It's common to experience increased urination during a fast, especially in the initial stages.
Here's why:
- Fluid Shifts: When you fast, your body starts breaking down stored glycogen (sugar) for energy. This process releases water, leading to increased urination.
- Electrolyte Changes: Fasting can affect electrolyte balance, particularly sodium levels. This can trigger the kidneys to excrete more water.
- Reduced Insulin: Insulin helps your body retain water. During fasting, insulin levels drop, causing a decrease in water retention and increased urination.
Important Note: If you experience excessive urination, particularly accompanied by other symptoms like extreme thirst, fatigue, or dizziness, consult a healthcare professional. It could be a sign of dehydration or other underlying health issues.
