Brief Answer:
About hunger hormones;

Detailed Answer:
Hello and thank you for asking!
The concept of hunger and fullness of the stomac is complex and regulated by 3 main hormones; Leptin, ghrelin and neuropeptid y.
Leptin tells your brain that you’re full and you don’t need to eat more.
Ghrelin is an appetite-inducing hormone and when its levels are high, you crave something sweet, which after you eat will help lower your “Growling Ghrelin” level.
NPY’s primary job is to delay the feeling of fullness throughout a meal. In other words, high NPY levels will decrease the feeling of fullness from a meal.
When this circle is disorganised (for many reasons) there is a change in your hunger, feeling of fullness ect.
Usually the last result is weight gain.
The weight gain causes a vicious cycle and a further disorganization of this ''orchestra''.
So you should do the utmost to prevent it.
Hope the information will help.
Best wishes,

Are there any other reasons cause such no feeling?Before I lost my feeling, I used to feel uncomfortable about my stomach. Now, even in the same situation that I know my stomach must feel uncomfortable according to the experiences before, I can feel nothing. And if it is NPY, what will trigger it become so high?By the way, I have anxiety since Feb. Is that might a reason?Actually, not only the feeling of hunger and fullness, the feeling of anxiety weakened a lot in my brain even if I know I am experiencing nervous right now. It feels like my brain is kind of blind. Thank you for your patient answering!
I appreciate it

Brief Answer:
Anxiety and ghrelin

Detailed Answer:
Welcome back!

Science studies have found a relationship between anxiety/depression and ghrelin level.
In these situations, ghrelin levels are found to be high and causes hunger and weight gain.
On the other side, these high ghrelin levels improve the anxiety and cause a neutral feeling like that you described.

So, of course the situation you experienced months ago is responsible for this hormonal ''game''.

What should you do now?
Try to defeat the hunger and avoid stressful situations.

Wish you good health.
