Thanks for the query.
As only part of fallopian tubes are cut during the tubectomy, that will not usually cause any of the problems you mentioned.
Tubes only carry the function of transferring the ovum, sperm, zygote. And they are not concerned with hormonal
production, so hormonal imbalance, weight gain etc will not occur with this.
Severe pain during periods
can occur when there is pelvic inflammatory disease
, this can occur in normal cesarean also(not in all cases) tubectomy will not increase the chance.
As you are going to complete the family better to go for tubectomy.
