How many episodes of loose motions have you had? Is it watery, semisolid, or normal consistency? Any associated blood with stools? What about the quantity of stools? small amount or large copious amount?
Based on what you have told me, you could have gastro-enteritis
, maybe caused by the food you have eaten. I would advise you to go to a doctor, and get yourself examined so that the doctor can prescribe you medications for the nausea
Meanwhile, take loads of fluids-water, juice, milk etc. The idea is to replenish the fluid losses occurring through the stools. So drink as much as you can. You could even take the Oral Rehydration Solution-''ORS'' available in your area (which has been designed to replenish the losses). It is important to mix the ORS in exact amount of water as mentioned on the pack and drink it as often as you can. (as incorrect preparation can worsen the loose stools)
Consult a doctor as soon as possible. If the loose stools become more severe, if you develop fever/pain/vomiting/dizziness-go to the emergency room immediately.
