Can Withdrawal From Diance Cause Hair Loss And Weight Gain?

i am 24 years ols, 5 3 weigh 68 kgs and suffer from PCOD. My paternal side also has this problem so it might be hereditary. I am on Diance35 since past 5-6 years. Is it harmful? I have normal periods now. My just had my blood test reports and everything is normal except that my T4 is a little on higher side. I had a lot of hair loss which i guess was the time when i left Diance for a long time in between. Whats going on? I want to lose weight. Please suggest a drug or anything? Does PCOD ever get normal or would i be on pill support everytime for periods?
