Background
Women with a history of bariatric surgery are recommended to avoid pregnancy at least 12 months after surgery. Evidence on the impact of bariatric surgery on contraception, menstrual cycle, and sexuality in the first year postoperative is therefore indispensable.
Objectives
The objective of this paper is to prospectively study changes in contraception, menstrual cycle and sexuality in women of reproductive age following bariatric surgery.
Setting
The study was conducted in two secondary medical centers and a tertiary academic medical center.
Methods
Women attending for bariatric surgery or who recently underwent bariatric surgery completed online questionnaires about contraception, menstrual cycle, and sexual behavior before surgery and 6 and 12 months after surgery.
Results
The study included data from 71 women, including 70 and 47 women at 6 and 12 months after bariatric surgery, respectively. Preoperatively, 43.6% (n = 31/71) used a short-acting hormonal contraceptive, the usage of which decreased significantly to, respectively, 32.8% (n = 23/70; p = .031) and 27.7% (n = 13/47; p = .022) 6 and 12 months post-surgery. Usage of long-acting contraceptive methods increased from 26.7% (n = 19/71) preoperatively to 38.6% (n = 27/70; p = .021) and 42.6% (n = 20/47; p = .004) at 6 and 12 months. Combined oral contraceptives (COC) remained used (39.4% preoperatively, 27.1 and 14.9% at 6 and 12 months postoperatively). Menstrual cycle (frequency, pattern, duration of the cycle, and the menstruation itself) and sexual behavior (intimate relationship, frequency of intercourse, and satisfaction) did not differ significantly before and after surgery.
Conclusions
Women undergoing bariatric surgery appear to switch their type of contraceptive from oral, short-acting hormonal contraceptives to non-oral, long-acting contraceptives. No changes in menstrual cycle and sexual behavior were shown.
