You have undergone total hysterectomy
and you are suffering from migraine

) you are taking right now.weight gain is one of the side effect of Estradiol.need not bother. there is no need to change your diet.follow the same quantity of food but at intervals.(example- same quanity split into 5 times a day instead of 3 times) and increase your physical activities.this will definitely solve your issue.
