Symptom #2: Wheezing
Our airways need to be kept open at all times to allow air to flow in and out of the body freely. Any obstructions can make it difficult for the patient to breathe and this has the potential to be very dangerous. If the airways are narrower than usual for some reason, then this can result in a wheezing sound.
The sound of wheezing is caused by the air having to rush through a narrow passage, in much the same way that certain instruments make a sound. This can be very noticeable audibly and is a clear sign that the patient is struggling to breathe.
