Raised ESR can be due to associated anemia with irregular periods
Also if you got your blood test
done during menses then it also affects your ESR values causing it to be higher.
The irregular periods you have with obesity can be well explained by PCOD.
However getting a thyroid
function test is also a must. This because both irregular periods and raised ESR are seen with thyroid disorders.
Anemia can also affect your cycles.Weight loss
is a key to solving your problem of irregular menses apart from the treatment you take.
The success of any treatment for regularizing periods is dependent on reducing the excess weight you have.
Regular exercise with balanced diet will ensure this.
