When patients have oral ulcers, taking vitamin C can help repair the ulcers to some extent. However, it is generally recommended that patients use local medications in the mouth, which can provide quicker and more noticeable results. Sprays specifically for oral ulcers can be directly applied to the affected areas, or patches designed for oral ulcers can be adhered directly to the lesions, which can effectively help in healing the ulcers. Additionally, patients may appropriately take some oral vitamins that can effectively enhance the body's resistance and aid in the recovery from certain ailments. It is important to maintain correct dietary and lifestyle habits and pay attention to oral hygiene.

What causes purple lips and mouth ulcers?

There is the appearance of cyanosis of the lips and oral ulcers, which might be associated with a deficiency in certain vitamins or trace elements. It is advised to visit a hospital to complete tests related to trace elements and electrolytes, among others. Additionally, the cyanosis of the lips also necessitates the exclusion of potential hypoxia. It is important to observe if the patient experiences chest tightness, coughing, expectoration, shortness of breath, and other symptoms. If necessary, completing a blood gas analysis to confirm whether there is hypoxia or carbon dioxide retention may be required. It’s important to maintain a balanced diet, ensuring good eating and living habits, and avoiding selective or picky eating to prevent changes or exacerbation of the condition. It is also advised to have regular follow-up visits at the hospital.

What should I supplement for frequent oral ulcers?

Oral ulcers are a common disease that many people encounter. Those who have long-term, non-healing oral ulcers often worry about the possibility of oral cancer, causing them considerable concern. The factors contributing to the onset of oral ulcers include genetics, infection, immune responses, and local irritation from foreign bodies. A deficiency in nutrients is also a significant factor; deficiencies causing oral ulcers mainly include a lack of vitamin B2, folic acid, trace elements, zinc, iron, and other cases of poor nutrition. Therefore, it is advisable to consume more fruits and vegetables in the diet to supplement vitamins and sufficient nutrients, preventing the occurrence of oral ulcers.

How to manage oral ulcers in summer

When patients experience oral ulcers, it may be due to hot weather in the summer or poor diet, leading to loss of appetite and lack of certain nutrients. It is recommended that patients adjust their diets accordingly, consuming light foods and staying hydrated. If patients lack appetite, they can eat some fresh vegetables and fruits to adjust their diet. Additionally, it is crucial for patients to avoid spicy and irritating foods, as these can worsen the ulcers and cause symptoms of heatiness. Therefore, during summer when experiencing oral ulcers, local treatment is also necessary. Topical medications for oral ulcers can be used to help heal the ulcerative lesions.

How should oral ulcers be treated to get better?

A very obvious symptom of oral ulcers is pain, which severely affects the patient's life, especially when abstaining from spicy foods. So how should oral ulcers be treated? First, the principle is to use local anti-inflammatory treatments to relieve oral pain and promote the healing of the ulcers. Generally speaking, the acute phase can be quite painful. Local medication can be used, including some pain relief medications. These can be appropriately applied to the ulcer site and reapply twice to achieve temporary pain relief. Generally, we can eat more fruits and vegetables and appropriately supplement water to keep bowel movements smooth and the mouth moisturized. Avoid excessive fatigue, strengthen physical exercises to enhance immunity, and locally use pain relief and anti-inflammatory medications. Some powders that can be applied to the ulcer site also promote healing. For those with recurrent systemic episodes, medications that enhance resistance and appropriate supplements of vitamin C can be used. (Medications should be used under the guidance of a doctor.)
