Gastrointestinal issues


Hello doctor, I am 16 years old.
This year, I have been experiencing constipation issues and have been going to a large hospital, where I have a bowel movement approximately every 3 to 4 days.
The doctors have only prescribed me Laxative Granules, which have a stool-softening effect.
There are about 20 packets in a box.
Initially, I only took one or two packets, and I felt that it made bowel movements much easier.
However, later on, due to psychological factors, I felt that I shouldn't rely on medication for bowel movements, so I only ate bananas for a year, but it didn't seem to help much.

I have also been experiencing intermittent pain in my lower left abdomen for about six months, and it feels slightly swollen in that area, though it is not protruding and is more swollen than the right side.
My stools have initially become thin and hard, but there has been no blood.
I am not sure if it is just an illusion, but I keep noticing a slight redness around my anus, although there is no blood when I wipe.

In the past two months, I have been busy with school celebrations, going to bed around 1 or 2 AM and waking up at 6:30 AM.
My bowel movements have become hard and pellet-like, but I drink plenty of water! Still, there is no blood.
Should I consider getting a colonoscopy?

Hello, based on your description, the main issue seems to be constipation.
There are several risk factors associated with constipation, including lack of exercise, insufficient intake of vegetables, irregular sleep patterns, and frequent late nights.
It is likely that these risk factors are contributing to your constipation.
I recommend increasing your physical activity, consuming more vegetables, and avoiding late nights, as these changes can help improve your condition.

Typically, constipation leads to harder stools, which can irritate the intestinal walls and cause minor bleeding, which is likely what you have observed.
Usually, these symptoms will resolve once constipation improves.
If you are still concerned, you may want to test your stool for occult blood.
If occult blood is present, then a colonoscopy may be necessary.
Thank you for your question.

Based on your description of gastrointestinal issues, it seems you have been experiencing significant constipation, abdominal pain, and changes in your bowel habits over the past year. Given your age and the symptoms you've outlined, it is essential to approach this situation with care and consideration.

Firstly, let's address your constipation. You mentioned that you were prescribed a laxative (Lactulose) which initially helped but later you became hesitant to rely on medication for bowel movements. It's common for individuals to feel apprehensive about long-term use of laxatives, but it's important to understand that chronic constipation can often require ongoing management. Dietary changes, such as increasing fiber intake through fruits, vegetables, and whole grains, along with adequate hydration, can significantly help in managing constipation. However, if dietary changes alone are insufficient, it may be necessary to continue using laxatives under medical supervision.

The left lower abdominal pain you described, along with the sensation of slight swelling, is concerning and warrants further evaluation. While it could be related to constipation or functional gastrointestinal disorders like Irritable Bowel Syndrome (IBS), it is essential to rule out any other potential causes. The fact that your stool has become harder and more pellet-like suggests that your bowel is not moving as efficiently as it should, which can lead to discomfort and pain.

Regarding the question of whether you should undergo a colonoscopy, it is generally not the first-line investigation for someone your age unless there are alarming symptoms present. These symptoms include significant weight loss, blood in the stool, severe abdominal pain, or a family history of colorectal cancer. However, given your ongoing symptoms and the fact that you have been experiencing abdominal pain for several months, it would be prudent to discuss this with your healthcare provider. They may recommend a colonoscopy or other diagnostic tests, such as imaging studies or laboratory tests, to better understand the underlying cause of your symptoms.

In addition to a colonoscopy, your doctor may suggest other evaluations, such as an abdominal ultrasound or CT scan, to assess for any structural abnormalities. It's also important to consider a referral to a gastroenterologist, who specializes in digestive disorders and can provide more targeted management for your symptoms.

Lastly, it’s crucial to address your lifestyle factors, including sleep patterns and stress levels, as these can significantly impact gastrointestinal health. Poor sleep and high stress can exacerbate gastrointestinal symptoms, including constipation and abdominal pain. Establishing a regular sleep schedule and incorporating stress-reducing activities, such as exercise or mindfulness practices, may help improve your overall well-being.

In summary, while a colonoscopy may not be immediately necessary, it is essential to have a thorough discussion with your healthcare provider about your symptoms. They can help determine the best course of action, which may include dietary modifications, medication adjustments, and possibly further diagnostic testing to ensure your gastrointestinal health is appropriately managed. Remember, early intervention can often lead to better outcomes, so do not hesitate to seek further medical advice.
