Hi there. Hyperthyroidism can cause symptoms like increased vocalization and irritability, weight loss, increased appetite, vomiting or diarrhea, and/or increased drinking and urination. It also contributes to high blood pressure, and is hard on the heart and kidneys long-term. If Midnite's thyroid levels are high, treatment would generally be recommended to address this.
