What causes insufficient body fluids?

Deficiency of body fluids may result from either physiological or pathological causes, such as diabetes and nephrotic syndrome.

I. Physiological Causes

When the body is exposed for prolonged periods to dry, hot, or polluted environments, the rate of water evaporation increases, leading to dehydration or insufficient moisture. Additionally, chronic excessive alcohol consumption, heavy smoking, and irregular eating habits can disrupt normal metabolism, resulting in fluid loss and impaired secretion and metabolism of body fluids.

II. Pathological Causes

1. Diabetes

Patients with diabetes have higher-than-normal blood glucose levels. Hyperglycemia causes water to shift into the bloodstream from tissues, leading to dehydration of bodily tissues and organs, often manifesting as dry mouth and thirst. Prolonged hyperglycemia can lead to neuropathy, impairing the secretory functions of the mouth and throat, thereby reducing the production of body fluids.

2. Nephrotic Syndrome

Patients with nephrotic syndrome experience symptoms such as proteinuria and edema. Because protein molecules are too large to be easily filtered by the glomeruli, they are lost in the urine. This leads to imbalances in the body's water and electrolyte levels, causing symptoms of body fluid deficiency such as dry mouth and thirst.

In addition to the above, conditions such as oral cancer may also contribute. It is recommended to seek timely evaluation and treatment at an internal medicine or dental clinic for initial diagnosis and management of symptoms.
