Sleepy after eating may be caused by cerebral ischemia and hypoxia, postprandial hypotension, diabetes and other factors.
1. Cerebral ischemia and hypoxia: After eating, digestion and absorption in the gastrointestinal tract requires a lot of blood. At this time, most of the blood is concentrated in the gastrointestinal tract, causing the brain to be prone to mild ischemia and hypoxia, leading to the occurrence of sleepy after eating.
2. Postprandial hypotension: When the elderly are sleepy after eating, they need to consider the possibility of postprandial hypotension. And in postprandial hypotension, there may also be weakness, dizziness and other symptoms.
3. Diabetes: This is a chronic disease that will have a certain impact on the body’s metabolism, and will be prone to lower pancreatic function and reduced insulin secretion. After eating, blood sugar may rise in a short period of time, which may lead to the phenomenon of being sleepy after eating.
Patients who experience drowsiness after eating should go to the hospital in time to clarify the cause and give proper treatment with the help of the doctor.
