Your Body's pH Balance Regulator
Your Body's pH Balance Regulator
Your Body's pH Balance Regulator
Every moment of your life, your body produces acids through normal cellular processes like energy production and waste removal, creating the constant need for a buffering system that prevents these acids from making your blood dangerously acidic. Bicarbonate works as your body's primary acid neutraliser, maintaining the precise pH balance your enzymes, organs, and cellular processes need to function properly.
Think of bicarbonate as your body's internal chemistry teacher, constantly working to keep your blood at just the right acidity level. Just as a chemistry lab needs careful pH control for experiments to work properly, your body needs bicarbonate to maintain the exact chemical environment that allows all your vital processes to function smoothly.

When Bicarbonate Levels Fall Out of Balance
Normal bicarbonate levels indicate that your body's pH regulation system is working properly, maintaining the precise chemical balance your cells need to function optimally. When levels are in the healthy range of 22-32 mmol/L, it suggests your kidneys, lungs, and buffering systems are successfully coordinating to keep your blood chemistry stable.
Low bicarbonate levels indicate metabolic acidosis, where your body either has too much acid or is losing bicarbonate faster than it can be replaced. You might feel fatigued, confused, or short of breath as your body struggles to maintain the chemical balance needed for normal cellular function. Your breathing may become faster and deeper as your lungs try to help by eliminating excess acid through increased carbon dioxide elimination.
This type of imbalance can develop from several causes: kidney disease that prevents proper acid elimination, diabetes complications that produce ketones (acidic substances), severe diarrhoea that removes bicarbonate-rich fluids from your intestines, or certain medications that affect your body's acid production or elimination.
High bicarbonate levels suggest metabolic alkalosis, where your blood has become too alkaline. This condition often results from excessive acid loss through prolonged vomiting, overuse of diuretics (water pills), or conditions that cause your kidneys to retain too much bicarbonate. Symptoms can include muscle cramps, tingling sensations, confusion, or irregular heart rhythms as your body's enzymes struggle to function in the overly alkaline environment.
The severity of symptoms often depends on how quickly these changes occur. Rapid shifts in bicarbonate levels can cause more dramatic symptoms than gradual changes, as your body has less time to activate its natural compensation mechanisms.

What Influences Your Bicarbonate Levels
Your kidneys play the most crucial role in maintaining bicarbonate balance, as they both produce bicarbonate and control how much your body retains or eliminates. When kidney function declines, acid can accumulate whilst bicarbonate is lost, creating a cycle where metabolic acidosis gradually worsens without medical intervention.
Digestive problems can significantly disrupt bicarbonate levels through different mechanisms. Severe diarrhoea removes bicarbonate directly from the intestine, leading to acidosis. Conversely, prolonged vomiting eliminates stomach acid and can lead to alkalosis. The location and duration of these digestive losses determine whether your bicarbonate levels become too low or too high.
Your breathing patterns and lung function indirectly affect bicarbonate through their control of carbon dioxide levels. Lung diseases that prevent adequate CO2 elimination can contribute to acidosis, whilst rapid breathing from anxiety, pain, or other causes can create alkalosis by removing too much CO2 from your system. Significant differences in bicarbonate due to breathing however usually require medical assessment.
Medications can influence bicarbonate through various pathways. Diuretics might cause imbalances by promoting acid loss, certain diabetes medications could contribute to acidosis, and treatments that affect kidney function can alter your body's bicarbonate handling. Even some antacids, when used excessively, can affect your acid-base balance.

How to Support Healthy Bicarbonate Level
Since bicarbonate levels primarily reflect your body's overall acid-base balance and organ function, supporting healthy levels focuses on addressing underlying causes.
If your bicarbonate imbalance is related to kidney disease, working closely with your healthcare team becomes essential. This typically involves managing conditions like diabetes or high blood pressure that can damage kidneys over time, adjusting medications that might affect kidney function, and sometimes taking prescribed medications specifically designed to help your body maintain proper acid-base balance.
Proper hydration supports your kidneys' ability to regulate bicarbonate and maintain acid-base balance.

Understanding Your Bicarbonate Results
Normal levels: 22-32 mmol/L
Low bicarbonate levels (below 22 mmol/L) suggest metabolic acidosis, where your body has too much acid or is losing too much bicarbonate. Mild decreases might indicate early kidney problems or dietary factors, whilst significantly low levels often point to more serious conditions requiring prompt medical attention.
High bicarbonate levels (above 32 mmol/L) indicate metabolic alkalosis, where your blood has become too alkaline. Mild elevations might result from medication effects or minor digestive issues, whilst substantially high levels suggest more significant underlying problems that need investigation and treatment.
Your doctor will typically evaluate bicarbonate alongside other electrolytes like sodium, potassium, and chloride, as well as kidney function tests, to get a complete picture of your body's chemical balance. They might also calculate something called the "anion gap," which helps identify specific causes of acid-base disorders.
The pattern of your results over time is often more informative than a single measurement. Trending bicarbonate levels help your healthcare team assess whether treatments are working and whether your underlying condition is stable, improving, or worsening.
