There are many reasons for sudden death after drinking, such as nausea and vomiting after drinking, which can lead to sudden death when a foreign body enters the trachea by mistake. However, when the vomit enters the airway, it will lead to violent coughing, breathing will be affected, pupils will be dilated, body temperature will be lowered, breathing will be slow, heart rate will be accelerated, which belongs to the sudden death caused by drinking alcohol by accidental inhalation. There is also the possibility of sudden cardiac death after drinking alcohol, because drinking alcohol has a certain stimulating effect on the cardiovascular system, or causes the heart muscle to be in a high state of stress, and the patient will experience sudden cardiac death, which may be preceded by chest tightness, chest pain, or some other symptoms, such as dizziness and lack of energy before sudden death. Some patients with sudden death do not have any symptoms and fall into a state of respiratory and cardiac arrest.
