How does overeating affect our body?

Overeating is always accompanied by a feeling of heaviness in the upper abdomen, nausea, bloating, and difficulty breathing. But how does overeating affect us in the long run?

Impaired control of hunger

Consuming sugar, salt, and high-fat foods triggers the production of pleasure hormones. Over time, the body can associate food with pleasure and we begin to eat not to satisfy hunger, but to feel "happy." This in turn leads to endless overeating.


When we consume more calories than we spend, we get an overabundance of them. The body can store these extra calories in the form of fat. Obesity multiplies the risk of cardiovascular disease, hypertension and other problems. U.S. doctors from the Centers for Disease Control and Prevention have linked obesity to 13 types of cancer. According to the researchers, weight loss can reduce the risk of them occurring.

To get energy from carbohydrates, our body converts them into glucose. The hormone insulin is responsible for its assimilation. But if it ceases to function properly, or if cells stop taking it in, sugar builds up in the blood, leading to diabetes. It is important to eat at regular intervals to avoid overeating. Constant overeating can be a significant cause of diabetes.

Brain function

One study involving older adults found that being overweight has a negative effect on memory compared to people of normal weight. According to it, consuming more than 2,400 calories a day can double the risk of memory loss or cause moderate cognitive impairment in people age 70 and older.


Drowsiness after a meal may be due to the fact that blood sugar levels soon drop. The cause is thought to be related to overproduction of insulin.
Low blood sugar levels are usually associated with drowsiness, lethargy, palpitations, and headaches.

Don't berate yourself for overeating once in a while, but if it becomes a habit, talk to your doctor, who can help you identify the underlying causes and offer a solution.
