Hello! I am a male, 22 years old and have been eating vegan for nearly 3 months. When I went vegan i immediatly started to feel a lot better, happier, healthier and so on, but for these last two weeks or so I have been getting some very worrying symptoms and I wonder if they could be related to my diet. I have started getting a lot of heart palpitations and anxiety almost 24/7 leading to extreme insomnia. I also feel alot of muscle tension and fasciulations especially in my legs, and i am starting to feel very depressed and unhappy because of this. These are all symptoms ive experienced before in my life even as a carnivore, theyve just gotten alot worse now. I went to the doctor to check this up and told them about my vegan diet and they took a bunch of blood tests. Zinc, magnesium, d-vitamin, b12, was all fine, only iron was a bit low. They say everything is fine and that the symptoms im experiencing is probably due to anxiety/stress. I have been eating very strictly and these are basically all the foods i have been eating daily: lentils, sweet potato, white rice, tofu, broccoli, quinoa, oats, berrys, banana, cashew nuts, almond butter, watermelon, pineapple. Supplements: vitamin b12 and D-vitamin. Now my question is, can I be 100% sure that these tests are accurate and that its not my diet thats causing these problems after all? I really dont want to go back to eating meat, but these symptoms im experiencing are so intense that I almost cant believe that its just mental issues and stress. It sounds to me very similar to vitamin b12 defiency and I know about pernicious anemia but the blood test shows that i am not deficient in vitamin b12 so it cant be the case, right? Extremely grateful for your thoughts and help!!
