Inconsistent defecation in a 23 years old male

Hello
I'm a 23 years old male, I have incosistent defecation. In most days, I wake up with a need to have a defecation. Sometimes the fence starts normal (type 3 or 4 in the Bristol scale) and then it turns to be a diarrhea fence (types 5,6 and even 7) in the same defecation.
In most days, I have 2-4 defecations immediately after I wake up, and then no defecation in the entire day OR I have  a normal defecation or a constipation defecation (type 2 or 1) after I have ate.
I have to mention that in cold mornings and in exam periods (I'm an engineering student), the phenomenas mentioned above occurs more frequently.

Does a Colorectal cancer may be the reason ? As I mentioned I'm a 23 years old male with no family members having a colorectal cancer.

Kind regards

It is not colorectal cancer.  You most likely have IBS which has symptoms of differing consistencies of bowel movements and that it is worse when stressed.  You should be checked out by a GI doctor to make sure this is what's going on.  In the mean time you should try taking probiotics, either in pills or yogurt.

Hi rashed123- just wondering if you ever were diagnosed for your problem? I have a very similar problem and have had it for years. I'm planning to go see a doctor about it but was wondering if you have had any resolution?

Please let me know when you have a second.

Thanks
