When patients experience severe oral ulcers, it is generally not recommended to take acyclovir tablets, because acyclovir is used to treat symptoms caused by some viral infections. If the disease is caused by viral infections, acyclovir can be taken orally. When oral ulcers occur, they are generally caused by "internal heat" in the patient's body, possibly due to a decrease in resistance, leading to local mucosal ulceration, bleeding, and pain in the mouth. When patients have low resistance, it is suggested that they adjust their resistance appropriately, eat more fresh vegetables and fruits, ensure adequate rest, drink plenty of water, and adjust their lifestyle appropriately without overeating or drinking. Oral ulcers and acyclovir are not closely related, so it is advised not to take acyclovir tablets when oral ulcers occur. (Medication should be administered under the guidance of a physician.)

Can frequent oral ulcers turn cancerous?

There are many causes of oral ulcers, they recur easily, and heal slowly. Frequent ulcers make many people worry about the possibility of cancerous changes. If an oral ulcer does not heal over a long period, there indeed is a tendency for it to turn cancerous. Chronic ulcers are also a cause of cancer, so it is essential to pay attention to one's oral health. For instance, oral ulcers must be treated promptly to eliminate the cause and provide symptomatic treatment. Treatment methods should combine systemic and local treatments. It is especially important to pay attention to those oral ulcers that do not heal over an extended period, as they are precancerous lesions and are very likely to turn cancerous. A biopsy may be necessary to make a definitive diagnosis to facilitate timely treatment.

Can stomach fire cause oral ulcers?

When there is excessive stomach fire, it can cause oral ulcers. This is because excessive stomach fire leads to poor digestion in the gastrointestinal tract, where food cannot be digested in time and regurgitates into the mouth. It can also cause throat pain and oral inflammation, so it is crucial to treat stomach fire promptly. For severe cases, medication that improves stomach fire should be taken, and for mild cases, the condition can be managed through diet. Eating more watermelon, apples, and similar foods can help reduce stomach fire. Most importantly, avoid alcohol, smoking, and staying up late. (Medication should be taken under the guidance of a professional doctor.)

Difference between oral ulcers and thrush

Oral ulcers and thrush are somewhat different. First, oral ulcers can occur in people of any age, but are more common in the elderly and children, mainly due to a low immune system. Thrush, on the other hand, commonly occurs in infants within the first six months after birth, mainly caused by an infection with Candida albicans. Clinically, oral ulcers may present with redness, swelling, and significant pain. Thrush is an infection by Candida albicans that occurs on the newborn's tongue, which may affect the infant's feeding, causing crying or refusal to eat. Generally, thrush is caused by an infection with Candida albicans and is a type of fungal infection, whereas most oral ulcers are due to poor nutrition or unbalanced nutrition.

What are the signs before the onset of oral ulcers?

Oral ulcers are a type of erosion of the oral mucosa that generally do not show any particular signs before they develop. They may occur when a person’s immune resistance is low, possibly associated with symptoms of "getting heated" (a traditional Chinese medicine concept often referring to inflammation or infection). When oral ulcers occur, the affected area of the mucous membrane becomes eroded and painful, creating a sensation of a foreign object in the mouth that can disrupt the eating and drinking habits of the patient. Eating can become painful, and in severe cases, the patient might be unable to eat at all. Therefore, it is advised that patients seek timely treatment for oral erosion to avoid affecting their intake of food. During this time, nutritional supplementation is necessary for healing. If nutrition is not adequately maintained, it might impede the healing of the eroded oral tissue.

What is oral ulcer?

Oral ulcers refer to the erosion and inflammation of the mucous membranes in the mouth, a common ulcerative condition occurring on the mucous membranes of the oral cavity. They commonly appear on the inner side of the lips, tongue, underside of the tongue, cheek mucous membranes, vestibular groove, soft palate, etc. They may be accompanied by symptoms like bad breath, chronic pharyngitis, constipation, headaches, dizziness, nausea, fatigue, irritability, fever, and swollen lymph nodes. There are two types of conditions: one is recurrent mouth sores, also known as aphthous stomatitis; characterized by repeated outbreaks but heals without scarring. The other type is called periadenitis, where there is a red halo around the eroded area that heals with scarring. Therefore, it is advisable to rinse with saltwater regularly, maintain oral hygiene, consume zinc-rich foods, regulate emotions, avoid staying up late, smoking, and drinking. This can promote the healing of oral ulcers. Additionally, under the guidance of a doctor or pharmacist, some heat-clearing and detoxifying traditional Chinese medicines can be taken.
