Consequences of Long-Term Levothyroxine Withdrawal
Greetings. To start, I want to express that I understand the importance of this situation, but I’m currently facing some challenges and lack health coverage. Recently, I secured a new job and relocated to a new apartment, with my insurance set to begin shortly. At 22 years old, weighing around 150 pounds and standing 5'7", I've been living with Graves’ disease, which I underwent treatment for with radioactive iodine approximately seven years ago. As a result, I possess minimal to no functional thyroid tissue. My prescribed dosage of levothyroxine was adjusted from 112 mcg to 150 mcg about eight months prior. Unfortunately, I lost my father six months ago, and I was covered under his health plan throughout my college years, which I obviously lost after his passing. Now, after finally landing a good job and obtaining my own living space, I'm in the process of finding a primary care physician. I have gone without my levothyroxine for the past three months. Surprisingly, I don’t notice any substantial changes in my wellbeing; my weight remains stable (if anything, I might have lost a little), and I’m not experiencing cold intolerance, hair loss, fatigue, mood changes, digestive issues, irregular menstrual cycles, or any other typical symptoms. In previous instances when I missed doses and visited my endocrinologist, my thyroid-stimulating hormone (TSH) levels were significantly elevated, indicating that my current state might be worse. However, I feel generally normal, which raises concerns about the seriousness of my situation. Naturally, I turned to online resources, which alarmingly suggested that I could face a myxedema coma. Yet, I wonder if this is a pressing concern now or something that occurs after extended periods without medication. Therefore, my inquiry is: how might this absence of medication impact my health, and how concerned should I truly be? I appreciate your willingness to read through this. Thank you!

Thank you for sharing your situation and concerns regarding your levothyroxine treatment. It's understandable to feel anxious about your health, especially after experiencing significant life changes. While you may not be noticing obvious symptoms, it's important to recognize the potential consequences of long-term withdrawal from levothyroxine, particularly given your history with Graves' disease and minimal thyroid function.
Main Points:
- Importance of Levothyroxine: Without adequate thyroid hormone, your body may eventually be at risk for hypothyroid complications, but symptoms can vary widely from person to person.
- Potential Risks: Long-term withdrawal can lead to serious health issues, including heart problems, cholesterol elevation, and in extreme cases, myxedema coma.
- Monitoring Your Health: Since you have experienced no current symptoms, it’s still essential to get your hormone levels checked soon.
Explanation:
Levothyroxine is a synthetic thyroid hormone that your body needs to function properly, especially since you have little to no functional thyroid tissue left. Lack of this hormone can lead to elevated TSH levels, which your past experiences have shown are elevated when medication is stalled. Common symptoms of hypothyroidism can sometimes be subtle and develop gradually, which can lead individuals to underestimate the seriousness of their condition.
Myxedema coma, though rare, can occur when hypothyroidism is left untreated for an extended period but is more common in scenarios of extreme neglect or after severe illness. Given your previous history and the length of time without medication, it’s wise to pay attention to this.
Next Steps:
-
Seek Medical Attention Promptly: As soon as your health insurance kicks in, prioritize booking an appointment with a primary care physician or an endocrinologist. Inform them of your history and current situation regarding levothyroxine. They will likely want to run lab tests to evaluate your TSH and overall thyroid function.
-
Monitor Symptoms: Until you can see a doctor, keep a close watch on your health. Pay attention to any new symptoms that may arise, such as fatigue, cold intolerance, weight gain, or changes in mood. While feeling well is great, staying vigilant is important.
-
Consider Temporary Solutions: If you find you cannot see a physician right away, explore community health centers or resources that may offer access to medications on a sliding scale or through patient assistance programs. This could provide you with temporary support until your insurance is effective.
-
Educate Yourself: Continue to research reputable resources regarding thyroid health. The more informed you are, the better you can advocate for yourself when you do consult with a healthcare provider.
Your health is paramount, and taking proactive steps now will help ensure your well-being as you transition into your new job and living situation. Please don’t hesitate to reach out if you have more questions or need further support.

Seeking Insight from Neurosurgeons and Plastic Surgeons Regarding Forehead and Eye Concerns After Craniotomy
Greetings to all healthcare professionals and community members, I am in search of insights from seasoned neurosurgeons and plastic surgeons across the globe. As a 21-year-old male, I underwent a craniotomy 1.5 years ago to remove a minor blood clot caused by a bicycle accident. My recovery was uncomplicated and went well until I observed some notable changes: a notable dent in my forehead and a sunken appearance of my left eye, known as enophthalmos. Initially, I disregarded these changes, but I recently decided to seek a surgeon's opinion regarding cosmetic reconstruction. A CT scan showed pre-existing fractures in my frontal sinus and orbit, which my neurosurgeon warned could potentially allow air to enter the brain, posing a risk of future infection. Throughout the years since my surgery, I experienced no functional issues, which is why my concern initially stemmed from aesthetic reasons. However, my anxiety has grown, especially since the exact locations of the fractures are unclear to me. The surgeon mentioned these fractures pertained to the frontal sinus and orbital area, and there was uncertainty about reopening the bone flap. Feeling unsure about the doctor’s expertise, I am now seeking honest second opinions: - Are these fractures genuinely in need of intervention from a safety perspective? - What would be the optimal procedure for correcting the aesthetics of my forehead and orbit? - Is there an option for minimally invasive surgery or advanced surgical planning with 3D imaging available? I am more than willing to provide additional details or connect personally with anyone who can assist. I am also prepared to share my CT scans or a zip file containing 3D imagery for those interested in reviewing my case. Your guidance would be invaluable in helping me navigate this situation. Thank you!
Persistent Dizziness Despite Epley Maneuver Attempts
I am currently 31 weeks pregnant, weigh 226 pounds, and stand at 5’7". I have been diagnosed with gestational diabetes and hypothyroidism, along with having environmental allergies. On Tuesday evening, I slipped in the shower and injured my right knee. By Friday morning, I awoke feeling somewhat lightheaded but did not prioritize it, choosing instead to carry on with my routine. However, during my midday appointment with a physical therapist, I experienced significant dizziness when I was turned onto my right side. Ultimately, the therapist concluded the session prematurely and departed. I returned home, where I continued to feel quite unwell and decided to take a nap. I reached out to my obstetrician, who informed me that my symptoms were likely not related to my pregnancy, suggesting I could follow up on Monday if my condition didn’t improve. Later that evening, I sought help at an urgent care facility, where they conducted a urine culture and an EKG, both yielding normal results. Neurological tests were also satisfactory, revealing my blood pressure to be 105/76, pulse at 99, and oxygen saturation at 99%. My blood sugar levels were average, recording a standard 95 over the last three days. The medical staff diagnosed me with Benign Paroxysmal Positional Vertigo (BPPV) and advised me to watch a tutorial on the Epley maneuver on YouTube to try at home. Last night, my husband, who is not a medical professional, attempted the Epley maneuver twice, focusing on the right side since that was the source of my dizziness. We allowed a gap of 1-2 hours between attempts to see if there would be any effect. While I noted that looking to the right didn’t induce dizziness, I still felt some unsteadiness when shifting from lying on my left side to my right. Unfortunately, I experienced vomiting at midnight and again at 10 AM. Thankfully, I am not suffering from Hyperemesis Gravidarum (HG), as I have been ill fewer than ten times throughout my entire pregnancy. Currently, I feel a general sense of dizziness, but it is not as intense or direction-specific as it was yesterday. My main concerns are that I am too unwell to drive, fulfill work obligations, or care for my other children. I lack the energy even to do household tasks like laundry, bathing, or preparing food. Should I assume all these symptoms are linked to vertigo, or might there be an underlying issue that requires attention?
Concerns Regarding Self-Massage Techniques on the Neck
Demographic Background: South Asian, Age: 34, Weight: 55 kg I recently engaged in a self-massage of the front neck area, which I now realize may have been risky. To describe it accurately, it was akin to attempting to strangle oneself with a single hand while applying considerable pressure along the neck. I utilized my thumb on one side and my fingers on the opposite side, starting from the pulse point. Surprisingly, I did not experience pain nor did the pressure feel sufficient to cause choking, but for about two hours, I sensed a pushing sensation around my neck. Although there was discomfort, it wasn't painful. Now, I'm anxious about the possibility of having harmed an artery or vein during this. Additionally, I've noticed a burning feeling in my neck while trying to sleep. Given that I also have OCD, I've found myself repeatedly massaging my neck with the same intensity as before. I’m seeking guidance—could I have inadvertently injured my artery?
Strange Symptoms: Numbness, Body Twitches, and Unexplained Forehead Lump
A 31-year-old woman diagnosed with Hashimoto's disease and hypothyroidism is experiencing an unusual set of symptoms. **Current Medications:** - Tirosint 75 mcg three times a week - Topamax 100 mg daily - Nurtec as needed - Minoxidil 2.5 mg daily On Monday evening, a noticeable bump appeared on her forehead; it was unexpected since there had been no prior indication of it. Initially thinking it might be a bug bite that would resolve on its own, she soon realized it remained consistent. The bump is subtle but palpable when she touches it. Later that night, she began to feel discomfort in her left leg, which she suspected might be sciatica. However, the sensation evolved into a severe burning and tingling sensation, leading to profound numbness in her leg, hip, and foot, and, subsequently, in her left arm and hand. After attempting to alleviate discomfort by placing a pillow between her knees, she went to sleep. By the next day, the numbness persisted, extending to her neck and face, with the troubling nature being that it fluctuates between areas without relief. Eventually, similar sensations started in her right side affecting her arm, hand, hip, foot, and leg. Concerned, she contacted her primary care physician's office for a same-day appointment regarding her numbness. During the commute, she noticed her right hand twitching noticeably, akin to a heartbeat visible above her thumb, involving all fingers. Shortly afterward, her left hand also began slight twitching but to a lesser degree. At her appointment, she showcased her twitching hand to the doctor. Given her history of migraines, the ongoing headaches were mentioned, but since she frequently experiences migraines, it was considered an existing issue rather than related to her current symptoms. Notably, the hand twitching persisted throughout the day, starting around 2 PM and continuing unabated into the night around 9 or 10 PM. A blood test was conducted, and she was informed that arrangements for a brain MRI would be made for the following day. However, upon attempting to schedule the MRI, she was told there would be a two-week wait. Despite her doctor’s attempts to expedite the process, a stat order could not be approved. Although the option of visiting the emergency room was suggested, it was unclear if an MRI would be granted there. As of Friday, results from the earlier blood work had yet to arrive. Additionally, she began experiencing involuntary body jerks, including sudden movements of her arms and legs. She proceeded to the ER, where the necessity for an MRI was acknowledged, but the hospital confirmed they were unable to perform one through the emergency department. Instead, they conducted blood tests and a CT scan of the head, yielding no conclusive results, and she was discharged. That night, she experienced multiple tremors throughout her body. Upon examining her reflexes, the PCP noted signs of hyperreflexia, adding another layer of concern. Despite numerous tests and consultations, no concrete explanations have been provided regarding her condition, leaving her feeling uncertain. The PCP’s only response was a lack of knowledge, while a hospital doctor mentioned the possibility of electrolyte imbalances, though her blood work appeared normal. This absence of clarity regarding her symptoms is particularly stress-inducing, and she fears waiting weeks for an MRI might delay identifying the issue. With an existing autoimmune disorder, she worries about the possibility of conditions such as MS, prompting her to seek alternative recommendations rather than enduring prolonged uncertainty.
Conflicting Medical Opinions on Orthopedic Surgery for Elderly Patient
Hello, I’d like to gain insights from healthcare professionals regarding a situation concerning my father. Recently, my 77-year-old dad suffered a clavicle fracture near his left shoulder while visiting his hometown. Initially, he received treatment from a local physician who placed a bandage and sling on his injury and advised against surgery due to his advanced age. After returning home, he opted to consult with an orthopedic specialist, and I accompanied him for that visit. This new physician suggested surgical intervention involving the insertion of a plate and screws to facilitate the healing of the fracture. Unfortunately, the estimated cost for this procedure exceeded our financial capabilities, leading my father to revert to the first doctor’s recommendation of avoiding surgery. The orthopedic surgeon noted that without surgical intervention, my dad's chances of proper recovery were about 50/50, warning that he might lose the ability to raise his arms fully. I am curious as to why there were such stark differences in the doctors’ recommendations regarding my father’s treatment. What are the potential complications of surgery for someone in his age group? Ultimately, what would be the most advisable approach to take in his situation? I appreciate any guidance you can offer. Thank you.
