Since your TSH levels are already low on 175 mcg of Thyronorm (levothyroxine), increasing your dose is not safe and could cause harmful side effects like heart palpitations. Sometimes, a low TSH means your body is already at its limit for thyroid hormone. I gently suggest discussing this with your doctor to check your free T3 and T4 levels, and perhaps explore other metabolic or hormonal factors that might be slowing your progress.

Thyronorm (levothyroxine) is indeed the correct medicine to help treat this. However, experiencing a pounding heart and severe nausea can suggest that your current dose of 88 mcg might be a bit too high for your body right now. Please don't worry, but I highly recommend reaching out to your doctor promptly. They can easily review your symptoms, perhaps recheck your blood levels, and safely adjust your dose so you can start feeling much more comfortable and like yourself again very soon.

I completely understand your concern about whether your 100 mcg Thyronorm (levothyroxine) dose is correct. To give you the most accurate advice, I would need to see your specific thyroid lab results, particularly your TSH levels. Please do not lower your dose or stop taking your medication on your own, as sudden changes can cause your thyroid levels to fluctuate and make you feel unwell. I highly recommend sharing your test results with your doctor.

Levothyroxine (Thyronorm) is completely safe to take while breastfeeding, as only minimal amounts pass into breast milk. Since 25 mcg is a very low dose and gestational hypothyroidism often resolves after childbirth, you may not need lifelong treatment. However, please do not stop taking your medication without consulting your doctor first. They will likely guide you on how to safely trial stopping the medication and monitor your blood levels afterward to ensure your thyroid remains healthy. Following up with your doctor will keep you feeling best

Since you are taking Thyronorm (levothyroxine) for hypothyroidism, it is possible your thyroid levels need a slight adjustment; even a minor imbalance can stall weight loss. Additionally, certain blood pressure medications can slow metabolism or cause mild fluid retention. At 47, natural hormonal shifts can also play a role. Please don't be discouraged. I highly recommend consulting your doctor to check your thyroid levels and review your blood pressure medication.

Yes, starting Thyronorm (levothyroxine) can temporarily cause your period to be late. Thyroid hormones directly regulate your menstrual cycle. When you begin treatment to correct a thyroid imbalance, your body undergoes hormonal adjustments, which can temporarily disrupt your cycle timing. This is usually a normal part of your body adjusting and should stabilize soon. However, since a delayed period can also be due to stress or potential pregnancy, I recommend taking a home pregnancy test if applicable.
