Thyroid Test: Three Stories That Started With Fatigue

Marina, 34 years old
After the birth of her second child, Marina felt constantly tired, was cold even in warm weather, and began to gain weight despite dietary restrictions. A chance visit to the therapist ended with a referral for a blood test for TSH. The result: elevated TSH and reduced free T4 — classic hypothyroidism. Marina started taking levothyroxine and within a month noticed an improvement in her well-being.
What was decisive:
– easy, but prolonged symptoms
– TSH level as a primary marker
– timely diagnosis without complicated examination
Alexander, 42 years old
Oleksandr noticed that his heart palpitations became more frequent, he felt anxious, and his body weight decreased, despite his usual diet. After consulting a cardiologist, he had his thyroid hormone profile tested. The results: decreased TSH and increased T4. Ultrasound did not reveal any nodules, but TPO antibodies were extremely high — the doctor diagnosed autoimmune thyroiditis with a hyperthyroid phase.
What was decisive:
– cardiological symptoms, that were not age appropriate
– verification TPO antibodies, which revealed an autoimmune nature
– combination hormones and ultrasound for the full picture
Natalia, 57 years old
Natalya had no symptoms. It was only during her annual physical examination that the therapist discovered a lump in her neck during palpation. An ultrasound confirmed the lump was over 1 cm in size. The woman did not experience any discomfort, but tests showed normal TSH and T4. After a fine-needle biopsy, a benign adenoma was found, which does not require surgery, only regular monitoring.
What saved me from progression:
– attentive doctor during the examination
– Ultrasound and tests to assess function and structure
– distinction between node and hormonal disorders

What unites all three stories
Although the symptoms and circumstances are different, all three patients went through one key stage — thyroid hormone testing. The main markers used in laboratory diagnostics:
TSH — thyroid-stimulating hormone, the control center of thyroid gland regulation
T4 free — the main hormone of the gland that affects metabolism
T3 free — less stable but more active hormone
Antibodies to TPO (AT-TPO) — indicate autoimmune processes
Antibodies to thyroglobulin (AT-TG) — used as additional markers
Thyroglobulin — cancer marker in postoperative patients
When to take the test
at chronic fatigue, weight changes, mood swings
at hair loss, dry skin, brittle nails
at rapid pulse, shivering, feeling hot
before pregnancy or IVF
if a family history of nodules or autoimmune thyroiditis
To ensure accurate analysis:
surrender in the morning on an empty stomach
do not take drugs with iodine or hormones without consulting a doctor
don't smoke, don't drink coffee before delivery
The thyroid gland works silently — but its malfunctions can affect everything from mood to heart. One test can reveal something that has long remained in the shadows. And as these three stories show — timely diagnosis changes the quality of life.
