Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting and diarrhea can occur secondary to conditions such as inflammatory bowel disease, dietary indiscretion, parasites, among other possibilities. This could certainly be due to her hyperthyroidism or even due to the medications that she is currently on for it. I recommend that you have Gabriella evaluated by your veterinarian for further assessment and treatment. At the very least they can start her on medications to make her feel better and check her hydration status. In the meantime, keep water available at all times to try to prevent dehydration. Good luck and have a good day!
