Irritable bowel syndrome, or IBS, is a disorder of the digestive tract that results in muscle spasms, pain, gas, bloating and irregular bowel movements. Its cause is largely unknown, but it is suspected that muscle sensitivity and brain connections to the gut play a role in the symptomatology. Senna is an herb that is often used as a stimulant laxative for people suffering from constipation. Its use is suggested in IBS for the treatment of constipation. However, it should be done so with caution. Check with your doctor before using senna for IBS.
Irritable Bowel Syndrome
Irritable bowel syndrome is a gastrointestinal disorder in which you experience pain and muscle spasms in the abdomen. Sufferers often experience difficulties with bowel movements as well. Though no specific cause is known, it is suspected that various factors increase your risk of developing the disorder. It is thought that while the intestines themselves are not damaged, the muscles may have some difficulty responding to pain, sensitivity and movement. Additionally, stress may exacerbate symptoms by leading to increased spasms, suggesting the importance of the connection between the brain and the intestinal tract. IBS may also develop after an infection.
Symptoms and Diagnosis of IBS
Common symptoms found in individuals with IBS include muscle spasms, abdominal pain, bloating, gas and irregular bowel movements. Individuals typically experience either predominant constipation or predominant diarrhea, but some people fluctuate between the two. Diagnosis of the disorder tends to occur in early adulthood and is more commonly found in women. There is no single test that can indicate the definitive presence of IBS, but rather a series of tests must be done to rule out alternate possibilities. Your doctor may perform a blood test, stool culture and colonoscopy.
Senna
According to Medline Plus, a National Institutes of Health website, senna is a natural herb whose leaves and fruit can be used in the treatment of constipation. It is used as a type of stimulant laxative that increases motility in the intestines, encouraging bowel movements. As a medication, it is available over the counter. The chemicals contained in senna, known as senosides, work by irritating the intestinal wall. This results in contractions of the lower intestines, which pushes out the material in them. According to Drug Digest, senna also keeps water present within the intestines, which helps make stool softer and pass more easily. The typical dosage for adults is 17.2 mg per day, not to exceed more than 34.4 mg per day. There is concern that if senna is used for longer than two weeks, your bowels may not function normally on their own.
Efficacy and Uses of Senna
According to the Natural Medicines Comprehensive Database, senna is considered effective for the alleviation of constipation and for clearing the intestines before a colonoscopy. It is reportedly used in the treatment of IBS. The ability to benefit people suffering from constipation indicates its usefulness for people with IBS with constipation. It is suggested that senna is not suitable for long-term use by women who are pregnant or breastfeeding, but likely is safe for short-term use. Additionally, the use of senna by people with gastrointestinal disorders, such as Crohn's disease or ulcerative colitis, is not recommended. Possible drug and herbal interactions should also be considered. Consultation with a doctor is critical before the use of senna. The evidence of its effectiveness for IBS is limited and warrants further study.
