Should You Get a Colonoscopy? Symptoms and Concerns

Do you need to have a colonoscopy?

For about the past month, I have been experiencing increased constipation, and sometimes there is fresh blood in my stool.
However, the blood in my stool is not only present after constipation; I have experienced this before, but it has become more frequent recently.
About a month ago, I started having a dull pain in my lower left abdomen, and sometimes I feel a bit of numbness in my left leg.
I'm not sure if this is psychological because I don't notice it unless I pay attention.
Recently, I have also been having frequent abdominal pain, but I can't seem to have a bowel movement.
Upon percussion, my abdomen feels full of gas, and I suspect my stool has become narrower, although it's not very obvious.
There is no family history of colorectal cancer.
I usually drink water and eat fruits and vegetables, but I also consume fried foods and hot dogs.
Could this be colorectal cancer? 😭

The likelihood of hemorrhoidal bleeding is highest.
It is advisable to first consult a colorectal surgeon.

More Info

When considering whether to undergo a colonoscopy, it's essential to evaluate your symptoms and any potential risk factors. Based on your description, you are experiencing several concerning symptoms: increased constipation, blood in your stool, left lower abdominal pain, and changes in your bowel habits. These symptoms warrant further investigation, particularly given the presence of blood in your stool, which can be indicative of various gastrointestinal issues, including but not limited to hemorrhoids, diverticulitis, or more serious conditions such as colorectal cancer.

Colorectal cancer is a significant health concern, especially for individuals over the age of 45 or those with a family history of the disease. However, even in the absence of a family history, the symptoms you describe should not be ignored. Blood in the stool, particularly if it is bright red, can suggest bleeding from the lower gastrointestinal tract, which may be due to conditions such as hemorrhoids or polyps, but it can also be a sign of more serious issues like cancer.

The left lower abdominal pain you are experiencing could be related to several factors, including constipation, which can cause discomfort and a sensation of fullness due to trapped gas. The fact that you mention your stool has become thinner could also be a concern, as changes in stool caliber can sometimes indicate an obstruction or mass in the colon.

Given these symptoms, a colonoscopy is a valuable diagnostic tool that allows for direct visualization of the colon and rectum. It can help identify any abnormalities such as polyps, inflammation, or tumors. Additionally, if any suspicious lesions are found during the procedure, they can often be biopsied or removed at that time, which can be crucial for early detection and treatment of potential malignancies.

While concerns about discomfort and risks associated with colonoscopy are valid, advancements in medical technology have made the procedure much more tolerable. Many patients are now offered sedation options, including conscious sedation or even general anesthesia, to minimize discomfort during the procedure. The risks associated with colonoscopy, such as perforation or bleeding, are relatively low, especially when performed by experienced professionals.

In summary, given your symptoms of constipation, blood in the stool, abdominal pain, and changes in bowel habits, it is advisable to consult with a gastroenterologist about undergoing a colonoscopy. Early detection is key in managing potential gastrointestinal issues, and a colonoscopy can provide critical information that can guide your treatment and management plan. It’s essential to address these symptoms promptly to ensure your health and peace of mind.
