To : To answer your question, any extreme or drastic change in weight ( increase or decrease )can affect your hormones thus altering your cycle.

Yes: After a surgery like the sleeve it not uncommon for your hormone balance to be thrown out of whack. So it is not uncommon for you to have breakthrough bleeding with your iud. As you get farther out from surgery your hormone levels will normalize.

Weight loss hormone: Rapid weight loss from any method can cause hormonal changes. Surgeons are just starting to study this in patients undergoing weight loss surgeries. The peripheral adipose tissue typically increases estrogen levels in men and women, so, with rapid loss of adipose tissue, men can experience rise in testosterone levels and women, changes in estrogen levels as well. The rate depends on the patient.
