  IBS is a functional bowel disorder of the gastrointestinal (GI) tract characterized by recurrent abdominal pain and discomfort accompanied by alterations in bowel function, diarrhea, constipation or a combination of both, typically over months or years.  A diagnosis of IBS has been reported by 10 to 20% of adults in the United States, and symptoms of IBS are responsible for over 3 million yearly visits to physicians.  Research suggests that IBS is one of the most common functional GI disorders.  IBS exhibits a predominance in women, with females representing over 70% of IBS sufferers.

A combination of treatments may help a sufferer cope with the symptoms  These include stress, dietary, lifestyle changes and perhaps the introduction of medications.
Crohn's disease is a chronic, episodic, inflammatory condition of the gastrointestinal tract characterized by affecting the entire wall of the involved bowel or intestines. It can affect any part of the gastrointestinal tract from mouth to anus. Crohn's disease can also cause complications outside of the gastrointestinal tract such as skin rashes, arthritis, and inflammation of the eye.

Treatments include medications to reduce inflammation or to suppress the immune response.  Some patients may require surgery.
Ulcerative colitis is a form of colitis, a disease of the intestine, specifically the large intestine or colon, that includes characteristic ulcers, or open sores, in the colon. The main symptom of active disease is usually diarrhea mixed with blood, of gradual onset.

Ulcerative Colitis is treated by medications with the aim to maintain remission.  Some patients may require surgery.
Gastroesophageal Reflux is a condition where the lower esophageal sphincter (the muscular ring at the lower end of the esophagus) is abnormally relaxed and allows the stomach's acidic contents to flow back or 'reflux' into the gullet (esophagus). It can also cause heartburn. It is a common condition and one of the most frequent causes of indigestion.

Anyone, including infants and children, can have GERD. If not treated, it can lead to more serious health problems. In some cases, you might need medicines or surgery. However, many people can improve their symptoms by

  • Avoiding alcohol and spicy, fatty or acidic foods that trigger heartburn
  • Eating smaller meals
  • Not eating close to bedtime
  • Losing weight if needed
  • Wearing loose-fitting clothes
Celiac disease is both a disease of malabsorption—meaning nutrients are not absorbed properly—and an abnormal immune reaction to gluten. Celiac disease is also known as celiac sprue, nontropical sprue, and gluten-sensitive enteropathy. Celiac disease is genetic, meaning it runs in families. Sometimes the disease is triggered—or becomes active for the first time—after surgery, pregnancy, childbirth, viral infection, or severe emotional stress.

Adults are less likely to have digestive symptoms and may instead have one or more of the following:
  • unexplained iron-deficiency anemia
  • fatigue
  • bone or joint pain
  • arthritis
  • bone loss or osteoporosis
  • depression or anxiety
  • tingling numbness in the hands and feet
  • seizures
  • missed menstrual periods
  • infertility or recurrent miscarriage
  • canker sores inside the mouth
  • an itchy skin rash called dermatitis herpetiformis
