The expression "sick to your stomach" is used when you feel unwell and nauseous (like you might vomit). You might use this expression when you have eaten something that doesn't agree with you, or when you are experiencing anxiety or stress. For example, you could say "I ate too much pizza and now I feel sick to my stomach," or "I'm so nervous about my exam that I'm feeling sick to my stomach."
