What Is The Treatment For Lightheadedness And Excessive Sweating?

Last night I was cooking and all of a sudden my stomach started feeling warm, I got lightheaded and my face started to sweat. I thought I was going to pass out in the kitchen. I sat down for a little then washed my face with cold water and saw that my face was really pale. After 20 minutes I started to feel normal. Anything I should be concerned about? Thanks.
