<s>[INST] I just was singing in my vocal class at ECU, I m in musical theatre. I don t usually eat in the morning, so I didn t today. I was just now signing with the group and I started feeling slight nausea that started to persist. I started getting really hot and sweating all over my torso, arms, and head. I felt light headed and possibly like I was going to throw up. I say down for a moment. After only a few minutes I was basically fine. I m in another class now and feel a little light headed and something somewhat in my stomach . What s going on right now? [/INST] Hi, Thanks for writing to health care magic. Never miss your breakfast. You should cultivate  a habit of having some thing in the morning. You already take a fast of around 12 hrs when you do not eat any thing overnight and going on work with out having any thing is going to cause problems. Prolonged fasting can be responsible for gastritis which could be responsible for various problems you are facing like nausea etc. What is your age? Did you ever have your blood sugar or blood pressure checked up? Please reply in detail so that we can help you better. Take care. </s>
