People who have suffered from constipation have most likely heard of senna, especially if they've read the back of a laxative box. While not all bowel stimulators include this botanical ingredient in their formula, it is known to be an effective method of treating occasional constipation. Yet, it does pose some problems for some people, namely when taken for an extended period of time.
Identification
Senna is basically a natural herb that is used to stimulate the bowels. It is found in a number of commercial laxatives, such as Fleet Natural, Goldline, Swiss Kriss and Senokot Tablets, used to remedy constipation. While you may not see the herb listed in the list of ingredients, it could still be present, as the leaves of the senna are used to produce sennosides, another common ingredient in stimulant laxatives. Sennosides are found in the formulas of Ex-Lax, Senna Soft and Senokot Liquid.
How It Works
Any laxative that contains senna will essentially interact with the bacteria found in your digestive track. This interaction will then cause a contraction within your intestines, producing a bowel movement between 6 and 12 hours after you've taken the supplement. Of course, this is only true when the laxative is used as described on the packaging. Taking more than the suggested amount may cause a or even diarrhea in less time.
Recommendations
Currently, the Food and Drug Administration has given senna the classification of "undefined safety," which means that it is thought to be safe, but its effects are still indeterminate. For the average adult, senna should be used only for limited lengths of time as recommended, typically not to exceed four tablets in a 24-hour period and to be used for no longer than 1 week. Using senna for longer periods of time could cause a dependency on the substance and make it possible to have a bowel movement only while using the supplement.
Side Effects
As with any supplement, a laxative containing senna does have some side effects, including nausea or vomiting, diarrhea and abdominal cramps or gas and bloating. While not seemingly severe, you should stop taking senna if you find these side effects worsening or persisting for an extended period of time. Though most of the people encounter while using senna are minor, some people have complained of more significant symptoms, including bloody stools, rectal bleeding, dizziness or lightheadedness, mild to moderate fatigue and even a rapid heart rhythm. Again, you should immediately cease use and contact your doctor.
Weight Loss
There has been some talk about the use of senna (or any laxative) as a tool to lose weight. Besides the negative effects on a person's health, such as low potassium, malnutrition, dehydration, osteomalacia (bone damage), moderate to severe fatigue and intestinal damage, usage doesn't change your caloric intake. It is only ridding your body of excess water, which can also displace the balance of your electrolytes. Using laxatives is not recommend as part of any weight-loss regimen.
