Alcohol must not be taken and coffee and tea must be limited in strength and quantity.
Active exercise must be practiced daily and full elimination secured from the bowels.
The person afflicted with gall-stones must not sit too long or in a cramped position.
The presence of fat in the duodenum increases the flow of pancreatic juice which, in turn, stimulates the flow of bile, so olive oil is often recommended in case of gall-stones. It is questionable whether it is of benefit, because, as stated, much fat upsets the liver.
Watch the water supply. Hard water which contains lime should be boiled to precipitate the calcium.
DERANGEMENTS OF THE KIDNEYS
The office of the kidneys is to eliminate from the system certain nitrogenous elements in solution; the work of the kidneys, in most conditions, is aided by copious drinking of water.
The influence exerted on the function of the excretory organs by the components of the food has not been given the attention it merits.
If the fluids are not taken in sufficient amount and much animal food is eaten, the urine becomes more concentrated and may irritate the kidneys or the bladder and give rise to calculi (kidney stones) or to the deposit of uric acid. Watery vegetables, juicy fruits, milk, water, and most beverages, by increasing the output of urine, lessen its acidity and density.
A diet limited to certain articles of food by the likes or dislikes of the individual, as the starches and sugars, too large consumption of acid fruits or too fatty foods may cause the appearance in the urine of abnormal amounts of various substances, as sugar, phosphates, calcium oxalate, or fatty acids.
