Leg ulcersWhy are older people prone to developing leg ulcers?
Leg ulcers are breaks in the skin usually affecting the leg below the calf; the most common site being the inside of the leg just above the ankle bone. They can occur at any age but are more common in older people who have poor circulation. Twice as many women as men suffer from them.
Ulcers are thought to be caused by a combination of sluggish circulation down to the legs and poor blood flow back to the heart through varicose veins.The parts of the body furthest away from the pumping heart are more likely to develop ulcers. In addition, as we get older our skin becomes thinner and more susceptible to injury. Poor circulation also delays the natural healing process.
My elderly mother just seems to be clear of one leg ulcer when another develops. They also take a very long time to heal. Is this normal?
Yes, I'm afraid slow healing of an ulcer is an all too common feature of the condition. Leg ulcers can take several months or even years to heal. Other physical conditions such as diabetes or peripheral vascular disease or reduced mobility can also slow recovery time.
There are, however, some steps your mum can take to promote the healing process. Elevating the legs, if possible rising them above the level of the heart, will help to reduce swelling. The use of pressure bandages or elastic stockings will help sluggish circulation and reduce fluid pooling in the legs.
She should avoid standing for long periods and smoking as both affect the circulation. She should take good care to protect her legs as her skin may be thin and therefore more susceptible to tearing. It's also advisable to avoid hot water bottles as high temperatures can injure the delicate skin.
She usually uses a simple bandage on her ulcers. Is this adequate?
Ulcers require regular, fresh dressings to prevent infection. There are several creams and impregnated bandages that can be obtained from her doctor or chemist that will help reduce the risk of infection and speed healing. Alternatively, she could contact her public health nurse - a professional with a wealth of experience in dealing with this condition - for advice.
