Good morning to you all
Boy am I glad now that I've listen to my gut feeling and did the blood work anyway! Sadly I don't bring a good news.
It looks that Fedja's thyroid is working really slowly. According to my vet the normal range of so called T4 hormone lies somewhere between 21 and 46 and Fedja scores only 9. He is also mild anemic. And the value of urea (has something to do with the kidneys) is slightly high...maximum is 9.6 and he has 9.9, so little dehydrated. Creatinine is good. So kidneys are probably ok, because all of the things mentioned above do happen when dogs are hypothyroid. At this moment everything points out to hypothyroidism.
Next step is to send his blood to the big Pet University clinic here in the country, to check his TSH value. Only if this one turns out to be high then they can say for sure that Fedja has hypothyroidism. I will probably not know it before somewhere begin next week. It's going to be a long week for sure :-(((.
Yesterday I came up with the idea to look on the net for both ataxia (his previous diagnosis made by the neurologist) and hypothyroidism, and to my big surprise I read that in extreme cases dogs with slow working thyroid do get ataxic sometimes!!!
'The diagnosis of hypothyroidism is based on diminished
response to TSH-stimulation in a number of studies [4, 10, 11,
Clinical signs include exercise intolerance, general weakness,
initially mild gait deficits which can progress to paraparesis
or tetraparesis, ataxia
, reduced spinal reflexes and muscle
[1, 4, 10, 11, 12]. Proprioceptive positioning deficits
decreased spinal reflexes are generally more evident in the hind
, however reduced spinal reflexes in all four limbs can occur.'
All things in bold refer to Fedja's condition.
This is just unbelievable. When nothing showed up after MRI-scan was done, why didn't neurologist came up with blood check?! If nothing else only to be sure that there are no other health issues?
I can't help but to think that Fedja has had this thyroid thing going on for a very long time, if not his whole life, and I'm so sad right now I didn't check it earlier. Everyone was telling me that he always was so quiet, and that if he was sick he wouldn't be that energetic outside and eager to go for walks. The only good thing is that it's treatable condition (yes, I'm almost sure of what the results will be) and won't affect quality of his life once we start with medication.
