Irritable Bowel Syndrome Q & A

What is IBS?

IBS is a gastrointestinal disorder that causes symptoms like chronic constipation, diarrhea, or both. It's called a functional disorder, which means it's related to gut dysfunction rather than structural problems. 

IBS isn't a cancer or a precancerous condition, and it's not an early indicator of other gastrointestinal disease. But, that doesn't mean it's not a serious and frustrating problem. Fortunately, IBS isn't something you need to live with. Dr. Hussain at Northside Gastroenterology Associates can help you cope with IBS so you don't have to continue suffering with the uncertainty and frustration of its chronic symptoms.

What are the types of IBS?

There are three general classifications for IBS.

IBS with constipation

IBS with constipation commonly causes chronic constipation, bloating, and abdominal pain, but doesn't usually cause diarrhea.

IBS with diarrhea

IBS with diarrhea causes diarrhea, urgent need to defecate, and abdominal pain, but doesn't usually cause constipation.

Mixed IBS

Mixed IBS causes both constipation and diarrhea with all their associated symptoms. 

It's important to describe your symptoms to Dr. Hussain as clearly as possible so he can diagnose the type of IBS and design the right treatment plan.

How is IBS diagnosed?

Dr. Hussain reviews your symptoms carefully, and also performs a physical exam. He typically conducts blood tests as well. If your symptoms suggest other conditions, Dr. Hussain may perform a colonoscopy, a test in which he views your rectum and colon through an ultrathin tube. In certain cases, Dr. Hussain may also perform a biopsy to rule out other inflammatory bowel problems.

What causes IBS?

The cause isn't certain at this time. Medical research suggests that IBS sufferers might have a particularly sensitive gastrointestinal tract that works either faster or slower than normal. 

How is IBS treated?

IBS treatment often starts with changes in your diet and lifestyle.

  • Eating less gas-producing foods
  • Limiting gluten intake
  • Eating slowly
  • Avoiding overeating
  • Adding dietary fiber to your diet
  • Adding probiotics to your diet
  • Practicing relaxation techniques


If these changes don't help with IBS symptoms, Dr. Hussain can prescribe medications created specifically for IBS, if needed. Some options include Alosetron (LotronexⓇ), Eluxadoline (ViberziⓇ), or Rifaximin (XifaxanⓇ) for IBS with diarrhea and Lubiprostone (AmitizaⓇ) or Linaclotide (LinzessⓇ) for IBS with constipation.
