What is a symptom of metabolic acidosis due to increased hydrogen ions in the blood?

The presence of increased hydrogen ions in the blood is a key factor in the development of metabolic acidosis. This condition occurs when there is either an excess production of hydrogen ions or a decreased ability of the kidneys to eliminate these ions, leading to a drop in blood pH. As the concentration of hydrogen ions rises, the acidity of the blood increases, resulting in a condition known as acidosis. Therefore, increased acidity in the blood is a direct symptom of metabolic acidosis, demonstrating a fundamental aspect of this metabolic disturbance.

In this context, the increased acidity of the blood not only serves as a symptom but also characterizes the underlying metabolic condition. Other symptoms or physiological responses are influenced by the severity of acidosis but do not define the condition itself as fundamentally as increased acidity does.
