Many people complain of recurring tongue ulcers. Sometimes, this is due to common causes like stomach heat, vitamin deficiencies, spicy or pungent foods, poor oral hygiene, or frequent tongue cleaning. Stress and hormonal changes can also be a contributing factor. Some people experience this problem repeatedly, making it difficult to eat, drink, and even speak.
Identify the cause immediately
Although in most cases, tongue ulcers clear up within a few days, if they persist or recur, they could be a sign of a health problem. Therefore, never ignore them and consult a doctor immediately.
According to Dr. L.H. Ghotkar, Director of Medicine at Lady Hardinge Hospital, frequent or long-lasting ulcers on the tongue can be a sign of an underlying problem. This could be related to digestive issues, weakened immunity, or nutritional deficiencies. Sometimes, it could also be a sign of an infection or allergy.
If the blisters are accompanied by severe pain, bleeding, or persistent blisters, they may be a sign of a serious illness. In some cases, they are caused by poor oral hygiene or a bacterial infection. Persistent blisters may also be a sign of weakness or illness. Therefore, recurring blisters should not be ignored.
What can you do to prevent tongue ulcers?
A proper diet and healthy eating habits are essential for preventing tongue ulcers. Avoid eating highly spicy, sour, or pungent foods. Maintain good oral hygiene and drink plenty of water daily. Include foods rich in vitamins B and C, such as fruits and green vegetables, in your diet. Avoid tobacco and alcohol.
If you notice any symptoms, consult a doctor…
If tongue ulcers don't heal within 10 to 15 days or are accompanied by severe pain, swelling, fever, or bleeding, this could be a serious symptom. If you're having trouble eating or losing weight, don't ignore them. Long-lasting ulcers could be a sign of a more serious problem. Therefore, timely diagnosis and proper treatment are essential.
