📚 Understanding Acidosis vs. Alkalosis
Acidosis and alkalosis are conditions characterized by an imbalance in the body's acid-base balance, specifically affecting the pH of the blood. Maintaining a stable pH is crucial for proper bodily functions, as enzymes and metabolic processes are sensitive to pH changes.
🧪 Definition of Acidosis
Acidosis is a condition in which there is too much acid in the body fluids. This means the blood pH is lower than the normal range (7.35 - 7.45).
- 🍎 Causes: Can be caused by respiratory problems (e.g., hypoventilation), kidney problems, severe diarrhea, diabetes, and certain medications.
- 📈 pH Level: Blood pH is less than 7.35.
- ❗ Symptoms: Symptoms may include rapid and shallow breathing, confusion, fatigue, headache, and in severe cases, coma.
🔬 Definition of Alkalosis
Alkalosis is a condition in which there is too much base (alkali) in the body fluids. This results in a blood pH higher than the normal range (7.35 - 7.45).
- 💧 Causes: Can be caused by hyperventilation, vomiting, certain kidney diseases, and excessive intake of alkaline substances (e.g., antacids).
- 📉 pH Level: Blood pH is greater than 7.45.
- ⚠️ Symptoms: Symptoms may include muscle twitching, numbness or tingling, dizziness, lightheadedness, and in severe cases, seizures or coma.

🔑 Key Takeaways
- 🌡️ pH Scale: The pH scale ranges from 0 to 14, with 7 being neutral. Values below 7 are acidic, and values above 7 are alkaline.
- ⚖️ Balance: Maintaining a proper acid-base balance is crucial for optimal health and bodily functions.
- 🩺 Medical Attention: Both acidosis and alkalosis can be serious conditions and require prompt medical evaluation and treatment.
- 💡 Compensation: The body has mechanisms to compensate for pH imbalances, but these can be overwhelmed.
- 🧬 Buffers: Buffers in the blood help to resist changes in pH. A primary buffer system is the bicarbonate buffer system: $CO_2 + H_2O \rightleftharpoons H_2CO_3 \rightleftharpoons H^+ + HCO_3^-$.
