The reason why hypertensive patients try not to eat late night is the following: 1, eating late night may increase the burden on the gastrointestinal tract, so that the gastrointestinal tract can not get enough rest, which in the long run will seriously lead to gastrointestinal diseases, such as chronic gastritis, gastric ulcer, etc. 2, often eat late night may affect the quality of sleep of patients, poor sleep will lead to poor mental state of patients, causing blood pressure to rise, which has a certain impact on maintaining the blood pressure. 3, often eat late night will increase the calorie intake, may lead to patients with abnormal blood lipids, blood sugar, triggering hyperlipidemia, diabetes, etc.. Therefore, it is recommended that patients with hypertension should not eat snacks as often as possible, but once in a while it does not matter, they should try to keep their diet light, do not eat spicy, greasy food, and should take their medication on time to ensure the stability of blood pressure.
