When patients suffer from allergic cheilitis, their lips are generally in a state of acute inflammation. It is important to pay attention to their diet and avoid eating spicy, irritating foods such as hot pots or barbecues, as well as oily and greasy foods. During this time, it is also advised that patients should not smoke or drink alcohol, as some may experience severe itching due to the cheilitis. At this time, it is recommended that patients apply anti-allergic ointment locally, which can effectively relieve some symptoms of allergic cheilitis. Additionally, when suffering from allergic cheilitis, patients should avoid consuming seafood, as it is more likely to provoke allergic reactions. Therefore, to alleviate allergy symptoms, it is advised that patients avoid seafood during this period.
