Hello doctor, My mother is having black circular patches on her legs. What could be the reason? Someone said it could be due to improper circulation of blood in the lower part of the body. It usually happens when the blood becomes thick. Can you please help me to understand the reason behind this? My mother is suffering from a cervical problem also. Please share your valuable advice and opinion.
Hello. The most common cause is old age. In old age, small vessels become fragile and rupture, leading to blackish bruises, common in lower limbs but can occur anywhere in skin. Another cause is medicines. If a person is using drugs called steroids or anticoagulants or antiplatelets, then such bruises can occur. Another cause is trauma. In old age, an only minor injury can cause bruises as vessels are fragile. No relation to what you called thick blood or so. Rare causes are some disorders of the coagulation system, platelet function, etc. Is she suffering from any chronic disease or is she using some medicines? Please give a complete history and also send pictures of bruises so that I may guide you properly.
