For individuals with coronary heart disease or angina, walking after a meal can easily induce angina, and even lead to a myocardial infarction. This is because after eating, the blood in the body becomes more prone to clotting, which can easily lead to thrombosis and myocardial infarction.
For people with hypertension, cerebral arteriosclerosis, and diabetes, walking after a meal can easily lead to orthostatic hypotension, resulting in symptoms such as dizziness, fatigue, and even fainting.
For individuals with gastroptosis, walking after a meal can easily cause abdominal bloating and discomfort, and may even lead to nausea and vomiting.
For those with anemia or hypotension, walking after a meal can cause cerebral ischemia due to a large amount of blood being supplied to the stomach, leading to dizziness, vertigo, and even fainting. Patients with the aforementioned conditions, as well as the elderly and frail, should not walk immediately after a meal. Instead, they should first massage their abdomen and rest for half an hour before walking, which is more beneficial to their health.
