Patient's question:
A 6-month-old baby cannot lift their head, can roll over, has a normal appetite, and shows no significant abnormalities, but sometimes they shake their head. Why do they always bite their lips?Doctor's answer:
Biting the lips is usually caused by insufficient rest, where the nerves cannot properly control the muscles to perform normal chewing activities. Therefore, if you experience biting your tongue while eating, it's important to pay attention to getting adequate rest.Another theory suggests it's due to "internal heat" (), where the gums on both sides of the teeth become slightly swollen, making it easier to bite the tongue. It could also be caused by conjunctivitis. Treatment primarily involves medications like ofloxacin eye drops. I recommend you have an eye examination for a definitive diagnosis and maintain good eye hygiene. Additionally, avoid spicy and irritating foods.
