Lips in Sjögren’s syndrome represent one of the most visible areas where the body’s systemic lack of hydration is manifested. In an optimal state of health, the minor salivary glands located in the oral mucosa keep the lips moist and flexible. However, this biological balance is drastically interrupted when the organism activates an erroneous response against its own tissues. This pathology is defined as an autoimmune disease where the immune system identifies exocrine glands as external threats. Therefore, chronic inflammation occurs, which degrades the secretion capacity, resulting in a decrease in the production of saliva and other protective fluids. Consequently, the physical result is cracked, dry lips that are vulnerable to external injuries.
Moreover, the lack of constant lubrication causes the delicate skin of the lips to lose its natural elasticity. It is important to highlight that the symptom of dry mouth, or xerostomia, is often accompanied by a persistent burning sensation in the perioral area. Nevertheless, the damage is not limited to the surface, as the absence of saliva favors the proliferation of fungal or bacterial infections. As a result, the corners of the lips can develop small, painful fissures that make everyday gestures like speaking or smiling difficult. Furthermore, Sjögren’s syndrome is a condition that predominantly affects women and requires constant monitoring of oral hygiene.
For this reason, the schematic illustration of this condition highlights how the skin of the face also suffers due to the low activity of the sweat and salivary glands. In view of this, treatment must focus on the application of specific hydrating balms and frequent fluid intake. Due to the fact that the immune system attacks parts of its own body by mistake, inflammation can spread to other mucous membranes in the body. On the other hand, the use of saliva stimulants and artificial tears helps to mitigate ocular and oral irritation. Accordingly, the feeling of dryness serves as a constant reminder of the need to regulate the patient’s defensive response.
Finally, the comprehensive management of lips in Sjögren’s syndrome seeks to restore tissue integrity and prevent dental complications derived from the lack of saliva. Although the disease is chronic, advances in immunology allow for more effective control of inflammatory outbreaks. In summary, early detection of persistent dryness is vital to avoid the deterioration of oral and general health. Ultimately, the main goal is to normalize patient comfort through therapies that replace missing natural secretions. Lastly, multidisciplinary follow-up ensures that all manifestations of this autoimmune disorder receive proper medical attention.
