Why does hunger cause nausea sometimes?

You get up late, you rush out of the house, and as soon as you enter the office the meeting starts, and the hunger is supposed to start, you don't have breakfast, and by the time you sit down for lunch you have almost 15 hours since your last meal, then you should be hungry, but instead, You feel nauseous.

 

How could that be? Why does your fasting body make food less attractive when you need it most? One of the most common reasons for this phenomenon is easy to understand, said Kristen Lee, a gastroenterologist at the Cleveland Clinic, as your stomach produces hydrochloric acid as part of the long process of breaking down food, to use what it can for energy and substances and get rid of the rest if you haven't eaten for a long time. Over time, hydrochloric acid can build up in the stomach, and when hydrochloric acid flows into the esophagus, it can cause gastroesophageal reflux disease, heartburn, and nausea, she said.

 

Another set of possible causes of feeling sick is when hunger relates to your body's signaling network of when to eat. These signals are regulated by the endocrine system, a system of glands (including the pituitary, thyroid, and pancreas) that uses the bloodstream for chemical communication.

Hunger

The hormones produced by the endocrine system give your body the information it needs to keep its chemical levels in balance. For example, to maintain healthy blood sugar levels and support a wide range of bodily activities you need calories Your stomach sends signals to the endocrine system that trigger the release of hormones. And these hormones tell the brain, give us more calories or that's enough. There are a lot of hormones, but two important players are ghrelin and leptin.

 

Ghrelin is supposed to cause hunger, she told me. The hormone was discovered in 1999, but since then researchers have identified ghrelin as a key player in a number of important processes in the body, including bowel movement, gastric acid secretion, the sense of taste, and glucose metabolism.

 

Leptin has the opposite effect, it counteracts ghrelin by decreasing appetite, and there are many other hormones involved in feeling hungry, but the interaction between ghrelin and leptin is key in the healthy tides and flow of appetite, and he told me when your body is in a normal state, these hormones It regulates itself automatically, you should just have a few cues throughout the day to gently remind you to eat.

 

While eating, your body releases leptin, which indicates that you are satisfied and do not need to be hungry for a while, in other words, your body needs food, so it produces ghrelin, and this makes you feel hungry, so you eat, then, your body does not need more food, so it produces leptin, and this makes you feel full, so you stop eating, but this chemical balance process can be thrown off if you ignore your hunger cues and don't eat regularly, just stay long enough without eating, and your body will try to convince you to eat by producing more ghrelin.

 

And she said to me when hormones go up, your hunger is supposed to go up and your appetite goes up, and most people most of the time, that's exactly what they do, but not always, and some people are more sensitive to hormonal levels, and she said to me, the difference in sensitivity and other factors that lead some people They may feel mild nausea when they are very hungry, however, more severe cases of nausea symptoms can indicate a disorder.

 

If your signals are severe enough that you become nauseated or in pain, your body may be telling you to check for metabolic syndrome, conditions such as high blood sugar, abnormal cholesterol, and increased blood pressure, which can lead to heart disease.
