If you feel irritable all the time, you need to exclude hyperthyroidism as a disease. Patients with hyperthyroidism can have obvious temper and emotional abnormalities, and patients are very hot-tempered and easily irritable. Therefore, it is recommended that patients who are easily irritable can visit the endocrinology department to at least improve thyroid function tests to clarify whether hyperthyroidism exists. If this disease does not exist, you can go to the psychology department to clarify whether the psychological disease is the cause of the particular irritability. If it is not the cause of psychology or endocrinology, it needs to be further investigated in neurology or other departments.
