Irritable bowel syndrome (IBS) is a widespread condition that obstructs the regular function of the colon's large intestine (colon). The University of Maryland Medical Center (UMMC) says up to 20 percent of the population will have IBS at some point. The syndrome frequently starts in adolescents or early adulthood and is commonly linked to stress. There are a number of neurological symptoms (the network of nerve cells and nerve fibers in most animals that conveys sensations to the brain and motor impulses to organs and muscles) associated with IBS.
Psychological Effects
According to UMMC, more than half of the people with irritable bowel syndrome have psychological symptoms. Low levels of the neurotransmitter (brain chemical) serotonin have been identified in individuals with IBS.
The National Digestive Diseases Information Clearing House (NDDIC) says in addition, people who suffer from IBS often report feelings of depression and anxiety. Some individuals may have panic attacks and problems sleeping.
Stress & IBS
The NDDIC says the colon has several nerves that are linked to the brain. During periods of tension or trauma, the contractions of the colon lead to abdominal distress. As with the lungs and heart, the colon is partially managed by the autonomic nervous system, which reacts to stress.
Feeling overwhelmed, anxious, angry or upset may provoke colon spasms (involuntary and sometimes painful muscle contractions) in people with IBS.
Stress makes the mind more aware of the sensations that arise in the colon, making the person perceive these sensations as unpleasant.
The Immune System & IBS
According to the NDDIC, there is evidence to indicate that IBS is impacted by the infection-fighting immune system in the body. Since the immune system is affected by stress, people with IBS should learn stress management techniques as part of their overall treatment for the condition. This may include meditation, exercise, counseling and getting sufficient sleep.
Phyisical Symptoms
Some of the common physical signs of IBS are abdominal discomfort or pain, bloating, gas, diarrhea and/or constipation and mucus in the stool. There may also be a feeling that a bowel movement is incomplete.
