What is acid-base balance?

Acid-base balance is a fundamental concept in biochemistry and medicine that describes the balance between acids and bases in the human body. This balance is crucial for maintaining blood pH within a narrow range of 7.35 to 7.45, which is essential for the optimal functioning of various enzymatic and metabolic systems.

How does the body regulate acid-base balance?

The body has three main mechanisms for regulating this balance:

1. Chemical buffers: These substances can rapidly neutralize excess acids or bases. Bicarbonate (HCO3-) is a major buffer in the blood.
2. Breathing: Increasing or decreasing respiratory rate can adjust CO2 levels, which combine with water to form carbonic acid (H2CO3), thus influencing blood pH.
3. Kidney function: The kidneys exert long-term control over acid-base balance by excreting acid ions or retaining bicarbonates as required.

What are the most common acid-base imbalances?

The two main types of imbalance are :

• Acidosis: This occurs when the body accumulates too much acid or loses too much base, which may be due to respiratory or metabolic problems, or kidney failure.
• Alkalosis: This occurs when the body accumulates too many bases or loses too many acids, often due to excessive vomiting, diuretics or abnormal hormones.

How are acid-base disorders diagnosed?

Diagnosis of acid-base disorders generally involves :

• Blood tests: Measurement of pH, bicarbonate (HCO3-) and total CO2.
• Arterial blood gas: Provides an accurate measure of acidity and carbon dioxide in the blood.

What impact does diet have on acid-base balance?

Diet can have a significant influence on acid-base balance. Foods such as meat, cereals and cheeses are considered acidifying, while fruit and vegetables are often seen as alkalizing. A balanced diet, rich in fruit and vegetables, can help maintain an optimal pH in the body.

What are the long-term consequences of acid-base imbalance?

Prolonged imbalance can lead to a number of complications, including

• Deterioration of bone health
• Reduced muscle function
• Impaired kidney function
• Impaired cardiac function

How can we maintain a healthy acid-base balance?

Maintaining a healthy balance often requires :

• Adequate hydration: Drinking enough water helps dilute excess acids.
• Balanced diet: Adopt a diet rich in alkalizing foods.
• Regular exercise: Physical activity helps breathing and kidney function.

What is the relationship between acid-base balance and chronic fatigue?

Acid-base balance can play a significant role in the phenomenon of chronic fatigue. Prolonged imbalance, particularly acidosis, can lead to reduced energy and increased fatigue, as cells do not function at their optimum level in an overly acidic environment. Regulating pH through proper nutrition and hydration is therefore essential for those suffering from chronic fatigue.

How does acid-base balance affect mental health?

Research suggests that acid-base balance can influence mental health. An imbalance, particularly acidosis, can affect brain function, potentially disrupting neurotransmission and increasing the risk of disorders such as depression or anxiety. A balanced diet, enriched with alkalizing nutrients, can help preserve good mental health.

What tests can identify an acid-base imbalance?

Several tests can be used to identify an acid-base imbalance:

• Urine pH: A quick and easy indicator to measure at home, which can give a general indication of acid-base balance.
• Blood gas analysis: Provides an accurate picture of blood pH, CO2 and bicarbonate levels, indicating the presence of acidosis or alkalosis.
• Serum electrolytes: Measures levels of sodium, potassium and chlorine, all of which can be affected by changes in acid-base balance.

How do drugs affect acid-base balance?

Certain medications can have a significant impact on acid-base balance:

• Diuretics: Can cause alkalosis by inducing excessive loss of acidic electrolytes.
• Steroids and anti-inflammatory agents: Can contribute to acidosis by affecting metabolism and renal function. It is crucial to discuss the effects of these drugs on acid-base balance with a healthcare professional.

What nutritional strategies do you recommend to optimize acid-base balance?

To optimize acid-base balance through nutrition, here are some strategies:

• Increase consumption of green vegetables and fruit, which are rich in alkalizing minerals such as potassium and magnesium.
• Reduce consumption of animal proteins, dairy products and processed foods, which can increase acidity.
• Include calcium-rich foods such as almonds and broccoli, which can help neutralize acids.
• Drink alkaline water or add lemons or baking soda to water to increase its alkalinity.
