That is quite alright, we can leave this question open for days. I want to make sure that we are getting the underlying issue addressed. If you literally are cutting the food into half and we are barely losing weight, this also strongly looks that there is an underlying condition. Also this is going to cause stress to your little one that we are so much trying to get any piece of food possible.
What does he weigh in relation to what his sister weighs?
Despite having his daily ration reduced to less than her, his weight has still remained higher
IF you can describe a little more what you mean by he just seems miserable?
that is all very good what you are doing. What type of food are you feeding now?
I would say that we will need to wait and see the results of the thyroid tests then if you will be able to get those forwarded to me for my review next week. Will that work for you?
Good afternoon. Thank you for sending these to me, I will review now and reply shortly
The Total T4 came out on the low end. This is more diagnostic than the free T4 which can be correlative with the low thyroid. Along with the weight gain despite all of the diet restrictions you are doing. When you read on the above information that when on thyroid supplement the thyroid level should be higher. Also when you look at the normal range for the total T4 levels, it is apparent that we are near the lowest level of detection at 11 when normal level is 15-50 nmol/L. I will be happy to discuss this further with you also. Let me know. I feel if the thyroid level could be increased to even 20 or 30 nmol/L a significant increase to weight loss and activity will be seen.
In cases like this I have had great success in getting the thyroid level increased. When we start on a thyroid supplement we then recheck the blood level in 4-8 weeks, also look at how the clinical signs have responded. If we are clinically doing better when we are on the supplement and the laboratory tests support that we are in the range we want to be, not too low or too high, then we have a good plan forward.
I think that would be a very good idea and will help to decrease any level of anxiety at home with cutting back on the food levels and the food searching. Any other questions I can answer for you now?
The tablets will supplement for what the thyroid gland does not produce enough thyroid hormone potentially, if you stop giving the supplement, then we will return to the previous state again
He weighs approximately 18 kg now?
His full dose would be approximately 0.7 mg total dose once a day, if we are only doing 0.4 mg total dose once a day, I just wanted to let you know we may not see the benefits that we are desiring. Standard base dose is 0.1 mg/4.5 kg twice a day. In the event we do not see the desired weight loss and effects that we desire, I wanted to let you know about this dosing level. Please keep me updated about how things progress.
His total dosage to start with standard dosage would be 0.7 mg (or 700 micrograms, you are using now 400 micrograms) total dosage once a day. This is about a half dosage, in the end the attending veterinarian makes and gives the prescription. I just wanted to discuss dosages with you here. If you look at any online site for starting doses for levothyroxine in Western Countries you will see that. In South America they use the lower dosage as above, do not have as good of response to therapy, and in South America clinicians are now looking to the dosages used in USA. I do hope this answers your question for you.
If we get his metabolism sped up with the levothyroxine, then we can look to be able to lose weight and start to feed more. Perhaps starting with the levothyroxine we can go back to 65 or 70 mg, slowly increase it so we are not so food starved all of the time. Then as we recheck the thyroid level in 1-2 months, see how we are doing with that level and weight loss, we will be able to adjust it upward in time and have a much happier quality of life.
You are more than welcome. Best of success on all of this, Have a good evening. Dr Mike
