Hi,
Welcome to health care magic,
This type of loose motions or acute diarrhea could be infective (virus,bacteria, parasite) or dysentery or
lactose intolerance or
irritable bowel syndrome or due to some allergy etc.
I do not think that eating lots of salads can cause severe outbreaks of loose motions,the reason could be some thing else as i said above.
So,you should go for routine blood count,electrolytes and stool examination with
ultrasound abdomen.
Generally, this diarrhea are self limiting and requires no definitive treatment but in case they persists longer then one may need to find out the actual cause.
Treatment is mainly depend on the underlying cause but you may require antibiotics (ofloxacin with
metronidazole) if infective,
prebiotics and probiotics,antispasmodics, antacids,anti-inflammatories etc.
You should consult your family physician for further advise immediately and take complete treatment.
Regards,
