The blood glucose concentration of normal people is generally between 80-120mg% . When the blood sugar is lower than 55mg% , a series of symptoms will occur, which is called hypoglycemia. The disease mostly occurs during or after the races of long-distance running, ultra-long-distance running, cycling, long-distance, ice-skating and skiing.
(I) Cause
Hypoglycemia during or after exercise is mainly caused by heavy consumption and reduction of blood glucose during prolonged strenuous exercise, or due to pre-exercise hunger, insufficient reserve of hepatic glycogen in the body, and inability to supplement blood glucose in time; Central nervous system regulates sugar Metabolic dysfunction, increased insulin secretion (insulin has a role in lowering blood glucose); poor training level, nervous before the game, or illness to participate in training, competitions, etc., are all important causes of hypoglycemia during exercise.
(b) Signs
In the light, the athletes felt obvious hunger, fatigue, dizziness, palpitations, pale, and cold sweats. Those who are heavier may suffer from confusion, confusion, insanity (such as runners running back), trembling limbs, irritability, convulsions, and even coma. At the time of examination, the pulse was rapid and weak, breathing was short, and the pupils were enlarged. Blood glucose was reduced to less than 55 mg% .
(III) Processing
Let the wounded person lie flat, keep warm, clear mind can be printed with sugar water and give a small amount of food, usually after a short time the symptoms can disappear. If the patient is in a coma, he or she can be instructed in acupuncture points and intravenously inject 50% glucose 50-100ml to raise the blood glucose concentration and the condition can be seen to improve rapidly.
(d) Prevention
Usually lack of exercise, or fasting hunger, or illness is not healed, do not participate in prolonged strenuous activities. Trainers participate in long-term strenuous sports competitions, such as 1,000- meter runs, long-distance bicycles, marathons, etc., and there should be supplies of sugary drinks on the way.
