Your adrenal glands are just above your kidneys. The outside layer of these glands makes hormones that help your body respond to stress and regulate your blood pressure and water and salt balance. Addison disease happens if the adrenal glands don't make enough of these hormones.

A problem with your immune system usually causes Addison disease. The immune system mistakenly attacks your own tissues, damaging your adrenal glands. Other causes include infections and cancer.

Symptoms include:

• Weight loss
• Muscle weakness
• Fatigue that gets worse over time
• Low blood pressure
• Patchy or dark skin

Lab tests can confirm that you have Addison disease. If you don't treat it, it can be fatal. You will need to take hormone pills for the rest of your life. If you have Addison disease, you should carry an emergency ID. It should say that you have the disease, list your medicines and say how much you need in an emergency.

Your adrenal glands are two small organs that sit on top of each kidney. The adrenal glands make different types of hormones you need to stay alive and healthy. Hormones are chemicals that travel in your bloodstream and control how different parts of your body work.

The adrenal glands make the hormones cortisol, aldosterone, adrenaline, and noradrenaline. They also make hormones that your body uses to make sex hormones (estrogen and testosterone). All of these hormones do many important jobs, including:

• Turning food into energy and managing blood sugar levels
• Balancing salt and water
• Keeping blood pressure normal
• Responding to illness and stress (your "fight or flight" response)
• Timing when and how fast a child develops sexually
• Supporting pregnancy

When you have an adrenal gland disorder, your body makes too much or too little of one or more hormones. The symptoms depend on the type of problem you have and how much it affects the hormone levels in your body.

There are many types of adrenal gland disorders, including:

• Addison's Disease - a condition in which the adrenal glands don't make enough cortisol
• Cushing's Syndrome - a condition caused by too much cortisol in the body, often from taking steroid medicines for a long time
• Aldosterone-producing adenoma - a benign tumor (not cancer) that makes too much aldosterone and may cause serious high blood pressure
• Hereditary paraganglioma-pheochromocytoma - an inherited condition causing different types of tumors that make adrenaline and other hormones. Some tumors may become cancerous.
• Adrenal gland cancer - cancerous tumors, including adrenocortical carcinoma and neuroblastoma
• Congenital Adrenal Hyperplasia (CAH) - a group of inherited disorders in which the adrenal glands don't make enough cortisol. The most common type is 21-hydroxylase deficiency (also called CAH1). In the United States, newborn babies get a blood test to see if they have CAH. People born with CAH may not have symptoms until childhood or later in life.

The cause of adrenal gland disorders depends on the type of disorder you have. Causes can include:

• Medicines such as steroids
• A problem in another gland, such as the pituitary gland. The pituitary gland releases hormones that affect how the adrenal glands work.
• Changes in genes (mutations). These changes can cause the adrenal glands to make too much or too little of one or more hormones.
• Infections

In many cases the cause of the problem isn't clear.

Health care providers use different tests to check for adrenal disorders depending on your symptoms and health history. For example, you may have tests of your blood, urine (pee), or saliva (spit). These tests check your hormone levels. Your provider may order x-rays, CT scans, or MRI scans to look for tumors.

Different types of adrenal gland disorders have different treatments. They include medicines and surgery. Radiation therapy is sometimes a treatment for tumors. There are treatments to cure certain adrenal gland disorders. For other disorders, treatments can manage your symptoms.

Primary ovarian insufficiency (POI), also known as premature ovarian failure, happens when a woman's ovaries stop working normally before she is 40.

Many women naturally experience reduced fertility when they are about 40 years old. They may start getting irregular menstrual periods as they transition to menopause. For women with POI, irregular periods and reduced fertility start before the age of 40. Sometimes it can start as early as the teenage years.

POI is different from premature menopause. With premature menopause, your periods stop before age 40. You can no longer get pregnant. The cause can be natural or it can be a disease, surgery, chemotherapy, or radiation. With POI, some women still have occasional periods. They may even get pregnant. In most cases of POI, the cause is unknown.

In about 90% of cases, the exact cause of POI is unknown.

Research shows that POI is related to problems with the follicles. Follicles are small sacs in your ovaries. Your eggs grow and mature inside them. One type of follicle problem is that you run out of working follicles earlier than normal. Another is that the follicles are not working properly. In most cases, the cause of the follicle problem is unknown. But sometimes the cause may be:

• Genetic disorders such as Fragile X syndrome and Turner syndrome
• A low number of follicles
• Autoimmune diseases, including thyroiditis and Addison disease
• Chemotherapy or radiation therapy
• Metabolic disorders
• Toxins, such as cigarette smoke, chemicals, and pesticides

Certain factors can raise a woman's risk of POI:

• Family history. Women who have a mother or sister with POI are more likely to have it.
• Genes. Some changes to genes and genetic conditions put women at higher risk for POI. For example, women Fragile X syndrome or Turner syndrome are at higher risk.
• Certain diseases, such as autoimmune diseases and viral infections
• Cancer treatments, such as chemotherapy and radiation therapy
• Age. Younger women can get POI, but it becomes more common between the ages of 35-40.

The first sign of POI is usually irregular or missed periods. Later symptoms may be similar to those of natural menopause:

• Hot flashes
• Night sweats
• Irritability
• Poor concentration
• Decreased sex drive
• Pain during sex
• Vaginal dryness

For many women with POI, trouble getting pregnant or infertility is the reason they go to their health care provider.

Since POI causes you to have lower levels of certain hormones, you are at greater risk for other health conditions, including:

• Anxiety and depression. Hormonal changes caused by POI can contribute to anxiety or lead to depression.
• Dry eye syndrome and eye surface disease. Some women with POI have one of these eye conditions. Both can cause discomfort and may lead to blurred vision. If not treated, these conditions can cause permanent eye damage.
• Heart disease. Lower levels of estrogen can affect the muscles lining the arteries and can increase the buildup of cholesterol in the arteries. These factors increase your risk of atherosclerosis (hardening of the arteries).
• Infertility.
• Low thyroid function. This problem also is called hypothyroidism. The thyroid is a gland that makes hormones that control your body's metabolism and energy level. Low levels thyroid hormones can affect your metabolism and can cause very low energy, mental sluggishness, and other symptoms.
• Osteoporosis. The hormone estrogen helps keep bones strong. Without enough estrogen, women with POI often develop osteoporosis. It is a bone disease that causes weak, brittle bones that are more likely to break.

To diagnose POI, your health care provider may do:

• A medical history, including asking whether you have relatives with POI
• A pregnancy test, to make sure that you are not pregnant
• A physical exam, to look for signs of other disorders which could be causing your symptoms
• Blood tests, to check for certain hormone levels. You may also have a blood test to do a chromosome analysis. A chromosome is the part of a cell that contains genetic information.
• A pelvic ultrasound, to see whether or not the ovaries are enlarged or have multiple follicles

Currently, there is no proven treatment to restore normal function to a woman's ovaries. But there are treatments for some of the symptoms of POI. There are also ways to lower your health risks and treat the conditions that POI can cause:

• Hormone replacement therapy (HRT).HRT is the most common treatment. It gives your body the estrogen and other hormones that your ovaries are not making. HRT improves sexual health and decreases the risks for heart disease and osteoporosis. You usually take it until about age 50; that's about the age when menopause usually begins.
• Calcium and vitamin D supplements. Because women with POI are at higher risk for osteoporosis, you should take calcium and vitamin D every day.
• In vitro fertilization (IVF). If you have POI and you wish to become pregnant, you may consider trying IVF.
• Regular physical activity and a healthy body weight.Getting regular exercise and controlling your weight can lower your risk for osteoporosis and heart disease.
• Treatments for associated conditions. If you have a condition that is related to POI, it is important to treat that as well. Treatments may involve medicines and hormones.

Pigmentation means coloring. Skin pigmentation disorders affect the color of your skin. Your skin gets its color from a pigment called melanin. Special cells in the skin make melanin. When these cells become damaged or unhealthy, it affects melanin production. Some pigmentation disorders affect just patches of skin. Others affect your entire body.

If your body makes too much melanin, your skin gets darker. Pregnancy, Addison's disease, and sun exposure all can make your skin darker. If your body makes too little melanin, your skin gets lighter. Vitiligo is a condition that causes patches of light skin. Albinism is a genetic condition affecting a person's skin. A person with albinism may have no color, lighter than normal skin color, or patchy missing skin color. Infections, blisters and burns can also cause lighter skin.

Your immune system protects you from disease and infection by attacking germs that get into your body, such as viruses and bacteria. Your immune system can tell that the germs aren't part of you, so it destroys them. If you have an autoimmune disease, your immune system attacks the healthy cells of your organs and tissues by mistake.

There are more than 80 types of autoimmune diseases. They can affect almost any part of your body. For example, alopecia areata is an autoimmune disease of the skin that causes hair loss. Autoimmune hepatitis affects the liver. In type 1 diabetes, the immune system attacks the pancreas. And in rheumatoid arthritis, the immune system can attack many parts of the body, including the joints, lungs, and eyes.

No one is sure why autoimmune diseases happen. But you can't catch them from other people.

Autoimmune diseases do tend to run in families, which means that certain genes may make some people more likely to develop a problem. Viruses, certain chemicals, and other things in the environment may trigger an autoimmune disease if you already have the genes for it.

Millions of Americans of all ages have autoimmune diseases. Women develop many types of autoimmune diseases much more often than men. And if you have one autoimmune disease, you are more likely to get another.

The symptoms of an autoimmune disease depend on the part of your body that's affected. Many types of autoimmune diseases cause redness, swelling, heat, and pain, which are the signs and symptoms of inflammation. But other illnesses can cause the same symptoms.

The symptoms of autoimmune diseases can come and go. During a flare-up, your symptoms may get severe for a while. Later on, you may have a remission, which means that your symptoms get better or disappear for a period of time.

Doctors often have a hard time diagnosing autoimmune diseases. There's usually not a specific test to show whether you have a certain autoimmune disease. And the symptoms can be confusing. That's because many autoimmune diseases have similar symptoms. And some symptoms, such as muscle aches, are common in many other illnesses. So it can take a long time and some visits to different types of doctors to get a diagnosis.

To help your doctor find out if an autoimmune disease is causing your symptoms,:

• Learn about the health conditions in your family history. What health problems did your grandparents, aunts, uncles, and cousins have? Write down what you learn and share it with your doctor.
• Keep track of your symptoms, including how long they last and what makes them better or worse. Share your notes with your doctor.
• See a specialist who deals with the symptoms that bother you most. For example, if you have rash, see a dermatologist (skin doctor).

The treatment depends on the disease. In most cases, the goal of treatment is to suppress (slow down) your immune system, and ease swelling, redness, and pain from inflammation. Your doctor may give you corticosteroids or other medicines to help you feel better. For some diseases, you may need treatment for the rest of your life.

Your endocrine system includes eight major glands throughout your body. These glands make hormones. Hormones are chemical messengers. They travel through your bloodstream to tissues or organs. Hormones work slowly and affect body processes from head to toe. These include:

• Growth and development
• Metabolism - digestion, elimination, breathing, blood circulation and maintaining body temperature
• Sexual function
• Reproduction
• Mood

If your hormone levels are too high or too low, you may have a hormone disorder. Hormone diseases also occur if your body does not respond to hormones the way it is supposed to. Stress, infection and changes in your blood's fluid and electrolyte balance can also influence hormone levels.

In the United States, the most common endocrine disease is diabetes. There are many others. They are usually treated by controlling how much hormone your body makes. Hormone supplements can help if the problem is too little of a hormone.

You may have heard of anabolic steroids, which can have harmful effects. But there's another type of steroid - sometimes called a corticosteroid - that treats a variety of problems. These steroids are similar to hormones that your adrenal glands make to fight stress associated with illnesses and injuries. They reduce inflammation and affect the immune system.

You may need to take corticosteroids to treat:

• Arthritis
• Asthma
• Autoimmune diseases such as lupus and multiple sclerosis
• Skin conditions such as eczema and rashes
• Some kinds of cancer

Steroids are strong medicines, and they can have side effects, including weakened bones and cataracts. Because of this, you usually take them for as short a time as possible.
