What Is an Endocrinologist?

Endocrinologists are medical doctors who specialize in diagnosing and treating health conditions related to problems with the body’s hormones, hormonal glands, and related issues. They have specialized training in the endocrine system and can help diagnose, treat, and manage the illnesses that can arise when hormone imbalances or endocrine gland problems occur.

What Do Endocrinologists Do?

They cover a lot of ground, diagnosing and treating conditions that affect your:

  • Adrenals, glands that sit on top of your kidneys and help to control things like your blood pressuremetabolismstress response, and sex hormones
  • Bone metabolism, like osteoporosis
  • Cholesterol
  • Hypothalamus, the part of your brain that controls body temperature, hunger, and thirst
  • Pancreas, which makes insulin and other substances for digestion
  • Parathyroids, small glands in your neck that control the calcium in your blood
  • Pituitary, a pea-sized gland at the base of your brain that keeps your hormones balanced
  • Reproductive glands (gonads): ovaries in women, testes in men
  • Thyroid, a butterfly-shaped gland in your neck that controls your metabolism, energy, and brain growth and development

Reasons to See an Endocrinologist

Typically, you’ll see an endocrinologist in an outpatient setting after being referred by your primary care doctor. However, an endocrinologist could be called in to consult during an inpatient visit if there are concerns about an underlying hormone-related disorder.

Patients see endocrinologists for reasons ranging from diabetes management to problems with their thyroid, certain types of cancer, adrenal disorders, and more. Your doctor will likely refer you when there are concerns about: 

Difficulty Managing Diabetes with Standard Treatments

Individuals with diabetes typically see a primary care doctor regularly and may take medication to help keep their blood sugar levels stable. However, if standard treatment doesn’t get your blood sugar levels under control, your primary care doctor may refer you to an endocrinologist. An endocrinologist will look for additional strategies to help control your diabetes. 

Thyroid Disorder

Thyroid disorders can involve too much or too little of different types of hormones produced in the thyroid. You may be referred to an endocrinologist when a thyroid disorder is first diagnosed to review your condition and create a treatment plan. If there are no other complicating factors, you’ll complete follow-up care with your primary care doctor. 

However, sometimes you may need to get follow-up care from the endocrinologist. For instance, if you’re pregnant or looking to start a family and have a thyroid disorder, you may need to see an endocrinologist.

Other reasons to get follow-up care from an endocrinologist can include developing a goiter or enlarged thyroid gland, a thyroid nodule, or symptoms of a pituitary gland disorder. You may also need to go back to the endocrinologist if the symptoms that brought you there in the first place are not improving with treatment. 


Many factors contribute to osteoporosis, including age-related changes to hormone levels. When your primary care doctor suspects changes in hormone levels are contributing to osteoporosis, you may see an endocrinologist for evaluation and to develop a treatment plan.

Polycystic Ovary Syndrome

Polycystic ovary syndrome affects about 7% to 10% of women and can lead to infertilityacneunpredictable periodsunwanted facial hair, and other chronic conditions.

Low Testosterone

Low testosterone levels can result from several causes, including hormone disorders, medication side effects, and chronic diseases. An endocrinologist will use specialized knowledge to help diagnose, treat, and manage this condition. Sometimes you may need testosterone therapy, which is typically overseen by an endocrinologist.

Endocrine Gland Cancer

Cancer may happen in any of the endocrine glands, including the pancreas and the thyroid, pituitary, and adrenal glands. An endocrinologist will focus on managing and balancing hormone levels.

What to Expect at the Endocrinologist

You typically will see an endocrinologist in an outpatient setting, since many of the problems they treat are chronic conditions that don’t require surgery. Some endocrinologists also provide consultations in inpatient settings. 

Often, your primary care doctor will refer you to an endocrinologist for a suspected hormone problem. When you first visit, the endocrinologist will ask you a series of questions to learn more about your symptoms, health habits, other medical conditions, medications, and family history of hormone-related problems. They will consult with your referring doctor and review your medical records. 

Additionally, the endocrinologist will perform a physical exam, checking your pulse, heart rate, and blood pressure. They will assess your skin, hair, mouth, and teeth, as some hormone-related disorders can impact these areas. They may also order blood work or urinalysis, perform a biopsy, or order an ultrasound or imaging tests like computed tomography and magnetic resonance imaging scans. 

Once the endocrinologist has determined a diagnosis, they will work with you and your referring doctor on a treatment plan. Some people will continue to see the endocrinologist help them manage chronic hormone-related conditions.

You’ll continue to see your family or primary care doctor for other issues. Others may only need to see endocrinologists for a short amount of time, with further follow-up care and symptom management provided by primary care doctors.

**What Is⁣ an Endocrinologist?**


An endocrinologist is a medical specialist who diagnoses and treats⁤ conditions related to the endocrine system, the glands that produce and regulate hormones in the body.

**Scope of Practice:**

Endocrinologists deal with a wide range of hormone-related ​conditions, including:

*⁤ Thyroid disorders (e.g., ⁢hypothyroidism, hyperthyroidism)

* Pituitary ​gland disorders (e.g., Cushing’s syndrome, Addison’s disease)

* ‌Adrenal gland disorders (e.g., pheochromocytoma, Addison’s disease)

* Diabetes mellitus

* Thyroid cancer

* Pituitary tumors

* Polycystic ovary syndrome (PCOS)

* Growth hormone disorders

**Education ‌and Training:**

To ​become an endocrinologist, individuals must complete:

* Medical school (4 years)

*⁣ Internal medicine residency (3 years)

* Endocrinology​ fellowship (2-3 years)

**Diagnostic and Treatment Methods:**

Endocrinologists ‌use various diagnostic techniques ​to identify hormone imbalances, such‌ as:

* Blood tests to measure‌ hormone levels

* Imaging tests⁤ (e.g., ultrasound, MRI)

* Genetic testing

Treatment plans for endocrine disorders may include:

* Medication (e.g., hormone⁤ replacement therapy, anti-thyroid drugs)

* Surgery ⁣(e.g., thyroidectomy, pituitary tumor removal)

* ​Lifestyle modifications (e.g., exercise,⁢ diet)

**Additional Information:**

* Endocrinologists ‌often work in collaboration with other specialists, ⁢such as general physicians, surgeons, and nutritionists.

*⁢ They⁣ play a ‌crucial role in managing chronic conditions, such as ​diabetes and thyroid disorders, and in diagnosing⁢ and treating rare endocrine diseases.
