Sleepiness after eating is related to the patient’s physical condition, and there may be a thickening of the blood. In addition, the stomach needs to digest and absorb the food after eating, so the gastric power will increase, and the blood supply to the stomach will also increase, so the blood flow to the brain will naturally decrease, and the blood supply to the heart will also decrease, so the symptoms of sleepiness after eating will be manifested. This explains why many patients with heart disease and cerebrovascular disease are prone to acute heart problems after eating too much, which is the reason. This symptom must be checked by the hospital for blood tests, including blood lipids, blood sugar and blood rheology, and a meal should be eaten in small portions, only 8 minutes full.
