Among the secondary symptoms of proctitis and colitis is poisoned blood--anemia, which is usually followed by impaired nutrition and emaciation or obesity. Along with the changes in the blood and nutrition there occurs lodgment or deposit of salts, acids, etc., in the various organs and tissues of the body. Almost every one is familiar with gouty deposits in the finger joints and other joints of the body. If the deposits occur in the muscular tissue it is called rheumatism. If in the urinary organs we have gravel, Bright’s disease, diabetes, cystitis, irritation of the neck of the bladder, frequent calls to urinate; and the urine, scanty and high-colored, on cooling reveals a crystalline deposit. The principal mineral substances of the urine are as follows--of which one or more may become poisonous: chloride of potassium, chloride of calcium, chloride of magnesium, chloride of sodium, sulphate of potassium, sulphate of soda, sulphate of magnesia, phosphate of soda, and phosphate of potassium. The liver gets its share of the foul substances generated in the intestinal canal, which cause congestion of the organ. Toxic biliary salts and acids are present. The deposit may form gall-stones, and jaundice and many other annoying symptoms may occur. The system is simply a filter, or blotter, that lets the poisonous contents of the intestinal canal pass through and out; but all the organs and tissues, during the process, retain many of the foreign toxic substances, which overtax (and frequently destroy) their functions with work that Nature never intended they should do. Think of it--all the organs and tissues around the intestinal canal serving as _fecal vents_! Deposits cause irritation of nerve centers and nerve cells precisely as in fibrous and cartilaginous tissues; and we speak of the symptoms as spinal irritation, hysteria, chorea, lumbago, sciatica, nervous tension, headache, irritability, despondency, melancholia, insomnia, dementia, etc. From the disturbance of the voluntary and involuntary nerves we have irregular circulation of the blood from disturbed heart action, cold hands and feet, and flushing of the face alternating with pallor, vertigo, and dizziness. The capillary circulation becomes obstructed with crystallized bodies, as chunks of ice obstruct a stream of water. Catarrhal inflammation of the mucous membrane is set up in various parts of the body by the deposits in the membrane and the abnormal means of their elimination through it. The skin of the body, which is the mucous membrane turned outward, suffers likewise from diseases having numerous names.
