Are ulcerative colitis and crohn's disease hereditary?

Somewhat: There are numerous families where there are children and /or grandchildren, cousins, etc. With these diseases. If both parents have ibd, the incidence is around 50% in the kids. Otherwise about 20% of patients will have a first degree relative with ibd. So you do the math! it isn't exactly hereditary, but there a familial incedence. By the way, the kids of colitis patients often have crohn's.

Yes: Although many patients can be diagnosed with crohn's disease or ulcerative colitis without a family history, up to 10% of patients will have a mother or father with the disease.

Not really: There is a genetic component and risks for ibd are higher in those witha family history. However there are a multitude of other contributing factors.

Genes+environment : A combination of genetic predisposion (for example Crohn's is more common in ashkenazi jews), life events (eg appendectomy increases one and decreases the other), and environmental influences (eg smoking increases Crohn's and decreases severity of uc...). Bet you didn't expect the latter! as knowledge increases more precise factors are identified.

UC: Question as to which is more serious, Crohn's or Ulcerative Colitis, misses the point that these are different intensities of disorder along a spectrum of manifestation wherein intestinal smooth muscle function is hyperdynamic due to neurologic autonomic system impingement & over-stimulation. Ulcerative Colitis represents greater intensity of these dysfunctions; involving inflammation & bleeding.

Quick summary: Ibs is irritable bowel syndrome. It causes chronic abdominal discomfort with changes in bowel movements. Ibd is inflammatory bowel disease, for which ulcerative colitis and crohn's are the two main subtypes. These are characterized by chronic inflammation of the bowel, and can often have diarrhea, blood in the stool, weight loss, fevers, arthritis, vomiting, and (with crohn's) bowel obstruction.
