Repetitive constipation over the years. I keep getting told to drink more water, eat more fiber, take miralax?

And now my PCP suggested metamucil daily?

I am a 33m. Around 27-28 I started to have constipation issues. I actually had a hernia that last a couple weeks and receded before a specialist could look at it. I dropped dairy and slowly stopped eating red meat. Red meat just stops everything and makes me feel super sluggish. I have had three PCPs over the years just say "well it isn't good for you anyways, so just stop eating it".. okay so I did.

I really like my current PCP, but her solution was taking miralax daily. Which to me seems odd, like why not try to find out why I have this issue?

This past holiday I was constipated for over a week. It was one of the worst constipation experience I've had. I took miralax, drank prune juice, ate apples, drink tea that is supposed to help you go etc and thought I might have to go to the Dr becuase it was so bad. I was in so much pain and it ruined eating over christmas break. I finally had success after I cam home from visiting my family.

Since then I am good for a couple days, then I slowly get constipated. that lasts 3-4 days and then I can finally go.. But often pebbles for a day or two. It has been so annoying.

I drink plenty of water, I have basically my entire adult life. I eat fairly healthy. We cook most of our food and eat lots of good proteins and fiber. Salmon, Chicken, Turkey, Chickpeas, lentils, beans, broccoli, green beans, fruits, apples, etc. I am eating an apple basically every day.

And I get so incredible bloated when I eat lentils and chickpeas. Those Oli Pop drinks for example completely wreck me. I am so gassy a lot. My wife keeps thinking maybe I didn't get enough fiber, but I can't see how that is true. I've always eaten greens, fruits, beans, etc as an adult. I was actually underweight most of my 20s and now I am struggling to maintain my weight, which is impart probably to to much sugar lately.

Which is one thing I think I should change. Eat less sugary snacks at night.

I even cut caffiene years ago. I do deal with anxiety and I am in therapy for it.

I guess the frustration is that I see the Dr and they question if I am eating enough fiber, drinking enough water, getting enough exercise. I eat better then almost any coworker I've worked with! I eat apples for breakfast, often salads for lunch.. I feel frustrated honestly.

But maybe there is a supplement I could take daily to help? I am a bit hesistant on the miralax or metamucil?

Maybe I need to see a nutritionist or a gut/stomach dr(sorry don't know the correct term)?

At least my dr said that if I made significant diet changes and find a supplement like metamucil and I am still have issues she will consider a colonoscopy.

My curent PCP is great for a lot of things, but I am honestly a bit tired of being told to just not eat red meats, to drink water, and to eat more fiber. When I drink more water then most people I know. How clean does my diet have to be?? It is really tough knowing what I am supposed to do?

Any advice?
