What is an endocrinologist?
An endocrinologist is a physician with training in allopathic medicine (MD) or osteopathic medicine (DO) who specializes in treating, diagnosing, and managing diseases and health conditions linked to hormones, the endocrine system glands, and hormonal imbalances. Because many of the disorders they treat are chronic and do not require surgery, you will likely see an endocrinologist in an outpatient environment. Some endocrinologists also conduct consultations in hospital settings. Endocrinology, a branch of science that deals with the endocrine system, is a subspecialty of internal medicine.
The education of an endocrinologist includes:
- Four years of medical school;
- Two or three years of residency in pediatrics or internal medicine;
- A two to three-year fellowship in metabolism, endocrinology, or diabetes;
- The American Board of Internal Medicine's examination for internal medicine board certification;
- An additional certification examination for endocrinology, diabetes, and metabolism
Different subspecialties within endocrinology
There are numerous subspecialties within endocrinology. Some of them are:
- Endocrinology nuclear medicine focuses on applying nuclear medicine and its related fields to treat specific endocrine problems, such as thyroid disorders.
- Endocrine oncology focuses on preventing, identifying, and treating different cancers that affect the body's endocrine system. These include adrenocortical carcinoma, pituitary, neuroendocrine, parathyroid, and adrenal tumors. Endocrine oncologists are endocrinologists who focus on endocrine cancer.
- Pediatric endocrinology focuses on treating endocrine conditions that affect kids. While some endocrine disorders only affect children, most endocrine disorders affect adults and children.
- Neuroendocrinology focuses on the interaction between the endocrine and nervous systems. This field analyzes how the brain manages bodily hormonal activity.
- Reproductive endocrinology focuses on the effects of the endocrine system on the reproductive system. Multiple hormones regulate the body's sexual and reproductive processes. Reproductive endocrinologists are also called fertility specialists. Hence, sexual and reproductive health are primary areas of specialization for these endocrinologists.
- Gender affirmation focuses on helping gender-dysphoric or gender-incongruent people to develop the physical characteristics of their affirmed gender.
The five most common endocrine disorders
An endocrine system is a group of hormone-secreting glands. These hormones are secreted into the blood, which then travel to other glands to regulate vital functions of the body. Various factors, such as an adrenal or pituitary gland tumor, hormonal imbalances, and autoimmune conditions, cause endocrine disorders, and they are generally challenging to diagnose as each disease shows several symptoms, and many symptoms overlap with those of other conditions. Doctors diagnose endocrine disorders through urine, blood, hormones, genetic tests, and MRI scans.
The five most common endocrine disorders are described below:
The thyroid is a small butterfly-shaped organ at the front of the neck, surrounding the trachea. It releases thyroxine (T4) and triiodothyronine (T3) hormones, collectively known as thyroid hormones. Thyroid hormones aid in the regulation of energy usage throughout the body. Oversecretion of this hormone leads to hyperthyroidism, and under-secretion leads to hypothyroidism.
Hyperthyroidism, i.e., excess hormone secretion, leads to overdrive, showing symptoms such as irregular heartbeats, tiredness, frequent bowel movements, increased appetite, weight loss, goiter, irritability, nervousness, and sleep problems.
Hypothyroidism, i.e., deficiency of thyroid hormone, slows down bodily function, leading to symptoms of slow heartbeat, dry skin, muscle cramps, constipation, weight gain, tingling in hands, facial swelling, slow speech, tiredness, and sensitivity to cold.
Insulin is secreted by the pancreas, which regulates the blood sugar level. The body's inefficiency in producing or using insulin sufficiently leads to increased blood sugar levels, and this condition is known as diabetes. Diabetes can be categorized into two types, namely, Type 1 and Type 2. Common symptoms of this condition include increased hunger, thirst, urination, decreased vision, tiredness, tingling in hands and feet, and soreness.
- Polycystic ovary syndrome (PCOS)
PCOS is an endocrine condition leading to enlarged ovaries with small cysts on the margins. It is caused due to an imbalance in reproductive hormones. Common symptoms of PCOS include acne, hair fall, irregular menstrual cycle, excessive hair, weight gain, and skin darkening.
The pituitary gland releases the growth hormone responsible for regulating body height, muscle growth, and bone length. Acromegaly is a condition in which excess growth hormone is released, leading to unusual growth of bones, tissues, and organs. Common symptoms include swelling in feet and hands, bone changes such as protruding jaw and facial changes, dry skin, body odor, and deep voice.
The primary stress hormone, called cortisol, is secreted by the adrenal cortex. Cortisol aids blood pressure maintenance, metabolic regulation, and the body's reaction to stress. Cushing's syndrome, or hypercortisolism, is the condition in which excess cortisol is released. Common symptoms include muscle weakness, weight gain, excessive hair growth, a fatty lump between shoulders, reduced fertility and sex drive, tiredness, blurry vision, and easy bruising.
What is endocrine cancer?
An endocrine tumor develops when abnormal cells in an endocrine gland or organ grow out of control. Endocrine tumors are classified into two broad varieties: functioning and nonfunctioning tumors.
Functioning tumors are those that produce and release hormones. When cancer develops from a hormone-producing cell, the cells that make the tumor grow and release excessive amounts of the hormones produced by the initial cell, which can result in various symptoms and issues in the body depending on which hormone is involved. Nonfunctioning tumors are those that do not produce or release hormones.
Both functioning and nonfunctioning tumors can grow into huge masses that press against neighboring tissues and organs, affecting their ability to function normally.
What are the types of endocrine cancer?
Any endocrine gland or tissue in the body might develop cancer. The following are a few types:
- Pituitary tumors: The pituitary gland, a pea-sized structure found just below the brain, produces various hormones that balance the activity of other endocrine glands, such as the adrenal and thyroid glands and the gonads (the ovaries and testicles). The pituitary gland regulates several bodily functions, including blood pressure, growth, metabolism, as well as sperm and egg production. Pituitary gland tumors are usually benign, but a tiny percentage of them could grow into cancers.
- Adrenal cancers: The two adrenal glands, positioned directly above the kidneys, create hormones that regulate various vital biological processes, including metabolism, stress response, inflammation, blood pressure, and sexual development. Aldosterone, cortisol, and adrenaline (sometimes called epinephrine) are examples of adrenal hormones. Adrenocortical carcinoma and pheochromocytoma are two kinds of cancer that can develop in the adrenal gland, although the latter is usually benign.
- Pancreatic cancers: Specialized neuroendocrine cells in the pancreas produce and secrete hormones such as glucagon and insulin to help with blood sugar regulation. Neuroendocrine cells combine the features of nerve cells and hormone-producing endocrine cells. Pancreatic neuroendocrine tumors (pNETs) or islet cell tumors are cancerous tumors that grow from these neuroendocrine cells.
When should you visit an endocrinologist?
Endocrine conditions can develop at any age, regardless of gender. As you age, your hormone levels might decrease, or their production may slow down. These changes can trigger various symptoms like muscle loss, irregular periods, night sweats, sleep problems, or slower metabolism.
Tell your primary care provider (PCP) about any unusual changes in your body right away. Your PCP can check your glucose, thyroid, testosterone, estrogen, and other hormone levels through specific tests. If your results show abnormal levels, your PCP will connect you with an endocrinologist.
Watch for these warning signs that last a long time and affect your daily activities; they signal that you may need to consult an endocrinologist:
- Unclear vision
- Pain in bones or joints
- Mental fog
- Skin dryness
- Excessive thirst
- Need to urinate often
- Losing hair
- Hot flashes
- Trouble sleeping
- Unusual hair growth
- Eating more than usual
- Heart rhythm changes
- Menstrual cycle irregularities
- Shifts in mood
- Weak muscles
- Unexpected weight changes
What to expect during your initial visit to an endocrinologist?
Usually, your primary care physician (PCP) will refer you to an endocrinologist near you for suspected hormone problems. During your initial visit, the endocrinologist will inquire about your symptoms, lifestyle choices, family history of hormone-related issues, other medical conditions, and the use of medications. They will review your medical records and cross-check with the doctor who referred you.
An endocrinologist will also conduct a physical exam during which they will check your blood pressure, heart rate, and pulse. They will examine your mouth, teeth, skin, and hair because some hormone-related conditions can affect these areas. Additionally, they may perform a biopsy, order an ultrasound or imaging tests like computed tomography (CT) and magnetic resonance imaging (MRI) scans, and order blood work or urinalysis.
After diagnosing, the endocrinologist will develop a treatment plan with you and your referring physician. Some patients continue to visit an endocrinologist to help them manage long-term hormone-related conditions. Others may only require a short visit with an endocrinologist, followed by follow-up treatment and symptom management from primary care physicians.
It would be best to keep visiting your family or primary care physician to address any additional issues.
What tests do endocrinologists order?
As you identify concerning symptoms, your endocrinologist will perform various tests to determine your specific disorder and develop the right treatment plan. They may perform one or more of the following common testing procedures:
- Ultrasound: Uses sound waves to detect abnormal masses or fluids in soft tissues like the thyroid, lymph nodes, and parathyroid glands.
- CT scan: Creates detailed cross-sectional images of your chest, neck, and abdomen using X-rays, allowing an inside look without invasive procedures.
- Fine needle aspiration: Inserts a needle to extract cells from thyroid nodules for further examination by a specialist.
- Sestamibi scan: Injects radioactive dye that highlights any enlarged parathyroid glands.
- MRI: Generates cross-sectional images of soft tissues, parathyroid glands, adrenal glands, and liver using magnetic fields.
- PET scan: Identifies increased glucose metabolism associated with various cancers.
- Venous sampling: Inserts a catheter into a vein to extract blood and check hormone levels in specific areas of the body.

Statistics of endocrine disorders in Detroit, Michigan
Diabetes is one of the most common endocrine disorders in the United States. The Centers for Disease Control and Prevention (CDC) reports that more than 37 million people in the US have diabetes, which has life-threatening complications. According to the American Diabetes Association, 59,201 people in Michigan are diagnosed with diabetes every year. Approximately 964,964 people, which amounts to 12.2% of adults, have diabetes. Additionally, around 239,000 people in Michigan have diabetes but are unaware of it, putting their health in danger.
Additionally, 2,701,000 people, or 34.7% of adults, have prediabetes. Prediabetes is a condition wherein blood glucose levels are higher than the optimal range but not yet high enough to be diagnosed as diabetes. Diabetes puts a toll on budgets. Diabetes patients incur medical bills that are approximately 2.3 times higher than individuals who do not have diabetes.
After diabetes, thyroid disorders are the second most common endocrine disorder in the United States. According to an article published on Healthgrades, about 20 million Americans have some thyroid disorder. The article also stated that PCOS is common among women of reproductive age and affects around 5 million women in the US.
The increasing consumption of unhealthy and packaged foods increases the incidence of hormonal disorders. People must change their lifestyle and eating habits to maintain a physically healthy and mentally stable life.
