Abdominal distension and narrowed stools?

Hello doctor, I have been experiencing bloating in my intestines and stomach for the past few days, along with frequent burping and flatulence.
My appetite has not decreased, and there is no blood in my stool, but it is thin, unformed, and has a fluffy texture with a golden color.
Sometimes, it contains undigested food.
I also have abdominal bloating, which can be painful at times.
My mother (first-degree relative) passed away from colon cancer.
Could this be a symptom of colon cancer? This condition has suddenly appeared in the last few days; everything was normal before.
I am 17 years old and male.
Thank you, doctor.

More Info

Bloating and changes in stool consistency can be concerning symptoms, especially given your family history of colon cancer. However, it is essential to understand that these symptoms are not definitive indicators of colon cancer. Let’s break down your symptoms and their potential implications.

Understanding Your Symptoms
1. Bloating and Gas: Bloating can result from various factors, including dietary choices, food intolerances, or gastrointestinal issues. Common culprits include high-fiber foods, carbonated beverages, and certain carbohydrates that are poorly absorbed. If you’ve recently changed your diet or consumed more fiber than usual, this could explain the bloating and gas.

2. Thin or "Stringy" Stool: The appearance of your stool can be influenced by several factors. Thin stools can sometimes be a sign of a narrowing of the intestinal passage, which could be due to various reasons, including inflammation, infection, or, in rare cases, a mass. However, thin stools alone are not a definitive sign of colon cancer, especially in the absence of other symptoms like blood in the stool or significant changes in bowel habits.

3. Abdominal Pain: Occasional abdominal pain can be linked to many benign conditions, such as gas, constipation, or even stress. However, if the pain is persistent or severe, it warrants further investigation.

4. Family History: Having a first-degree relative (like your mother) who had colon cancer does increase your risk of developing the disease. The general recommendation is that individuals with a family history of colorectal cancer should begin screening earlier than the standard age of 45, often around 10 years before the age at which the family member was diagnosed.

When to Seek Medical Attention
Given your symptoms and family history, it is advisable to consult a healthcare professional. They may recommend a thorough evaluation, which could include:
- A Detailed Medical History: Discussing your symptoms, family history, and any other relevant factors.

- Physical Examination: A healthcare provider may perform a physical exam to check for any abdominal tenderness or masses.

- Diagnostic Tests: Depending on the findings, tests such as blood work, imaging studies (like an abdominal ultrasound or CT scan), or even a colonoscopy may be warranted to rule out any serious conditions.

Conclusion
While your symptoms of bloating, gas, and thin stools can be concerning, they are not definitive signs of colon cancer, especially in a 17-year-old. However, given your family history, it is crucial to take these symptoms seriously and seek medical advice. Early detection and intervention are key in managing any potential issues, particularly with a family history of colorectal cancer. Remember, only a healthcare professional can provide a proper diagnosis and recommend the appropriate next steps based on your individual situation.
