Disease is that condition of the body where there is any departure from the normal, in function or structure. It may be local or general, and may tend to recovery, death or life-long suffering.
Many so-called forms of dyspepsia are brought about by improper eating, or by eating when not hungry or when tired. In such cases, a regulated life and the right selection, combination and preparation of foods is the only means to correct it.
Causes: After effects from acute diseases, worry, envy, excesses of eating or drinking, bony displacements, anemia and overwork. The patient should consult a physician at once. If certain areas of the glandular structure of stomach or intestine have been destroyed once, the normal structure cannot be restored; but with good care and proper dietetic measures great improvement can take place. Excess of starchy foods is always harmful. Particles of food not well masticated can cause much disturbance. The presence of fats in large amounts or wrongly combined with other foods will also retard digestion; they cause the pyloric orifice to contract more, and leave the food contents in the stomach for a long time, and in this way cause fermentation and putrefaction.
Dyspepsia and indigestion are the beginnings of a disordered metabolism and if neglected the results are: Nervous prostration, insanity, consumption,, pelvic disorders, difficult child-birth, weak offspring, different forms of tumors and cancers and a multitude of fashionable and epidemic diseases.
The recognized rule is that the bowels should be evacuated once per day. Nevertheless, there are a number of people whose bowels act only every second or third day, and whose health is not impaired thereby. Healthy people who live on natural foods, such as raw fruits, nuts and grains, or on simple cooked foods with a moderate amount of meat, as a rule will not find it necessary to resort to artificial means for evacuation of the bowels.
People, whose diet consists mainly of meats, cooked vegetables and potatoes mixed with fermentable substances, or those who mix meat with milk and sweets or soft puddings will find it absolutely necessary to have a daily evacuation of the bowels, in order to retain perfect health.
Different habits of diet have a great effect upon evacuations. People who suffer from chronic constipation without any particular ailment or disease may often be greatly benefited by adding a greater amount of fruits or vegetables to their diet. Others find it necessary to discard cooked fruits for a while and take oily substances. Some people are constipated from insufficient protein elements in their food. The original cause may have been mechanical obstruction. Morbid anatomy and morbid physiology go hand in hand. Therefore, if proper hygiene and diet does not correct the condition, the patient should consult a physician for special treatment.
