The Claim
Hypothyroid dogs exhibit higher basal serum concentrations of growth hormone (GH) and insulin-like growth factor-1 (IGF-1) compared to euthyroid dogs, and this elevation may contribute to reduced insulin sensitivity in hypothyroid dogs.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Dogs with an underactive thyroid might have higher levels of certain growth hormones, which could make their bodies less responsive to insulin.
See the scientific wording
Hypothyroid dogs have higher basal serum concentrations of growth hormone (GH) and insulin-like growth factor-1 (IGF-1) compared to euthyroid dogs, which may contribute to the observed reduction in insulin sensitivity.
What the research says
1 studyStudy: Effect of hypothyroidism on insulin sensitivity and glucose tolerance in dogs.
The study found that dogs with low thyroid function have higher levels of growth hormone and IGF-1, and also handle insulin worse, which supports the idea that these hormones might be part of the problem.
