Latent (subclinical) metabolic acidosis (synonyms: Metabolic acidosis, latent; hyperacidity; ICD-10-GM E87.2: acidosis: lactate-) is present when the alkaline buffer reserves in the blood have already been nearly depleted, but there has not yet been a shift in blood pH below 7.36. That is, in latent metabolic (metabolic) acidosis, homeostasis (equilibrium) of pH is still present within its narrow limits between 7.38 and 7.42.
Although disturbances of acid-base balance are common, no figures are available on the prevalence (frequency of disease) and incidence (frequency of new cases) of latent metabolic acidosis. The reason for this is the subclinical occurrence, so that often only the secondary diseases draw attention to the clinical picture.
Course and prognosis: Since latent metabolic acidosis is often not recognized, a “latent connective tissue acidosis” occurs as a result, which can lead, among other things, to demineralization of the skeletal system and thus to osteoporosis. This is particularly true in elderly patients who have a renal (“affecting the kidneys”) latent metabolic acidosis. Thus, latent metabolic acidosis is found in the majority of patients with musculoskeletal complaints and diseases. The treatment of latent metabolic acidosis focuses on therapy of the underlying disease, i.e., the cause, and adequate nutrition. The diet should contain fewer acid-forming foods (e.g. meat, cheese, milk, eggs and sweets) and more base-donating foods (vegetables and fruit). Taking a dietary supplement containing alkaline minerals (magnesium, potassium and calcium citrate) is also recommended.
