Children's breath-holding seizures are caused by physical factors such as emotional stimulation, unsatisfied demands and pain. At first, the baby will cry, and then after hyperventilation, he will hold his breath and pause. Because there is no oxygen inhalation, carbon dioxide will accumulate in large quantities, and the baby's lips will turn from red to blue and finally to purple. At the same time, limb stiffness occurs, and some babies even have limb convulsions. The whole process is as short as 10 minute and as long as 2 ~ 3 minutes, and then they start breathing again, relax their muscles and gradually regain consciousness.
If your child just cries and his lips are purple, it can't be diagnosed as a child holding his breath. If parents can't dispel their children's doubts, they can take their children to have an EEG examination when their lips are purple.
