hi nishita, thanks for posting
it seems that you have a condition like
polycystic ovarian syndrome characterized by ovarian cysts, irregular cycles,weight gain, acne.
This is a common condition seen in our opd and improves after child bearing
you need to get series of hormonal tests ,thyroid function test, and a gynaecological examination
The important thing to be done is regular exercise to reduce weight which will help decreasing all the symptoms.
hormonal treatment may be suggested by your gynac
for acne use salicylic face wash,
clindamycin and
adapalene creams
get salicylic peels
dont pick the lesions as it may lead to pigmentation and scarring
for
hair fall a balanced diet rich in protein , and
proanagen tablets under your dermat's supervision.
hope this helps you
