Pain in lower abdomen,diarrhea, dizziness, and nauseous?

These are vague symptoms common to a number of conditions. The simplest may be a simple gut virus, however, without more information and an exam a serious medical condition cannot be excluded. You are welcome to start over and provide more general information.

I agree that the combination of nausea& diarrhea is most often caused by a viral intestinal tract infection. Mild food poisoning or intolerance to something you ingested are other possibilities. All of these resolve on their own after several days. Rest, drink lots of room temperature fluids including flat ginger ale. Eat soft,bland foods as well as broths,saltines at first. Kaopectate as needed.
