Enemas, such as the well-known Fleet enema, treat constipation by introducing fluid into the intestines through the rectum. The liquid softens impacted stool, while the enema nozzle loosens the rectum. That combination will stimulate a large bowel movement. Constipation Relief: Types of Enemas Nearly all enemas for constipation use a blend of water and some other substance that helps dissolve or lubricate impacted stools as well as keep the intestines from absorbing the water. Some of the most commonly used enemas are:
Drink one or two glasses of water prior to the enema, as it can cause you to become dehydrated.Lie on your stomach with your knees pulled under you.Lubricate the enema tube and gently insert it into your rectum.If you’re using a disposable enema, gently squeeze the contents into your rectum. If you’re using an enema bag with a homemade solution, hold the bag up and allow gravity to deliver the contents.Once the bag is empty, remove the tube from your rectum.Wait in that position until you feel the need to move your bowels. You should feel a powerful urge within 2 to 10 minutes. Try to hold the enema in for at least 5 minutes to achieve maximum benefit.
Health Concerns Regarding Enemas Because enemas can cause dehydration, overuse of enemas can create serious health problems. Use of enemas for constipation on a regular basis can lead to an electrolyte imbalance in the body called hyponatremia, in which the blood becomes diluted and its salt content becomes lower than normal. Hyponatremia can cause muscle spasms and swelling of the brain that leads to mental impairment. This is a particular concern when using enemas with plain tap water. On the other extreme, overuse of phosphate enemas for constipation can lead to a condition called hyperphosphatemia, in which the blood levels of phosphate salts become elevated. Be sure to consult with your doctor before using an enema, and exhaust all other possibilities first. Learn more in the Everyday Health Digestive Health Center.
