What Causes Blood Blisters When Eating?

Blood blisters in the mouth after eating may be caused by burns, trauma, food allergies, bacterial infections, viral infections, and other reasons. Standardized treatment should be provided promptly.

1. Burns: Eating food at a high temperature may result in burns to the oral mucosa, causing blood blisters. Under a doctor's guidance, an aseptic syringe can be used to pierce the blood blisters, followed by the application of medications such as Kangfuxin Liquid, Bingpengsan, and Qingdaisan directly onto the affected area. This helps alleviate pain and promote the recovery of oral mucosa. Avoid consuming excessively hot food to prevent re-injury.

2. Trauma: Eating dry or hard food may cause excessive friction to the oral mucosa, leading to blood blisters. An aseptic syringe can also be used to pierce the blood blisters under a doctor's operation, while maintaining oral hygiene to facilitate recovery.

3. Food Allergies: For individuals with sensitive constitutions who are allergic to certain foods, ingestion may trigger an allergic reaction, causing capillary dilation and increased permeability of the skin and mucosa, resulting in blisters, blood blisters, and accompanying symptoms such as itchiness. Antihistamine medications such as Loratadine Tablets, Ebastine Tablets, and Chlorpheniramine Maleate Tablets can be taken orally under a doctor's guidance to relieve allergic symptoms by blocking histamine H1 receptors.

4. Bacterial Infections: Ignoring food hygiene and consuming contaminated food may also lead to bacterial infections, causing local inflammatory reactions and symptoms such as blood blisters and papules. Oral medications such as Erythromycin Enteric-coated Tablets, Amoxicillin Capsules, and Azithromycin Dispersible Tablets can be taken as prescribed between 1 and 2 hours after meals to exert antibacterial and anti-inflammatory effects.

5. Viral Infections: Ignoring hygiene when eating may also cause viral infections, presenting the aforementioned symptoms. Medications such as Ribavirin Granules, Aciclovir Tablets, and Ganciclovir Dispersible Tablets can be taken as prescribed, preferably between 1 and 2 hours after meals, to inhibit and eliminate viruses and improve symptoms. Develop good lifestyle habits, maintain a balanced diet, and prevent adverse effects from improper diet.
