Hi, I Am 23yrs Old Female And I Suddenly Grew

Hi, I am 23yrs old female and I suddenly grew fat in a time frame of just 3months without any change in diet and/or physical movements. Its seems like my body is increasing in size and fat from every side. My size has increased by 2sizes and it is still increasing. In spite of doing regular yoga there is no effect on the way I have swelled to a huge size. Please help!
