Narrow Stools: Causes, Concerns, and Testing Costs

Stool becomes thin?

Hello, I would like to ask about the issue of having thinner stools.
I am 20 years old and after reading some articles, I feel a bit anxious.
I noticed that my stools have become thinner, and sometimes when I stand up too quickly after sitting, I experience symptoms of anemia.
I used to neither smoke nor drink, and I don't have any other significant abnormalities.
What is considered normal regarding the thickness of stools and the frequency of bowel movements? If I am concerned, how much would a fecal occult blood test typically cost? Thank you.

Young people who experience dizziness when standing up too quickly are often experiencing orthostatic hypotension rather than anemia.
It is generally believed that stool must be thinner than a pinky finger to be considered truly narrowed, but not all cases of colorectal cancer will present with stool narrowing.
The frequency of bowel movements varies from person to person; as long as it does not cause discomfort or interfere with daily life, having bowel movements anywhere from three times a day to once every three days is not considered abnormal.
For fecal occult blood testing, both types are covered by health insurance: 1.
A chemical method that can detect gastrointestinal bleeding, and 2.
A more accurate immunological method.

More Info

Narrow stools, or thin stools, can be a source of concern for many individuals, especially when they notice a change in their bowel habits. At the age of 20, it is understandable to feel anxious about such changes, particularly if they are accompanied by other symptoms like dizziness or feelings of anemia. Let's delve into the potential causes, concerns, and the costs associated with testing for narrow stools.

Causes of Narrow Stools
Narrow stools can be caused by several factors, and while they are often benign, they can sometimes indicate underlying health issues. Here are some common causes:
1. Dietary Factors: A diet low in fiber can lead to changes in stool consistency and shape. Foods that are low in fiber, such as processed foods, can contribute to narrower stools.

2. Dehydration: Insufficient fluid intake can lead to harder, narrower stools as the body absorbs more water from the waste material in the intestines.

3. Bowel Obstruction: A more serious cause of narrow stools can be a partial obstruction in the intestines. This could be due to conditions such as tumors, strictures, or inflammatory bowel diseases (IBD) like Crohn's disease or ulcerative colitis.

4. Anal or Rectal Issues: Conditions affecting the anal or rectal area, such as hemorrhoids or anal fissures, can also lead to changes in stool shape.

5. Colon Cancer: Although less common in younger individuals, persistent changes in stool shape, especially if accompanied by other symptoms like blood in the stool, weight loss, or changes in bowel habits, should be evaluated by a healthcare professional.

Concerns
While occasional changes in stool shape can be normal, persistent narrow stools warrant further investigation, especially if accompanied by other symptoms such as:
- Blood in the stool
- Significant weight loss
- Changes in bowel habits (e.g., diarrhea or constipation)
- Abdominal pain or discomfort
- Anemia symptoms, such as fatigue or dizziness

Testing and Costs
If you are concerned about your narrow stools, it is advisable to consult with a healthcare provider. They may recommend a stool test to check for blood (fecal occult blood test) or other abnormalities. The cost of such tests can vary widely based on location, healthcare provider, and whether you have insurance. In the United States, a fecal occult blood test typically ranges from $20 to $100. If further testing is required, such as imaging studies (like a colonoscopy), the costs can increase significantly, often ranging from several hundred to thousands of dollars, depending on the complexity of the procedure and the facility.

Conclusion
In summary, while narrow stools can be a benign issue related to diet or hydration, they can also indicate more serious health concerns. Given your age and the symptoms you've described, it is essential to monitor your condition closely and seek medical advice if the changes persist or worsen. A healthcare provider can offer personalized guidance, recommend appropriate tests, and help alleviate your concerns. Remember, early detection and intervention are key in managing any potential health issues effectively.
