A TSH of 5.99 after stopping Thyronorm shows her hypothyroidism is coming back. The safest approach is to restart the same dose she was taking before, take it daily on an empty stomach, and not change the dose on your own. Her doctor can check TSH again after 6 to 8 weeks and adjust the dose if needed.

Yes, your T4 level is fine. In the first trimester of pregnancy, the goal is to keep TSH below 2.5 to 3, and your TSH at 2.69 is within the acceptable range. Your T4 value (12.07) is also within the normal range for pregnancy, which means your current Thyronorm dose is working well. Continue taking the medicine regularly and repeat thyroid tests every 4 to 6 weeks, as dose adjustments are sometimes needed during pregnancy.

A TSH of 7.4 indicates underactive thyroid (hypothyroidism), which can cause symptoms like fatigue, muscle aches, and body pain. You should see your doctor, as your thyroid medicine may need a dose adjustment. Meanwhile, gentle exercise, good sleep, and pain relief as advised by your doctor can help ease discomfort.

A TSH of 19.64 is high, which means your hypothyroidism is not well controlled right now, even though FT3 and FT4 are near the normal range. This can happen if the Thyronorm dose is too low or if doses are missed. You should see your doctor soon for a dose adjustment, and repeat TSH after 6 to 8 weeks. Do not stop or change the dose on your own, as proper control is important for your health.

Unintentional weight loss of 9 kg over two years, along with weakness, should not be ignored, even if your hypothyroidism appears to be well controlled. Although thyroid-related issues can affect body weight, weight loss can also occur due to several other causes, such as inadequate nutrition, nutritional deficiencies, gastrointestinal disorders, malabsorption, diabetes, chronic infections, or other underlying medical conditions. Since your TSH levels have been mostly within the normal range, the weight loss may not be solely related to your thyroid condition. It is important to consult your doctor for a comprehensive evaluation to identify the underlying cause. This may include blood tests, nutritional status assessment, and evaluation of your long-standing gastrointestinal symptoms. Do not change the dose of Thyronorm or any other prescribed medication without medical advice. A proper diagnosis is essential to determine the most appropriate treatment and management plan.
