What is a common cause of burning tongue in uncontrolled diabetics?

1. Allergic reaction

2. Malnutrition

3. Infection

4. Acid reflux

The correct answer is: Malnutrition

The sensation of a burning tongue, or glossodynia, in uncontrolled diabetics is often associated with malnutrition, particularly deficiencies in essential nutrients such as vitamins and minerals. Diabetes can impact how the body absorbs these nutrients, and when the nutritional status is compromised, it can lead to changes in the oral mucosa, resulting in symptoms like a burning sensation on the tongue. Malnutrition may also be exacerbated by other factors in diabetic patients, such as dietary restrictions, glucose dysregulation, and the paradoxical weight loss that can occur in uncontrolled diabetes. Additionally, inadequate saliva production due to diabetic neuropathy can contribute to dryness and irritation of the oral tissues, which may further intensify the burning sensation experienced. In contrast, while allergic reactions, infections, and acid reflux may cause similar symptoms, they are less commonly linked to the specific context of uncontrolled diabetes as a primary contributing factor. Understanding the relationship between diabetes management and nutritional status highlights the importance of monitoring and addressing these issues to prevent complications such as burning tongue.
