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

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

dizziness can be divided into true vertigo and false vertigo. True vertigo is mainly caused by cerebrovascular disease, while false vertigo may be caused by anemia, hypoglycemia and other reasons. The patient is described as "head 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? It may be caused by the following diseases:

1. Hypotension and hypoglycemia < P > Why is blood pressure low when the weather gets hot? On the one hand, the weather becomes hot, sweating increases, and the volatile water on the body surface increases, which plays a certain role of "diuresis" and causes the loss of a certain liquid capacity of the human body. 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, and the combination of these two factors leads to the decrease of blood pressure and even hypotension.

how can we avoid this situation? In fact, just monitor your 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, you should be careful. These are the precursors of heatstroke. Heatstroke can be divided into three types: heat spasm, heat exhaustion and heatstroke. In the high temperature environment, once people have symptoms of heatstroke, such as sweating, thirst, weakness, dizziness, dizziness, tinnitus, nausea, palpitation and inattention, they can apply cool oil, wind oil, etc. on their foreheads, or take drugs such as Rendan, 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 generally feel dizzy or even faint when they suddenly turn around. Vertebral artery type cervical spondylosis accounts for about 1%~2% of cervical spondylosis. Patients are generally over 5 years old. If they are sick, they must be treated in time. If they faint while riding a bicycle at a traffic light, it is very dangerous. Whether there is vertigo caused by cervical spondylosis can be diagnosed by magnetic vibration or angiography, and which place is narrow and squeezed can basically be diagnosed.

4. Watch out for anemia

In order to keep in shape, many women eat less food or only eat vegetarian food in summer, and their basal metabolic rate is much lower than that of ordinary people. Therefore, slow gastrointestinal movement and less gastric acid secretion will affect the absorption of nutrients, and women are prone to dizziness, fatigue and other anemia symptoms. 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, auricularia auricula, soybean, tofu, pork liver, chicken liver, fish, etc. Choose iron pan for cooking. If it is anemia caused by poor iron absorption function in the stomach, it is necessary to treat gastrointestinal diseases first.

5. Beware of "cerebral infarction"

The hottest summer has come. The human body perspires more, and the water loss in the body increases, especially in the elderly, which is less than that in the young. In addition, the physiological response is relatively slow, resulting in blood concentration and even "dehydration", which leads to an increase in blood viscosity and a stroke. In summer, we should take moderate physical activities, such as walking and jogging, treat patients with diabetes, coronary heart disease, liver and renal insufficiency in time, control blood pressure at a normal level, and pay attention to smoking ban and alcohol control.

6. Beware of air-conditioning diseases

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

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