Dry Mouth and Constipation: What Are the Causes?

There are several potential reasons why a person might experience dry mouth and constipation simultaneously. These symptoms can be connected to various underlying health conditions, and understanding the root causes can help in seeking appropriate treatment.

1. Digestive System Disorders

From a Western medical perspective, digestive tract inflammation is often associated with these symptoms. Conditions such as acute gastritis, chronic gastritis, gastroenteritis, bile reflux gastritis, or issues like gastrointestinal mucosal erosion, polyps, or exudation can lead to dry mouth and bad breath. These conditions may also cause bloating and constipation. In more severe cases, such as when there is a Helicobacter pylori infection in the gastrointestinal tract, the symptoms tend to worsen significantly. Additionally, other acute inflammatory conditions like appendicitis, pancreatitis, peritonitis, or cholecystitis can intensify symptoms including dry mouth, abdominal pain, bloating, and constipation.

2. Nervous System Disorders

Neurological issues, particularly those involving dysfunction of the autonomic nervous system or gastrointestinal vegetative nerve disorders, can also contribute to dry mouth and constipation. When the body's natural regulatory mechanisms are disrupted, it can affect both oral moisture and bowel function.

3. Chronic Medical Conditions

Long-term illnesses such as diabetes, chronic kidney disease, and congestive heart failure may also present with dry mouth and constipation as secondary complications. These systemic diseases often impact multiple organs and bodily functions, including digestion and hydration levels.

If you're experiencing persistent dry mouth and constipation, it's important to consult a healthcare professional to determine the underlying cause and develop an effective treatment plan.
