 [ Symptoms ] i am a 44 year old woman with very swollen stomach has been like this for 4 months [ Disease ] if you have so much distention in your abdomen and no tests are diagnostic of anything specific then it can be due to excessive gas formation or bloating secondly if you have an ovarian cyst then it can cause hormonal imbalance water retention that can also cause stomach to swell so it is advisable to get a thorough hormonal profile done with a transvaginal sonography and consult a gynaecologist if it is due to weight gain or bloating then regular exercise diet modifications and appropriate medication for gas like simethicone can help hope this helps
