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.

Assessing My Health Concerns: How Anxious Should I Be?
I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.
Understanding Possible Seizure Triggers and Recurrence Risks
Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!
Understanding EEG Results for My 22-Month-Old Son: Insights Needed
Could someone help clarify this for me? My son, who is just 22 months old, hasn’t started walking yet, becomes tired easily, and has been experiencing behavioral outbursts. He had a febrile seizure in February 2025, followed by another unexplained seizure in April 2025, which led us to consult a neurologist. Since he was 3 months old, he has been receiving therapy from a physical therapist for torticollis. At birth, he spent five days in the NICU due to issues with meconium aspiration. A recent MRI showed normal results, and he also had a follow-up EEG after one conducted in July 2025. The results from this recent EEG were abnormal for a pediatric patient in awake, drowsy, and sleeping states. Notably, there were brief episodes of left frontotemporal delta slowing, which occurred mainly when he was awake and drowsy. There were no signs of epileptiform activity detected. In contrast, the EEG performed back on July 3, 2025, was deemed normal for both awake and drowsy states, again with no evidence of epileptiform irregularities, although it did not capture any sleep data. This examination was prompted by the child's existing history of febrile seizures. Importantly, he is not currently on any anti-seizure medications. The EEG procedure used standard electrode placements per the 10-20 system, conducted a single-lead EKG, and included continuous video monitoring. During the analysis, the background activity was symmetric, indicating some anterior-posterior (AP) organization, with a dominant rhythm of 50-80 microvolts at 7 Hz. His drowsy state was marked by a reduced amount of eye blink activity, less breathing motion interference, and a generalized slowing in theta/delta frequencies. Stage II sleep exhibited spindles and vertex waves patterns. Additionally, there were intermittent bursts of 250-300 microvolts in the left frontotemporal region with semi-rhythmic activity of 2-4 Hz, mostly observed during wakefulness and drowsiness. No definitive epileptiform discharge was noted. Photic stimulation during the test did not elicit a strong response, and hyperventilation was not conducted during this session.
INTENSE Spine Discomfort, Breathing Difficulties, Muscle Twitches, and Sweating
To elaborate on the situation mentioned in the title, I’ve been experiencing unusual muscle twitches and spasms for the past few days, along with some discomfort in my back. However, today, I felt an unexpected sharp pain shoot through my spine, which has left my legs feeling numb and made it impossible for me to sit up straight. Additionally, I’ve been dealing with cold sweats for the last hour and struggling to breathe properly. Perhaps I’m just overanalyzing things and it’s a common occurrence, but the intensity of the pain is overwhelming—it's truly unbearable. I’m shaking quite a bit, and unfortunately, my parents aren’t responding to my attempts to reach them for help. I have a history of a chronic heart condition and arthritis, yet I’ve never experienced pain this severe, especially in my spine. For context, I am nearly 15 years old and female. My current medications include pain relievers, anxiety medication, beta blockers, and some vitamins, though those specifics may not be particularly relevant. I don’t smoke; however, I have tried vaping a few times, which might not matter much, but I thought it was worth mentioning as it was requested.
Understanding Atrial Fibrillation and Thyroid Issues: Variability in Cardioversion Decisions
Hello everyone, I’m reaching out for guidance regarding my mother’s current health situation, and I’d greatly appreciate any shared experiences or thoughts. **My mother's background:** - **Age**: 55 years - **Weight**: Recently dropped to 116 kg from 118 kg in just two days, likely due to diuretics. - **Health history**: Previously an underactive thyroid, undiagnosed and untreated, now presenting as overactive. - **Medications**: Currently taking thyroid medication and a beta-blocker (Rapiblock). **Current health status:** My mother has been hospitalized since Tuesday, experiencing **atrial fibrillation with heart rates exceeding 200** beats per minute due to her thyroid's hyperactivity. - The plan for cardioversion was initially settled on Tuesday. However, the following day, the medical team advised postponing it until her thyroid levels could be stabilized, believing that her heart rate would return to normal once her thyroid condition was managed. - Her **obesity** precludes her from undergoing a transthoracic echocardiogram, and due to her thyroid concerns, she cannot handle contrast dye (this has been a consistent issue for over four years). Therefore, the only feasible option was a **transesophageal echocardiogram (TEE)**, which has yet to be performed. - She has been prescribed various medications including beta-blockers and thyroid treatments in the past. - On Friday, a doctor proposed proceeding with cardioversion; however, the attending senior physician objected. - Today (Saturday), another clinician has expressed a desire to move forward with cardioversion, having initiated a new medication, as the senior physician is unavailable. - **Communication has been unclear**, as we were notified of developments by a nurse rather than the physician in charge, causing confusion and anxiety. - Currently, only a **chest X-ray** is scheduled, and the TEE remains unaddressed. **My inquiries are as follows:** 1. Is it common for medical professionals to have varying opinions and frequently revise medication or treatment plans like cardioversion? 2. Is it safe to conduct cardioversion in the absence of a TEE? I presumed that this was a standard procedure to exclude the presence of blood clots. 3. Is it usual practice to have only a chest X-ray prior to moving ahead with cardioversion? 4. How typical is it for patients or their families to not be directly informed about treatment changes and learn about them through nursing staff instead? I recognize that this cannot substitute for professional medical advice. I’m simply trying to discern whether these circumstances are typical or if we should express our concerns more assertively with the healthcare facility. Thank you for your insights!
