What is airway hyperresponsiveness

It should not be caused before the confinement, the reasons should be as follows, now the only way to improve your own resistance.

1. Physiological changes during pregnancy, due to the increase in uterine and placental blood flow, increased oxygen consumption, increased estrogen secretion and other factors can cause tissue mucosal congestion and edema, capillary congestion, mucus gland hypertrophy, so 30% of pregnant women have rhinitis-like symptoms, and can also show nasal obstruction, nosebleeds, voice changes and other symptoms. With the enlargement of the uterus, the abdomen is distended, the anteroposterior diameter of the abdomen increases, and the range of motion of the diaphragm is limited; The release of hormones during pregnancy can change the elasticity of the chest wall. Changes in lung function due to changes in the diaphragm and chest wall caused by pregnancy lead to changes in lung function.

2. Changes in lung function Pregnancy can lead to changes in the parameters of ventilation and gas measurement related to asthma. There are differences in volume and flow, but in general, the reduction in lung volume is not significant. Differences in gas measurements versus progesterone levels acting on the respiratory center.

With hyperventilation, the gas flow increases while the frequency does not change, and the pH remains unchanged due to increased renal excretion of bicarbonate.

3. In the first trimester of pregnancy, the rib cage changes, the costodiaphragmatic angle widens, the rib cage expands outward, the transverse diameter of the chest cage widens, the circumference increases, and the diaphragm rises, so the diaphragm activity increases when breathing. Maternal oxygen consumption increases by 10 20 in the second trimester, while lung ventilation increases by 40, so hyperventilation occurs. This increases the partial pressure of oxygen in the maternal arteries by up to 105 mmHg and reduces the partial pressure of carbon dioxide to 32 mmHg, which is conducive to providing the oxygen needed by the mother and the fetus.

In the third trimester of pregnancy, with the enlargement of the uterus, the diaphragm rises, the range of activity of the diaphragm decreases, the breathing of pregnant women is mainly in the chest position, the gas exchange remains undiminished, and the number of breaths does not change much, but the breathing is deeper. Pregnant women are prone to upper respiratory tract infection due to congestion and edema of the nasopharynx and respiratory tract. In addition, although lung function does not decrease during pregnancy, due to the increase in oxygen demand of pregnant women, the condition is more likely to worsen when pregnancy is complicated with respiratory diseases.

Hello, in this case, you can take Yinhuang granules, wheezing tablets, and go to the hospital if necessary**.

Of course, ketotifen can be used, this drug is an H1 histamine receptor antagonist drug, which can be used for airway hyperreactivity caused by allergies, and the effect is still good, the pharmacy says "no one prescribes", it does not mean that this drug has no effect, and, from the situation you described, you were treated in a regular public hospital, so you should follow the doctor's instructions to carry it out.

You have to thank you for your "illness", which is actually normal, but you have a lot of excuses not to smoke secondhand smoke! Don't go to places with bad environments. This is not actually a disease.

Airway hyperresponsiveness is a presentation.

You'll need a test: lung function plus bronchiectasis test, which will determine if you have bronchial asthma.

It is necessary for you to make a diagnosis, because the ** of asthma is very different. For example, long-term inhalation of sulitide, standing bronchodilators, etc.

I don't know, but I think it's time to take a look at Chinese medicine, generally with Western medicine can't cure the disease, everyone looks at Chinese medicine...
