What is the endocrine system?

The endocrine system is a complex group of glands. Glands are organs that make hormones. These are substances that help to control activities in your body. Different types of hormones control reproduction, metabolism (food burning and waste elimination), growth and development. Hormones also control the way you respond to your surroundings, and they help to provide the proper amount of energy and nutrition your body needs to function. The glands that make up the endocrine system include the thyroid, parathyroid, pancreas, ovaries, testes, adrenal, pituitary and hypothalamus.		  
     
  What is an endocrinologist?

An endocrinologist is a specially trained doctor. Endocrinologists diagnose diseases that affect your glands and hormones. They know how to treat conditions that are often complex and involve many systems within your body.		  
     
  What do endocrinologists do?
Endocrinologists are trained to diagnose and treat hormone disturbances by helping to restore the normal balance of hormones in your system. They take care of many conditions including:		  
 
  • Diabetes
    Risk Assessment
    Screening & Prevention
    Drugs & Insulins
    Insulin Pumps & Continuous Glucose Monitoring System (CGMS)
  • Obesity
  • Lipid (Cholesterol) Disorders
  • Metabolic Syndrome
  • Hormonal Causes of Weight Loss & Weight Gain
  • Thyroid Disorders
  • Polycystic Ovary Syndrome (PCOS)
  • Hormonal Causes of Irregular Periods
  • Excessive Hair Growth & Hair Loss in Females
  • Osteoporosis (Brittle Bones)
  • Vitamin D Deficiency
  • Calcium & Phosphorous Imbalances
  • Pituitary Gland Disorders
  • Parathyroid Gland Disorders
  • Adrenal Gland Disorders
  
  What are the most common endocrine diseases and disorders?  
 
Diabetes

Diabetes is a condition in which a person has a high blood sugar (glucose) level, either because the body doesn't produce enough insulin, or because body cells don't properly respond to the insulin that is produced. Insulin is a hormone produced by the pancreas (an endocrine gland located below and behind the stomach). Insulin enables body cells to absorb glucose, to turn into energy. If the body cells do not absorb the glucose, the glucose accumulates in the blood (hyperglycemia), leading to vascular, nerve, and other complications.		  
     
 




















Recent studies have found that controlling blood sugar helps prevent serious problems that can be caused by diabetes. These can include problems with the eyes, kidneys and nerves, which can lead to blindness, dialysis, or amputation. Endocrinologists treat diabetes with diet and medications, including insulin. They also work closely with patients to control blood sugar and monitor them to prevent health problems.		  
   
     
  Thyroid

The thyroid gland is a butterfly-shaped endocrine gland that is normally located in the lower front of the neck. The thyroid gland produces thyroid hormone, which is secreted into the blood and then carried to every tissue in the body. Thyroid hormone is essential to help each cell in each tissue and organ to work right. For example, thyroid hormone helps the body use energy, stay warm, and keep the brain, heart, muscles, and other organs working as they should.		  
 







Patients with thyroid conditions often have problems with their energy levels. They may also have problems with muscle strength, emotions, weight control, and tolerating heat or cold. Endocrinologists treat patients with too much or too little thyroid hormone (conditions respectively caused by either an overactive or underactive thyroid). They help patients reach a hormone balance by replacing or blocking thyroid hormone. Endocrinologists also receive special training to manage patients with thyroid nodules or thyroid cancer, and enlarged thyroid glands.		  
  Bone

Endocrinologists can diagnose and treat osteoporosis (brittle bones). Osteoporosis is a disease in which bones become fragile and more likely to break. If not prevented or if left untreated, osteoporosis can progress painlessly until a bone breaks. These broken bones, also known as fractures, occur typically in the hip, spine, and wrist.		  
 








Certain hormones act to protect bone tissue. When hormone levels are abnormal, bones can lose calcium and weaken. Menopause, in women, and loss of testicle function, in men, and aging may put you at risk for bone fractures. Endocrinologists treat other disorders that can affect bones, such as too much parathyroid hormone and long term use of steroids like prednisone.		  
   
     
  Reproduction/Infertility

Endocrinologists diagnose and treat hormone imbalances that can cause infertility and reproductive problems. They work with patients who need hormone replacement. Problems treated by endocrinologists specializing in reproductive endocrinology include menopause symptoms, irregular periods, polycystic ovary syndrome (PCOS), premenstrual syndrome, and impotence.		  
   
     
  Pituitary Gland

The pituitary is often called the master gland of the body because it controls other glands. The pituitary makes several important hormones. Over - or under - production of pituitary hormones can cause a hormone imbalance that can lead to infertility, menstrual disorders, growth disorders (acromegaly or short stature) and too much cortisol production (Cushing's syndrome). Endocrinologists control these conditions with medications and refer patients who need surgery.		  
     
     
  The Adrenal Glands & Hypertension

The adrenal glands (also known as suprarenal glands) are the triangular-shaped endocrine glands that sit on top of the kidneys. They are chiefly responsible for releasing hormones through the synthesis of cortisol, aldosterone, androgens, and adrenaline (epinephrine).
Hypertension is high blood pressure, and it is a risk factor for heart disease, stroke, kidney and eye disease. Up to 10% of people have hypertension because of too much aldosterone, a hormone produced in the adrenal glands. About half of these cases are caused by growths that can be removed with surgery. Conditions such as the metabolic syndrome or a rare adrenal growth called a pheochromocytoma also may cause a hormone imbalance that leads to hypertension. These conditions also can be treated successfully.		  
     
  Lipid Disorders

Patients with lipid disorders have trouble maintaining normal levels of body fats. Lipid disorders include - high levels of total cholesterol, high levels of low-density lipoprotein cholesterol LDL (known as "the bad cholesterol"), high levels of triglycerides, and low levels of high-density lipoprotein HDL (known as "the good cholesterol"). Lipid disorders are linked to heart (coronary) disease, strokes, and peripheral vascular disease (problems with circulation in the legs).
Endocrinologists are trained to detect factors that may be related to lipid disorders, such as hypothyroidism (a hormone imbalance caused by thyroid conditions), drug use (such as steroids), genetic or metabolic conditions. Lipid disorders can be found in several conditions that require special management, including the metabolic syndrome, polycystic ovary syndrome (PCOS), and obesity. Special diets, exercise, and medications may be prescribed to manage patients with lipid disorders. 		  
 
 
  
  Obesity and Overweight

Endocrinologists treat patients who are overweight or obese, sometimes because of metabolic and hormonal problems. When someone is obese they have too much body fat. Thyroid, adrenal, ovarian, and pituitary disorders can cause obesity. Endocrinologists also identify factors linked to obesity, such as insulin resistance and some rare genetic problems.

  Type 1

Type 1 diabetes is usually diagnosed in children and young adults, and was previously known as juvenile diabetes. In type 1 diabetes, the body does not produce insulin. Insulin is a hormone that is needed to convert sugar, starches and other food into energy needed for daily life. Only 5-10% of people with diabetes have this form of the disease. With the help of insulin therapy and other treatments, even young children with type 1 diabetes can learn to manage their condition and live long, healthy, happy lives.
  
  Type 2

Type 2 diabetes is the most common form of diabetes. Millions of people have been diagnosed with type 2 diabetes, and many more are unaware they are at high risk. Some groups have a higher risk for developing type 2 diabetes than others.

In type 2 diabetes, either the body does not produce enough insulin or the cells ignore the insulin. Insulin is necessary for the body to be able to use glucose for energy. When you eat food, the body breaks down all of the sugars and starches into glucose, which is the basic fuel for the cells in the body. Insulin takes the sugar from the blood into the cells. When glucose builds up in the blood instead of going into cells, it can lead to diabetes complications.
  
  Gestational Diabetes

Pregnant women who have never had diabetes before but who have high blood sugar (glucose) levels during pregnancy are said to have gestational diabetes. Gestational diabetes affects about 4% of all pregnant women.
We don't know what causes gestational diabetes, but we have some clues. The placenta supports the baby as it grows. Hormones from the placenta help the baby develop. But these hormones also block the action of the mother's insulin in her body. This problem is called insulin resistance. Insulin resistance makes it hard for the mother's body to use insulin. She may need up to three times as much insulin.
Gestational diabetes starts when your body is not able to make and use all the insulin it needs for pregnancy. Without enough insulin, glucose cannot leave the blood and be changed to energy. Glucose builds up in the blood to high levels. This is called hyperglycemia.
  
  How gestational diabetes can affect your baby
  
 
  • Gestational diabetes affects the mother in late pregnancy, after the baby's body has been formed, but while the baby is busy growing. Because of this, gestational diabetes does not cause the kinds of birth defects sometimes seen in babies whose mothers had diabetes before pregnancy.
  • However, untreated or poorly controlled gestational diabetes can hurt your baby. When you have gestational diabetes, your pancreas works overtime to produce insulin, but the insulin does not lower your blood glucose levels. Although insulin does not cross the placenta, glucose and other nutrients do. So extra blood glucose goes through the placenta, giving the baby high blood glucose levels. This causes the baby's pancreas to make extra insulin to get rid of the blood glucose. Since the baby is getting more energy than it needs to grow and develop, the extra energy is stored as fat.
  • This can lead to macrosomia, or a "fat" baby. Babies with macrosomia face health problems of their own, including damage to their shoulders during birth. Because of the extra insulin made by the baby's pancreas, newborns may have very low blood glucose levels at birth and are also at higher risk for breathing problems. Babies with excess insulin become children who are at risk for obesity and adults who are at risk for type 2 diabetes.
  
  Symptoms
  
  1 - Type 1 Diabetes
People with type 1 diabetes may have noticeable early symptoms that often come on suddenly. Symptoms of type 1 diabetes may include:		  
 
  • Increased thirst
  • Increased urination
  • Constant hunger
  • Weight loss
  • Blurred vision
  • Fatigue, or a feeling of being tired
  
  2 - Type 2 Diabetes  
  Type 2 diabetes may occur without any symptoms, or symptoms may develop gradually. Type 2 diabetes symptoms may include:  
 
  • Frequent yeast infections
  • Very slow healing of wounds or sores
  • Nausea
  • Fatigue, or a feeling of being tired
  • Increased urination
  • Increased thirst
  • Weight loss
  • Blurred vision

If you have these symptoms of diabetes, please see your doctor for testing.

  
     
  Prevention
  
  Here are 7 Tips for Preventing Diabetes:
  
 
  1. Exercise is extremely important for preventing diabetes.  You need at least ½ hour of exercise per day. That means vigorous walking to get your heart rate up or any other type of exercise that helps you to work up a sweat. One hour a day is even better. New clinical trials showed that when participants walked vigorously for 30 minutes a day 5 days per week and also lost weight in the amount of 5-7% of their total body weight, they cut their risk of developing diabetes by 50%.
    Not only will lots of exercise help in preventing diabetes, it also enhances your immune system by getting your lymph system moving, it builds muscle and bones, improves heart and lung efficiency, reduces stress, burns fat, raises your metabolism and generally keeps your body young.
    Studies have revealed that exercise also lowers blood sugar and keeps it down for several hours after the exercise which also contributes to preventing diabetes.
  2. Lose weight: Weight loss is also extremely important in preventing diabetes.  About 80% of diabetics are overweight and excess weight has been shown to contribute to the development of diabetes. In fact just losing weight and exercising can often completely control all symptoms of diabetes.
  3. Do not eat trans fats (hydrogenated vegetable oils) of any kind. They have been shown to contribute to heart disease and may also contribute to diabetes type 2.
  4. Another important action in preventing diabetes is to avoid eating foods made with sugar, bleached (white) flour and other refined carbohydrates such as white rice and dry cereals in order to help in preventing diabetes. Processed and fried foods are particularly unhealthy and the fats and carbohydrates found in them undermine your health.  Stay away from high glycemic index foods.
  5. Eat lots of fiber, which is found in raw fruits and vegetables, beans, whole grains and oatmeal. Fiber will go a long way in preventing diabetes because it helps to buffer high amounts of sugar or carbohydrates in your diet, keeping your blood sugar even rather than having it gyrate wildly up and down.
  6. Don’t smoke. Smoking is not only associated with the development of diabetes but it also contributes to heart disease and causes lung cancer.
  7. Get a friend, relative or group of people to help you in preventing diabetes.  They can support you in sticking with your healthy new lifestyle.
  
  Tips
  
  Diabetes Diet and Weight Loss Tips  
 
  • Water consumption is very important in any diabetes diet.  Be sure to drink at least 6 glasses of water every day.
  • Exercise five (ideally 7) days per week at least ½ hour.
  • In many studies, it has been shown that for weight loss and the diabetes diet, you should be sure to get lots of fiber every day from foods such as oatmeal and oat bran, raw and cooked vegetables, ground flax seed, apples and supplements such as psyllium. 
  • High fiber foods help reduce your appetite while helping to control high blood sugar levels.
  • Go on a diabetes diet that avoids the empty calories found in sugar,  refined carbohydrates and unhealthy fats.
  • Give up candy and other sweets permanently; choose low glycemic index fruit instead (like apples or berries).  You'll find with this diabetes diet that you don't crave food or sweets as much as you did before.
  • Relaxation techniques will also help with your overall well-being. Use a relaxation tape every day or meditate.
