Weight 139lbs 4 days ago. now at 132lbs today. been eating fine and drinking plenty of fluids. slight nausea & uneasy stomach at times. no other sympt?

Weight loss: 7# weight loss in 4d is rather dramatic. Since you've been eating fine & drinking plenty of fluids, I'd question the accuracy of your scale/weight. Perhaps you were weighed on different scales? Don't bother comparing weights unless from same scale in same state of clothing. Lots of causes of "slight nausea & uneasy stomach". See your Family Doc if this persists. And/or if weight loss is real.
