NAUSEA-AND-VOMITING

‘Nausea’ is uncomfortable sensation that a person gets in the region of the chest, abdomen and sometimes in the head, which progresses to vomiting when the digestive tract sends signals to inform the centres in the brain that certain harmful substances are present in the stomach. This sensation of nausea is better after the patient vomits. Regurgitation or throwing up of the contents of the stomach is termed as ‘vomiting’. Vomiting is sometimes the body’s own reflex action to throw out some harmful products taken in, but in cases where the vomiting persists for more than a few days or in cases where the vomiting occurs after a head injury or in cases where the vomiting is of a black color, it is better to consult a doctor immediately.

Nausea and vomiting in the initial months of pregnancy is normal, but if it persists for a long time and if the frequency of vomiting is more, it is necessary to consult a doctor immediately. Bad sights, bad smalls and bed sounds can sometimes initiate nausea and vomiting. Anxiety, dietary indiscretions, some drugs, alcohol, motion sickness and some illnesses (like gastroenteritis, hepatitis, urinary tract infections, gastric cancer, peptic ulcers, appendicitis, cholecystitis, pancreatitis, intestinal obstruction, migraines, etc.) can also cause it. ‘Retching’ can result when the brain’s vomiting orders continue even after the stomach is completely empty.

The patient is asked to take in a lot of fluids in the form of electrolyte water, soups, juice, etc; which should be sipped slowly to let the irritated stomach adjust. Do not force the patient to eat anything since that will only increase the problem. Once the vomiting subsides the person can start off with a gelatin desert or other bland foods like nonbuttered toast or crackers.
