Patient's question:
My nephew has only been born for over a month. I heard that the child is usually quite good and doesn't cry much, but recently these last couple of days, I've noticed him trembling in his limbs and don't know what's wrong. It's not too severe. What could be causing the trembling limbs in newborns?Doctor's answer:
The brain nervous system of newborns is not fully developed, so sometimes the cerebral cortex may be immature, and the excitability of central nervous cells is relatively high. This phenomenon gradually disappears. If the tremors are severe and do not improve over time, it is best to see a doctor for a specialized examination to identify the specific cause and receive appropriate treatment. If the child also has symptoms such as diarrhea or vomiting, it may lead to imbalances in electrolytes such as potassium, calcium, or magnesium. In this case, the child may also experience tremors in their limbs, but these tremors are relatively mild. Blood electrolyte tests can be conducted for further confirmation. If there is a deficiency of potassium, it is important to promptly supplement potassium for the child.
