Symptoms of Asthma - Part 2
Written by Clive Chung on 2:37 AMPeople with asthma should be wary of taking beta-blockers. These drugs slow the heart rate and lower the blood pressure. They have the opposite effect to asthma-relieving beta-agonists. Beta-blockers can cause breathing difficulties. They have been known to trigger severe, even fatal, asthma attacks. So even if they have been prescribed to treat another condition, it would be advisable to speak to your doctor and say that you are concerned about taking them because of your asthma. He can then either put your mind at rest or prescribe something else. Beta-blockers are used to treat high blood pressure, migraine and they can also be used in eye drops to treat glaucoma.
In additional to those described above, there are other symptoms which can prove troublesome. The most important of these are:
Chest discomfort or tightness
This is a very common symptom of asthma and often occurs during an asthma attack because air that is not being released through the airways becomes trapped in the lungs. The lungs expand and the membranes surrounding them stretch, and this can be painful.
Nasal problems
A runny nose and nasal congestion is often an accompanying feature of asthma. This can be caused by the swelling of the nasal passages or by nasal polyps. The latter can be treated either by medication or surgery. These polyps are non-cancerous.
Lethargy
People often feel very tired and lethargic when their asthma is bad. This can be due to a diminished supply of oxygen to the body. On the other hand, if the asthma has been triggered by flu or cold or other viral condition, the tiredness could be an after-effect of the illness as well as of the asthma itself.
