Lower Abdominal Pain and Bowel Issues in Teens

Lower abdominal pain and bowel issues?

Hello, Doctor.
I have a few questions.
I recently finished my menstrual period, and I sometimes feel pain in my lower abdomen, on both the left and right sides.
Last night, when I went to the bathroom, my stool was a bit hard, and I noticed some reddish spots on it.
I'm not sure if it's blood or something else.
There was also a small, dense, red, fibrous-looking substance.
A couple of days ago, I ate bananas and guavas; could that be the fiber from those? The tissue paper also had some fibers on it, but this morning, I didn't see any blood when I went to the bathroom.
Recently, my stools have been yellow, and I've been undergoing treatment for a peptic ulcer with pantoprazole, which has made it difficult to digest vegetables and fruits completely, resulting in softer stools.
In middle school, I used to eat a lot of fried foods, but now that I'm in high school, I know fried foods are not good, so I eat more vegetables and less meat, and I also include fruits.
I'm worried that my previous diet might have caused some issues.
I'm only 16; could I be at risk for any serious illnesses? By the way, the doctor also prescribed me probiotics.

P.S.
1.
Two months ago, I reported soft stools to my gastroenterologist, who ordered a stool occult blood test, which came back negative.
The doctor said there was no need for further testing since my age makes the risk of colon cancer almost zero, so I shouldn't worry too much.
If the stool test is fine, there's no need for invasive examinations.
2.
A few weeks ago, I had mucus in my stool, and after I showed a picture to the doctor, he said it was due to colitis, and after taking medication, the mucus disappeared.
3.
I am currently still being treated for a peptic ulcer and taking pantoprazole.
Thank you, Doctor, for taking the time to respond.

Lower abdominal pain right after your menstrual period is often related to the menstrual cycle.
If you notice something that looks like fiber in your stool, it is indeed fiber; the human digestive system does not absorb fiber.
As for occasional red streaks without accompanying symptoms, many people experience this due to food residue coloration, so there is no need to worry too much.
At your age, it's understandable to be concerned, but just follow up with your gastroenterologist and discuss any symptoms during your appointments.

More Info

Lower abdominal pain and bowel issues in teenagers can be concerning, especially when accompanied by changes in bowel habits, the presence of blood or mucus in stools, and other gastrointestinal symptoms. Based on your description, it seems you are experiencing a combination of abdominal pain, hard stools, and occasional blood or red discoloration in your stools, which can understandably cause anxiety.

Firstly, it's important to recognize that lower abdominal pain can arise from various causes, including gastrointestinal issues, menstrual cramps, or even urinary tract problems. Given that you recently finished your menstrual period, it is possible that some of the pain you are experiencing could be related to menstrual discomfort, which is common among adolescents. However, if the pain is persistent or severe, it warrants further investigation.

Regarding your bowel issues, the presence of hard stools and occasional blood can indicate constipation or anal fissures. Constipation is often characterized by infrequent bowel movements, hard stools, and straining during defecation. The blood you observed could be due to small tears in the anal lining (fissures) caused by passing hard stools. The fibrous material you mentioned might indeed be remnants of the fruits you consumed, such as bananas and guavas, which are high in fiber. However, if you notice blood consistently or if it worsens, it is crucial to seek medical attention.

You mentioned that you are currently undergoing treatment for a gastric ulcer and taking medications like pantoprazole (耐適恩). This medication can affect your digestive system and may lead to changes in bowel habits. It is essential to maintain a balanced diet rich in fiber, which can help alleviate constipation. Foods such as fruits, vegetables, whole grains, and adequate hydration are vital for promoting healthy bowel movements. Since you have shifted to a healthier diet, it is a positive step towards improving your gastrointestinal health.

Your concern about developing serious conditions like colorectal cancer at a young age is understandable, but it is important to note that the risk is extremely low in teenagers. Your healthcare provider's reassurance regarding the negative results from the fecal occult blood test is a good indicator that there are no immediate concerns. However, if you continue to experience symptoms such as persistent abdominal pain, changes in bowel habits, or the presence of blood, it is advisable to follow up with your healthcare provider for further evaluation.

In summary, while your symptoms may be related to dietary habits, menstrual cycles, or the effects of medication, it is crucial to monitor your condition closely. If symptoms persist or worsen, do not hesitate to consult with a gastroenterologist or your primary care physician for a thorough assessment. They may recommend dietary adjustments, lifestyle changes, or further diagnostic tests to ensure your gastrointestinal health is on the right track. Remember, maintaining open communication with your healthcare provider is key to addressing any health concerns you may have.
