Don’t eat it next time. Eating betel nut for a long time is not good and may lead to throat cancer. This is not to scare you, it is based on science. Angular stomatitis, commonly known as rotten corners of the mouth, often occurs on one or both sides of the mucous membrane of the corners of the mouth. Due to different causes, it is divided into dystrophic angular cheilitis, coccal angular cheilitis, and fungal angular cheilitis. Nutritional angular stomatitis often occurs in people with nutritional deficiencies and vitamin B deficiency. Angular cheilitis caused by vitamin B deficiency is the most common. The initial symptoms include redness and itching at the corners of the mouth, and then the epithelium peels off, forming erosion, maceration or cracks. When the mouth is opened, it tears easily and bleeds easily. Eating and speaking are affected. This disease is not “getting angry” as people say. It is especially likely to occur in children who have a poor diet or have a picky eating habit, or who suffer from chronic diarrhea and dysentery. It is easy to get this disease in winter because the climate is relatively dry in winter, and vegetables and fruits are eaten relatively less. There is often a lack of vitamin C and B2, which causes the corners of the mouth to become dry and chapped. When the lips are dry, people like to lick them with their tongues in order to make the lips and corners of the mouth moist and feel temporarily comfortable. However, saliva evaporates quickly when it encounters dry air. This not only fails to solve the problem of dryness, but also brings microorganisms in the saliva to the cracks, causing bacterial infection and aggravating the inflammation of the corners of the mouth.

If you have angular stomatitis, you can apply some grease or anti-cracking oil on it. You can take vitamin B2, 3 times a day, 1-2 tablets each time. You can apply Bingbor powder or Yunnan Baiyao locally. If it has been eroded and inflamed, 1% gentian violet solution can be applied to the corners of the mouth twice a day. With these simple treatments, most angular stomatitis can be cured quickly. To prevent the occurrence of angular stomatitis in children, children should be allowed to eat rice noodles, green fresh vegetables, beans, millet, meat, milk, etc. Make sure to eat a variety of foods with a good mix of thickness and thickness, and educate your children not to be picky about their food. Children with gastrointestinal diseases should be treated aggressively. In addition, when the corners of the mouth are uncomfortable, do not lick them with your tongue to prevent the corners of the mouth from drying out and making them more likely to rupture and bleed. Coccal angular stomatitis is an angular stomatitis caused by streptococcus and staphylococcus infection, and is more common in elderly patients without teeth. It manifests as wet white spots at the corners of the mouth on both sides, erosion or ulcers, and may also involve suppuration, bleeding, and scabs. Treatment should be based on local cleaning and application of antibiotics (such as erythromycin ointment). Broad-spectrum antibiotics can also be taken orally. Fungal angular cheilitis is angular cheilitis caused by fungal (mainly Candida albicans) infection. It manifests as moist whiteness at the corners of the mouth on both sides and the whiteness is more obvious, with erosion or ulcer, often accompanied by cheilitis and lip erosion. Candida hyphae can be seen on PAS staining. Treatment should be done by washing and drying the area with nystatin solution, and then applying nystatin, clotrimazole, miconazole, etc. to the area. Note that broad-spectrum antibiotics should not be used for this disease
