Rheum

Rheum is a term that refers to a thin discharge of the mucous membranes, especially during sleep. This discharge can consist of mucus, skin cells, oils and other materials that can accumulate in the corners of the eyes or the mouth. Rheum is not typically a sign of disease or any other medical condition.

Causes

Rheum is a natural part of the body's defense mechanisms. The mucus membranes of the eyes and mouth produce a protective layer to keep these sensitive areas moist and to trap and remove any dust particles or other irritants that may come into contact with them. During sleep, this protective layer can dry out and accumulate, forming what is commonly known as "sleep" in the corners of the eyes or "drool" around the mouth.

Types

There are three types of rheum:

• Gound is the type of rheum that is found in the corners of the eyes upon waking. It is typically white or slightly yellow in color and has a sticky or crusty texture.

• Mucous is a type of rheum that is found in the mouth. It is typically clear or slightly white in color and has a slimy texture.

• Serous is a type of rheum that is found in the eyes and mouth during periods of emotional distress or crying. It is typically clear in color and has a watery texture.

Treatment

In most cases, rheum does not require any treatment. It can be easily removed by wiping the corners of the eyes or mouth with a soft cloth or tissue. However, if the rheum is excessive, persistent, or accompanied by other symptoms such as redness, swelling, pain, or vision changes, it may be a sign of a more serious condition and should be evaluated by a healthcare professional.
