Hi dear ,
I understand your concern
It is true that obesity causes harmonal changes .the fat stored in our body releases harmones and also
testosterone etc are converted to estrogen . So it adversely affects your cycles
also
thyroid is next common thing that causes obesity and irregular cycles .and it's very common almost 25% of women suffer from thyroid disease
Next Steps
please get evaluated for PCOS
get
Sugar test (FBS )
THYROID PROFILE (
TSH,T3,T4)
scan for endometrial thickness
