Does Asthma cause High Blood Pressure

Asthma is a chronic lung inflammation in the bronchial tubes which causes narrowing, swelling and blocking of airways thereby leading to difficulty in breathing. High blood pressure or hypertension is a problem of increased tension in the arteries during blood pumping through the heart. Nowadays many people are suffering from both asthma and high blood pressure.

Does Asthma cause High Blood Pressure

Yes, asthma causes blood pressure in adults. Studies have confirmed about asthma inducing high blood pressure. But it is not sure if asthma affects hypertension in case of adolescents.

How Does Asthma cause High Blood Pressure

The blood for a normal person moves from the lung to the left ventricle through the left atrium. From the left ventricle, blood is pumped to all the peripheral parts of the body through the arteries. High blood pressure means the pressure of the blood in the arteries is more than the normal. For an asthmatic patient, the respiratory passage is constricted due to which he faces difficulty in breathing and needs expansion of respiratory airway. So, he consumes medicine that targets the beta receptors lining the respiratory passage to expand the respiratory airway. These medicines sometimes expand the blood vessels too and thus cause high blood pressure. Metered Dose inhalers (MDI) are a part of asthma medication consumed by most of the asthma patients which simulates the beta receptors.

What is the Treatment for Hypertension caused by Asthma

Treatment to reduce the high blood pressure is consuming blood pressure tablet with diuretics and beta-blockers. The beta-blockers can block the beta-receptors activation and avoid the blood vessels from widening and thus reduce hypertension by dilating the blood vessels.

Does Asthma also cause Low Blood Pressure

The bronchial tubes of an asthmatic patient get constricted and so the patient has to breathe harder to expand the wall of the thorax due to which a high magnitude of negative effect is produced in the thoracic cavity. Due to this negative effect, the blood is sucked back to the lung itself than moving into the left atrium. This decreases blood in ventrium leading to decrease in blood expelled out from heart to arteries (lower stroke volume). Due to this scenario, pressure in artery becomes low leading to low blood pressure, though the body tries to compensate it by increasing both the heart rate (baroreceptor reflex) and the peripheral resistance.


The asthma and hypertension medications have contradictory effect on beta receptors. So when medicines are to be consumed for both asthma and hypertension, Doctor Consultation is mandatory.

Does Asthma cause Chest Pain

Is Asthma causing Chest Pain

Yes. Asthma induces chest pain. While breathing in and out, the chest pain will be constant for some people and it will increase for some other patients. For few asthma patients, chest pain will be mild and for few others, the pain will be severe, based on how well the patient controls asthma. Similarly, the chest pain in the asthma patient can be concentrated or diffused when it is caused by the lungs. Severe cough due to asthma cause strain and pain to chest. In case of severe chest pain, the patient has to immediately contact the Doctor and get treatment.

When does Asthma cause Chest Pain

Asthmatic patients have a feeling of tightness in their chest when asthma is severe. Many asthma patients have this problem and they live with it. When the asthma is controlled in the patient, chest pain also gets reduced. But the patient must consult with the Doctor to confirm if this chest pain is a symptom of asthma or heart attack or angina.

How does Asthma cause Chest Pain

The lungs and the inside of the chest are covered by a membrane called pleura. The space in between the two pleural membranes is called as the pleural cavity.
This pleural cavity is filled with a fluid which helps in lung contraction and relaxation while breathing. Any problem in pleura leads to problems in breathing and severe chest pain.

Secondary or Tension pneumothorax

which is used to term lung collapse, might happen to an asthmatic patient if asthma attack is severe. Lung collapse happens when the lungs capacity to hold air gets reduced and so the air in the lung more than its capacity enters pleura and gets filled there. As the air capacity in the lung is reduced, breathing becomes very difficult and breath is shortened. This happens if the patient has been affected by severe asthma attack leading to chronic lung problem. This causes chest pain not because lung has insufficient air but because of air in pleura and the nerve endings are at pleura and not at the lungs.

What is the Treatment for Secondary or Tension Pneumothorax

Treatment for secondary or tension pneumothorax is done by inserting a needle below the lung into the pleural cavity which releases the air. The severity of the lung collapse will then get reduced and the asthmatic patient has to be admitted in hospital for further treatment.
