What is irritable bowel syndrome?

Irritable bowel syndrome (IBS) is an increasingly common disorder that involves the large intestine. Symptoms of IBS include abdominal cramping and pain, bloating and gas, and diarrhea or constipation or both. It’s a chronic condition, so while your symptoms may vary in severity, they can disappear for weeks or months, or remain fairly constant.

There are three types of IBS. They all have abdominal symptoms such as cramping and bloating, but they vary according to the consistency of your stools:

  • IBS-D, which is accompanied by diarrhea
  • IBS-C, which brings on constipation
  • IBS-A, which is also known as IBS-M (mixed type) because it causes stools that alternate between diarrhea and constipation.

What are the risks associated with IBS?

Fortunately, IBS does not increase your risk of colorectal cancer. There is controversy in this field, however, and some theorize that IBS may be on a continuum with ‘leaky gut’ (gut lining integrity compromise) and dysbiosis, thus possibly contributing to food sensitivities and hyperresponsiveness of the immune system. Regardless, persistent IBS symptoms can greatly interfere with your quality of life. It can make you miss work or skip social activities. Many people with IBS also say the discomfort can bring on depression and anxiety, which then worsens the symptoms of IBS.

What causes IBS?

The intestinal walls are lined with layers of muscle that contract to move food through your digestive system. Stronger-than-normal contractions can cause gas, bloating, and diarrhea. Weaker intestinal contractions may slow food passage and cause hard, dry stools.

Inflammation in the intestines caused by an increased number of immune-system cells may also result in abdominal pain, diarrhea, and other symptoms of IBS.

IBS can emerge after a severe bout of infectious diarrhea (gastroenteritis) caused by a bacterial or viral infection. Bacterial overgrowth in your abdomen can also bring on IBS symptoms. And sometimes, IBS strikes by reducing the "good" bacteria that live in your intestines.

Other things that might trigger or worsen IBS symptoms include:

  • Certain beverages or foods, including wheat, dairy products, and carbonated drinks
  • Periods of increased stress
  • Hormonal changes or fluctuations during your menstrual cycle, with women twice as likely as men to develop IBS

How does Dr. Leong treat IBS?

Dr. Leong will complete a detailed evaluation of your symptoms and your health status before deciding on treatment options. She may recommend dietary changes, stress reduction, or further diagnostic studies to uncover the root cause of your digestive distress.
