You shake when you're hungry primarily because your blood sugar levels have dropped too low. This is known as hypoglycemia.
Understanding Hypoglycemia and Shaking
When you haven't eaten for a while, your body's glucose supply, which fuels your cells, starts to dwindle. This triggers several physiological responses designed to restore balance. One of the common warning signs of low blood sugar (hypoglycemia), as noted in the provided reference, is shaking or trembling. The reference highlights that symptoms typically appear when blood sugar levels fall below four millimoles (mmol) per litre.
How Blood Sugar Levels Affect You
The body depends on glucose for energy. When glucose levels decline, your brain and muscles start to feel the effects.
Here's a breakdown:
- Reduced Glucose: When you're hungry, your glucose levels decrease.
- Hormonal Response: Your body releases hormones like adrenaline to try and boost glucose levels. This can cause physical symptoms.
- Nervous System Activation: This hormonal response also activates the sympathetic nervous system, leading to physical manifestations like tremors and shaking.
Common Symptoms of Low Blood Sugar
The reference describes the following as typical early warning signs:
- Hunger: A strong feeling of needing food.
- Trembling or Shakiness: Involuntary shaking, especially in your hands.
- Sweating: An increase in perspiration.
Additionally, you might experience:
- Confusion
- Difficulty concentrating
Practical Steps to Address Shaking From Hunger
- Eat Something Quickly: Consume a small snack containing sugar and carbohydrates, such as fruit, crackers, or juice to restore blood glucose rapidly.
- Balanced Meal: Follow up with a more substantial, balanced meal containing complex carbohydrates, protein, and fats. This will provide a more sustainable energy source.
- Regular Meals: Avoid prolonged periods without eating. Try to have regular meals and snacks throughout the day to maintain stable blood sugar levels.
| Symptom | Cause | Solution |
|---|---|---|
| Shakiness | Low blood sugar (below 4 mmol/litre) | Eat a sugary snack; follow with a balanced meal |
| Hunger | Body signalling need for energy | Eat regularly to prevent hunger |
| Sweating | Hormonal response to low blood sugar | Maintain stable blood sugar level |
By understanding the mechanism behind shaking from hunger, you can effectively manage it and take the appropriate steps to maintain stable energy levels.
