Any surgery involving a glagnd decreases the mass and function of the gland..In your case left lobe has been removed causing less amount of thyroid tissue.. Lesser the tissue lesser would be the amount of thyroxine secreted
Now our thyroid gland by secreting Thyroxine has a negative feed back in pituitary to secrete TSH meaning a lesser amount of thyroxine post surgery will have lesser negative feedback on pituitary leading to increase in levels of TSH
