The Link Between Miscarriage and Hashimoto's Disease
I am a 23-year-old woman who recently went through a heartbreaking experience—my first pregnancy ended in a miscarriage at just 4 weeks. This has brought about considerable emotional distress for me. I have been living with Hashimoto's thyroiditis since my teenage years, and I am currently prescribed 88mcg of levothyroxine to manage my condition. Three days before discovering my pregnancy, I had my thyroid stimulating hormone (TSH) levels tested, which came back at 3.3. Now, I find myself questioning whether my Hashimoto's could have played a role in my miscarriage. I have encountered mixed feedback regarding this issue; some medical professionals suggest that my thyroid condition may indeed be a contributing factor, while others argue that the early stage of my pregnancy increases the likelihood of a chromosomal issue with the fetus as the primary cause. I have scheduled an appointment with my endocrinologist to explore the possibility of adjusting my levothyroxine dosage, especially since my husband and I are eager to conceive again. I am seeking insights from others who might have faced similar situations or who can offer advice on how to proceed in order to minimize the risk of another miscarriage in the future.

I'm truly sorry to hear about your recent miscarriage and the emotional distress you are experiencing. It’s understandable to have questions about how your Hashimoto’s thyroiditis might relate to this loss, especially as you look toward future pregnancies.
Main Points:
- Hashimoto's can affect pregnancy but is not always directly linked to miscarriage.
- Maintaining optimal thyroid levels is essential for a healthy conception and pregnancy.
- You’re taking a proactive step by consulting with your endocrinologist.
Explanation: Hashimoto's thyroiditis can impact fertility and pregnancy outcomes, primarily through its influence on thyroid hormone levels, which are critical for fetal development. Generally, abnormal thyroid hormone levels can contribute to complications. However, miscarriages are often complex, and while your thyroid condition plays a role, many miscarriages occur due to chromosomal abnormalities in the embryo, particularly early on.
Your TSH level of 3.3 is within the normal range for most people, but during pregnancy, some guidelines suggest aiming for a lower target (around 2.5) to support fetal health. This indicates that your current thyroid management may need to be reassessed, which you’re planning to discuss with your endocrinologist.
Next Steps:
-
Discuss Thyroid Management: During your appointment, focus on reviewing your TSH levels in relation to pregnancy. Discuss the possibility of adjusting your levothyroxine dosage to ensure optimal thyroid hormone levels when you conceive again.
-
Emotional Support: It's important to address the emotional aspect of your experience. Consider speaking with a counselor or joining a support group for women who've experienced similar situations.
-
Healthy Lifestyle Choices: Prioritize a balanced diet rich in nutrients (including iodine, selenium, and vitamin D) that support thyroid health. Regular exercise and stress-reduction techniques, such as mindfulness or meditation, can also be beneficial.
-
Monitor Symptoms: Keep an eye on any symptoms related to your thyroid; if you notice significant changes, such as fatigue, weight changes, or mood swings, bring these up with your healthcare provider.
-
Plan for Future Pregnancies: Once you receive guidance from your endocrinologist, begin preparing for your next pregnancy by maintaining health and possibly addressing any additional prenatal care needs.
Your experience is valid, and it’s commendable that you're seeking the right care and information. Please take it one step at a time and focus on both your physical and emotional well-being. Let me know if you’d like more details on any specific aspects.

When to Seek Medical Advice for Prolonged Bleeding on Combination Birth Control
I’m a 26-year-old female, standing at 6 feet tall and weighing around 80 kilograms. Recently, I initiated a regimen with Oralcon, which is a combination birth control pill. I began my course on the first day of my menstrual cycle as recommended, but now I find myself continuing to bleed for the past week. Unlike mere spotting, the flow resembles that of a typical period. Generally, my menstrual cycle consists of three days of heavy bleeding followed by two days of lighter discharge. When would it be appropriate for me to return to my healthcare provider for a consultation? Additionally, I’m curious to know if discontinuing the pill would lead to a cessation of this bleeding. I have encountered various opinions suggesting this might be the case.
Understanding DILI and Its Impact on Pregnancy
Hello, I know this might be an unusual request, but I’m really seeking some guidance here. I’m a 31-year-old woman and I’ve been experiencing some health issues. For the past two and a half months, I was on a medication that unfortunately caused a drug-induced liver injury. Once I discontinued its use, I noticed that my symptoms began to improve, and my liver function tests showed significant recovery. By December, my liver numbers were quite favorable, and I was symptom-free. In December, my menstrual cycle was lighter than usual, but within the expected duration. However, I noticed the next two cycles in January and February were extremely light, almost negligible. My healthcare providers indicated that hormonal changes due to the liver injury could be impacting my periods, which I understand. Additionally, my partner and I have been trying to conceive for some time. Though I paused efforts because of my recent health challenges, I just tested with ovulation strips for the past week, and they haven’t shown the expected darkening in line intensity as they typically do during ovulation. This has led me to believe that my body is still in the process of readjusting after the medication. So, my question for anyone who might have experienced something similar is: How long did it take for your ovulation and hormonal levels to return to normal? Any insights or experiences would be greatly appreciated!
Considering Marriage and Family Planning with a Partner Born with Cleft Palate
When contemplating a relationship with a man whose birth condition includes a cleft palate, especially in the context of a family where his half-sister also shares this condition among seven siblings, concerns may arise regarding the implications for potential offspring. Particularly if there is no historical precedent of cleft palate in the family lineage, one might wonder about the safety of marrying him and starting a family together. What steps can be taken to ascertain the safety of such a decision? It’s essential to engage in thorough discussions with healthcare professionals who specialize in genetics or family health. Genetic counseling could provide valuable insights into the risk factors involved and guide the testing process. Additionally, there are specific assessments and screenings that can be undertaken before making decisions about having children. Consulting with a geneticist can inform you about potential hereditary risks and the likelihood of passing on conditions like a cleft palate. These professionals can also discuss preventive measures that could mitigate the chances of similar issues arising in future generations. By gathering detailed information and engaging with qualified specialists, you can make an informed decision regarding marriage and family planning.
Concern Over Dog Encounter During Pregnancy
Greetings, I’m seeking some advice... I'm a 29-year-old woman who is currently pregnant and dealing with anxiety. My medication includes a reduced dose of 50 mg of sertraline—I used to take 150 mg, but I find it difficult to tolerate at that level. Additionally, I’m taking prenatal vitamins, aspirin due to a history of elevated blood pressure while expecting (although I'm stable at present), and daily allergy medications along with a budesonide inhaler to manage my chronic asthma. Recently, while standing, a larger dog jumped on me. I am at the 13-week mark in my pregnancy. Although I was taken aback by the sudden impact, I did not feel any pain during or after the event. There were no signs of bleeding, cramping, or anything concerning. Initially, I brushed it off since I often dog sit, but my worries about the baby started to creep in. Given that I have heightened anxiety, particularly during this pregnancy, I'm struggling with nausea that makes it difficult for me to take my anxiety medication. I spent some time searching online for reassurance, finding that signs of something being wrong would include severe abdominal pain, cramping, or bleeding—all of which I am not experiencing. I hope anyone with experience can provide some comforting words. I understand that the little one is small and well-protected, yet I can’t shake my worries about the health of my baby.
Is It Time for Me to Receive the HPV Vaccine?
I am a 20-year-old female, and I wanted to share my experience regarding the HPV vaccine. When I was younger, my country offered a vaccination program, but my parents decided against it due to some public controversy surrounding the vaccine, so I missed out at that time. Now that I am in my second year of medical school in Europe, I've been reflecting more on the implications of not having been vaccinated against HPV. As I delve deeper into my studies, I can't help but worry about the potential long-term effects of not having this protection. To date, I've not engaged in any sexual activity, nor have I had any exposure to others' mucosa, leading me to believe I'm still a suitable candidate for the vaccine. One of my main concerns, however, is the expense involved. Since I'm now over the age where the vaccine is provided at no cost, I'm faced with having to pay for it myself. While the fee isn’t exorbitantly high and I can afford it, as a student, I would prefer to allocate my finances elsewhere for the time being. Still, I’m torn between wanting to avoid unnecessary health risks and delaying the vaccination until I have a better income. Is it worth waiting a few more years? Ultimately, I'm seeking some guidance and encouragement on this matter.
