Veggies, Fruits, Cleanliness For Infections

I have been having a lot of infections and I am getting worried. I gues I need to make some changes on my lifestyle. I need to lose weight for health reason and focus on including veggies and fruits on my daily diet.

I have bought some wet wipes to use everytime I go to the washroom. I am trying to avoid washing my hands directly with water because I am having numbness so I always have antibacterial gel and lotion with me to make sure that my hands are always clean specially at work.
