Blue nails can signal underlying health issues that require attention
Blue nail plates often reflect problems within the body that deserve careful evaluation. A cardiovascular surgeon notes that these changes can point to a range of conditions affecting veins, the lungs, and the circulation. In Volokolamka, the head of the vascular surgery department at the hospital of the Russian Railways Medical Center emphasizes that blue nails should never be ignored. They may indicate systemic issues that need timely assessment to prevent complications and preserve limb health.
There are several plausible explanations for blue nails. They can arise from chronic diseases of the veins and respiratory system, circulatory problems, and peripheral vascular disease. Severe venous insufficiency and atherosclerosis of the arteries can reduce blood flow and lead to ischemia in the extremities. For instance, chronic obstructive pulmonary disease, which is prevalent among smokers, can cause nails to take on a blue tint. In limb ischemia, a patient may experience pain in the arm or leg even if overall health seems stable. Symmetric nail color changes across both hands or both feet may point to systemic inflammatory or vascular diseases that have progressed without prompt treatment, according to the specialist.
When blue nails appear, delaying a medical visit is not advised. Early diagnosis is crucial to identify the root cause and to prevent serious outcomes. A clinician will typically assess breathing, circulation, and the skin and nails themselves to determine the best course of action and to rule out conditions that require urgent care.
The medical professional stresses that blue nails can have several common origins, and a thorough examination is essential to distinguish between them. By understanding the potential causes, patients can seek appropriate testing and management that address both symptoms and the underlying disease.
