Even the most obstinate constipation not dependent on structural lesion of the intestines, can generally be relieved by thorough rational treatment. In the first place, all the causes of the disease must be carefully avoided. If the patient's habits have been sedentary, he must take abundant exercise by walking, riding, etc. Horseback riding is particularly useful in this disease. Another excellent measure in such cases is vigorous kneading and percussing of the abdomen several times a day for five or ten minutes at a time. Many obstinate cases of constipation have been cured by this means alone. Eating an orange before breakfast, or drinking a glass or two of cold water, are simple measures which have sometimes proved effective. The diet should be carefully attended to. Unless there is some disease of the stomach, such as ulcer or painful dyspepsia, coarse food should be used. Very little animal food should be taken. The diet should consist of fruits, unbolted meal, or grains. A regular time should be appointed to relieve the bowels, whether there is any inclination or not. The time at which movement is most likely to be secured is after breakfast. With some persons, however, the movement occurs immediately upon rising. Hot applications to the abdomen, the use of alternate hot and cold applications to the lower part of the spine, the employment of the abdominal girdle, and cool sitz baths daily, or every other day, are measures of great value in the treatment of this condition. In the treatment of obstinate cases, we have often secured great benefit by the employment of electricity and Swedish Movements. Electricity should be applied directly to the bowels sufficiently strong to occasion slight contraction of the abdominal muscles. When the patient has been for a long time dependent on laxatives of some sort, enemata of tepid water should be substituted while the effect of remedial measures of a more radical character is being obtained. The bowels should not be allowed to move when the contents have become hardened by long retention without taking large enemata. In very bad cases the patient will find great relief by evacuating the bowels while sitting over a vessel filled with water as warm as it can be borne. By means of the simple measures mentioned above we have relieved cases in which there has been no natural movement of the bowels for from ten to twenty years, the patient having been wholly dependent upon cathartics.
