Report Bloating in Dysautonomia Discussion Posted September 14, 2015 This may sound odd but, I'm glad to know there are others that have bloating and weight gain. I was feeling rather isolated with this issue. I've had bloating issues off and on for years but, for the past few months, it has steadily worsened. I'm so bloated most of the time that I look bigger than I did when I was 9 months pregnant - I've gained 30 40 lbs in just a couple of months. It seems rather odd but, my MD says I'm not drinking enough liquids and this is causing my body to shift fluid out of my blood vessels. I'm supposed to increase my salt intake, drink 100 ounces of water a day, wear compression stockings, and try to exercise every day Whew! Tall order for an old lady!
