It is important to note that obesity itself is associated with higher TSH levels.
The Mechanism is as follows:
Increase fat --> Increase Leptin --> Increase of TRH --> Increase of TSH
Hence it is imperative to use the correct cut-off before making a diagnosis of Subclinical hypothyroidism in an obese individual
So why is the increased TSH considered normal instead of considering it as obesity induced hypothyroidism sir?
