TG and endothelial dysfunction: Some possible mechanisms that explain the relationship between BMR and blood pressure are as follows: (1) increased activity of the sympathetic nervous system, which can elevates BMR and blood pressure64,65; (2) thyroid hormones levels (T3 and T4) which can affect both blood pressure and metabolism64,66; (3) accumulation of reactive oxygen species (ROS) related to the oxidative stress conditions that can elevate BMR and also increase blood pressure through endothelial dysfunction, inflammation and changes in the regulation of nitric oxide64,67,68.
