Symptom 6: Cold Intolerance
Cold intolerance, a lesser-known symptom of DKD, is often a perplexing experience for many individuals. This sensation of feeling unusually cold, even in warmer environments, can be linked to several factors associated with kidney disease, including anemia and poor circulation.
Anemia, a common issue in DKD due to decreased production of erythropoietin, can lead to a reduced capacity of the blood to carry oxygen. This decrease in oxygen transport affects the body’s ability to maintain its core temperature, resulting in a heightened sensitivity to cold.
In addition to anemia, DKD can cause changes in circulation. The kidneys play a role in regulating blood pressure and blood flow. When kidney function is impaired, blood flow to the extremities can be reduced, leading to a feeling of coldness, particularly in the hands and feet.
Identifying cold intolerance involves noting a consistent discomfort or chilliness in environments that others find comfortable. It’s more than just a temporary reaction to a cold day; it’s a persistent sensation that can affect comfort and well-being. The sensation of being cold can affect various aspects of daily life, from the need to wear extra layers of clothing to challenges in performing routine tasks in cooler environments. It can also be a subtle sign that anemia or circulatory issues related to DKD need to be addressed.
Managing cold intolerance in DKD involves addressing its root causes, particularly anemia and circulatory issues. This may include iron supplements, erythropoiesis-stimulating agents, and medications to improve blood flow. Maintaining a balanced diet, engaging in regular physical activity to boost circulation, and wearing appropriate clothing to keep warm can also help alleviate the discomfort associated with this symptom.
