Strange sensations in the lower abdomen?


Hello: Two weeks ago, I started feeling some unusual sensations in my lower abdomen; it wasn't pain, but rather a feeling as if something was stirring.
This week, I began to experience pain that feels similar to menstrual cramps.
Initially, I was concerned it might be related to my menstrual cycle, so I consulted a gynecologist and had an ultrasound.
The doctor indicated that there were no signs of an impending period.
This morning, when I transitioned from lying down to standing up, I felt pain.
Throughout the day, I noticed that moving from sitting to standing also causes a brief pain.
Given that there is a family history of colorectal cancer and I usually experience irregular bowel movements and poor digestion, I have been particularly attentive.
However, for the past two months, my bowel movements have been normal, occurring daily without issues.
My weight has not increased, but my abdominal circumference has slightly enlarged.
I do not typically take medication, but I have been consuming chitosan and red yeast rice as dietary supplements.
Thank you.

Hello: The main organs in the lower abdomen of women include the intestines and gynecological organs.
Since your gynecological organs have been examined and found to be normal, the discomfort you are experiencing is likely originating from the intestines.
To determine if there is an issue with the intestines, a colonoscopy or a barium enema is necessary.
Given that you are in a high-risk group for colorectal cancer, it is recommended that you undergo a colonoscopy.
Additionally, it is advisable to consume more high-fiber foods such as vegetables and fruits to improve digestive issues.
Sincerely, Dr.
Yang Pei-Chen, Director of the Gastroenterology Department, Taoyuan Hospital, Ministry of Health and Welfare.

More Info


Unusual sensations in the lower abdomen, especially when accompanied by pain, can be concerning and warrant further investigation. Based on the symptoms you've described, it seems that you are experiencing a range of sensations that could be attributed to gastrointestinal issues. The initial feeling of something "stirring" in your abdomen, followed by pain that resembles menstrual cramps, suggests that there may be some underlying gastrointestinal disturbance.

Given your family history of colorectal cancer and previous irregular bowel habits, it is prudent to approach this situation with caution. The fact that you have recently experienced a change in sensation, along with pain that occurs when transitioning from sitting to standing, could indicate several potential issues. These might include gastrointestinal motility disorders, such as irritable bowel syndrome (IBS), or even structural issues like diverticulitis or other forms of colonic inflammation.

The absence of menstrual symptoms, as confirmed by your gynecologist, helps to rule out gynecological causes for your discomfort. However, the pain you experience when changing positions could also suggest that there is some form of mechanical irritation or pressure in the abdominal cavity, possibly related to the intestines or other abdominal organs.

Your mention of having normal bowel movements over the past two months is encouraging, as it suggests that there may not be an active gastrointestinal obstruction. However, the increase in abdominal girth could indicate bloating or distension, which is often associated with gastrointestinal issues such as gas accumulation or changes in bowel habits.

It is essential to consider dietary factors as well. You mentioned taking chitosan and red yeast rice supplements, which can have varying effects on digestion and metabolism. While these supplements are often used for weight management and cholesterol control, they may also influence gastrointestinal motility and could contribute to your symptoms.

In light of your family history of colorectal cancer, it is highly recommended that you undergo a colonoscopy. This procedure is crucial for visualizing the interior of the colon and can help identify any polyps, lesions, or other abnormalities that may not be apparent through imaging studies like ultrasound or X-rays. Additionally, a colonoscopy can help rule out conditions such as inflammatory bowel disease (IBD) or diverticular disease, which could explain your symptoms.

In the meantime, you may benefit from dietary adjustments. Increasing your intake of fiber-rich foods, such as fruits, vegetables, and whole grains, can help promote regular bowel movements and improve overall digestive health. Staying hydrated is also vital, as adequate fluid intake can help prevent constipation and support healthy digestion.

Lastly, managing stress and anxiety is crucial, as these factors can significantly impact gastrointestinal function. Techniques such as mindfulness, yoga, or even simple breathing exercises can help alleviate some of the discomfort you are experiencing.

In summary, while your symptoms may not indicate an immediate emergency, they do warrant further investigation, especially given your family history. A thorough evaluation by a gastroenterologist, including a colonoscopy, is recommended to rule out any serious conditions and to provide you with peace of mind. In the meantime, focus on dietary improvements and stress management to help alleviate your symptoms.
