External factors include: living environment and climate conditions, such as sunlight, heat, dryness, animal fur, dander, pollen, dust mites, wool, etc. In terms of diet, common high-protein foods include fish, shrimp, eggs, milk, beef and mutton, etc., spicy and stimulating foods, and various food additives. Various chemical substances such as cosmetics, soap, synthetic fibers, etc.
Internal factors include: chronic infection foci, chronic cholecystitis, tonsillitis, intestinal parasites; blood circulation disorders commonly seen include varicose veins in the lower legs that induce leg eczema; neuro-psychological factors such as mental tension, insomnia, excessive fatigue, etc.; endocrine disorders and metabolic abnormalities, such as menstrual cycle, pregnancy factors, have a close relationship with the occurrence of this disease, such as excessive mental tension and excessive fatigue; individual constitution is also very important. An individual's susceptibility or tolerance to various factors can be enhanced or weakened by physiological or pathophysiological effects.
