1 When the parts of the endocrine system shut down…

2 Remember that the endocrine system regulates…
* body energy levels * reproduction * growth and development * internal balance of body systems, called homeostasis * responses to surroundings, stress and injury

3 Disorders Endocrine system diseases and disorders happen when one or more of the endocrine systems in your body are not working well. These irregularities are also called a hormone imbalance. not be enough receptors, or binding sites, regulating the hormones in the blood stream, the body may have difficulty controlling hormone levels because of problems clearing hormones from the blood

4 Diabetes Too much sugar (glucose) in the blood stream
occurs when the pancreas does not produce the hormone insulin Insulin is necessary in carrying the sugar to the cells for cellular respiration If insulin is not present, sugar not converted into energy, thus metabolism cannot occu Symptoms of diabetes include fatigue, weight loss, blurred vision, excessive thirst, and excessive urination.

5 Growth disorders Growth and development controlled by the pituitary gland Growth Hormone (somatotropin) is release by the pituitary and controlled by the hypothalmus Bones, muscles, and other tissues are affected by GH In children: stimulates linear growth, or height development of muscle and bone distribution of body fat throughout the body In adults: affects energy, muscle strength, bone health, and psychological well being

6 Growth disorders continued…
too much GH = acromegaly (adults) caused by a non-cancerous pituitary gland tumor of the pituitary gland too much GH in children causes gigantism. Rare growth hormone deficiency (GHD) A child can be born with GHD. The condition also may arise because of damage to the hypothalamus or pituitary gland as a child or adult because of a tumor, an infection, or radiation to the brain — usually for the treatment of a tumor. A deficiency in GH may also have an undefined cause.

7 growth hormone deficiency (GHD)
Children grow less than two inches per year have extra fat in the abdomen and face blood sugar levels also may be low may experience emotional distress

8 Adults acquired the deficiency after reaching maturity
Increased body fat (particularly at the waist and in the face) Decreased muscle and bone mass Thinning skin with fine wrinkles Poor sweating or impaired temperature regulation Reduced strength and endurance Low energy level Decreased well-being (moodiness, mild depression) Loss of interest in sex Poor sleep Higher cholesterol levels, especially LDL (“bad”) cholesterol Overproduction of insulin

9 Reproductive Menopause - the ability to become pregnant ceases
May take 10 years to complete Average age range 47-55 Estrogen levels drop, egg release halts May be caused earlier due to Removal of ovaries Radiation/chemotherapy Gland disorders Severe illness

10 Osteoperosis a progressive condition in which bones become structurally weak and are more likely to fracture or break Bones in the hip, spine, and wrist are especially prone to fragility fractures Hormones that affect bone loss: Estrogen= protects bone Loss of testosterone excess cortisol = produced in the adrenal gland too much of the hormone prolactin high doses of thyroid hormone also have a higher risk.

11 pituitary gland pituitary tumors
can interfere with the normal formation and release of hormones. Two types of tumors exist - secretory and non-secretory Hypersecretion = too much hormone secreted Hyposecretion = too little hormone secreted Tumor mass effects = tumor presses against pituitary gland Headaches, hyposecretion related problems Caused by major head trauma or medications

12 Polycystic Ovary Syndrome PCOS
Ovaries produce small amounts of androgens to control egg release PCOS = too much of any type of androgen is produced Cysts (follicles), contain eggs and build up in the ovaries leading cause of infertility is likely that it is a genetic disorder

13 Thyroid Disorders Thyroid hormones regulate how the body breaks down food and either uses that energy immediately or stores it for the future Thyroid hormones influence virtually every organ system in the body. also regulate the consumption of oxygen and the production of heat

14 Hyperthyroidism Too much thyroid hormone from an overactive thyroid gland speeds up the body's metabolism 1% of women get it, more common in women than men

15 Affects women between 20-40
Muscle weakness Trembling hands Rapid heartbeat Fatigue Weight loss Diarrhea or frequent bowel movements Irritability and anxiety Vision problems (irritated eyes or difficulty seeing) Menstrual irregularities Intolerance to heat and increased sweating Infertility

16 Hypothyroidism Too little thyroid hormone from an underactive thyroid gland body's metabolism is slowed Maybe a result of the pituitary gland not producing Thyroid homone Releasing hormone causing many physical and mental processes to become sluggish body consumes less oxygen and produces less body heat

17 Fatigue Mental depression Sluggishness Feeling cold Weight gain Dry skin and hair Constipation Menstrual irregularities

18 Thyroid Nodules small swelling or lump in the thyroid gland
nodules represent either a growth of thyroid tissue or a fluid-filled cyst most nodules are not cancerous some thyroid nodules may produce too much thyroid hormone or become too large, interfering with an individual's breathing or swallowing or may cause neck discomfort.
