A healthy person does not notice how he breathes. He thinks about it, he feels that he "did not have enough air," "cramps in the chest." Shortness of breath occurs whenever the body, trying to maintain the necessary life-blood oxygen levels, breathing accelerates reduction.
The signal of a lack of oxygen (its main distributors — heart and lungs) via the vagus nerve enters the brain and activates breathing center, which in turn instructs the speed rate of respiration. Dyspnea — Is, first of all, the response to increased physical activity: we are increasing the pace of walking, trying to catch up with the departing bus, etc. After such tests have to catch your breath — breathe. In this case, restore normal breathing sometimes takes time.
Recipe combat such dyspnea is simple, even banal: it is necessary to engage in physical exercise, walk more.

A thin probe is located at the end of the optical system allows you to examine the trachea and bronchi of all calibers. Dyspnea, due to dysfunction of the
But sometimes dyspnea may signal an acute heart failure or pulmonary edema. Ultrasound diagnosis of the heart, the daily study of heart rate, ECG monitoring and other studies will help determine the true cause rapid breathing in heart disease. If shortness of breath occurs at rest, it is — an evil sign, a signal of serious violations in the work of the body. Sudden and rapidly growing, it may be due to embolism (blockage) or pulmonary vascular rupture of lung tissue. Her appearance at night — often the result of failure of the heart rate, the development of congestive heart failure, heart attack or asthma.
In all these cases requiring emergency medical treatment. Often dyspnea arises because of the emotional stress. Strong emotion, anger, anxiety, fear, increase production of adrenaline. Once in the bloodstream, it causes the body to operate in hyperventilation (drive through the lungs too much air). Generated a storm of hormonal signals are sent to the central nervous system, which is being raised, forcing more likely to contract respiratory muscles. The higher the intensity of emotions, the stronger shortness of breath. Emotions spur activity is not only light, but also of the heart. The increase in heart rate feels like a heartbeat. As soon as the leaves stressful situation, normal andbreath. Shortness of breath may be accompanied by a number of diseases not directly affecting the respiratory and circulatory system. So, it often occurs in thyrotoxicosis (excess thyroid hormone), and diabetes mellitus. Taking certain medications can also trigger wheezing. Sudden dyspnea a child may be associated with the ingress of foreign bodies in the respiratory tract.
So, if the shortness of breath began to appear during normal load for you, alone, at night, or it is accompanied by other unpleasant sensations (pain in the heart, irregular heartbeat, dizziness, weakness, shortness of breath or exhalation), without delay, go to the doctor.
