According to 39 Health Network, under normal circumstances, the top ten chronic diseases can be treated as disability certificates, but disability certificates need to be considered comprehensively according to specific conditions. Chronic diseases generally refer to diseases with slow onset, long course and prolonged course, such as diabetes, hypertension, coronary heart disease, chronic bronchitis, chronic obstructive pulmonary disease and chronic glomerulonephritis. If the patient has the above-mentioned chronic diseases, he can generally apply for a disability certificate. However, when handling the disability certificate, it is necessary to choose the appropriate certificate according to the patient's own situation and under the guidance of a professional doctor. In daily life, patients are advised to pay attention to a healthy diet and try to eat light food. It is not recommended to eat foods with high fat content or high sugar content, otherwise the blood sugar concentration in the body will increase, thus increasing the incidence of diseases such as diabetes. In addition, patients should also go to the hospital for regular review and pay attention to the recovery of the body in time.
