I have had loose stool for 1 week now. But it doesn't have a smell AT ALL. I have not been sick with any illness and no stomach cramps. This just star?

Watch and wait. If just loose stool without fever, nausea, vomiting, belly pain then stay well hydrated and watch it for now. Can add Gatorade for some electrolytes. Possibly a reaction to a new med, new food, etc.. watch it for now and if worsens talk to your doctor. .
