There are three possible conditions for post-transplantation bloating: in the first case, multiple follicles develop during ovulation promotion and symptoms of ovarian hyperstimulation occur, such as abdominal distension and pain, increased ascites, enlarged ovaries, dyspnea, and oliguria. This symptom, usually occurs about one week after egg retrieval. In the second condition, the embryo feels tingling in the abdomen, back pain and abdominal distension at the time of implantation, and a few patients may also experience a small amount of vaginal bleeding. In the third case, reduced activity after transfer, gastrointestinal dysfunction and indigestion leading to abdominal distension. You can increase the activity appropriately, pay attention to eating easily digestible food, drink more water and eat more vegetables and fruits to avoid causing gastrointestinal distension. If the bloating is serious, go to the hospital for follow-up to rule out the bloating caused by ovarian hyperstimulation.
