My daughter is 18, 5"9" around 190lbs and has had only one medical issue that the doctor in the ER told her was a kidney stone, that was about a year ago. She just told me she has headaches every other day, nausea when she eats, gets dizzy later in the day and blood in the toilet with her bowel movements. This has been happening for the past two weeks.
Hi, Kidney stones can cause nausea and even severe vomiting. You can take Risperidone for symptomatic relief. The blood in the stool is not related to kidney stones, and it may be due to something else. You can consult a general surgeon and he evaluated. Hope I have answered your query. Let me know if I can assist you further.
