Patients are particularly sleepy after eating, mainly consider the following reasons: 1. It may be caused by the excessive amount of food eaten by the patient, resulting in a relatively heavy burden on the gastrointestinal tract. Because the gastrointestinal tract needs to digest food in this case, the blood of the body will be redistributed, and the blood flowing to the gastrointestinal tract is more, and the blood volume of the whole body is limited, which will lead to a relative decrease of blood flowing to the heart and brain. If the patient has previous problems such as sclerosis of the cerebral arteries and cerebral vascular stenosis, it will easily lead to the patient’s symptoms of special sleepiness. 2, the patient is particularly sleepy after eating, to consider may be related to the type of diet. If the patient’s blood is in a high-fat, high-viscosity state, and then eat some greasy, poorly digested food, it is easy to cause the patient’s blood more viscous and cause cerebral blood supply deficiency, the patient will also have a special sleepy, weak performance, and in serious cases, even dizziness.
