One of the most frequently mentioned processes is a change in metabolism. When key organs such as the liver or kidneys lose their ability to filter and eliminate toxins effectively, certain substances begin to accumulate in the body. Some of these compounds can be released through breath, skin, or bodily fluids, creating unusual odors. People often describe them as sweet, metallic, or simply different from typical human body smells.
Circulation and Skin Changes
Changes in blood circulation also play an important role, especially in patients with severe illness or extreme weakness. When blood flow to the skin and extremities is reduced, variations occur in temperature, moisture, and skin chemistry. These conditions can contribute to stronger odors, particularly if the person remains at rest for long periods or has very limited mobility.
