An interesting case report - though the conclusion maybe somewhat speculative. Don't take it too seriously without further reports. I shall certainly continue to consume my modest but regular consumption of celery.
It is a classic to suggest that it takes more calories to eat and digest celery than it supplies!

After cessation of consumption and treatment with methimazole, the symptoms remitted. Then, the medication was discontinued when the lab tests and ultrasound were normal and indicated the patient’s definite recovery. In 2 months follow up of, he was normal and thyroid-stimulating hormone (TSH), T4, T3, anti-TSH receptor, anti thyroperoxidase and antithyroglobulin were in normal ranges.
Hyperthyroidism may be induced by consumption celery. Although many studies have reported side effects such as allergic reactions for this herb, this is the first report of hyperthyroidism induced by celery in which the patient recovered after discontinuing the medication.
