Hi, my friend who is 52 years old, had a heart attack several years ago and has very low blood pressure since she was a child. She is now experiencing dizziness often. But today, it s different. She s has had several dizzy spells and now is sweating. With this dizzy spells, she feels nausea. She won t listen to me and I m really concerned. I know that when her blood sugar drops and she eats, shes better. Today, it s not going away.... I felt her face and it wasn t cold or clammy, just sweating
