Hello everyone, I am a doctor, I am 47 years old and after vaccines and 3 episodes of covid I began to have tachycardia, abdominal distention, gastric distention, minutes after eating, several times I had to go to the emergency room. They did an edoscopy where they only found moderate gastritis and duodenitis. As I began to follow a diet, I noticed that histamine-releasing foods were harmful to me, so I gradually eliminated them. This helped me reduce tachycardia. Foods such as shrimp, strawberries, apples, and bananas became intolerable, since they produced redness. in my face tachycardia of up to 160 per minute. I thought I had a deficiency of the enzyme diamine oxidase, and I bought supplements for that, I really don't know if it helped me, because I removed food at the same time as taking the enzyme. Afterwards I noticed a tolerance to milk and cheese, also an intolerance to almonds and peanuts, walnuts, cashews. I stopped eating them because they caused me abdominal, epigastric and mesogastric pain. Later I also noticed that gluten was causing me abdominal pain so I eliminated it little by little. I lost a lot of weight, but it helped me to increase my consumption of lean meat. I have noticed that corn does not produce symptoms, nor does avocado or egg. I already went to several gastroenterologists and the medications that worked for me were mirtazapine, esomeprazole, colchicine, and to reduce the anxiety and nervousness of helplessness because my other colleagues don't know much about it, I take 3 drops of clonazepam at night. I am also being treated with homeopathy, carbo vegetabilis, lycopodium clavatum, arasenicum album, nux vomica, china off, etc. I know that many doctors know things that they have seen in patients, but they just want to spread the word because there is a lot of economic benefit from what is happening. I hope that science and the great human values that still remain will end up coming out to defend the causes of those affected and everyone will move forward from these consequences.
