Electrolyte water is too much to drink and can be replaced with other bowel cleansing medications. A colonoscopy can also be attempted when the bowel is not adequately prepared, but a large amount of fecal matter remaining in the bowel will seriously affect the operation and observation of the examiner, greatly reducing the lesion detection rate.
It is recommended that the patient can be taken orally in divided doses, with the help of a straw, electrolyte water slightly cooled to reduce the odor, blended with some sugar water or under the guidance of the doctor in advance of the oral antiemetic to help take, such as still intolerant, can be replaced with other intestinal cleansing medication, can also be used with soapy water and saline enemas, but the effect of the enema is not as thorough as the effect of oral intestinal cleansing of electrolyte water can only be used as a remedial measure.
It should be noted that do not unauthorized use of mannitol bowel cleansing, because mannitol in the process of bowel cleansing will produce methane, methane is a flammable gas, in the electrocutaneous treatment is prone to induce an explosion, resulting in serious consequences.
If you feel unwell during the colonoscopy, feedback to your doctor promptly.
