However, just a refresher, what is the endocrine system?

Basics of the Endocrine System

The human body is made up of various systems. To help you cope with stresses and multiple events, the endocrine, immune and nervous system work together. Several glands located throughout your body, make up the endocrine system.

The hormones secreted by these glands regulate different activities of the body. It includes your metabolism, reproduction, sexual function, to mood. Produced and secreted by the organs, the hormones disperse throughout one’s body through the circulatory system.

In your personal statement internal medicine, you should know that these hormones work on tissues, cells and organs that are far from the gland that produces the hormone. The glands within this system can be categorised into two:

  1. Exocrine Glands: they secrete their hormones into ducts, directly
  2. Endocrine Glands: these glands secrete hormones directly into the bloodstream. From there, they get carried to the specific site of action.

Understanding the Endocrine System & Weight

Hormones play a vital role in our lives, and hormonal imbalance can affect your efforts to lose or gain weight. So, what are hormones you may ask? You can consider them as chemical messengers which transfer information from one cell to another, to bring a particular effect or change.

Each hormone, though it passes through the bloodstream, has a specific specialisation. That includes (not an exhaustive list):


It controls the level of blood sugar in the body. Insulin gets secreted as the body responds to increased blood glucose. Hyperinsulinemia is where the body has an excessive level of insulin in the blood.

Here, insulin fills up the fat cells. The more insulin is produced; the more fat you have.


When exposed to stress factors, this hormone gets released, say you get stressed by having to write an internal medicine residency personal statement. The trouble comes in when exposure to stress gets prolonged.

What follows is an excessive release of cortisol. The elevated cortisol and prolonged stress can lead to sleep deprivation and an excessive intake of food. Lack of sleep increases the secretion of cortisol.

It, in turn, reduces the release of leptin which results in elevation of insulin levels which translates into weight gain.


This hormone controls the expenditure of energy and its storage. It signals the hypothalamus that the body has adequate energy, stored as fat. Its effect determines whether the hypothalamus decides to suppress or stimulate your appetite.

When the leptin signal doesn’t work correctly, it may result in the increased release of insulin.

Disorders of the Endocrine System

Diminished or heightened levels of a particular hormone may lead to an endocrine disorder. It is as a result of your body not responding to a hormone, rightly. Many of them have a relationship to weight gain, including:

Iodine Deficiency

Iodine is essential for the body to produce the thyroid hormone which is responsible for the running of your metabolism. The body doesn’t provide enough iodine by itself. Therefore, it is essential to include it in your diet.

Without the right levels of iodine, you may suffer from hyperthyroidism. In that, you start to have a slow metabolism, which may result in gaining weight. It may also lead to the enlargement of the thyroid.


It occurs when the body doesn’t process glucose correctly. It is a common endocrine disorder, especially in the US. In those with diabetes, thyroid disorders are the most common.

To help regulate your body; it is essential to check your levels of the thyroid hormone, regularly.


For any human body, weight loss depends on hormonal balance. This balance relies on the endocrines system response to the needs of your body. Having endocrine disorders isn’t the only basis of one’s weight problems, in any case.

A balanced diet can help you correct some of the endocrine disorders. However, you still need to consider all other factors that may affect your metabolism. That includes the quality of sleep that you get, level of stress, and your attitude towards reaching an optimal weight.

You have to understand the cause of your weight troubles for you to treat it effectively. For an endocrine disorder or hormonal imbalance, you should talk to an expert endocrinologist.
