The weather is hot and dizzy, and the culprit is not necessarily "high temperature", but may be targeted at six diseases.

Summer is coming, and it is very hot every day. Many people have symptoms of dizziness. Many people think it's heatstroke. In fact, dizziness is a symptom and may be related to many diseases. So what is the heat and dizziness? Dizziness may be related to many diseases.

Vertigo can be divided into true vertigo and false vertigo. True vertigo is mainly induced by cerebrovascular diseases, while false vertigo may be induced by anemia, hypoglycemia and other reasons. The patient was described as "dizzy". If it is induced by cerebrovascular disease, it may be life-threatening if it is not taken seriously. So what is the heat and dizziness? May be caused by the following diseases:

1, hypotension, hypoglycemia

Why is the blood pressure low when the weather is hot? On the one hand, the weather becomes hot, sweating increases, and volatile water on the body surface increases, which plays a certain role of "diuresis" and makes the human body lose a certain liquid capacity. On the other hand, the external temperature rises, the blood vessels on human body surface dilate, and the volume of vascular bed increases, which further leads to the relative shortage of liquid in human body. The superposition of these two factors leads to the decrease of blood pressure and even hypotension.

How can we avoid this situation? In fact, it is good to monitor blood pressure regularly. Dizziness caused by hypoglycemia is more common in diabetic patients, and normal people generally do not have hypoglycemia.

2. It may be heatstroke.

If you have chest tightness, dizziness, nausea, vomiting and other symptoms in a high temperature environment, be careful. These are the precursors of heatstroke. There are three kinds of heatstroke: heat spasm, heat exhaustion and heatstroke. In high temperature environment, once people have symptoms of heatstroke such as sweating, thirst, fatigue, dizziness, dizziness, tinnitus, nausea, palpitation and inattention, they can apply cool oil and wind oil essence. Stick it on your forehead, or take drugs such as Ren Dan, ten drops of water and Huoxiang Zhengqi water.

3. Cervical spondylosis

Cervical spondylosis can also cause dizziness. The dizziness caused by cervical spondylosis has an obvious feature, which is obviously related to the change of posture. Patients usually feel dizzy or even faint when they suddenly turn around. Vertebral artery type cervical spondylosis accounts for about 10%~20% of cervical spondylosis, and the patients are generally over 50 years old. If they are ill, they must be treated in time. It is very dangerous if they faint while riding their bikes at the traffic lights. Whether there is vertigo caused by cervical spondylosis can be diagnosed by magnetic vibration or angiography, and where stenosis and compression can be basically diagnosed.

4. Watch out for anemia

In summer, many women eat less food or only vegetarian food in order to keep fit, and their basal metabolic rate is much lower than that of ordinary people. Therefore, slow gastrointestinal movement and low gastric acid secretion will affect the absorption of nutrients, and women are prone to anemia symptoms such as dizziness and fatigue during menstrual period. Vegetarians only eat spinach and don't eat meat, which is prone to iron deficiency anemia. Get more iron from daily food. Foods with high iron content include celery, sesame, spinach, black fungus, soybean, tofu, pig liver, chicken liver, fish and so on. Choose an iron pot for cooking. If it is anemia caused by poor absorption of iron in the stomach, it is necessary to treat gastrointestinal diseases first.

5. Beware of "cerebral infarction"

When the hottest summer comes, people sweat more and lose more water, especially the elderly, less than the young. In addition, the physiological reaction is relatively slow, leading to blood concentration or even "dehydration", leading to increased blood viscosity and stroke. In summer, we should do moderate physical activities, such as walking and jogging, treat patients with diabetes, coronary heart disease and liver and renal insufficiency in time, control blood pressure at a normal level, and pay attention to smoking and alcohol control.

6, be careful of air conditioning disease

It is understood that air-conditioning diseases are mainly manifested as dizziness, fever, dry eyes, joint pain, muscle pain and other symptoms. There are many reasons for air-conditioning diseases, the most important of which is that the indoor temperature is too low in summer, and blowing air conditioners for a long time will make the cold stagnate in the body.

In addition to these diseases mentioned above, poor rest, sudden increase in exercise, excessive use of eyes, taking anti-cold drugs, etc. may all induce dizziness. Generally, dizziness will be relieved after rest!
