The main factors that make psychiatric patients prone to accompanying somatic diseases are as follows: 1. Age factor: psychiatric patients over 40~50 years old are prone to accompanying a variety of somatic diseases, and the older the patient is, the more serious the deterioration of the function of various organs; 2. Self-care ability: chronic psychiatric patients with a decline in the ability to take care of themselves are not able to express the existing somatic discomfort, and are unable to correctly identify the physical condition of the body is good or not; 3, Lifestyle: patients have unhealthy lifestyles, such as smoking, alcoholism, irregular diet (overeating or anorexia), lack of exercise, lack of attention to personal hygiene, etc.; 4. Side effects of antipsychotic drugs: the long-term effects on the body’s blood lipids, blood glucose, and physical fitness; 5. Prejudice and discrimination in the society: patients do not receive more care and attention, and they have no time to pay attention to the patients’ physical health; 6. Knowledge of the disease: patients’ family members do not have the knowledge to express existing physical discomforts, and they cannot correctly recognize whether their physical condition is good or not; 6. Disease knowledge: the patient’s family members do not have adequate knowledge of somatic diseases and cannot judge the occurrence and development of somatic diseases in time.
