2. Blue Lips
Another very scary sight for a parent, friend, or onlooker is that the lips can end up turning blue. The reason for this, is that the patient’s body is directing a lot of their blood away from the surface of the skin around the lips (this is what makes the lips appear red in the first place) and instead directing it toward the internal organs in order to protect them during this event.
This is then exacerbated by the extreme tension that the patient is under as they clench everything up and thus restrict the blood flow to some extent. For all these reasons, the lips can turn blue – but don’t worry as this isn’t necessary a dangerous sign.
