Episodic vomitting. Along with this.

Pls help if anyone can. Last one and half year I am facing this issue. 2023 April first time I vomited for around 5 times. I repeatedly burping and finally vomit. I  taken some gas and vomitting injection from hospital. it's gone. Lot of blood test done nothing abnormal shown.  Again 2023 December I vomited like same. This time again no abnormality shown. Finally 2024 july I vomited in same way. Ultrasound taken no abnormality found. This time crp was high around 14.5. Also every time I vomited ketone was positive too. When I checked my blood tests of Last two times I found that my neutrophils was high on both times above 80.  My mother has h pylori infection and I checked that too .hpylori igg antibody was negative. I have not eat anything unusual on those times. This is my problem I dont know when my next vomitting coming. If anyone can help me what's the problem. I have attached my results along with this.
