In early summer, diarrhea patients increased steeply, especially children due to diarrhea and the high proportion of hospital visits. Why diarrhea in early summer? The reasons are manifold. In early summer, the trend of temperature is rising, but the temperature also fluctuates, the weather is unpredictable. At this time, the body’s physiological heat dissipation and warmth function and winter and early spring has been very different. Winter or early spring, the human body by the strong stimulation of low temperature, the skin surface of the sweat gland pores will be closed to resist the cold and save the body heat, which is the Chinese medicine on the “cold inside the cold”. In early summer, with the temperature of a substantial rise, the human sweat glands have been “open” to meet the summer. If there is a “May cold” weather, the sudden arrival of the cold is most likely to invade the body, the body’s systems, organs of the physiological coordination of a moment to adapt to, resulting in functional disorders, dysfunction, resistance to reduce not only the cold and flu should be born, but also lead to a number of “old disease “recurrence or aggravation, including some symptoms of diarrhea for the digestive system diseases. In addition, early summer air humidity is greater, bacteria are easy to survive and reproduce, which is also easy to infect one of the causes of diarrhea. So people with a history of chronic gastrointestinal disease, when the climate of the early summer, we must pay attention to warmth, timely increase or decrease in clothing; in the aftermath of strenuous exercise, we must change underwear in a timely manner to prevent cold, endangering the intestinal tract; children should pay more attention to the prevention of colds and flu, to avoid catching diarrhea. Why are children prone to diarrhea in early summer? This is determined by the physiological characteristics of pediatrics and dietary characteristics. On the one hand, the intestinal tract of the children’s stomach is not yet mature, less gastric acid, sterilization ability is poor, on the other hand, the weather is a little hot, ice cream, ice cream, these cold foods have become the children’s favorite things to eat, if the early summer too much cold drinks, dilute the gastric acid, resulting in germs are easy to break through the gastric acid this pass, enter the intestinal tract smoothly, thus causing diarrhea. In addition, children (especially infants and young children) grow rapidly, the need to supplement adequate nutrition in a timely manner, resulting in a relatively heavy burden on the gastrointestinal tract of children, easy to digestive disorders, thereby increasing the chances of diarrhea infection. Early summer temperature is high, food is easy to deteriorate, and the child’s ability to identify whether the food is spoiled is weak, which is also easy for children to develop toxic diarrhea. Therefore, in early summer, parents should pay attention to controlling their children’s intake of cold drinks, to ensure that their children eat healthy food, but also should not allow their children to overeat, including excessive intake of breast milk; to cultivate children’s good hygiene habits, wash their hands before eating and after eating, and do not eat spoiled food. How to deal with diarrhea in children? The onset of diarrhea can be slow or acute, mild or severe. In mild cases, there is only loss of appetite, increase in stool frequency and change in its character, occasional vomiting, and generally good general condition with few symptoms of dehydration. At this time, in addition to the first time to avoid sensitive and unclean food, should temporarily eliminate all alkaline fruits, such as bananas, pears, watermelon, etc., increase some brown food, such as corn, peanuts, soybeans, etc., and timely replenishment of water to accelerate blood circulation, as soon as possible to discharge harmful substances, often without medication, and also can be cured soon. If the daily stool more than 10 times, often accompanied by fever, vomiting, at this time it is necessary to go to the hospital, so as not to delay the condition. Here to remind parents, children suffering from diarrhea, do not use antidiarrheal drugs too early. This is because there are many causes of diarrhea, the abuse of antidiarrheal drugs, on the contrary, will mask the symptoms, aggravate the condition, such as bacterial infections, taking antidiarrheal drugs, bacteria, toxins and other metabolites can not be discharged from the body, absorbed into the bloodstream, which appeared in the systemic infection symptoms of toxicity, resulting in aggravation of the condition.
