Benefiber/Metamucil thickening digestive tract?

I spoke with a nutritionist and he mentioned that taking psyllium products consistently such as Benefiber/Metamucil can cause your digestive tract to thicken. He said the best way to avoid this problem is to take psyllium every other 2 week.
I googled to verify this information but got no results.
Anyone have any idea?

Metamucil

The difference between Benefiber & Metamucil

Fiber acts kind of like a colon cleanser. It moves the food you eat through your digestive tract quicker and the bulk of it is what pushes against the wall of the colon on it’s way out to clean it out. It doesn’t thicken anything but your stool. I don’t understand what your nutritionist means by thickens your digestive tract. The main ingredient there is wheat dextrin.
I think Metamucil is more of a bulking fiber than Benefiber. Too much bulking up of your stool like you get with metamucil isn’t really helpful to a person that suffers from anal fissures because your back side has to stretch too much to pass it, that’s why a lot of us like Benefiber. When you have fissures you need a consistently soft, strain free stool so if you only took it every 2nd week how would that help you in the first week.

I am a HUGE proponent of Benefiber as it really softens things better than any other product I’ve tried. This (on top of Miralax & lots of water) was the only thing that finally helped me heal my fissure after 7 months of debilitating pain & after trying so many different things including botox, LIS, aloe vera, wheatgrass cream, Metamucil, Nifedipine, Nitroglcerin ointment, etc.

I literally felt the tear (glass-passing sensation) every single BM (even 3 months after LIS) until I added Benefiber to my regiment.

How I use Benefiber & Miralax

I take 3 Tablespoons of Benefiber throughout the day & Miralax at night. I make sure to drink 64 oz of water a day. When I get to work, I put 2 Tablespoons of Benefiber into 32 oz of water & sip on it all day. Then, with dinner I have 1 Tablespoon of Benefiber with 16 oz of water. Then, before bed, I take a quarter dose (17 gms is regular dose) of Miralax with 16 more oz of water. I was taking 1-1.5 x a full dose plus the 3 Tablespoons of Benefiber when my fissure was at it’s worst & finally began to heal.
I’ve found it’s easier to use a 32 oz water bottle to make sure I get the 64 oz of water & stick to my schedule.
I can pretty much eat what I want, but I do tend to have a spinach salad & fruit everyday. I usually add peas or chickpeas to my salad for a little more fiber but not always. I think I have a more constipated system than most so don’t know if others would need both Benefiber & Miralax.

At any rate, I wanted to relay my story again & what worked in hopes that it may help someone else. I cannot stress enough about stool consistency! I did not get this & no one stressed to me. I thought things were soft enough for the longest time as it was so much easier to go than what I was used to before the fissure. However, things were not nearly soft enough . . .
need to be the consistency of pudding/soft-serve ice cream in order to heal those suckers! I do recommend shortly after you’ve healed (maybe month) firming things back up though b/c I did experience burning for a while after healing & none of the docs nor I could figure out why since fissure was healed. I am a lifer on the Benefiber & maybe Miralax too
