① Increased catecholamines lead to elevated blood pressure; ② Decreased catecholamines result in lowered blood pressure or even shock; ③ Increased peripheral resistance leads to heart disease or even heart failure; ④ Increased catecholamines cause constriction of gastrointestinal blood vessels, resulting in nausea, vomiting, abdominal distension, constipation, and potentially intestinal bleeding or perforation; ⑤ Increased catecholamines generate heat, causing fever and headache; ⑥ Increased catecholamines inhibit insulin secretion, leading to glycosuria; ⑦ Increased catecholamines promote thyroid hormone secretion; ⑧ Increased catecholamines promote adrenal cortical hormone secretion; ⑨ The most effective treatment is surgery, though surgery carries certain risks that warrant attention.
