9 The most common symptom of IBS (Irritable Bowel Syndrome)

Rate this post

Irriteble bowel syndrome (IBS) is a common digestive disease that affects the work of the large intestine, which is characterized by abdominal pain and changes in bowel habits. Diet, stress, lack of sleep, and changes in intestinal bacteria can trigger symptoms. However, triggers are different for everyone, so it is difficult to mention specific foods or stress that everyone should avoid. Then, what are the most common symptoms of IBS?

The most common symptoms of IBS

1. Abdominal pain and cramps

 causes of abdominal cramps

Abdominal pain is the most common symptom of IBS. Normally, the intestines and brain work together to control digestion, through hormones, nerves, and signals released by good bacteria that live in your intestines.

However, IBS signals are not well received, causing the muscles of the large intestine to tense and not coordinate well.

This pain usually occurs in the lower abdomen or the entire abdomen, and rarely occurs only in the upper abdomen. This pain usually subsides after you have defecated.

2. Diarrhea

Diarrhea is a dominant symptom of IBS occurring in about one third of patients. A study showed that IBS patients experienced an average of 12 bowel movements per week.

The digestive process in the intestine is faster, often leading to an impulse for sudden bowel movements.

In addition, feces from IBS patients tend to be runny and may contain mucus.

3. Constipation

In addition to causing diarrhea, IBS can also cause constipation. IBS that is predominantly constipated is a more common symptom of IBS, which affects nearly 50 percent of people with IBS.

Signals that change between the brain and intestines can speed up or slow down the time of fecal formation. When this formation time slows down, the intestine absorbs more water from the feces, so that the stool becomes more difficult to remove.

4. Constipation and diarrhea (mixed)

Constipation, diarrhea, or both take place in about 20 percent of IBS patients. Diarrhea and constipation in IBS cause recurrent chronic abdominal pain.

IBS with these two symptoms tends to be more severe than others with more frequent and intense symptoms.

5. Changes in bowel movements

Movement of slowing stools in the intestine often dehydrates when the intestine absorbs water. Thus making stools become hard which can worsen constipation symptoms.

While fast stool movement through the intestine leaves little time to absorb water, so the stool becomes more fluid and causes diarrhea.

IBS can also cause mucus to accumulate in the feces, which usually not associated with other causes of constipation.

In addition, feces may also contain blood. This is a symptom of IBS that is potentially more serious and needs to be seen immediately by a doctor. Blood in the stool may appear red but often appear darker or black.

6. Belly and bloated stomach

Digestive changes in IBS cause more gas production in the intestine and cause flatulence.

In a study of 337 IBS patients, 83 percent reported experiencing flatulence and cramps. Both of these symptoms are more common in women and in IBS which is predominantly constipated or a mixed type of IBS.

7. Food intolerance

 allergies and food intolerance

This food intolerance is not allergic. Some people with IBS report that certain foods can trigger IBS symptoms. However, the reason why certain foods can trigger IBS is unclear.

IBS-triggering foods are also different for everyone. However, the most frequent include FODMAP, lactoa, and gluten.

8. Fatigue and insomnia


A study reported that 160 adults diagnosed with IBS had low stamina, so they felt tired quickly. IBS patients are more limiting physical activity in work and social interaction.

IBS is also associated with insomnia, which includes insomnia, frequent waking, and feeling uncomfortable in the morning when I wake up.

In a study of 112 people adults with IBS, 13 percent reported poor sleep quality.

Another study of 50 men and women found that people with IBS slept about an hour longer but felt less refreshed in the morning than those who did not have IBS.

In addition, these two symptoms of IBS can also indicate worse gastrointestinal symptoms.

9. Anxiety and depression

Other symptoms of IBS are anxiety and depression. It is unclear whether this symptom is an expression of mental stress or life stress with IBS that makes people more susceptible to psychological disorders.

A study conducted on 94,000 men and women, people with IBS more than 50 percent had anxiety disorders and more than 70 percent more likely to experience mood disorders, such as depression.

Other studies compared levels of stress hormone cortisol in patients with and without IBS. As a result, people with IBS experience higher cortisol changes, which means a higher level of stress.
