schedule could lead to immediate issues. The medication has significantly alleviated my blistering symptoms so far; how likely is it that those symptoms will return strongly due to this gap in treatment? Any advice would be appreciated, as it would help me to relax better tonight, and I’ll make sure to resolve this with my healthcare team tomorrow. Thank you!
Identifying a Mysterious Bite on My Fiancé
My fiancé is a 29-year-old man, approximately 5'5" tall and weighing around 250 pounds. He is currently taking Metformin and Lisinopril; he doesn’t smoke. The Metformin is indicated for managing prediabetes, which typically involves high blood sugar levels, while Lisinopril is likely prescribed for hypertension. The bite in question is located on his calf, and he suspects it began to develop last Thursday, but only brought it up to me today, Monday. Although I wanted to include an image for clarity, it seems I’m unable to due to community restrictions on attachments. Therefore, I’ll provide a detailed description to the best of my ability in hopes of receiving useful feedback. On his calf, there’s a suspicious mark that resembles a bug bite. At the center, there’s a small blister, surrounded by a circular rash. It could possibly resemble a bullseye pattern, but I find it challenging to accurately compare it to online images. I’m leaning towards the possibility of it being a spider or tick bite, with increasing concern over Lyme disease. Recently, we both lost our jobs and relocated to a different state, initiating new jobs in the process, so we currently lack health insurance. I am uncertain whether this situation requires urgent medical attention, what home remedies might help, and to what extent we should be concerned about it—especially since a few days have passed since its appearance.
