Beware of stroke, heart disease and digestive tract ulcer in heavy snow and solar terms.

Tomorrow is 20 17 12.7, and the annual solar term of heavy snow is coming. After that, the minimum temperature in most parts of China will drop to 0℃ or below. In the increasingly cold weather, you need to be careful to guard against some common winter diseases, such as stroke, heart disease and digestive tract ulcer, so let me bring you the advice of health experts.

Prevention of stroke

For people with poor vascular elasticity, the sudden change of temperature will bring about blood pressure fluctuation and trigger a stroke. Cold will excite people's sympathetic nerves, increase catecholamine in blood, and lead to systemic vasoconstriction. At the same time, when the temperature is low, the perspiration decreases and the blood volume increases relatively, which can increase blood pressure and promote cerebral hemorrhage.

Heart disease prevention

Winter and late winter and early spring are two high incidence periods of acute myocardial infarction. In addition, the diseased coronary artery is particularly sensitive to cold stimulation, which contracts and even occludes blood vessels, leading to myocardial ischemia and hypoxia, angina pectoris and even myocardial infarction.

Therefore, the elderly should pay attention to cold and warmth, add clothes and bedding at any time according to the weather changes, and conduct regular physical examination of the cardiovascular system to prevent the invasion of cold. Under the guidance of a doctor, drugs for thrombolysis, lipid lowering, vasodilation and myocardial ischemia and hypoxia should be selected.

Prevention of digestive tract ulcer

At this time, due to the increased excitability of the human nervous system stimulated by cold, the autonomic nerves that dominate the internal organs are in a state of tension. Under the reflex action of parasympathetic nerve, gastrointestinal lymph nodes are dysfunctional, and gastric acid secretion increases, which in turn stimulates gastric mucosa or ulcer surface, causing spasmodic contraction of the stomach, causing ischemia and hypoxia of the stomach itself, thus causing recurrence of gastric diseases. Therefore, we should pay attention to the warmth of the stomach and diet.
