Seeking Insight: Is My Doctor Overlooking My Low T3 for Anemia Diagnosis?
Greetings! I’m a 19-year-old female, and I find myself somewhat bewildered by my latest lab findings and the guidance I've received from my doctor. I visited a dermatologist due to significant hair loss that I’ve been suffering from for over the past year. Furthermore, I’ve been battling a myriad of distressing symptoms for several years, including persistent tiredness that doesn’t improve with 8 to 10 hours of sleep, an inability to withstand cold temperatures, struggles with weight loss, and a severe skin condition that leads me to itch my legs so badly that I create sores and scars. Until now, I tried to overlook these issues, but the severity of my hair loss prompted me to seek professional help. The dermatologist's blood tests revealed some concerning indicators: a notably high inflammation marker, HS CRP, at 12.3 mg/L, alongside low thyroid hormone levels, with Free T3 measured at 2.9 pg/mL and Total T3 at 74 ng/dL. I had just completed a cold when I underwent the blood work—about a week after it began—so my dermatologist believed the elevated CRP could be a result of that recent illness. While she expressed concern regarding my thyroid levels and wanted to refer me to my Primary Care Physician (PCP) before suggesting any treatment, my PCP took a different stance entirely. He disregarded the thyroid concerns, citing that my TSH levels were normal at 1.04 mIU/L. Instead, he focused on what he described as "essentially anemia," pointing to past tests and claiming that my current elevated ferritin level of 127 ng/mL was misleadingly high due to the inflammation caused by my recent illness. This conflicting diagnosis is perplexing. While my PCP insisted that I might be iron deficient, my dermatologist had previously assured me that my iron levels were adequate. I found myself questioning the rationale behind my PCP’s dismissal of the low T3 levels and my other symptoms in favor of an iron deficiency narrative, especially since my ferritin is elevated. Ultimately, he opted to conduct another blood test solely for iron without including any thyroid checks, suggesting that he didn’t wish to invest time in exploring that aspect. The differing opinions from my dermatologist and PCP have left me confused about the right direction to take.

Your situation involves several interconnected health concerns, including possible thyroid issues, fatigue, hair loss, and anemia. It's understandable to feel confused with differing opinions from your healthcare providers. Let’s clarify the main points and provide actionable steps for you.
Main Points:
- Thyroid Function: Your low Free T3 levels and high inflammation marker (HS CRP) are concerning, especially in the context of your symptoms.
- Anemia: Your PCP is focusing on potential iron deficiency but acknowledges that your ferritin levels are elevated, complicating that diagnosis.
- Need for Clarity: The conflicting opinions suggest a need for a more comprehensive evaluation to address both your thyroid and anemia concerns.
Explanation:
- Thyroid Hormones: Free T3 is an important thyroid hormone that helps regulate metabolism. Low levels can lead to symptoms like fatigue, weight changes, and even hair loss. Normal TSH levels don’t always capture all thyroid issues since they don’t reflect the active hormones (like T3) directly.
- Anemia: Ferritin indicates iron stores, but elevated ferritin can sometimes occur due to inflammation, making it less reliable for assessing iron deficiency. Your symptoms of fatigue and pallor could also suggest iron-deficiency anemia despite elevated ferritin levels.
Next Steps:
-
Request Comprehensive Thyroid Testing: Ask your healthcare provider for a full thyroid panel that includes Free T3, Free T4, and TSH to comprehensively evaluate your thyroid function, even if your PCP has previously dismissed it.
-
Follow Up on Anemia Testing: Since your PCP mentioned conducting additional iron tests, make sure the testing includes serum iron, total iron-binding capacity (TIBC), and transferrin saturation to get a complete picture of your iron status.
-
Track Symptoms: Keep a daily log of your symptoms (fatigue, skin issues, hair loss) and any potential correlations with dietary intake or menstrual cycles. This can provide valuable insights for future discussions with your healthcare team.
-
Seek a Collaborative Approach: If the conflicting advice continues, consider seeking a second opinion from an endocrinologist who specializes in thyroid and hormonal issues. This can help you weigh the insights from both your dermatologist and PCP.
-
Consider Nutritional Support: While awaiting further testing, ensure you are eating a well-balanced diet rich in micronutrients, including iodine (found in fish, dairy, and iodized salt) and iron (present in lean meats, legumes, and leafy greens).
By addressing both your thyroid and potential anemia comprehensively, you can take an important step towards understanding and improving your health concerns. Please remember that it's essential to advocate for your health and seek clarity until you're satisfied with the explanation and the plan of action.

Seeking Clarity on Brain MRI Results
I’m a 36-year-old man experiencing occasional headaches, and I have no additional health concerns. I take Lexapro for anxiety and Ativan as needed. Earlier this week, I underwent a non-contrast MRI scan of my brain, and I have received the following report: **REASON FOR EXAMINATION:** Periodic headaches described as dull in nature. **COMPARISON:** None available. **TECHNIQUE USED:** The imaging included sagittal T1, axial FLAIR, axial T2-weighted, diffusion-weighted, and coronal gradient-echo sequences of the brain. **RESULTS:** The size of the ventricles and sulci appears to be normal. The position of the cerebellar tonsils is also within normal limits. Notably, a bilobed, septated lesion measuring 18 x 10 mm is located in the right parietal cortex, associated with some underlying edema or gliotic changes and cortical expansion. The pituitary gland size is normal. There are no signs of intracranial bleeding or any indications of recent infarcts in the cerebral regions, brainstem, or cerebellum. No abnormalities were detected on diffusion-weighted imaging. Additionally, there are no signal changes that would imply a demyelinating condition, such as multiple sclerosis. There are no fluid collections outside of the brain or subdural hematomas noted. Major blood vessels are patent, as indicated by the flow voids. The paranasal sinuses and mastoid air cells appear clear, although there is mild mucosal thickening in the left anterior ethmoidal air cells. **SUMMARY:** The findings suggest an 18 x 10 mm intra-axial cystic lesion in the right parietal lobe, accompanied by mild underlying edema or gliotic changes. This could possibly be an atypical manifestation of enlarged perivascular spaces or a benign cystic structure. Further evaluation with postcontrast imaging is advised. The overall conclusion of the MRI is otherwise normal. I’m feeling really anxious about these findings. Can anyone help me understand what this might mean?
Unexplained Bruising and Intense Itching
Hello, I’m a 20-year-old female, standing at 5 feet 2 inches and weighing 135 pounds. Recently, I have been experiencing intense itching that has resulted in significant bruising on my skin. Currently, I’m on several medications including spironolactone (which I haven’t taken for the last two weeks), Effexor, Aimovig, Wegovy, and Linzess. I do not use tobacco or consume alcohol. Apart from experiencing a generally sluggish digestive system, I have no pre-existing health issues. However, my family medical history indicates occurrences of Multiple Sclerosis, Hashimoto’s disease, diabetes, and eczema. The itching has become severe, leading to large bruises forming on my body. I consulted a virtual urgent care service, which advised me to visit the emergency room to check for potential blood clots or internal bleeding. Upon arriving at the ER, I underwent various tests, and I noticed that my resting heart rate has been notably elevated between 120 and 140 beats per minute, though I am uncertain if this is a new development. Eventually, I was discharged without any conclusive information, except with the advice to refrain from scratching. I have shared images of the tests conducted during my visit.
Understanding Prednisone Usage and Withdrawal
A 38-year-old woman, measuring 5’10 and weighing 125 pounds, with no smoking or drinking habits and a background of autoimmune disease, encountered a viral infection in December. In response to her condition, a specialist recommended a tapering regimen starting with a 40mg dose of prednisone for five days, followed by a gradual reduction through 30mg, 20mg, and 10mg over a total period of 20 days. After completing the course and halting the medication, she experienced severe symptoms approximately 36 hours later, including intense vomiting, debilitating headaches, and widespread pain throughout her body. Any physical contact provoked discomfort, leaving her in distress. Unable to reach her original provider, she consulted another physician who prescribed a lower dosage of 4mg of prednisone, instructing her to decrease the amount by 1mg every three days. Remarkably, she felt relief upon returning to the 4mg dose. However, she expressed concern regarding the potential effects when she ultimately weans off the medication entirely. She is seeking guidance on whether this method of tapering is typical and which specialist might be best suited to manage her prednisone treatment moving forward.
Navigating MALS Challenges: Seeking Guidance
Hello everyone! I’m a 36-year-old female dealing with multiple health conditions, including EDS (Ehlers-Danlos Syndrome), MALS (Median Arcuate Ligament Syndrome), and ulcerative colitis, among several other unrelated issues. I wanted to share my experience with MALS, which has been confirmed for me. Back in May 2024, I underwent revision surgery. Unfortunately, the recovery did not go as hoped. Due to my EDS, the celiac artery lacks the ability to function independently, which my surgeon described as it being "too floppy." At that time, I accepted this outcome because the excruciating pain had subsided, and I was able to eat and gain weight again. However, now I find myself facing a resurgence of pain that is quite intense. A CT scan I had last week revealed severe stenosis in my celiac artery, coupled with a soft tissue prominence at the diaphragmatic crus and the beginning of the celiac axis. Currently, I’m taking Norco 10-325 three times a day and Lyrica 75 mg three times daily. While these medications provide some relief, the pain is overwhelming, and I can’t help but feel as if I’ve returned to my previous struggles from two years ago. Doctors are suggesting that the only option is to go in and "clean out the adhesions". I come to you all for your insights: Do you think pursuing a clean out procedure is advisable, or could it pose too much risk considering my EDS? I appreciate your thoughts and thanks for reading my story.
Sore Throat and Tonsil Discomfort for Three Weeks
For the past two weeks, I have been experiencing significant pain in my tonsils. After consulting with urgent care, I underwent tests for both strep throat and mononucleosis, but the results were negative. The doctor advised me to be patient as the discomfort was expected to subside on its own. Unfortunately, my condition worsened, prompting me to return to urgent care three days later. During this visit, I was prescribed dexamethasone, a type of steroid, along with a ten-day course of amoxicillin. Remarkably, my symptoms began to diminish within hours. However, just three days later, I am starting to feel the throat and tonsil pain return. I am still on the amoxicillin regimen. What could be causing this resurgence of pain, and what steps should I take next?
