What Are the Causes of Disease Occurrence?
The causes of diseases include infectious factors, physical and chemical factors, genetic factors, bodily factors, psychological and social factors, etc. The normal life activities of the body require sufficient nutrients to support; physicochemical factors include high temperature, electric current, strong acids, strong alkalis, etc. Diseases can be prevented by enhancing one's own immunity through medication and improving lifestyle habits.
(1) Infectious factors mainly include pathogenic microorganisms (bacteria, spirochetes, fungi, mycoplasmas, viruses, etc.) and parasites (protozoa, worms, etc.).
(2) Physicochemical factors
Physical pathogenic factors mainly include mechanical trauma, high temperature, electric current and ionizing radiation, air pressure, etc.
Chemical pathogenic factors refer to chemical substances that cause contact damage, such as strong acids and strong alkalis.
(3) Genetic factors
Genetic factors directly cause diseases mainly through chromosome abnormalities and gene mutations.
(4) Bodily factors
1. The normal life activities of the body require sufficient and reasonable nutrients to support.
2. Insufficient iron content in trace elements can cause iron deficiency anemia, while excessive absorption can lead to liver fibrosis.
(5) Psychological and social factors
The accelerated pace of life inevitably produces different psychological effects on the human body, affecting the internal stability of the body.
1. Diseases can be prevented through medication, such as vaccination.
2. Improve lifestyle habits such as getting up early and going to bed early, quitting smoking and drinking, ensuring adequate sleep and balanced diet, drinking plenty of water, etc.
