My mother needs help finding a cure for urinary incontinence during the night. she goes 4 or 5 times .?

She needs to consult her GP who will refer her to see a Urologist first who will want to examine her and perform a few tests.

It may be that surgery would help your Mum and that will be discussed if it is an option. Exercises are also an option and it may well be that the Urologist will refer your Mum to a specialist continence nurse who can advise her how to cope with it and what aids are available.

GP is the best course of action to begin with though.

Antibiotics for urinary tract infections are the most effective treatment. More than 85% of cases can be cured with one simple dose of an oral antibiotic. More complicated cases involving kidney infection may involve antibiotic injection, or longer courses of oral antibiotics.
Cranberries are thought to be an excellent natural cure for urinary tract infections. They work by killing bacteria in your urinary tract. Cranberries contain high doses of Vitamin C, which increase the acidity of your urine. This may increase pain during urination though. Blueberries contain proanthocyanidins, which prevent E.coli from attaching to the walls of your urinary tract. This will prevent future urinary tract infections. Castor oil is a good home remedy for urinary tract infection. It is thought to soothe inflammation in the abdomen. Apply oil directly to the skin, and cover with a warm washcloth or hot water bottle for 30 to 60 minutes.
