How Can I Help Keep My Endocrine System Healthy?

<h3>What Is the Endocrine System?</h3>The endocrine system is made up of glands that make hormones. Hormones are the
 body's chemical messengers. They carry information and instructions from one set of
 cells to another.The endocrine (pronounced: EN-duh-krin) system influences almost every cell, organ,
 and function of our bodies.<h3>What Does the Endocrine System Do?</h3><UL><LI>Endocrine glands release <a onmouseover="doTooltip(event,msg_hormones_T)" onfocus="doTooltip(event,msg_hormones_T)" onmouseout="hideTip()" onblur="hideTip()" href="https://kidshealth.org/en/teens/endocrine.html#" aria-disabled="true" aria-describedby="msg_hormones_T" data-left="276.390625" data-top="353.78125" dir="ltr">hormones</a>

 , and reproduction.</LI><LI>The endocrine system regulates how much of each hormone is released. This can
 depend on levels of hormones already in the blood, or on levels of other substances
 in the blood, like calcium. Many things affect hormone levels, such as stress, infection,
 and changes in the balance of fluid and minerals in blood.</LI></UL>Too much or too little of any hormone can harm the body. Medicines can treat many
 of these problems.<h3>What Are the Parts of the Endocrine System?</h3>While many parts of the body make hormones, the major glands that make up the endocrine
 system are the:<UL><LI>hypothalamus</LI><LI>pituitary</LI><LI>thyroid</LI><LI>parathyroids</LI><LI>adrenals</LI><LI>pineal body</LI><LI>the ovaries</LI><LI>the testes</LI></UL>The pancreas is part of the endocrine system and the <a href="https://kidshealth.org/en/teens/digestive-system.html" dir="ltr">digestive
 system</a>. That's because it secretes hormones into the bloodstream, and makes and
 secretes enzymes into the digestive tract.Hypothalamus: The hypothalamus (pronounced: hi-po-THAL-uh-mus)
 is in the lower central part of the <a href="https://kidshealth.org/en/teens/brain-nervous-system.html" dir="ltr">brain</a>.
 It links the endocrine system and nervous system. Nerve cells in the hypothalamus
 make chemicals that control the release of hormones secreted from the pituitary gland.
 The hypothalamus gathers information sensed by the brain (such as the surrounding
 temperature, light exposure, and feelings) and sends it to the pituitary. This information
 influences the hormones that the pituitary makes and releases.Pituitary: The pituitary (pronounced: puh-TOO-uh-ter-ee) gland
 is at the base of the brain, and is no bigger than a pea. Despite its small size,
 the pituitary is often called the "master gland." The hormones it makes
 control many other endocrine glands.The pituitary gland makes many hormones, such as:<UL><LI>growth hormone, which stimulates the growth of bone and other body tissues and
 plays a role in the body's handling of nutrients and minerals</LI><LI>prolactin (pronounced: pro-LAK-tin), which activates milk production in women
 who are breastfeeding</LI><LI>thyrotropin (pronounced: thy-ruh-TRO-pin), which stimulates the thyroid gland
 to make thyroid hormones</LI><LI>corticotropin (pronounced: kor-tih-ko-TRO-pin), which stimulates the adrenal gland
 to make certain hormones</LI><LI>antidiuretic (pronounced: an-ty-dy-uh-REH-tik) hormone, which helps control body
 water balance through its effect on the <a href="https://kidshealth.org/en/teens/kidneys.html" dir="ltr">kidneys</a></LI><LI>oxytocin (pronounced: ahk-see-TOE-sin), which triggers the contractions of the
 uterus that happen during labor</LI></UL>The pituitary also secretes endorphins (pronounced: en-DOR-fins), chemicals that
 act on the nervous system and reduce feelings of pain. The pituitary also secretes
 hormones that signal the reproductive organs to make sex hormones. The pituitary gland
 also controls <a onmouseover="doTooltip(event,msg_ovulation_T)" onfocus="doTooltip(event,msg_ovulation_T)" onmouseout="hideTip()" onblur="hideTip()" href="https://kidshealth.org/en/teens/endocrine.html#" aria-disabled="true" aria-describedby="msg_ovulation_T" data-left="471.90625" data-top="1551.171875" dir="ltr">ovulation</a>
 and the menstrual cycle in women.Thyroid: The thyroid (pronounced: THY-royd) is in the front part
 of the lower neck. It's shaped like a bow tie or butterfly. It makes the thyroid hormones
 thyroxine (pronounced: thy-RAHK-sin) and triiodothyronine (pronounced: try-eye-oh-doe-THY-ruh-neen).
 These hormones control the rate at which cells burn fuels from food to make energy.
 The more thyroid hormone there is in the bloodstream, the faster chemical reactions
 happen in the body.Thyroid hormones are important because they help kids' and teens' bones grow and
 develop, and they also play a role in the development of the brain and nervous system.Parathyroids: Attached to the thyroid are four tiny glands that
 work together called the parathyroids (pronounced: par-uh-THY-roydz). They release
 parathyroid hormone, which controls the level of calcium in the blood with the help
 of calcitonin (pronounced: kal-suh-TOE-nin), which the thyroid makes.Adrenal Glands: These two triangular adrenal (pronounced: uh-DREE-nul)
 glands sit on top of each kidney. The adrenal glands have two parts, each of which
 makes a set of hormones and has a different function:<OL><LI>The outer part is the adrenal cortex. It makes hormones called
 corticosteroids (pronounced: kor-tih-ko-STER-oydz) that help control salt and water
 balance in the body, the body's response to stress, metabolism, the <a href="https://kidshealth.org/en/teens/immune.html" dir="ltr">immune
 system</a>, and sexual development and function.</LI><LI>The inner part is the adrenal medulla (pronounced: muh-DUH-luh).
 It makes catecholamines (pronounced: kah-tuh-KO-luh-meenz), such as epinephrine (pronounced:
 eh-puh-NEH-frun). Also called adrenaline, epinephrine increases blood pressure and
 heart rate when the body is under stress.</LI></OL>Pineal: The pineal (pronounced: pih-NEE-ul) body, also called
 the pineal gland, is in the middle of the brain. It secretes melatonin (pronounced:
 meh-luh-TOE-nin), a hormone that may help regulate when you sleep at night and when
 you wake in the morning.Reproductive Glands: The gonads are the main source of sex hormones.
 Most people don't realize it, but both guys and girls have gonads. In guys the <a href="https://kidshealth.org/en/teens/male-repro.html" dir="ltr">male gonads</a>, or testes (pronounced: TES-teez),
 are in the scrotum. They secrete hormones called androgens (pronounced: AN-druh-junz),
 the most important of which is <a onmouseover="doTooltip(event,msg_testosterone_P)" onfocus="doTooltip(event,msg_testosterone_P)" onmouseout="hideTip()" onblur="hideTip()" href="https://kidshealth.org/en/teens/endocrine.html#" aria-disabled="true" aria-describedby="msg_testosterone_P" data-left="206" data-top="2328.171875" dir="ltr">testosterone</a>
 (pronounced: tess-TOSS-tuh-rone). These hormones tell a guy's body when
 it's time to make the changes associated with puberty, like penis and height growth,
 deepening voice, and growth in facial and pubic hair. Working with hormones from the
 pituitary gland, testosterone also tells a guy's body when it's time to make sperm
 in the testes.A <a href="https://kidshealth.org/en/teens/female-repro.html" dir="ltr">girl's gonads</a>, the ovaries (pronounced:

 (pronounced: pro-JESS-tuh-rone). Estrogen is involved when a girl starts
 <a href="https://kidshealth.org/en/teens/puberty.html" dir="ltr">puberty</a>. During puberty, a girl will have breast
 growth, start to accumulate body fat around the hips and thighs, and have a growth
 spurt. Estrogen and progesterone are also involved in the regulation of a girl's <a href="https://kidshealth.org/en/teens/menstruation.html" dir="ltr">menstrual cycle</a>. These hormones also play a
 role in pregnancy.Pancreas: The pancreas (pronounced: PAN-kree-us) makes <a href="https://kidshealth.org/en/teens/insulin.html" dir="ltr">insulin</a>
 (pronounced: IN-suh-lin) and <a href="https://kidshealth.org/en/teens/glucagon-def.html" dir="ltr">glucagon</a> (pronounced:
 GLOO-kuh-gawn), which are hormones that control the level of <a href="https://kidshealth.org/en/teens/glucose.html" dir="ltr">glucose</a>,
 or sugar, in the blood. Insulin helps keep the body supplied with stores of energy.
 The body uses this stored energy for exercise and activity, and it also helps organs
 work as they should.<h3>How Can I Help Keep My Endocrine System Healthy?</h3>To help keep your endocrine system healthy:<UL><LI>Get plenty of <a href="https://kidshealth.org/en/teens/exercise-wise.html" dir="ltr">exercise</a>.</LI><LI>Eat a nutritious diet.</LI><LI>Go for regular medical checkups.</LI><LI>Talk to the doctor before taking any supplements or herbal treatments.</LI><LI>Let the doctor know about any family history of endocrine problems, such as <a href="https://kidshealth.org/en/teens/center/diabetes-center.html" dir="ltr">diabetes</a> or <a dir="ltr">thyroid
