So I go to the toilet to take a dump and when I'm done I don't wipe it wash myself but then when I wash myself there is a feeling of something still left but I can never take it out. I also have a lot of gas.
This may reflect that your gut bacteria is not healthy anymore or your not exercising, or both.
Use probiotic drink.
Try taking more fibre such as oranges, grapes and prune juice and try a stool softener. Make sure you eat plenty of vegetables too. Exercise is also good for moving your bowel.
