Chap. 6. Of Singultus, or Hiccough.
SIngultus or Hiccough, is a depraved Motion of the Stomach, by which it desires to expel som∣thing that is hurtful.
It is distinguished from vomiting, because that which is so sent forth, is contained in the Cavity of the Stomach; and it is wholly turned to throw it out: But in Singultus the matter offending is fixed in the Tunicles of the Stomach, therefore it doth contract it self, and shakes its fibres, to exclude it. And that we may comprehend loathing also in this Definition, we say that the expulsive motion of the Stomach is three waies: For either Nature would somtimes rise to expel, and cannot; or it is not sufficiently raised to this motion, and then it is Nausea or loathing: somtimes it riseth and expel∣leth, and then it is Vomiting: or lastly, it riseth to expel, and cannot, and that is Singultus.
This is a Convulsive Motion, not a Convulsion, which is only in the Muscles, and parts given to voluntary Motion.
The immediate Causes of Singultus are propounded by Hipp. Aph. 39. Sect. 6. that is, Empti∣ness and Repletion, as of a Convulsion. But Galen and Avicen ad a third Cause, namely, a pro∣vocation by a sharp matter. Some labor to bring the matter provoking to a kind of repletion, that they may excuse Hippocrates. But when the matter is plain, we need not confound and darken the evidences of things for Authors words: For what is more cleer, than that Singultus comes from the expulsive faculty provoked? Therefore whatsoever can provoke is the immediate cause of Singultus or Hiccough. But Humors and Vapors offending either in quantity or quality may prov••ke the Stomach to expulsion, and so repletion and acrimony are two distinct causes. But it is not ea••e to shew how emptiness makes a Singultus: For since its Essence is in defect, none will say that Nature riseth to expel a defect; but rather will be moved to refresh and repair it, and so it doth rather move the Attractive than the Expulsive Faculty. But if Singultus follow great Evacuations, as in sharp Feavers, and malignant, and purging with Hellebore, it is not simply to be attributed to the Evacuati∣on, but rather to a malignant quality in the Stomach, coming from the Disease, or some Medicine taken.
The Matter causing Singultus is either gathered in the Stomach, or sent from the Liver, Spleen Guts, or other parts; or from the whol Body. So sharp Nourishment, or sharp Medicines, or sharp Humors, or gnawing Worms contained in the Stomach, cause a Singultus by propriety: but infla∣mation of the parts adjacent by water or vapors sent to the Stomach, make it by consent: as also be∣cause the Tumor, especially when the Liver is inflamed, doth compress the Stomach by which the ex∣pulsive faculty is continually provoked. Finally, Humors may be brought from the whol Body, or sharp humors to the Stomach, in diseases of the whol Body, as appears in sharp and malignant Feavers.
The Diagnosis, or knowledg of this Disease, is manifest of it self. But the signs of the Cause are thus to be distinguished, so that if it be by propriety, the disease is more lasting, and there will ap∣pear signs of the Humors contained in the Stomach, and the disease is a••••waged by Vomit. The Hu∣mor contained in the Stomach is known by vomit, belching, taste in the mouth, and by other signs. And finally, if it come from a disease in any other part, you may take the signs thereof from their proper Chapters.
As to the Prognostick: Singultus that comes from any principal Cause as Meat, Drink, or Cold, is not dangerous; as also that which goes before a Crisis by Vomit, and then other signs must be healthful.
If any have the Hiccough in a great Feaver, the Disease is very dangerous, Hipp. in Coacis. For it comes from sharp Humors, and malignant, which pull the Tunicle of the Stomach in wardly, and force its expulsive faculty. And Vallesius saith, that he never knew any extenuated persons taken with a hot and malignant Feaver▪ who had a Singultus, to escape: So it is in Hipp. 3. Epid. Sect. 2. Aegr. 12. A woman living in the Market, had many Hiccoughs upon the twelfth day, and died the fourteenth day of her sickness. Also Platerus observed, that a Singultus coming upon burning Fea∣vers, and continuing, is for the most part a forerunner of death, and the same is deadly in a Dysentery, or bloody flux.
