Crohn’s Disease Symptoms

Although Crohn’s disease isn’t as prevalent as ailments such as diabetes and asthma, it still afflicts more than 700,000 people. If you’re a young adult between the ages of 15 to 30, there’s an even greater chance of you experiencing Crohn’s disease.

Unfortunately, scientists have yet to find a cure for this condition. If medication and diet changes fail to reduce the inflammation, gastrointestinal surgery is usually the next approach. Roughly 70 percent of the people suffering from Crohn’s disease will eventually need surgery.

What is Crohn’s Disease?

Crohn’s disease shares many similarities with colitis, which is also a serious inflammatory bowel disease. While colitis is typically limited to the colon, Crohn’s disease can affect different areas of the digestive tract. Despite the fact that Crohn’s disease often occurs in the colon and the small intestine, it can also impact your mouth and anus.

While a great deal of research has been done on Crohn’s disease, experts still haven’t pinpointed a definite cause. However, certain factors can contribute to the illness.

When suffering from Crohn’s disease, it’s believed that the immune system mistakenly attacks the good bacteria. This eventually causes chronic inflammation and thickening of the intestinal wall. On the other hand, a study in the Journal of Clinical Microbiology indicates a specific type of bacteria triggers Crohn’s disease.

Cigarette Smoking

Like so many other health ailments, Crohn’s disease has been linked to cigarette smoking. People who continue to smoke after being diagnosed with Crohn’s disease are more likely to experience flare-ups. Furthermore, smoking can decrease the effectiveness of medication.
