Hunger pangs, or hunger pains, are a natural reaction to an empty stomach. They cause a gnawing feeling or an empty sensation in the abdomen.
But hunger pangs can happen even if the body does not need food. Several other situations and conditions can lead to hunger pangs, including:
- sleep deprivation
- dehydration
- eating the wrong foods
What are the causes?
People get hunger pangs or hunger pains for several different reasons. Seven reasons are explained here:
1. Hunger hormone
The brain triggers the release of a hormone called ghrelin in response to an empty stomach or in anticipation of the next meal.
Ghrelin signals the body to release stomach acids to digest food. If food is not consumed, the stomach acids begin to attack the lining of the stomach, causing hunger pains.
Studies have shown that ghrelin increases hunger by up to 30 percent when it is administered to adults.
2. Quality of food eaten
Hunger pangs can happen even when the body does not need calories.
This is because ghrelin interacts with insulin, the hormone that regulates blood sugar. Falling levels of insulin cause ghrelin, and therefore hunger, levels to rise.
Junk food contains high amounts of sugar and simple carbohydrates. Eating it causes a spike in insulin levels, followed by a quick drop. Ghrelin then increases, even though the food was consumed only an hour or so beforehand.
In this way, eating even large amounts of poor quality food can increase hunger and cause the pang response in the body.
3. Dehydration
Many people cannot tell the difference between hunger and thirst because the symptoms are so similar.Thirst can cause symptoms, such as:
- stomach pains
- shaking
- irritability
- lightheadedness
4. The environment
Some people experience pangs in response to smells and sights. Many people have a physical response to the smell of freshly baked goods or cooking. Images of food on T.V. or online can also cause the mouth to water.
Although this type of hunger may not be based on a need for food, it causes very real physical symptoms, including hunger pains.
