What Causes Bladder Infections?

Bladder infections are usually caused by certain types of bacteria multiplying too rapidly or other bacteria that have been accidentally spread from elsewhere.

In normal circumstances, the bladder has a thin mucus layer that forms a barrier between the bladder and urine, which prevents bacteria sticking to the bladder surface. And any invading bacteria are killed by white blood cells. However, if this balance is disrupted then an infection will occur.

You might be surprised to learn that the most common cause of bladder infections is the result of bacteria being spread from the rectal area into the urethra. It is estimated that around 80% of bladder infections are caused this way and triggered by the Escherichia coli (or E.coli) bacteria.

Other bacteria that can result in the need for bladder infection treatment include Saprophyticus which is usually spread by sexual activity particularly in women. If you use barrier methods of birth control then these can destroy the Lactobacill in the vagina thus allowing Saprophyticus and other “bad” bacteria to take hold and because of the relatively short female urethra it is easy for bacteria to spread from the vagina to bladder.

The other common bladder infection cause that you should be aware of is the problem that the bacteria known as candida can have on your urinary tract.

Candida actually performs a very important job in your body, recognizing and destroying other harmful bacteria. In a normally healthy person the number of candida bacteria is tightly regulated – by a properly-functioning immune system and “friendly” bacteria – however should the immune system fail or the number of friendly bacteria decline then candida will multiply.

When this happens the candida actually changes its nature and rather than working with the body its starts to have a negative impact. In its normal yeast state candida is a non-invasive organism but when it becomes fungal it becomes invasive, growing long “roots” that penetrate the intestinal walls. This leads to toxins entering the bloodstream and weakens your immune system further.

As a result of a weakened immune system it is easier for pathogenic bacteria to multiply in your bladder and before long you can end up with a bladder infection or urinary tract infection.

As you can bladder infection causes are predominantly the result of a disturbance in the bacterial balance in the bladder itself which can be a consequence of candida overgrowth, E Coli or the result of certain types of contraception.
