Boris has hyperthyroidism. He’s on thyronorm in ever increasing doses. His behaviour is improved - he’s more like his old self (less trotting round the cage and more lounging like he used to do). The rapid weight loss has stopped, and his vitals (heart rate and breathing rate) are improving; he’s no longer absolutely ravenous but there’s no weight gain. Each time the dose increases his weight plateaus, then he gains a few grams and then he loses a few more than he gained, and so it goes on in a downward trend. He’s been having top up feeds of Emeraid to help with the weight loss but the weight loss still continues. Just looking to see if this is others’ experience of hyperthyroidism and thyronorm.
