The treatment of low bicarbonate varies according to the cause. If the cause is dietary, it is usually enough to pay attention to dietary regulation; if there are related diseases (acute diarrhea, respiratory failure, acute renal failure, etc.), the treatment includes medication (oral sodium bicarbonate, intravenous sodium bicarbonate), respiratory therapy and dialysis therapy. 1. Dietary causes: bicarbonate values will not be significantly low. If too much acidic food is consumed, the diet can be modified to avoid meat. 2. Disease-related: bicarbonate value may be significantly low. Consider the existence of acid-base balance disorder, can be seen in acute diarrhea, respiratory failure, acute renal failure and other diseases. If acute diarrhea can be improved by oral or drip sodium bicarbonate; if respiratory failure, acute renal failure treatment is more complex, may use ventilator treatment, dialysis treatment and other measures. If you have low bicarbonate, it is recommended that you consult a doctor to determine the cause of the problem before giving appropriate treatment.
