After block and replace therapy for hyperthyroidism a couple of years ago which resulted in stablising my thyroxine production, recent bloods showed that I had become 'termporarily' hyperthyroid post virally. A second test revealed more stable bloods, henece the 'temporary' conclusion by my GP. I am back to 6 weekly bloods and my most recent test (3 weeks ago) indicates that I am 'borderline' hyperthyroid. I wondered if there's anyway I can help myself nutritionally to avoid becoming hyperthyroid again ie through diet, supplements, avoidance of triggers etc.. Also, what does 'borderline' actually mean? I am currently asymptomatic.
