摘要
The IGB （intragastric balloon） is a silicone device, inflated by endoscopy in the gastric cavity, with physiological saline and a blue dye, up to the volume of 700 mL, and used for a maximum of 6 months, It is indicated for patients with BMI〉27 kg/m^2 that have not undergone previous gastric surgery. In obese women there is a decrease in peripheral resistance fertility, and the weight loss achieved in bariatric surgery improves fertility due to reduced subcutaneous fat, with lower insulin resistance. Similar results could be achieved through the use of IGB, a less invasive method. The objective of the article is to report the case of a patient who became pregnant using IGB, considering the hypothesis that the increase in fertility was due to weight loss and/or due to the improvement in the self-esteem （and sexual life） of patient. We selected 13 articles from PubMed, UpToDate, JAMA and a case report. Results： Balloon with drawal occurred on 05/02/16 after positive pregnancy test with final weight 65.5 kg and BMI 25.91 kg/m2. Conclusions： Weight loss actually favors fertility, but self-esteem may have been instrumental in improving the sex life, enabling conception.
