Chap. 6. Of Diabetes, or extraordinary Pissing.
DIabetes is a quick and plentiful sending forth of Drink by Urine; after which there comes a violent Thirst, and consuming of the whol Body.
It is called Diabetes apo tou diabainein, from passing through, as Water through a Conduit pipe, which is called Diabetes. This Disease is also called Dipsacos, from the unquenchable Thirst, and the Piss-pot Dropsie, from the continual making of Water. It is seldom seen, for Galen in 6. de loc. aff. cap. 3. saith that he saw it but twice.
The next and immediate Cause of this Disease, from Galen, and al his followers, is held to be a hot distemper of the Reins, which makes them draw Water violently from the Veins, and send it to the Bladder being not able to contain it themselves; the Veins being drawn dry, suck from the Liver; the Liver from the Guts and Stomach; hence comes a continual Thirst after drink, which as soon as it is taken, it is forthwith carried from the Liver and Veins into the Reins▪ where by its quantity it sti••reth up the Expulsive Faculty, and burdening the Retentive Faculty, it is sent to the Blad∣der.
Some suppose that this cause is insufficient, because the hot distemper of the Reins is an usual dis∣ease, but Diabetes is very rare; therefore there must be somthing else that is less usual, namely, a sharp or salt Matter in the Kidneys, either of ••holler or of Flegm, which doth continually provoke the attractive vertue of them; as in Chollerick Feavers there is a Thirst which cannot be quenched, from the Chollerick Humor which is fixed to the coat or Tunicle of the Stomach, or from Chollerick Vapors sent from some adjacent part into the Stomach, by the motion of some putrid Choller which lodgeth there. This Opinion is probable; but we think good to add thus much to it, That the Kid∣neys alone are not affected in this Disease, because Choller and other burnt Humors are first bred in the Liver; and therefore they cannot be in any quantity in the Kidneys, but the Liver must parti∣cipate of them. And if we may reason where Nature seems to be ••ilent, we can say that there is a ve∣nemous quality concurring for the producing of this Disease. For that kind of Serpent called Dip∣sacos, found in Lybia, when it bites any man, doth send into him such a poyson as begets an unquen∣chable Thirst. The like kind of venom may be bred in our Bodies, by a peculiar corruption of some humors, which may cause such a Thirst; for Galen testifieth that divers kinds of poysons may breed in our Bodies. And if such a kind of poyson may be bred in our Bodies as may cause a detestation of
