Nausea,Vomiting and Digestion



What causes disorder of the digestion system and how to treat it?

Nausea and vomiting are not exclusive to disorders of the digestive system. They can also occur in some neurological conditions, especially where the inner ear and its balance functions are impaired, or where pressure inside the skull becomes raised. Endogenous poisoning due to the accumulation of excess waste products, such as occurs in kidney failure, may also be responsible.

When some of the symptoms are caused by disorders in the gastrointestinal tract, the precipitating abnormality will usually be found in the upper part, such as the oesophagus (gullet), stomach, duodenum, or gallbladder and its ducts.

In the oesophagus the two most likely problems are obstruction and irritation. When obstruction occurs, food becomes difficult to swallow, and can be felt to stick behind the breastbone, and may be regurgitated or vomited. When irritation is the main problem, the vomiting is likely to be associated with pain-particularly heartburn, where acid can be felt rising up into the throat. This sensation is, in fact, usually due to acid being allowed to rise up out of the stomach and hence irritate the sensitive lining of the gullet. A defect at the junction of the oesophagus and stomach is the usual cause and this is called a hiatus hernia.

Both of these symptom complexes-regurgitation and food that sticks, and vomiting with heartburn-normally need to be investigated. The technique used in the first instance is a barium swallow, where in this test the patient swallows a radio-opaque substance and its progress down the gullet can be observed on X-rays. Thus the site of the abnormality can nearly always be identified without difficulty, although there may be problems in establishing its nature for certain. Where there is doubt it will be necessary to arrange for the lesion to be seen directly; this can be done by the use of a narrow, flexible telescope (fibrotic endoscope), and even more usefully a small piece can be removed by the instrument. Close microscopic examination can then be undertaken and the precise nature of the problem determined. This course of action is necessary when it is feared that an obstructing lesion is due to a cancerous growth. When such a serious diagnosis has been confirmed, its treatment will depend on the exact site and extent of the growth, the choice lying between radiotherapy to shrink the growth, its removal by surgery, or a bypass by a surgically inserted tube. Simple, benign obstructions can sometimes be easily stretched-although this procedure may need to be repeated at regular intervals.

A hiatus hernia is an inconvenient defect but rarely serious, and surgical intervention to correct it is rarely required. Much symptomatic improvement can be obtained by simple measures such as weight loss-where there is obesity-avoidance of stooping and straining, and the regular use of preparations to neutralize or reduce acid secretions. A hiatus hernia is found in about 60 per cent of all people over the age of 60 years, and most of these (three-quarters) do get some symptoms (usually heartburn).
