<human>: My friend is having fleeting nausea. It is moderately intense: he sweats and feels as if he is going to vomit. Vomiting has occurred on a few occasions. He said that he feels better when he eats something: the nausea seems to go away almost instantly. Please point me in a general direction to assist him in his symptoms until he can get an appointment date with his primary care physician. Thank you so much!
<bot>: Hi, Thanks for writing in. If your friend is having symptoms of nausea and sweating which shows improvement on eating then conditions like low blood glucose and anxiety related stress are to be investigated in detail. What happens is there is a possibility of the blood sugar level going down to sub normal and then this causes decreased glucose metabolism in the brain and other organs. While slight low glucose in blood might be tolerated for a short time, longer durations of hypoglycemia can cause dizziness, weakness, nausea and sweating. It is important to eat well and take adequate amount of nutritious foods rich in vitamins and proteins. If his food intake is normal then he should get investigated for any malabsorption syn Chat Doctor.  He should also relax and stay stress-free and have small meals at short intervals.
