Pathology

This is a description of the pattern in its acute stage, when the Spleen is invaded by exterior Dampness. The pattern can also become chronic, in which case the tongue would be more Pale and the pulse partly Weak or Soggy.

What causes the characteristic feeling of heaviness is the fact that Dampness obstructs the muscles. It also impairs the the clear Yang from ascending to
the head, hence the feeling of heaviness in the head as well.

The feeling of fullness is caused by Dampness preventing the normal movement of Qi. This also causes the nausea as Dampness prevents Stomach-Qi from descending (Qi becomes Rebellious). 

What causes the sweet taste in the mouth (or sometimes the absence of taste) is because the Spleen opens into the mouth: disruption to its normal behavior will have repercussions in the mouth.

Lastly Dampness is heavy and has a tendency to drop downwards; this is what causes the excessive white vaginal discharge we see in some cases.

Causes

Precursor patterns: Cold-Damp invading the Spleen can derive from Spleen Qi Deficiency

Exposure to exterior Dampness: This can be due from the weather or from someone's living conditions (e.g. living in a damp basement flat).
