Because hormones affect so many different aspects of how our bodies operate, the outward symptoms tend to be varied and nonspecific. It may feel as though you are simply tired or upset after an unusually stressful or busy week. With a hormonal imbalance, a person may suffer from anxiety, insomnia, loss of appetite, and poor concentration. Irritability and mood swings are also quite common. Hormonal balance is critical for our emotional well-being, so radical changes in the way we feel about ourselves and interact with others may indicate a problem.
The endocrine system is in charge of body processes that happen slowly, such as cell growth. Faster processes like breathing and body movement are controlled by the nervous system. But even though the nervous system and endocrine system are separate systems, they often work together to help the body function properly.
The foundations of the endocrine system are the hormones and glands. As the body's chemical messengers, hormones transfer information and instructions from one set of cells to another.
