Constipation: Causes, Symptoms, and When to Seek Help - Gastroenterology and Hepatology

More Info

Constipation is a common gastrointestinal issue characterized by infrequent bowel movements, difficulty passing stools, or the sensation of incomplete evacuation. It can significantly affect a person's quality of life and may be caused by a variety of factors, including dietary habits, lifestyle choices, and underlying medical conditions.


Causes of Constipation
1. Dietary Factors: A diet low in fiber can lead to constipation. Fiber helps to bulk up the stool and facilitates its passage through the intestines. Insufficient fluid intake can also contribute to hard, dry stools.

2. Sedentary Lifestyle: Lack of physical activity can slow down the digestive system. Regular exercise promotes healthy bowel function.

3. Medications: Certain medications, including opioids, antacids containing aluminum, and some antidepressants, can cause constipation as a side effect.

4. Medical Conditions: Conditions such as hypothyroidism, diabetes, irritable bowel syndrome (IBS), and neurological disorders can affect bowel function.

5. Psychological Factors: Stress, anxiety, and depression can also impact bowel habits.


Symptoms of Constipation
Common symptoms include:
- Infrequent bowel movements (typically fewer than three times a week)
- Hard or lumpy stools
- Straining during bowel movements
- A feeling of blockage or obstruction in the rectum
- Abdominal discomfort or bloating

Blood in Stool
The presence of bright red blood in the stool can be concerning. While it may not always indicate a serious condition, it is essential to consider the following:
1. Hemorrhoids: These are swollen veins in the rectum or anus that can bleed during bowel movements, especially if straining occurs. This is a common cause of bright red blood.

2. Anal Fissures: Small tears in the lining of the anus can occur due to passing hard stools, leading to bleeding and pain.

3. Diverticular Disease: Diverticulosis can lead to diverticulitis, which may cause bleeding.

4. Polyps or Colorectal Cancer: While less common, these can also present with blood in the stool and should be evaluated, especially if there are changes in bowel habits or other concerning symptoms.


When to Seek Help
Given your symptoms of constipation over the past four months, along with the recent discovery of bright red blood during bowel movements, it is crucial to seek medical attention. You should consult a healthcare provider if you experience any of the following:
- Blood in the stool, especially if it is bright red or accompanied by other symptoms.

- Significant changes in bowel habits that persist for more than a few weeks.

- Severe abdominal pain or discomfort.

- Unexplained weight loss.

- A family history of gastrointestinal diseases.


Conclusion
Constipation can often be managed with lifestyle changes, such as increasing dietary fiber, staying hydrated, and engaging in regular physical activity. However, the presence of blood in your stool warrants further investigation to rule out any serious underlying conditions. It is advisable to schedule an appointment with a healthcare professional who can perform a thorough evaluation, possibly including a physical examination and diagnostic tests, to determine the cause of your symptoms and recommend appropriate treatment.
