increase acidity in the blood and other body tissue, an increased hydrogen ion concentration.
Metabolic acidosis: In medicinal chemistry, metabolic acidosis is a condition that occurs when the body produces too much acid or when the kidneys are not removing acid from the body So, Metabolic acidosis is generation of hydrogen ions or acid formation by biochemical process is a sub part of chemical process Regards (Syed Burhanuddin Abdali) Principal Scientific Officer PCSIR Laboratories complex, Karachi Ministry of Science &Technology Government of Pakistan

In medicine, metabolic acidosis is a condition that occurs when the body produces too much acid or when the kidneys are not removing enough acid from the body.
If unchecked, metabolic acidosis leads to acidemia, i.e., blood pH is low (less than7.35) due to increased production of hydrogen by the body or the inability of the body to form bicarbonate (HCO3-) in the kidney.
Its causes are diverse, and its consequences can be serious, including coma and death.
Together with respiratory acidosis, it is one of the two general causes of acidemia.
