The cause of frequent and severe thirst is sometimes the stomach due to the hot nature of the stomach and, especially, its mouth. It happens that such heat arises from burning during fevers, and some patients drink all the time, not being able to quench their thirst, and soon die from this. Similar heat also arises from drinking too much wine, strong and old, as well as from eating something that is actually or potentially very hot, for example, asafoetida or garlic; Often a person dies from old wine due to excessive burning, nausea and thirst. And sometimes such heat occurs from drinking salt water; Sea water sometimes increases thirst so much that nothing can be done to relieve it. Sometimes the cause is thirst-inducing medicines and foods that cause thirst, causing flushing and flow. Washing occurs, for example, when salty food induces the nature to wash it away by washing and tearing it off, and flow occurs, for example, when a viscous substance induces the nature to greatly soften it so that it passes through and does not stick; Sometimes thirst is caused by a coarse substance, since heat rushes towards it. Salted fish combines all these properties.
Or thirst arises due to the dry nature of the stomach; this happens either from the salty or sweet mucus present there, or from the bitter yellow bile. Sometimes thirst appears from boiling in the stomach, and sometimes it occurs with the complicity of other organs, as happens, for example, with diabitis, which is a kidney disease. We will mention this later in the paragraph on kidneys.
Sometimes thirst of this kind appears due to blockages in the passages between the stomach and liver, which prevent water from passing into the body, and the thirst does not calm down even if you drink a lot of water; this is similar to what is observed with dropsy and kulanja. Thirst also occurs due to the participation of the liver, when the liver becomes hot or swollen, or when its coldness becomes very intense and it does not attract water, and also due to the participation of the lungs, if they are hot, or the heart, if it is hot. Thirst also occurs due to the participation of the jejunum, esophagus or epiglottis and adjacent organs, if the fluid dries out in them and they shrink, or if they are very hot. Thirst also occurs due to brain diseases such as hot sarsam, mania and kutrub. The most intense thirst that arises as a result of disease of these organs and with their complicity is the thirst that rises from the mouth of the stomach, then the thirst that rises from the esophagus, then the thirst that rises from the bottom of the stomach, then the thirst that appears as a result of the complicity of the lungs, then thirst due to the participation of the liver, then thirst due to the participation of the jejunum. Thirst sometimes arises as a result of the participation of the whole body, as happens during fevers and crises, as well as in the last period of dryness and consumption, or thirst appears from the thirst-inducing bite of poisonous snakes; When these snakes bite someone, the person who is bitten drinks all the time, not being able to quench his thirst, until he dies. The same thing happens from drinking wine in which snakes have died, or from eating the same food.
Sometimes thirst appears when you have a bowel movement with laxatives or excessive diarrhea. A person who drinks a laxative usually experiences thirst when the drug's effect wears off, the absence of which most often indicates that the drug is still working. It sometimes happens that thirst lags behind the allotted time, but it also happens that it comes sooner, before the medicine takes effect. The premature appearance of thirst occurs either as a result of the warmth of the medicine, or as a result of the warmth and dryness of the stomach, and it is delayed due to the opposite reasons. Therefore, thirst in a person with a hot and dry stomach, who drinks a medicine that is hot by nature, does not indicate that the medicine has had its effect, but thirst with the opposite properties proves that the medicine has had its effect some time ago. Among the causes that excite thirst are the need to talk a lot, long physical exercises, fatigue and sleep after foods that are hot by nature; if the food was not hot, then sleep calms thirst. When, during acute illnesses, there are simultaneously signs of extreme thirst and extreme dryness, this is one of the worst signs.
Signs. As for the signs of thirst arising due to various states of nature, they are already known from what is said in the general sections, and nature can be with matter or without any matter, bitter or salty, with the properties of bavrak, or sweet, or causing harm by its fermentation. As for the signs of thirst arising from blockages, sometimes the softness of nature indicates it. A sign of thirst due to diabitis is that thirst is not relieved by drinking water; on the contrary, when the patient drinks water, it causes urine to be expelled, and thirst returns. Thus, thirst and urination are mutually equal and follow each other, completing a circuit. A sign that thirst arose from the mentioned causes that excite it is the previous presence of these causes.
Signs of thirst arising from the participation of other organs. As for thirst due to the complicity of the lungs or the heart, it is calmed by a cool breeze; Insomnia helps with such thirst, and sleep intensifies it. Often, drinking water a little more effectively calms such thirst than drinking it in one gulp in large quantities. On the contrary, drinking in one gulp sometimes causes the excess to congeal, then warms it and increases thirst many times over. Attempts to suppress thirst only intensify it, and the patient no longer benefits from what helped him at first. Thirst arising from dryness of the esophagus is weak and mild; It helps with sleep, which moisturizes the inside of the body, as well as rest and abstinence from talking. Staying without sleep helps relieve thirst caused by a hot stomach. If thirst occurs due to the complicity of the liver, then this is indicated by examination of the condition of the liver and the discovery of a hot, dry nature or the presence of a tumor, hot or not.
Treatment. All types of causes of thirst, depending “on nature, are treated with what is opposite to such nature. Thirst arising from the lungs is treated with a cool breeze; thirst is often calmed by wetting the tongue with cold water. Those who are afraid of thirst during fasting should use horse broth instead of beans and chickpeas vinegar with olive oil and avoid beans and chickpeas, because they excite thirst. A sick person undergoing a bowel movement should endure the thirst caused by a bowel movement until his digestion is strengthened. The thirsty person should not drink a lot of wine or very cold water at once; then the faint warmth of his stomach dies, weakened by thirst. Vomiting sometimes causes thirst, which is calmed by apple wine with rose water. Cold water calms the thirst of a hot and dry stomach, and a stomach with a salty juice, and hot water often calms his thirst. If the thirst is strong and there is no fever, then a little julab should be mixed with the water, which brings the water to the most distant organs.As for the blow, push and fall on the stomach area, here is a medicinal bandage that is useful for this: take Syrian apples with a pleasant smell, boiled in wine until completely softened, and finely pound; Fifty dirhams of these apples are taken and mixed with ten dirhams of incense, eight dirhams of roses and six dirhams of sabur; all this is tied with the squeezed juice of plantain and cypress leaves, iris oil is added, heated and a bandage is tied on the stomach in the place where the stomach is located for several days.
