During the hot summer days, people all like to drink some beer at the dinner table. Many people think that drinking a few bottles of beer has no harm to their body. In fact, it is very dangerous to drink too much beer. It will make people easily get some diseases.

First, acute gastroenteritis:
Drinking a lot of beer during a short period will dilute the gastric juice and damage the acid environment in the intestines and stomach, so it will reduce the immunity of the digestive tract and make it susceptible to pathogens, thereby causing bacillary dysentery and acute gastroenteritis. At the same time, too much beer will increase the rate of gastrointestinal motility, speed up the excretion of food, which will easily lead to abdominal destension and diarrhea.

Second, alcoholic liver:
Beer itself is very nutritious and can produce a large amount of heat. And most of its nutrients contained can be absorbed by human body. However, as the metabolism of alcohol should be through liver, so if you keep drinking alcohol for a long time, it may lead to alcoholic hepatitis.

Third, cardiovascular disease:
Too much beer will increase blood volume in a short term, and increase the burden on the heart and blood vessels, thus bringing damage to the heart, kidneys, liver, lung and other organs. Sometimes it may cause dizziness, increase the blood pressure, accelerate the heart rate, and may even lead to the attack of cardiovascular disease.

Fourth, calculus:
Beer wort is an essential substance in the brewing of beer. Beer wort not only contains calcium and oxalic acid, but also contains a lot of purine. If you drink too much beer, it will generate excessive heat and increase the production of uric acid, thereby promoting the occurrence of calculus.

Fifth, cold:
Drinking plenty of frozen beer may make you feel very refreshing, but a large number of frozen beer will make the pores shrink because of the sudden cold, so the pores will stop sweating, which will inhibit the heat dissipation of the body, thereby inducing diseases such as cold.

Sixth, aggravate the side effects of the medicines:
If you are taking the following medicines, you should not drink beer. These medicines include antiepileptic drugs, hypoglycemic agents, antidepressants, sedatives, antibiotics, hemostatics and so on, because alcohol will increase the toxicity of these medicines.

Last but not the least, adults should not drink more than 300 ml of beer every time. The best drinking temperature is around 8 degrees Celsius. What's more, when you drink beer, you should not eat the smoked and salted foods.
