Acido-basic equilibrium and maintenance of homeostasis is essential for life in the body. Body fluids have different pH values, which are regulated with buffers and with exchanging acid and base with kidney, respiratory system (lung) and liver. The effects of individual processes on the regulation of acido-basic equilibrium were studied in the master thesis. The impact of disease states, age and food intake on equilibrium were also studied and in addition, the use of medicines and unregistered preparations for acido-basic equilibrium maintenance and body deacidifying was reviewed. We have found that the diet does not influence the pH of the blood or prevent and treat »acidity of the body«. On the other hand, diet can affect electrolyte balance and the pH of urine. Concentrations of ions are changing with aging and metabolic acidosis is more pronounced. Diseases often disrupt the acido-basic equilibrium in the body. Medications for regulation of acido-basic equilibrium regulate electrolyte concentrations. We also found unregistered preparations meant for regulating acido-basic equilibrium on the market but in reality, they have no effect on the equilibrium.
