Why do I get hungry easily?
I usually eat quite a lot during each meal, sometimes even eating until I'm very full. However, I often feel hungry again shortly after eating—usually within less than three hours. Doctor, why do I feel hungry so easily?

Frequent hunger may be related to fluctuations in blood glucose levels. When blood sugar levels drop, the brain receives signals and triggers hunger to prompt the individual to eat and replenish energy.
If the diet is unbalanced, such as excessive consumption of high-sugar, high-fat, and low-fiber foods, it can cause a rapid increase in blood sugar levels followed by a sharp decline, leading to frequent hunger. In addition, endocrine disorders such as hyperthyroidism and insulin resistance may also cause persistent hunger.
A deficiency in key nutrients, such as protein, dietary fiber, and healthy fats, may also contribute to frequent hunger. These nutrients help prolong the feeling of fullness and stabilize blood sugar levels. For example, dietary fiber increases the retention time of food in the gastrointestinal tract and slows down the absorption of sugars, thereby preventing sudden spikes and drops in blood sugar that can cause hunger.
If frequent hunger occurs often, it is recommended to seek medical attention promptly. At the same time, maintaining healthy eating habits and a healthy lifestyle can also help prevent and alleviate symptoms of frequent hunger.
