I saw your original post and even though it is older I thought I would ask you this. I have not had gastric surgery of any kind. I do have a moderately sized hiatal hernia since at least 2002 which has not been a problem and also have barrett's esophagus. I never felt that I had reflux but my GI doctor says it is silent and that many people have it that way. I am on omeprazole 40 mg twice a day. I do notice sometimes if I eat anything too close to bedtime and don't prop up my head I have some reflux. Recently I started having the symptoms described by you and others here. That is, almost like clockwork as I take my last few bites of dinner, I am sweating profusely. I also begin to feel nauseated. It doesn't last long. Often a few sips of ginger ale will help. I also don't throw up or anything. I notice some belching recently which is not normal for me but it could be the ginger ale. Sometimes I take a pepsid. Today it happened after lunch and I just had to lie down. I don't notice that it is related to any particular food but I do often have a small bit of sugar free greek vanilla yogurt as dessert after dinner. I know that sometimes I will have trouble swallowing it. I has a barium swallow test and it showed mild esophageal spasms. Doctor gave me some medicine for it but I didn't like it (can't remember why as it was a while ago). He told me to stop taking it and that the spasms weren't dangerous just a common symptom of someone with barrett's and hiatal hernia. The swallowing issue doesn't happen all the time so I just don't worry about it. But the sweating and nausea has me concerned. I have been hesitant to go to the doctor because of COVID-19 but am due for my endoscopy to check my barrett's. I have gained a bit of weight (maybe 20 pounds) over the last 2-3 years due to back problems. Am largely a healthy eater (don't eat much meat at all just every so often) but I do have something sweet just about every day (usually a bran muffin that helps me to not be constipated from pain meds for my back). Any thoughts please send them my way. If I am posting in the wrong place, please redirect me.
