Why am I hungry when I m full? Why do you feel hungry just after eating?

The reason is that after eating too much, after the food almost enters the small intestine, the stomach that was originally very full suddenly becomes empty, and the nerves in the stomach transmit to the brain and there is an error signal of hunger. After the signal is wrong, it will lead to the secretion of gastric acid, the secretion of digestive proteins in the stomach.

The most direct cause of hunger is a decrease in blood sugar concentration, but there can be a variety of causes.

First: there is a problem with the blood. Some people's blood glucose concentration will be lower than normal due to characteristic (genetic) reasons, and the result is that they are hungry all the time, and they will not feel comfortable eating until they are struggling, and they are weaker and have weak immunity, and they may often get sick and have no strength.

Go for a blood test) The second is that the digestive tract is not functioning well, and if the digestive organs such as the small intestine and stomach cannot work normally, they will not be able to completely convert the food into the nutrients needed by the body, resulting in low blood sugar concentration, and it is easy to get hungry, and you will be hungry soon after eating. (Go for a gastrointestinal examination, even the mouth, esophagus, gall bladder, etc.).

The third type: it may also be caused by more thyroid hormone secretion, which will be very thin and short-tempered (commonly known as hyperthyroidism, it is recommended to go to the hospital to test the thyroid gland).

Fourth: hunger will not be unbearable, is "annoying hunger", may be abnormal liver function, when the blood sugar concentration is reduced, the liver can not make a correct physiological response, to decompose liver glycogen to maintain normal activity energy, so continue to consume a small amount of glycogen in the blood, resulting in heavier and heavier physiological reactions. (hungry, annoyingly hungry).

It is recommended to check the liver and gallbladder function, the role of the gallbladder is also very large, even if the liver function is normal, if the bile function is not normal, the fat can not be converted into energy substances normally, and it will also lead to the same consequences, but people will gain weight and cannot eat greasy things].

Fifth: There may be a problem with the kidneys, the nutrients have to be filtered by the kidneys, and if there is a problem with the kidneys, the nutrients cannot enter the blood circulation normally. As a result, the body is always in a state of insufficient nutrition, and it is manifested as hunger.

It is recommended to check kidney function, renal tubules and filter, which may lead to diabetes. People will be thinner, not good, have rashes, etc., and the urine color is not normal).

Sixth: It may be a combination of the above reasons. Human beings are very sophisticated and advanced instruments, and often when there is relatively small damage, it can rely on its own physiological response to adjust and prompt.

So when you feel very uncomfortable, your body function has decreased a lot, so sometimes the causes of a condition are often a mixture of several things.

The center of the human body feeling hungry is in the brain stem, if you feel hungry all the time and can't eat enough, go to the neurology department for a checkup. If you feel full during a meal, but you are hungry after a while, and sometimes you feel more hungry than before eating, it is recommended that you check your blood sugar, it may be that you have hypersecretion of insulin. I don't know if you're fat or not, and if you eat too much.

Hello, is this often the case? Inference: one is abnormal blood sugar, the second is a thyroid problem, and the third is a digestive disorder.

It means that you have been hungry for too long and have stomach problems.

I have a little bit of stomach problems, and I feel that way too.
