What is the difference between low blood pressure and low blood sugar? What are the symptoms?

Hypotension means that the patient's blood pressure suddenly drops significantly from normal or high level. Clinically, dizziness, dark eyes, weakness of limbs, cold sweat, palpitation, oliguria and other symptoms often occur due to ischemia of important organs such as brain, heart and kidney, and severe cases are syncope or shock. Mild symptoms of hypoglycemia include dizziness, headache, loss of appetite, fatigue, pallor, indigestion, motion sickness and so on. Severe symptoms include: upright vertigo, chills in limbs, palpitation, dyspnea, ataxia, slurred speech and even fainting. Hypotension means that the systolic blood pressure (commonly known as high pressure) of arterial blood pressure is lower than 12 kPa (90 mm Hg) and the diastolic blood pressure (commonly known as low pressure) is lower than 8 kPa (60 mm Hg). Normal blood pressure in adults is lower than 90/60mmhg, and that in the elderly is lower than 100/70mmhg, which is also called hypotension. Hypotension can be divided into acute and chronic. The hypotension we usually discuss is mostly chronic hypotension, that is, long-term hypotension, accompanied by dizziness, dizziness, fatigue and other symptoms. According to statistics, the incidence of hypotension is about 4%, which can reach 10% in the elderly population. Hypoglycemia is the opposite of diabetes: the body secretes more insulin than it needs, which causes insulin to take glucose out of the blood excessively and cannot leave enough glucose to provide vitality. Patients with hypotension should choose a diet with high sodium (salt should be 12- 15g per day) and high cholesterol, such as animal brain, liver, egg yolk, cream, roe, etc. Thereby increasing blood volume, cardiac output, arterial tension and blood pressure. The low blood pressure diet should be: a combination of meat and vegetables. Longan, lotus seed, jujube, mulberry, etc. , has the effect of strengthening the heart and brain, and should be eaten regularly to enhance physical fitness; For hypotension caused by blood loss and menorrhagia, we should pay attention to eating foods that provide hematopoietic raw materials, such as foods rich in protein, copper and iron-liver, fish, milk, eggs, beans and vegetables and fruits with high iron content, which will help correct anemia. Avoid cold food, such as spinach, radish, celery, cold drinks, etc. Patients with hypoglycemia should not eat antihypertensive foods such as corn. Diet should be high in sugar, protein and fat, eat less and eat more meals, and drink sugar at midnight if necessary.

Hypotension can generally be divided into three categories: ① Constitutional hypotension, which is generally considered to be related to heredity and emaciation, and is more common in women and the elderly aged 20-50. Mild people have no symptoms, and severe people have mental fatigue, dizziness, headache and even fainting. It is more obvious when the temperature is higher in summer. ② Postural hypotension: Postural hypotension refers to the sudden drop of blood pressure by more than 20mmHg when a patient changes from a lying position to a sitting position or an upright position, or when standing for a long time, accompanied by obvious symptoms, including dizziness, blurred vision, fatigue, nausea, cognitive dysfunction, palpitation and neck and back pain. Postural hypotension is related to many diseases, such as multiple system atrophy, diabetes, Parkinson's disease, multiple sclerosis, menopausal disorder, hemodialysis, postoperative sequelae, anesthesia, antihypertensive drugs, diuretics, sleeping pills, antidepressants and so on. Or other elderly people who have been bedridden for a long time and have weak constitution. ③ Secondary hypotension: hypotension caused by certain diseases or drugs, such as syringomyelia, rheumatic heart disease, antihypertensive drugs, antidepressants, chronic malnutrition and hemodialysis patients.

There are many reasons for hypoglycemia. Generally speaking, there are several reasons for hypoglycemia: First, blood sugar is reduced because of insufficient sugar intake or poor digestion and absorption function. Second, liver diseases or lack of enzymes for sugar metabolism make the storage and utilization of sugar insufficient.

Third, the hormones that raise blood sugar decrease, such as growth hormone, cortisol, glucagon, adrenaline and so on.

Fourth, there are too many hormones and substances that lower blood sugar, such as insulin.

Fifth, the body consumes too much sugar. Generally speaking, the causes of hypoglycemia are mainly divided into two categories: insufficient sources and excessive consumption.
