Hi there. A low T4 usually signifies an underactive
thyroid gland (hypothyroidism), but interpreting it accurately requires looking at your
TSH and Free T3/T4 levels together.
It is not immediately dangerous, but leaving true hypothyroidism untreated can cause sluggish metabolism, fatigue, cholesterol abnormalities, and weight changes. If confirmed, it is very easily and safely treated with standard daily thyroid hormone supplementation.
To interpret your full thyroid report and get a customized treatment plan with a valid prescription, feel free to book a direct consultation with me on Practo, or reach out directly on WhatsApp at six three six nine four six zero five seven seven.
