What could cause someone to fart more than 50 times a day?

Hi doctor,

I regularly perform cardiovascular exercises and weight training. My protein intake daily is about 180 to 210 grams, my fiber intake is anywhere from 20 to 40 grams, and my water intake is approximately 4 liters daily. I fart a lot. I read that the average person should fart 5 to 15 times daily. I fart typically 50+ times a day, and they tend to smell. Is this normal?

I have also attached four files containing textures of my stool. Why do they differ in size and shape?

Hi doctor,

Thank you for the reply.

So there is nothing worrisome like colon cancer or anything I should be worried about?

Hi doctor,

Thank you for the reply.

I am 30 years old. Also, I read on cancer forums that some people only experienced 'being gassy' and that they were diagnosed with colon cancer which makes me worried.

Hi doctor,

Thank you for the reply.

As per my photos, I cannot relate my stools to the bristol stool chart. Why is this?

Hi doctor,

Thank you for the reply.

So there is no reason to push for a colonoscopy?

Hi doctor,

Thank you for the reply.

Are you really a Gastroenterologist? How do I know that I can trust your answer?

Hi doctor,

Thank you for the reply.

I understood; just asking the question. So there is no need to spend my money to go and see a GI specialist?

I only got scared of colon cancer because my friend, who is 33 years old, was diagnosed with colon cancer, and now he has only six months to live.

Hi doctor,

Thank you for the reply.

And I have two final questions:

1. Since the Coronavirus lockdown, I have been getting diarrhea every two to three weeks. Ever since starting Sertraline 50 mg, it was every day but has now disappeared. But I notice my stomach gurgles a little more. Is this normal and related to anxiety?

2. My stools come out with ragged edges. Is this normal? Could it be suggestive of a high fiber diet?

Hi doctor,

Thank you for the reply,

1. I have passed clear mucus in my stool sometimes. Is that a cause for concern?

2. What if the medications do not help?

Hi doctor,

Thank you for the reply.

I have had farting and stool issues for as long as I can remember.

Hi doctor,

Thank you for the reply.

It does not really bother me, to be honest, but maybe I should try a low FODMAP diet. Also, is there any chance that I might have colitis or IBD?

Hi doctor,

Thank you for the reply.

I really appreciate your reply and patience. To summarise, Is stools changing day to day suggestive of what we eat?

Hi doctor,

Thank you for the reply.

One last question,

Ever since taking Sertraline, I notice that near my rectal area is like 'popping or spasming'. What could it be?

Hi doctor,

Thank you for your response.
