Barium Sulfate Oral Contrast Concerns
I am scheduled for a CT scan tomorrow that was initially prescribed without any contrast material. However, during the appointment scheduling, I was informed that I must collect a barium sulfate drink today to consume prior to the scan. They issued me two bottles each containing 450 ml; one is to be consumed two hours before the scan, which is set for 1:20 PM EST, and the other one hour beforehand. As someone who takes Metoprolol for high blood pressure, I am wondering if it is safe to drink the barium in conjunction with my medication. Additionally, I have read reports of individuals experiencing elevated heart rates and chest pain as possible side effects. How prevalent are these symptoms, particularly among those who already have a history of high heart rates and chest discomfort? I am a 27-year-old woman. Thank you!

It's understandable to feel concerns about consuming barium sulfate for a CT scan, particularly in relation to your medication and any potential side effects. Here’s a breakdown of your issues and actionable steps to consider.
Main Points:
- Barium Sulfate and Metoprolol: Generally considered safe to take both.
- Potential Side Effects: While some patients report elevated heart rates and chest discomfort, these are not very common.
- Monitoring Symptoms: Keep an eye on how you feel before and after consuming the barium.
Explanation:
Barium sulfate is a contrast agent used in imaging studies, including CT scans, to help improve the visibility of your gastrointestinal tract. It's usually safe to take along with medications like Metoprolol, which is prescribed for high blood pressure. Metoprolol works by slowing down your heart rate, potentially counteracting any temporary increase in heart rate that might occur due to anxiety or other factors during this process.
Although a few reports mention elevated heart rates and chest pain after taking barium sulfate, such side effects are uncommon. Most patients tolerate it well without significant issues. Since you have a history of heart rate variations, it’s wise to be cautious.
Next Steps:
-
Talk to Your Healthcare Provider: If you haven’t already, consider discussing your concerns with the provider who recommended the CT scan. They can confirm that it’s safe for you to proceed with the barium sulfate.
-
Monitor Your Condition:
- When you take the barium, pay attention to how you feel. If you notice any significant changes such as chest pain, extreme discomfort, or persistent rapid heart rate, contact a healthcare professional immediately.
- Try to stay calm and relaxed, as anxiety can also affect your heart rate.
-
Stay Hydrated: Drink plenty of water before and after consuming the barium to help clear it from your system afterward.
-
Follow Instructions Carefully: Make sure to adhere to the timing indicated for consuming each bottle of barium to ensure optimal results for your scan.
If you feel overly concerned or experience any unusual symptoms at any point, don't hesitate to reach out to your healthcare provider for advice. You’re taking a positive step toward your health by preparing for the scan!

Cortisol Levels and Symptoms: Seeking Clarity
Hello everyone. I'm a 35-year-old Caucasian male weighing 250 pounds. During my recent annual health examination, a unique lab test was performed that we usually don’t conduct: a cortisol test. My doctor suggested it due to certain symptoms I've been experiencing. The blood sample was taken at approximately 10:15 AM, and the results indicated a cortisol level of 4.3. However, according to the patient portal, this reading falls below the normal range. I’m curious if this low level could shed some light on the various issues I've been facing. For instance, I've been struggling with temperature regulation; I sometimes feel overheated even when the room is cold, while at other times I feel chilled in reasonably warm conditions. Additionally, I often break into sweat unexpectedly. I'm also dealing with persistent nausea and an overall sense of fatigue. Should I be concerned about these findings? I reached out to my primary care physician through the patient portal since I'm feeling a bit uneasy about this situation. Prescription Medications: - Advair (500/50 twice daily, although I've been inconsistent with taking it) - Suboxone (4 mg strip once daily) - Duloxetine (20 mg once daily) - Lisinopril (5 mg once daily) - Pantoprazole (20 mg once daily)
Ongoing Concerns with Elevated Immature Granulocytes
Age: 60 years, Height: 5'10", Weight: 169 lbs, Ethnicity: Caucasian. Issue: For several years, my Complete Blood Count (CBC) has consistently shown elevated Immature Granulocytes. I am a professor of physics at a prominent university in the United States. My medical history includes Type 2 Diabetes (which is well-managed), high cholesterol levels (hypercholesterolemia), panic disorder, seborrheic dermatitis, and mild cognitive impairment. Current Medications: Metformin, Rosuvastatin, Klonopin, Vascepa, Vitamin D3, Nizoral shampoo. Over the past three years, I have been experiencing significant fatigue and breathing difficulties. These symptoms tend to fluctuate, with days of severity followed by some relief. Writing this message is a challenge for me at the moment. Classes are about to resume, and I am uncertain if I will be able to keep up this time. I visited the emergency room on August 16, 2025, and was diagnosed with Diverticulitis, for which I am currently taking Augmentin for ten days. Upon reviewing my bloodwork history, the persistent presence of elevated Immature Granulocytes is a concerning factor. Whenever I discuss this with my primary care physician, she seems dismissive. I often feel that my physical symptoms are misattributed to psychological issues. The latest data point from my IG% levels was recorded during my recent ER visit on August 16, 2025.
Could It Be a Decidual Cast or Something Else?
Yesterday, while out shopping with my husband, I mentioned that I needed to visit the restroom. Once there, after taking care of necessary business, I noticed something upon wiping that caught my attention. Here are a few observations I'd like to share: - I experienced no cramping at all. - My menstrual cycles usually arrive after the 25th of each month, although I realize they can come earlier; I felt it was worth mentioning. - I'm currently using a copper IUD for contraception. - I felt completely at ease with what I passed. - Throughout the past week, I have taken several pregnancy tests; some indicated a faint positive line, while others were negative, leaving me uncertain. - As of today, I have not experienced any bleeding, heavy periods, or cramping—nothing at all. I haven’t visited a healthcare professional due to a lack of insurance, but I’m open to seeking one out. Could this possibly be a decidual cast, or does shedding only occur during menstruation? Alternatively, might I be mistaken about what happened? Any insights would be appreciated!
Should I Perform Regular Breast Checks?
Hello, I’m a 19-year-old, and during my recent physical examination, my doctor performed a breast check, a procedure she has carried out for the last two or three years. However, she has never mentioned that I should be doing self-examinations. I am keen on maintaining my health, so I did some research and found that many sources suggest that regular breast self-exams are not necessary until the age of 25. I’m unsure if I should begin self-checking now, or if I might need to find a new doctor who adheres more closely to established guidelines. My reason for raising this concern stems from my health anxiety. If self-examinations aren’t essential at this age, it would certainly help alleviate my worries. Nevertheless, I am puzzled as to why my doctor checks my breasts if there’s no immediate need for me to be doing so myself.
