**Question:** All are true regarding Early Post-cibal syndrome, except

A. Increased salivary flow
B. Dry mouth
C. Difficulty swallowing
D. Weight loss

**Correct Answer:** D. Weight loss

**Core Concept:** Early Post-cibal syndrome, also known as Sjögren's syndrome type I, is a chronic autoimmune disorder characterized by dryness of the eyes (xerophthalmia) and mouth (xerostomia). It primarily affects the exocrine glands, specifically the salivary and lacrimal glands, leading to decreased gland function.

**Why the Correct Answer is Right:** Weight loss (option D) is not a typical symptom of Early Post-cibal syndrome. Although dry mouth and eyes can cause discomfort and affect diet, weight loss is a rare occurrence in this condition. In contrast, the other options are more commonly associated with the syndrome:

**Why Option A is Right:** Increased salivary flow (option A) is typically seen in the later stages of Sjögren's syndrome when the primary damage to the glands occurs. In Early Post-cibal syndrome, the glands are still functional, leading to normal or even increased salivary flow.

**Why Option B is Right:** Dry mouth (option B) is a common symptom of Early Post-cibal syndrome, leading to increased susceptibility to oral infections, oral mucosal changes, and discomfort while eating.

**Why Option C is Right:** Difficulty swallowing (option C) can be present in some cases of Early Post-cibal syndrome, although it is not a universal symptom. Swallowing difficulties may result from the involvement of the salivary glands in the oropharyngeal region or neuromuscular dysfunction.

**Why Option D is Incorrect:** Weight loss is not a typical manifestation of Early Post-cibal syndrome. While the condition can cause discomfort and affect diet, weight loss is not commonly observed in this condition.

**Core Concept Explanation:** Sjögren's syndrome is an autoimmune disorder where the immune system mistakenly attacks the moisture-producing glands, primarily the salivary and lacrimal glands. This can lead to symptoms like dry mouth (xerostomia) and dry eyes (keratoconjunctivitis sicca), as well as ocular and oral manifestations.

**Why Option A is Incorrect:** In Early Post-cibal syndrome, the glands are still functional, leading to normal or increased salivary flow. The primary symptoms focus on the reduced production of saliva and tears, which is not the case in option A.

**Why Option B is Correct:** Dry mouth (xerostomia) is a common symptom in Early Post-cibal syndrome, affecting the oral mucosa, teeth, and salivary glands, and causing discomfort while eating, leading to altered food choices and potential weight loss.

**Why Option C is Correct:** Difficulty swallowing (dysphagia) may be present in some cases
