I had gastric bypass in October 2021. I had a few episodes where I felt lightheaded. Until yesterday, I was able to recover and it would pass. Yesterday, I felt lightheaded and next thing I remember, I was on the floor. My son heard a something drop (turns out it was me). For clarification: I’m eating more than enough of the right foods and drinking plenty of water. I’m fine just wondering if anyone has experienced this.
