For early pregnancy, especially with a history of miscarriage, doctors generally prefer your TSH level to be below 2.5 mIU/L. Your level of 3.15 is just slightly above this target. Since you are currently taking Thyronorm (levothyroxine) at a very low dose of 12.5 mcg, your doctor may want to slightly increase your dose to bring your levels into the ideal range. Please don't worry, as this is a very common and easy adjustment. Please share these results with your doctor soon so they can safely guide your care.

A TSH level of 16 indicates your thyroid is underactive. To help it work properly, you will likely need levothyroxine, the generic name for Thyronorm. The exact dose of Thyronorm you need is highly personalized. It depends on factors like your weight, age, and overall health, and is typically started at a low dose and adjusted gradually. Please consult your doctor, who will look at your complete health profile to safely prescribe the perfect starting dose for you. We will get this balanced for you soon.

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.

First, ensuring your Thyronorm (levothyroxine) dosage is optimal through regular thyroid function tests is key. For weight and PCOS management, a balanced, low-glycemic diet rich in whole foods, paired with consistent moderate exercise, works wonders. For irregular periods and hair loss, targeted medical therapies like insulin-sensitizing agents or specific hormonal treatments can be highly effective. I warmly recommend discussing a coordinated care plan with your endocrinologist and gynecologist to safely address these symptoms together.

Cough and fever for a few days are often due to an infection, but taking multiple medicines together should be carefully monitored. Since you are already on Thyronorm and have a sulpha allergy, it is important not to add or change medicines on your own. Continue resting, stay well hydrated and take light meals to support recovery. Watch for symptoms such as an increasing fever, breathing difficulty, or weakness. Consult your doctor to review your current treatment and ensure it is safe and appropriate for you.

It is reassuring to see that your TSH level of 0.70 is in the normal, healthy range, which shows your daily 100 mcg of Thyronorm (levothyroxine) is working well to keep your thyroid stable. A slightly elevated T4 with a normal T3 and TSH is actually quite common and usually not a cause for concern. For now, it is generally safe to continue your current dose. However, please share these results with your doctor, who will look at how you are feeling overall to decide if any small adjustments are needed.
