Eat clean, fruits and vegetables in moderation Fresh fruits and vegetables are coming on the market in summer, many elderly people do not have an appetite, always like to replace the staple food with fruits and vegetables, if not clean or do not pay attention to control the number, often to meet the mouth and hurt the body, causing acute gastroenteritis and cause diarrhea, appetite loss, gastrointestinal discomfort. At the same time, we should pay attention to increase the amount of water, especially to pay attention to timely replenishment of water and sodium, potassium and other electrolytes, drinking water to a small number of times is better. How much to eat and how much to do The weather is getting hot, some elderly people do a lot of meals, but once and can not finish, often happen to do a meal to eat a few meals of the phenomenon. But in the summer food is placed too long, it is easy to spoil, even in the refrigerator, but also because the food is not heated through and lead to food poisoning or induce gastrointestinal diseases. The elderly have weakened spleen and stomach function, digestion and absorption ability is reduced, summer heat and humidity heat evil easily attack the spleen and stomach, affect the spleen and stomach digestion and absorption function, such as eating cold food, drinking cold drinks, will damage the spleen and stomach. Although all kinds of cold drinks can relieve heat, but the digestive tract mucosa will produce adverse stimulation, can slow down the gastrointestinal circulation, gastrointestinal peristaltic disorder, and even spasm phenomenon, causing severe abdominal pain. Therefore, the elderly should drink less cold drinks and eat less cold food. The elderly with digestive tract diseases should pay particular attention. The summer heat can be eliminated by drinking not too strong hot tea and green bean soup. Less blowing air conditioning, do not go out at noon Experts remind, the elderly preferably do not adjust the air conditioning temperature too low or stay in the air conditioning room for a long time, in order to prevent the temperature difference between the room in and out of a large induced cardiovascular disease. If you use air conditioning, the temperature difference between indoor and outdoor should not exceed 5-7 ℃; in hot and muggy weather, outdoor activities should be reduced, and should not participate in strenuous exercise. To ensure adequate rest and sleep, it is best to have 1-2 hours of naps every day. Strengthen your sense of protection and carry with you when you go out, such as Manjin Oil, Ren Ren Dan and other anti-stroke medications, just in case. Diarrhea must be taken seriously Diarrhea is more damaging to the body of the elderly, because acute diarrhea in the elderly is prone to electrolyte disorders, hypoglycemia, blood volume deficiency, inducing or complicating heart and cerebrovascular diseases and other unexpected complications. The large amount of water lost during diarrhea in the elderly can put the body in a dehydrated state, resulting in reduced blood volume, increased blood viscosity and slow blood flow, which can easily form blood clots and block blood vessels. Sodium, chloride, potassium, calcium, magnesium and other elements that maintain the acid-base balance of the blood, nerve conduction function and heartbeat rhythm, the lack and loss of these elements caused by diarrhea may cause serious heart rhythm disorders, which is particularly detrimental to elderly people suffering from cardiovascular diseases. When diarrhea generally decreases appetite, the elderly are prone to a series of hypoglycemic symptoms such as weakness, sweating, palpitations, pallor and fainting. Therefore, once diarrhea occurs in the elderly, do not take it lightly, should promptly seek medical attention.
