Many of you may be familiar with the same thing.an unpleasant feeling, when we do not have breakfast, we start eating at lunchtime, but instead of experiencing hunger, we often feel nausea and dizziness at this moment. Why is this happening? Why does our body make food less attractive at the moment when it needs energy most?
Why does dizziness occur during fasting?
According to the portal livescience.com, dizziness during fasting occurs due to the fact that a person’s stomach produces hydrochloric acid to better break down food during digestion. Accumulating in the stomach, acid enters the esophagus, causing a gag reflex, heartburn, and even nausea. Another possible cause of nausea during hunger can be directly related to a network of signals within the human body that are regulated by the endocrine system, pituitary gland and pancreas.
Hormones produced by the endocrine system,give the body the information necessary to maintain a balanced level of chemicals. So, a healthy blood sugar level is maintained thanks to the signals of the stomach into the endocrine system, which triggers the release of hormones responsible for the feeling of hunger. The most important of these can be considered ghrelin and leptin.
The hormone ghrelin is responsible for the feeling of hunger,regulating many important processes in the body, which include intestinal motility, secretion of gastric acid, taste sensations and glucose metabolism. Leptin, in turn, has the opposite effect: it counteracts ghrelin, reducing appetite. When you eat, your body releases a large amount of leptin, signaling that your body is satisfied with the amount of food provided to it, and now you can feel full for some time. Sometimes the chemical balance of the body can be disturbed if for some reason we ignore the signals of hunger for a long time.
