It’s the season when lychees are on the market again. They are sold in both large supermarkets and roadside fruit stalls. The price is not very expensive, only five yuan per pound. I like eating lychees very much. I always buy some and go home every few days. I usually don’t keep my lychees overnight. I turn on the TV at home and eat them while watching them. I can eat one or two kilograms at a time and I can’t stop at all. But recently I saw on Weibo that someone suddenly fainted after eating more than 20 lychees. It felt a bit scary. So why do people faint after eating too many lychees?

1. Fainted after eating more than 20 lychees

The 7-year-old Junzi came home from school a few days ago, hungry and thirsty, and happened to see a basket of fresh lychees on the dining table. , I started eating no matter what, and ate more than 20 pills in one go. Looking at the lychee peels and cores lying on the ground, Junzai burped with satisfaction and went to do his homework.

At dinner that day, Junzai suddenly started sweating on his forehead and turned pale. He fainted at the dinner table after taking two mouthfuls of food. The family quickly sent Junzai to the hospital, where he was diagnosed with hypoglycemia.

Recently, it is the season when Lingnan Jiaguo lychees are on the market in large quantities. The reporter learned from the hospital that there are patients with "lychee disease" every summer. Among them, there are cases of hypoglycemia and even syncope after eating a large amount of lychees. Not uncommon.

Li Xiangli, deputy chief physician of the Department of Traditional Chinese Medicine of Guangzhou First People's Hospital, reminded that lychees are delicious but should not be eaten in excess. Excessive eating can cause hypoglycemia, and citizens should pay attention.

2. Why do you feel dizzy if you eat too much?

Whenever lychees are on the market, many neighbors say that after eating too many lychees, they will suffer from "heat" symptoms, such as throat inflammation and dry mouth. Dry tongue, swollen and painful gums, etc. There are also reports on the Internet that children develop fever, convulsions, and coma after eating a large amount of lychees.

Lychees are obviously so sweet, so why does eating too much cause hypoglycemia? What is going on?

Experts explain that "heat" and "lychee disease" are both caused by the fructose in lychees. The sweetness in lychees is provided by a large amount of fructose, and fructose must be converted by the invertase in the liver. In order for glucose to be absorbed and utilized by the body.

Therefore, if you eat a large amount of lychees in a short period of time, a large amount of fructose will accumulate in the blood vessels, resulting in a state of "in short supply" of invertase, which will not be able to convert fructose into glucose in time. At the same time, fructose will also stimulate the body to secrete a large amount of insulin, causing the liver to lower blood sugar concentration, resulting in insufficient glucose supply in the blood.

In addition, consuming a large amount of lychees during meals can easily make you feel full, thereby reducing the intake of other foods, further reducing glucose supply, causing symptoms of hypoglycemia, and even hypoglycemic encephalopathy. Nausea, sweating, fatigue, and then causing high fever, convulsions, coma and other symptoms.

3. Precautions for eating lychees

1. Not suitable for eating on an empty stomach

Fresh lychees have a high sugar content. Eating them on an empty stomach will irritate the gastric mucosa. Stomach pain and bloating may occur. Moreover, eating too much on an empty stomach can cause "hyperosmolar coma" due to the sudden addition of excessive amounts of sugar to the body.

2. Try not to eat lychees soaked in water

Many lychees on the market are soaked in water and contain a lot of water. When a large amount of water enters the gastrointestinal tract, it will dilute the digestive juices, cause loss of appetite or indigestion, and also cause temporary hypoglycemia.

Some blister lychees may contain toxic ingredients such as detergents, which may also cause dizziness.

3. It is not advisable to eat a large amount of lychees

Eating a large amount of lychees and eating very little can easily cause sudden hypoglycemia, dizziness, thirst, nausea, sweating, and stomachache. , palpitation and other phenomena. In severe cases, coma, convulsions, arrhythmia, etc. may occur. These symptoms are caused by sudden hypoglycemia after eating a large amount of lychees. Medically, they are called acute lychee poisoning, also known as "lychee disease." Because most of the monosaccharides contained in lychees are fructose, after being absorbed by the body, fructose must be catalyzed by a series of enzymes before it can be converted into glucose for energy or converted into glycogen for storage, and can be oxidized and utilized by tissue cells.

If you eat too many lychees at one time, the blood sugar level will be much lower than normal and cause hypoglycemia. Therefore, litchi disease is an acute disease caused by hypoglycemia. It manifests itself early in the morning, often with early symptoms such as sweating, cold limbs, fatigue, and diarrhea, followed by sudden convulsions and coma. If you have symptoms of internal heat, you can eat some watermelon, which is cold in nature, to relieve the fever.

Or drink 20 to 30 grams of raw ground lean meat or pork bone soup, which can effectively prevent litchi disease.

6. Lychees growing in the east canopy

It's sweet, but it will be more spicy. Therefore, if you are afraid of getting angry, you can choose lychees growing on the branches on the east side, which are relatively mild.
