Sign · 大便干结
Dry, hard stool
Small, dry stool that is difficult to pass, sometimes pellet-like.
This page is a reference entry, not an assessment. It says which patterns the sign belongs to in the table this site is built on, at what weight, and where else on the site it appears. Having a sign is not having a pattern — most people have several of these at once, and the self-check is where they are weighed against each other.
What weight it carries
Every sign in the table is filed against one or more patterns at one of three weights. The weight is about diagnostic usefulness, not severity: a defining sign is one the pattern cannot be argued without, which is a different thing from a sign that is dangerous.
| Pattern | 中文 | Weight |
|---|---|---|
| Kidney yin deficiency | 肾阴虚证 | Common |
| Damp-heat | 湿热证 | Supporting |
Common for one pattern
Usually present, and its absence counts against the pattern. ×2.
