Lower abdominal pain can be a complex symptom with various potential causes, and it is essential to approach it with a thorough understanding of the possible underlying conditions. Given your description of persistent pain below the navel, accompanied by a stabbing sensation, changes in bowel habits, and unintentional weight loss, it is crucial to consider several factors before determining the need for further evaluation, such as a colonoscopy.


Potential Causes of Lower Abdominal Pain
1. Gastrointestinal Issues: Conditions such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) like Crohn's disease or ulcerative colitis, and diverticulitis can cause chronic abdominal pain. Your recent history of constipation followed by normal bowel movements could suggest a functional gastrointestinal disorder.

2. Gynecological Factors: In females, lower abdominal pain can also be related to gynecological issues such as ovarian cysts, endometriosis, or pelvic inflammatory disease. If you are female, it may be worth discussing these possibilities with your healthcare provider.

3. Urinary Tract Issues: Conditions like urinary tract infections (UTIs) or kidney stones can also manifest as lower abdominal pain. Symptoms may include changes in urination or pain during urination.

4. Musculoskeletal Pain: Sometimes, pain in the lower abdomen can be referred from musculoskeletal issues, especially if there has been any recent physical activity or strain.

5. Serious Conditions: While less common, serious conditions such as appendicitis, bowel obstruction, or even malignancies should be considered, especially with the presence of weight loss.


When to Seek Further Evaluation
Given your symptoms, particularly the persistent nature of the pain, the stabbing sensation, and the weight loss, it is advisable to seek further evaluation. Here are some guidelines on when to consider additional diagnostic procedures:
- Persistent Symptoms: If the abdominal pain continues for more than a few days without improvement, it is essential to consult a healthcare provider.


- Weight Loss: Unintentional weight loss is a red flag that warrants further investigation. It could indicate an underlying condition that requires treatment.

- Change in Bowel Habits: While you mentioned that your bowel habits have normalized, any significant changes in bowel patterns, especially if accompanied by pain, should be evaluated.

- Severity of Pain: If the pain is severe or worsening, or if it is associated with other symptoms such as fever, vomiting, or changes in urination, immediate medical attention is necessary.


Considerations for Colonoscopy
You mentioned that you recently had a sigmoidoscopy. If the procedure was limited to the sigmoid colon, and your symptoms are persisting, a full colonoscopy may be warranted to evaluate the entire colon for any abnormalities that may not have been visible during the sigmoidoscopy. This is particularly important if there are concerns about inflammatory bowel disease or other significant gastrointestinal conditions.


Conclusion
In summary, your symptoms of persistent lower abdominal pain, especially with the additional concerns of weight loss and changes in bowel habits, suggest that further evaluation is necessary. A discussion with your healthcare provider about the need for a colonoscopy or other imaging studies, such as an abdominal ultrasound or CT scan, would be prudent. It is essential to rule out serious conditions and to ensure that any underlying issues are addressed promptly. Always prioritize open communication with your healthcare provider about your symptoms and concerns to facilitate the best possible care.
