Yes, you can have your family Physician check your child's urine to rule out a possible bladder infection, but 9 times out of 10 a family Physician will not check first for diabetes.  Inexpensive finger stick with results right away.  Signs are bedwetting which parents do not believe is one sign.  If your child has had a thirst problem along with bed wetting, and a fruity smell from his/her breathe take your child to "urgent care" and have a simple finger stick done.  Don't wait to schedule an appointment with your Primary Care Physician, as over time the child will develop Ketones in the urine.  I am an Advocate for my child with Type 1 Diabetes, and it has been 5 years now and what you you wrote brings back memories.  It might not be Diabetes, but have the finger stick along with a Ketone Test (Urine) test. The results are instant.  Do not wait any longer.  If it is not diabetes, then you can have the urine test done for the bladder and other testing to follow.  If you have any further questions, please feel free to contact me.

Health issues such as diabetes and bladder problems can cause bed wetting. My family has learned that stress, anxiety, and nightmares can also cause issues with bed wetting. Sometimes medication can be used to control the bladder to reduce the wetting episodes. If the wetting is due to stress or anxiety, consider having the child seen by a counselor. This can also help in reducing the accidents. Letting your child know that it is ok and that they are not the only child to have these problems can help ease some of their anxiety towards the issue.
