Severe abdominal pain?


Hello, doctor.
This morning, while I was lying in bed, I suddenly experienced severe abdominal pain (I was lying on my side at the time), accompanied by loud bowel sounds and a slight urge to use the restroom.
After using the restroom, I felt somewhat better.
The stool was loose, but I have a history of irritable bowel syndrome, so I'm not sure if that's why my stool was loose.
I'm a bit concerned that there might be an issue with my gastrointestinal tract.

It is a strong peristaltic bowel movement response, which is classified as irritable bowel syndrome (IBS).
It is recommended to adjust to a regular lifestyle, reduce the intake of greasy foods and dairy products, and manage emotional stress.

More Info


Sudden severe abdominal pain can be alarming and may indicate various gastrointestinal issues. Based on your description, it seems that you experienced a sudden onset of pain while lying in bed, accompanied by significant bowel sounds and a sensation of needing to use the restroom. After a bowel movement, you felt some relief, although you noted that your stool was loose, which could be related to your history of irritable bowel syndrome (IBS).

There are several potential causes for your symptoms. One possibility is that you experienced a bout of abdominal cramping or spasms, which can occur in individuals with IBS. IBS is a functional gastrointestinal disorder characterized by symptoms such as abdominal pain, bloating, and changes in bowel habits, including diarrhea and constipation. Stress, dietary choices, and hormonal changes can exacerbate IBS symptoms, leading to sudden episodes of pain.

Another consideration is the possibility of gastrointestinal obstruction or a blockage, which can cause severe pain and changes in bowel sounds. However, this is less likely if you were able to have a bowel movement afterward. Conditions like diverticulitis, which involves inflammation of pouches that can form in the colon, could also present with sudden pain, but typically, there would be additional symptoms such as fever or changes in appetite.

Additionally, your symptoms could be related to gastrointestinal infections, such as viral gastroenteritis, which can cause sudden abdominal pain, cramping, and diarrhea. If you have recently consumed any questionable food or have been in contact with someone who had similar symptoms, this could be a possibility.

Given that you have a history of IBS, it is essential to consider how your lifestyle and dietary habits may influence your symptoms. Foods that are high in fat, spicy, or contain artificial sweeteners can trigger IBS symptoms. Keeping a food diary may help identify any specific triggers that lead to your abdominal pain.

While your symptoms improved after a bowel movement, it is crucial to monitor for any changes. If you experience persistent pain, fever, vomiting, or blood in your stool, it is essential to seek medical attention promptly. These could be signs of a more serious condition that requires immediate evaluation.

In summary, while your sudden abdominal pain could be related to your existing IBS, it is essential to remain vigilant about your symptoms. If the pain recurs or worsens, or if you develop new symptoms, it would be prudent to consult a healthcare professional for a thorough evaluation. They may recommend diagnostic tests such as blood work, imaging studies, or a colonoscopy to rule out any underlying conditions. In the meantime, managing stress, maintaining a balanced diet, and staying hydrated can help alleviate some IBS symptoms.
