Factors that break wudhu

Q:

1. If a woman has a leucorrhea discharge problem and she knows after an hour or so she will experience a discharge but after performing ablution she inserts a tissue in the private area and offers her prayers the whole day knowing the fact that the discharge will be there when she will remove the tissue, will the salah perform in such condition be valid?

2. What is the shariah ruling regarding this?

3. Should she remove the tissue, clean and wipe the private area and then perform a fresh ablution when she knows she discharged?

4. If she does not insert the tissue and she offers her prayer and in the prayer she feels the discharge, will the wudhu break? Does she need to perform salaah again?

Q: During Salah I sometimes feel as if there are some air bubbles that pass out through my front passage. However there is no smell or sound. This causes me great uncertainty. Does this wind from a woman's front passage break wudu? I am Hanafi.

Q: I have a minor leakage from my anus. I don’t feel when it’s leaking and I don’t see any stains on my undergarment, but for the last few days while I’m walking or in a standing position, I feel stickyness between my legs and I feel there’s something leaking which doesn’t appear. Will this break my wudhu, do I need to take ghusl?

Q: I am a woman and suffer regular vaginal discharge. Sometimes after sexual arousal, I am certain that the discharge which is present is normal vaginal discharge because during arousal or sexual thoughts I didn't have any discharge nor there was climax nor any fulfillment nor any orgasm. Is wudhu sufficient to offer salaah?

Q: My toe was hit by a heavy thing falling down and it caused some blood to emerge within the nail. I heard that blood on the surface was pure and I washed the toe and did not think about it. Weeks later I thought about this again when I saw the dried up blood in my nail (Note: some of the blood was within my nail so I cannot remove it, otherwise I would need to remove my nail!) and I don’t know if that counts as pure or impure. 

Q: I wasn’t sure if I had passed gas during salah, so as the hadith mentioned (not to stop prayer until a sound is heard or smell is detected) I stopped recitation for a moment and tried to detect a smell. I didnt smell anything and I resumed. Was this ok of me to do?

Q: Through eating camel meat, will the wudu break according to the Hanafi mazhab? 

Q: If whilst brushing the teeth, some blood is seen in the saliva, does this break the wudhu?

Q:

1. I have cavities in my tooth, and when I eat, food gets stuck. When I rinse my mouth or use miswak, it's still stuck. But when I brush my teeth, it easily comes out. Should I brush my teeth before I perform wudhu everytime I eat, or is it okay for the food to be stuck in the cavities?

2. Is it permissible to have dental fillings so that food doesn't get stuck, or is the filling regarded the same as stuck food? If it is permissible, is there any specific type which should be used as a filling? For example, the fillings come in gold, porcelain, a composite resin (tooth-colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).

3. Sometimes, the food eaten comes back to mouth unintentionally. When this happens, does wudhu break? What about fast?

Q: I read that wudhu breaks when fluid comes out of the eye due to eye pain. Is this correct?

Will allerges and itchy/dry eyes fall under this?
