Poop Poop Poop!!!

Damn you are going to lose like 10lbs when you finally let one go

No doubt! What are you going to name it?

Seriously, water, fiber. Also, I am led to believe that more cardio fixes most issues. It's like more cowbell, but with more sweating.

You seriously need to see your doctor. Once in twenty days is not anywhere in the range of acceptable.

While you're waiting to see your doctor I suggest Taco Bell, a Fiber One bar, a hand full of prunes and a Milk of Magnesia chaser. 10 minutes later chug a big glass of water with Epsom salts.

If that doesn't blow out the pipes your doctor will have to pull out the snake.

I kid... but seriously, talk to your doctor and consider running to the pharmacy now for a Fleet enema.

I looked at your diary and you are set at 1200 cals. This is absolutely personal experience, so take it as such:

Low fat is not necessarily your friend
I can't believe I'm about to post this on the forums, but **** it... when I was at 1200 cals, I had some problems. Ate more, no problems.

I too, experienced this. MFP had my daily caloric intake set too low. After doing a lot of research and talking to a lot of sharp people on here, I upped my calories and the problem went away. I began losing weight again too. If you haven't figured out what your TDEE is, definitely do that. BUT, like so many others have said, wait to do ANYTHING until you go see your doc. That is priority one on your list today.

All these suggestions are great, but after 20 days it could be something more serious.
Ever been checked for a hernia? I currently have one and I'm waiting for the surgery to be scheduled, the only reason I knew is it looked like someone shoved a golf ball under my skin.
There is a type of hernia where the intestine get's pinched, causing a backup. I would definitely call a Dr. and ask to be seen immediately.

you need to take the time to try and go every day. If I dont go everyday, I feel awful!

I know a girl who is celiac and when she eats wheat she has this problem. It is darn near impossible to get diagnosed so maybe take a few weeks and stop eating wheat and then try it again and see what happens? Just an idea! Some people get the opposite problems when they are celiac but everyone is different!

You need to go to the doctor. This is not normal and it is past time for you to seek medical attention.

after some really bad food poisoning I was recommended the vitamin "acidophilus". It takes a while (few days) to kick in but its supposed to work as a pro biotic and help reset your system. It helped me reset after I couldn't shake my stomach bug. But I would also absolutely check with a doctor before trying any of this! You don't want to upset an issue you may not know about yet.

someone said bananas.. thats the opposite!! do NOT eat bananas. eat prunes, pears, pear juice, green vegetables. avoid dairy products. go for run. and drink lots o waterrrr. a little miralax wouldnt hurt.
