Core Tip

Core tip: Depressive and anxiety disorders are common psychiatric illnesses. Depression and anxiety can not only lower the quality of life but also affect the therapeutic effects on somatic diseases. Research has shown that detection rates of depression and anxiety symptoms are high in patients with chronic digestive system diseases, especially in patients with digestive system tumors, liver cirrhosis, functional dyspepsia, and chronic viral hepatitis. Elderly patients, divorced/widowed patients, patients with a low degree of education, limited daily activities, poor sleep quality, or a lower body mass index are at higher risk for depression and anxiety symptoms.
