My mother (aged 65) is suffering from Hypothyrodism for 6 years now. She is taking Thyronorm 100mcg once daily. Now her TSH is almost at the lower level (0.98) but T4 is very high (21.0). T3 is within normal range. Since she has started treatment on hypothyrodism, her T4 is always on the higher side - 14, 15 and now 21. Once doctor suggested her to lower the dosage of Thyronorm to 75mcg, but doing this increased the TSH. She feels fatigued and has lost lot of weight in last 5 years. She has developed a minor lump also on her throat recently.
Hi. Thanks for your query. Read and understood the history of Hypothyroidism and taking Thermoform for the last 6 years by your mother. Thermoform is a replacement hormone T3 and T4 are produced by the thyroid glans. But the TSH is produced by Pituitary gland, and it produces it in response to the feedback from the circulating thyroid hormones sensed by it. Hence, are the change. When the pituitary feels that the bodies levels of thyroid hormone is reduced, it will produce more to give an order to the thyroid gland to produce more. Hence, it is more important to know and keep the levels of the thyroid hormones under normal range. You have to reduce the dose of Thermoform, as it is more dangerous to keep the T4 levels in the high range, it will affect the whole body.
