Endocrine Disorders
Your key endocrine glands include:
Thyroid glandPituitary glandPineal glandPancreasOvariesTestesParathyroidHypothalamusAdrenals
Some of the most common endocrine disorders are number of thyroid-related conditions, including:
Hypothyroidism Hyperthyroidism Hashimoto’s thyroiditis Graves’ disease Thyroid cancer Goiter Thyroiditis Thyroid nodules
Some other common endocrine disorders include:
Adrenal disorders Diabetes Osteoporosis Pituitary disorders Polycystic ovary syndrome
Causes of Endocrine Disorders
Endocrine disorders have a number of causes, including:
Dysfunction of a gland, due to genetics, injury, or infection Benign or cancerous gland tumors or growths, interfering with gland function Autoimmune disease, when the immune system attacks the gland A problem with communication between endocrine glands, causing over or under stimulation A genetic disorder, such as multiple endocrine neoplasia (MEN) or congenital hypothyroidism
How Are Endocrine Disorders Diagnosed?
Endocrine disorders are commonly diagnosed based on symptoms, medical history, blood tests, and in some cases, imaging tests, and biopsies.
Typically, endocrine disorders cause a deficiency or excess of hormones, so testing for the presence, excess, or deficiency of hormones and the body’s ability to produce them when provoked is a key step in the diagnosis.
For example:
Testing for adrenal disorders can include measurement of levels of the key adrenal hormone cortisol, as well as challenge tests that measure the body’s ability to produce cortisol when stimulated. Diabetes testing looks at glucose levels at a moment in time, over a longer period (such as with the hemoglobin A1C test), and may also look at the body’s ability to respond to glucose, such as in the glucose challenge test. Polycystic ovary syndrome diagnosis involves a combination of history taking to learn about your menstrual cycle and symptoms, physical exam findings, blood tests to evaluate estrogen and testosterone levels, and potentially, imaging tests to detect ovarian cysts.
Endocrine disorders of the thyroid gland are typically diagnosed by clinical examination and blood tests, and in some cases, imaging tests and thyroid biopsy.
What Is Autoimmune Disease?
The immune system is complex, and its job is to protect us from diseases and defend against infections, including bacteria, viruses, and pathogens.
With an autoimmune disease, the immune system mistakenly attacks healthy cells, organs, tissues, or glands in the body as if they were infections or pathogens. Autoimmune disease is sometimes referred to as “friendly fire” by the immune system against our own body.
Some of the better-known autoimmune diseases include Hashimoto’s thyroiditis, Graves’ disease, multiple sclerosis, rheumatoid arthritis, lupus, and alopecia.
Causes of Autoimmune Diseases
Often, there isn’t a clear cause of most autoimmune diseases, and they can develop sporadically, without a tumor or family history of the condition. But certain factors can increase the risk of developing an autoimmune disease—genetics, toxic exposures, stress, pregnancy, and nutritional deficiencies.
What Are the Symptoms of Autoimmune Disease?
Autoimmune diseases can be complicated to diagnose, because in some cases, early symptoms may be vague and non-specific, such as fatigue, muscle aches and pain, and brain fog. Sometimes autoimmune conditions cause inflammation, and that can cause swelling or discomfort.
Other symptoms really depend on the target of the autoimmune disease.
With autoimmune thyroid disease, symptoms such as fatigue and weight changes reflect changes in thyroid function. Multiple sclerosis, which attacks the communication between nerve cells, can result in difficulties with coordination and walking. Rheumatoid arthritis, which attacks the joints, can cause pain, swelling, and impaired joint function.
How Is Autoimmune Disease Diagnosed and Treated?
Autoimmune disease diagnosis and treatment depends on the disease. The diagnosis process typically includes a clinical examination, family history, and blood tests as a starting point.
Blood tests may measure key functions of organs that are targeted, but the key measures typically are evaluations of antibody levels, and markers and measures of inflammation and inflammatory responses in the body, such as an antinuclear antibody test (ANA).
In some cases, imaging tests may be performed, such as X-rays to assess joint damage in rheumatoid arthritis, or an MRI to look for brain lesions in multiple sclerosis. Less often, a biopsy may be needed to differentiate benign from cancerous lesions or to help detect immune markers in organs or glands that are not evident from blood tests.
Treatment
Treatment of autoimmune diseases frequently aims to reduce inflammation, relieve symptoms, and rebalance affected hormones. In the cases of debilitating autoimmune diseases, modulation of the immune system to slow the rate of permanent damage to organs and tissues may be an important part of treatment.
