Hormones and The Human Body
Hormones are chemical messengers/drivers that are released from glands into blood that travel between cells. They are released in one part of the body, travel in the blood stream and have an effect on other parts of the body. This helps different parts of the human body to communicate with each other.
Hormones are secreted by endocrine glands, such as the pituitary, thyroid or adrenal glands.
Hormones are found in all organisms with more than one cell, hence they are also found in plants and animals.
They influence or control a wide range of physiological activities, such as growth, development, puberty, level of alertness, sugar regulation, bone growth and appetite.
Diabetes is one the most common hormonal disorders, occurring when the pancreas secretes too little insulin, the hormone which manages blood sugar levels.
Hypothyroidism and hyperthyroidism are conditions of the thyroid which occur when the thyroid gland make too little or too much thyroid hormones.
A wide and varied range of substances are thought to cause endocrine disruption. Chemicals that are known endocrine disruptors include diethylstilbestrol (the synthetic estrogen DES), dioxin and dioxin-like compounds, polychlorinated biphenyls (PCBs), DDT, and some other pesticides.
Adverse effects of these chemicals include;
•Male and female infertility.
•Female reproductive toxicity.
•Birth and pregnancy complications.
•Skin irritation, itchiness, or rash.
