I went through that same thing about 6 years ago. I literally went from 110 lbs to 140 in less than a week. Talk about scary. My doctor at that time said it was from stress. Another said that it was from MS.
Still have no clue as to what it was,but when I think back now it seems to me it could have been stress.
My mother had sudden weight gain and found out she was diabetic. My aunt had sudden weight gain with menopause.
If you're pregnant it could be toxemia,or pre-eclampsia as they now call it.
Have you had your thyroid tested?
There are many possibilities that exist.
I wish you luck on finding your answer.
