The Guts containing the Excrements must needs be afflicted in every Constipation or binding: either pri∣marily when they are stopped, or secondarily when they have lost their expulsive faculty.
When the Guts are straitned, so that the passage of the Excrements is hindered, the Belly is bound. And this straitness may come from astriction or Convolu∣tion.
We call it Astriction when the Guts have lost their slippriness, * 1.1 and are dried and wrinkled; or when they are bound and made straiter. Hence is it that Dri∣ers, Binders, sower and sharp things taken, as they astringe the Gullet and wrinkle the Jaws; so if they be taken imoderately especially fast∣ing, they stop the Guts and their passages, and bind the belly. And this may come from long fasting, and too much evacuation. And from heat that drieth the guts, or rather the Excrements, as we shal shew. Some say that the Guts may be pressed and stopped by a Tumor in the Mesentery: but we think it not to be possible, because when a Woman is with child, that great Tu∣mor dorh not cause constipation without some other accident.
The thin Guts are somtimes so rouled together in the disease cal∣led Convolvulus, * 1.2 so that they are closed and the Excrements can∣not descend: but are vomited up, either with pain called Ileon, when the Guts are inflamed, or with re∣pletion of excrements without, Inflammation, as we shal shew in pains.
But this is most usual in Ruptures when the Guts fal into the Cods, from the breaking of the Peritonaeum; by reason of the evil position of the Guts.
There is an ordinary Consti∣pation from the Obstruction of the Guts with proper Excrements, * 1.3 not only when they abound, but when they are dry, hard, thick, clammy, and hinder the Excre∣ments that follow. This is usually in the Orifice where the thin Guts use to open themselves into the thick, by reason of the straitness there; where they have been so fixed, that the constipation hath been deadly as we have observed in Anatomy. This is often in the Co∣lon, in the great turning thereof before it comes to the Rectum, by the hard dung reteined and stopping and binding the Belly, with the pain of the Colick. And somtimes such hard dung is in the Arse-gut, and not voided without great straining, or help of Art.
The dung grows hard when the meat is too solid and dry; as we see in Dogs that eat bones: especially when they drink little. The same comes from the use of hot and dry meats. And it is in hot natures when the Liver and parts adjacent are too hot; in whom, if they go not every day to stool through long sitting, ri∣ding or lying in the bed (because the excrements fall down better when the body is upright or moved) the Excrements grow hard from their internal heat that drieth them. Hence it is that Senators, Riders, and old Men, complain of costiveness. And as it comes
