1. This information is very important for evaluating children's health status and preventing possible health problems in the future. For example, if your child has ever suffered from a serious illness, you may need to be especially careful when vaccinating or performing certain medical procedures. Similarly, if children are allergic to certain substances, they also need to avoid contact in their daily lives.
2. Chief complaint: the main symptoms and duration of the patient. Current medical history: including the beginning, development and change process of the disease, as well as the treatment and treatment effect received by the patient. Past medical history: including the patient's past diseases, operations, allergic reactions, etc. Family history: including the health status of the patient's parents, siblings, children and other relatives, especially whether there are genetic diseases or chronic diseases.
The related knowledge of heredity is as follows:
1. Inheritance refers to the process in which an organism transmits its genes to its offspring. In humans, heredity is a combination of parents' genes. Human genes are composed of DNA molecules, and each DNA molecule contains thousands of genes, which determine our appearance, physiological characteristics and health status. Hereditary diseases are diseases caused by abnormal genes.
2. These abnormal genes may be inherited by parents, or they may be mutations during embryonic development. Genetic diseases can be monogenic or polygenic. Monogenic genetic diseases are caused by monogenic mutations, such as cystic fibrosis and sickle cell anemia.
3. Polygenic genetic diseases are caused by the interaction of multiple genes, such as diabetes and hypertension. The occurrence of genetic diseases is closely related to genetic factors. If there are genetic diseases in a family, the risk of their children suffering from the same disease will increase. This is because they inherited the same abnormal gene.
However, even if both parents are healthy, their children may suffer from genetic diseases, because some genetic diseases are caused by recessive genes and can only be transmitted between two carriers. In addition to genetic factors, environmental factors will also affect the occurrence and development of diseases. For example, unhealthy lifestyles such as smoking and bad eating habits will increase the risk of certain diseases.
