Who is an endocrinologist?
An endocrinologist is a specialist doctor who treats imbalances of hormones or the endocrine system of the body. An endocrinologist is trained for almost two to three years in endocrinology after completing four years of medical schooling and three years of post-graduation in internal medicine.
Hormones are secreted by the endocrine glands of the body. Different hormones have different actions. Each hormone acts on a specific body part. They help in the growth and development of the body and regulate various bodily functions. Some hormones help in your growth and development, some help in regulating your blood pressure and temperature, and others help a woman to conceive or become pregnant.
Hormones play an indirect yet crucial role in your
Endocrinology is a branch of the medical field that deals with diseases related to hormones and the glands that secrete them (endocrine glands). The glands that secrete the hormones include:
- Pancreas: A gland located in your abdomen that makes insulin and glucagon.
- Thyroid: A butterfly-shaped gland in your neck that controls your metabolism, energy, and brain growth and development.
- Pituitary gland: A pea-sized gland located at the base of your brain that controls all the other hormones.
- Adrenal glands: A pair of glands, one on each side of the abdomen, located on the top of your kidneys. They exert control on your blood pressure, metabolism, stress response, and sex hormones.
- Parathyroid glands: Four small glands in your neck that control the level of calcium in your blood.
- Hypothalamus: A small gland located at the base of your brain that controls body temperature, hunger, and thirst.
- Ovaries: Reproductive glands (gonads) in females that contain eggs.
- Testes: Reproductive glands (gonads) in males that contain sperms.
- Pineal gland: A gland found near the center of the brain that may be linked to sleep patterns.
- Thymus: A gland in the upper part of your chest that helps in the development of the body’s immune system during the early stages of your life.
What diseases does an endocrinologist treat?
An endocrinologist treats diseases due to the imbalance of hormones in the body. The endocrine diseases may be either due to an increase or decrease in the production or secretion of hormones.
The most common diseases treated by an endocrinologist include:
Other diseases that an endocrinologist treats include:
- Polycystic ovarian disease (PCOD)
- Addison’s disease (deficiency of hormones of adrenal glands)
- Cushing’s syndrome (excessive production of the hormone cortisol which leads to weight gain and puffy face)
- Gigantism (a child whose bones and body parts grow abnormally fast)
- Dwarfism (abnormally short stature)
- Certain cancers of the endocrine glands
Why would you go to an endocrinologist?
You would be referred to an endocrinologist by your family doctor, or you can visit him/her on your own if
- You are a diabetic and
- You have abnormalities found in your thyroid blood tests
- You have developed brittle bones (osteoporosis)
- You are a female with irregular periods
- If you have a short stature that does not match your age
- Usually mothers approach the endocrinologist for this problem in their children during puberty.
- You suffer from excessive hair loss (alopecia)
- You are a male whose breast size is increasing (gynecomastia)
What tests are used by an endocrinologist?
Your endocrinologist will ask you a lot of questions that may seem irrelevant to you, but these are necessary because an endocrine disease affects the whole body.
Tests usually asked for by an endocrinologist include:
- Blood sugar level
- Complete blood count
- Kidney function test
- Liver function test
- Thyroid function tests
- Thyroid antibodies test including thyroid peroxidase (TPO) antibodies
- Cortisol level
- Adrenocorticotropic hormone (ACTH) level
- Prolactin level
- Testosterone level
- The doctor may order a urine sugar test if you have diabetes.
- Your endocrinologist may order the following radiological tests to ascertain his diagnosis:
- Ultrasonography (USG) of pelvis: To check abnormalities in your pancreas and reproductive organs.
- Doppler scan of thyroid
- X-ray of bones to check for osteoporosis
- Computed tomography scan
- Magnetic resonance imaging
- Positron emission tomography scan if the doctor suspects cancer

Diabetes (Type 1 and Type 2)Diabetes is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Hashimoto's ThyroiditisHashimoto's thyroiditis or chronic lymphocytic thyroiditis, is an autoimmune disorder causing inflammation of the thyroid gland. Hashimoto's thyroiditis is a type of hypothyroidism, and is the most common cause of hypothyroidism in the US.
Symptoms of Hashimoto's thyroiditis may include dry skin, fatigue, weight gain, feeling cold, excessive sleepiness, dry skin, dry coarse hair, difficulty swallowing, a lump in the front of the throat, muscle cramps, mood changes, vague aches and pains, problems concentrating, leg swelling, constipation, and depression.
There is no cure for Hashimoto’s thyroiditis. Diet changes, natural supplements, vitamins, or other natural products will not treat Hashimoto’s thyroiditis. Treatment for the autoimmune disorder is with thyroid hormone replacement therapy, which will be necessary for the rest of the person’s life.
Hormonal Methods of Birth ControlThere are several different hormonal methods of birth control. The hormones can be estrogen and/or progesterone. The hormones can be taken by mouth, implanted into body tissue, absorbed from a patch on the skin, injected under the skin, or placed in the vagina. Common types of hormonal birth control include: "The Pill" (oral contraceptives), injection (Depo-Provera, Lunelle), the patch (Ortho-Evra), and the vaginal ring (Nuvaring).
25 Hormone Imbalance Symptoms and SignsHormone imbalance including abnormal levels of estrogen, testosterone, cortisol, progesterone, and other hormones may lead to symptoms like weight gain, fatigue, and mood swings. Hormonal imbalance may be due to natural states, like menopause, or other conditions. See your doctor for suspected imbalances in hormonal systems.
Hormone TherapyEstrogen therapy, estrogen/progestin therapy, and hormone therapy are terms that refer to the administration of estrogen or estrogen/progestin for the purpose of suppressing hot flashes. Side effects of hormone therapy include headaches, nausea, breast pain, blood clots, breast cancer, heart disease, abnormal vaginal bleeding, stroke, and uterine cancer.
Hyperthyroidism is an excess of thyroid hormone due to an overactive thyroid gland. Symptoms can include increased heart rate, weight loss, heart palpitations, frequent bowel movements, depression, fatigue, fine or brittle hair, sleep problems, thinning skin, and irregular vaginal bleeding.
Graves' disease is the most common cause of hyperthyroidism. Many other health problems or taking excess thyroid hormone medication can cause an overactive thyroid gland. Treatment for the condition is with medication, radioactive iodine, thyroid surgery (rarely), or reducing the dose of thyroid hormone. No diet has been shown to treat hyperthyroidism or its symptoms and signs.
Hyperthyroidism SlidesWhat is hyperthyroidism? Hyperthyroidism occurs when an overactive thyroid gland produces an excessive amount of thyroid hormones. Learn hyperthyroidism causes, symptoms, and treatment.
Hypothyroidism is any state in which thyroid hormone production is below normal. Normally, the rate of thyroid hormone production is controlled by the brain by the pituitary gland. Hypothyroidism is a very common condition and the symptoms of hypothyroidism are often subtle, but may include, constipation, memory loss, hair loss, and depression. There are a variety of causes of hypothyroidism, and treatment depends on the cause.
Hypothyroidism During Pregnancy
Hypothyroidism during pregnancy can be treated with synthetic thyroid hormones to maintain the proper thyroid hormone balance. Hypothyroidism symptoms include fatigue, weight gain, lethargy, and constipation. Treatment of hypothyroidism in pregnant women is important, because inadequate levels of thyroid hormones may affect the fetus, and child during growth and development.
Thyroid Disorders Symptoms and SignsThyroid diseases and disorders are caused because the body either makes too much or too little thyroid hormones, which are necessary for vital functions of the body.
Thyroid disease and disorder symptoms and signs depend on the type of the thyroid problem. Examples include heat or cold intolerance, sweating, weight loss or gain, palpitations, fatigue, dry skin, constipation, brittle hair, joint aches and pains, heart palpitations, edema, feeling bloated, puffiness in the face, reduced menstrual flow, changes in the frequency of bowel movements and habits, high cholesterol, hoarseness, brittle hair, difficulty swallowing, shortness of breath, a visible lump or swelling in the neck, tremors, memory problems, depression, nervousness, agitation, irritability, or poor concentration.
Thyroid problems are more common in women.
Thyroid DisordersThere are several types of thyroid disorders including hypothyroidism, hyperthyroidism, goiters, thyroid nodules, and thyroid cancer. Symptoms vary by condition. Diagnosis is made with blood tests, scans, ultrasound, or biopsy. Treatments depend on the disorder and can include medication or surgery.
Thyroid NodulesThyroid nodules are the most common endocrine problem in the United States. The term thyroid nodule refers to any abnormal growth that forms a lump in the thyroid gland. The vast majority of thyroid nodules are benign.
