Articles Written by Robert M. Sargis MD, PhD

An Overview of the Hypothalamus
The hypothalamus helps maintain your internal balance by regulating many of the body’s key processes, such as heart rate and body temperature. It also controls some hormones of the pituitary gland to ensure that the body functions properly.
About the Endocrine System
The endocrine system helps your body properly function by communicating and coordinating vital processes via hormones. Hormones are produced and released by specific glands and are delivered through the bloodstream. Article is an endocrine overview.
What Is Low Testosterone?
Low testosterone, also called male hypogonadism, can be a very concerning medical condition. It can affect sex drive. Article covers low testosterone symptoms and causes.
How Your Thyroid Works
Thyroid hormone production and those factors which cause production to increase or decrease. Pictures help explain feedback between thyroid, pituitary, and hypothalamus. Article written by endocrinologist.
Thyroid Gland Overview
The thyroid, located in your neck, is a large endocrine gland that regulates your metabolism. It produces two main hormones to fulfill this role. The thyroid is associated with many distinct disorders, including hyperthyroidism and hypothyroidism.
How to Eat Well When You Have Graves’ Disease
There’s no such thing as a Graves’ disease diet, but eating certain foods can help ease Graves’ disease symptoms. Find out what foods you should be—and shouldn’t be—filling your plate with to live well with Graves’ disease.
An Overview of the Pituitary Gland
The pituitary gland is called the “master gland” because it controls functions of other endocrine glands. But it is largely regulated by the hypothalamus. It has two lobes that have different functions and secrete separate hormones.
Graves’ Disease Causes
Graves’ disease is an autoimmune disorder that may be caused by genetics. Learn about other Graves’ disease causes.
Graves’ Disease Symptoms
There are multiple symptoms of Graves’ disease—an autoimmune disorder that causes the thyroid gland to over-produce thyroid hormone, which is known as hyperthyroidism. In this article, you’ll read about the most common Graves’ disease symptoms.
An Overview of the Pancreas
The pancreas produces insulin and other hormones to help regulate blood sugar and salt. Learn more about the pancreas in this overview article.
An Overview of the Ovaries
The ovaries play a vital role in not only the reproductive system but also the endocrine system. Their main hormones—estrogen and progesterone—ensure proper female development and fertility. This article also summarizes ovarian diseases.
An Overview of the Adrenal Glands
The adrenal glands secrete adrenaline to help your body respond to stress, but they also regulate many vital processes in your body, such as metabolism.
An Overview of the Parathyroid
The parathyroid gland has a single responsibility in the endocrine system—to regulate calcium levels. To do this, it secretes parathyroid hormone. The parathyroid is located near your thyroid; however, their functions are not connected.
An Overview of the Testes
The testes are twin endocrine glands that release testosterone, a hormone necessary for the normal development of male physical characteristics, such as muscle mass and hair growth. This article overviews testes function in the endocrine system.
An Overview of the Thymus
The thymus gland is largest during childhood and shrinks after puberty, but its effect on your body’s defenses last your whole life. Learn more about this important gland.

What Is Graves' Disease?
Graves’ disease is the most common cause of hyperthyroidism, a disorder that causes the thyroid to produce too much thyroid hormone and can cause bulging eyes.
What is Thyroid Hormone Replacement Therapy?
There is really only one option for treating hypothyroidism, and that is thyroid hormone replacement therapy. T4 supplements are the standard form of treatment, but there are other forms available. Article describes importance of therapy.
Addison’s Disease and Adrenal Insufficiency Overview
Addison’s disease, a rare disorder, develops when the adrenal glands do not produce enough of the hormone cortisol. Sometimes, the adrenal glands also don’t produce enough of the aldosterone hormone. Includes list of Addison’s disease symptoms.
Graves’ Disease Treatment
Treatment of Graves’ disease may involve anti-thyroid medications, radioactive iodine, and sometimes a partial or total thyroidectomy. The goal of treatment is to bring your overactive thyroid or hyperthyroidism under control.
Complications of Hypothyroidism
If you have hypothyroidism and don’t seek proper treatment, you risk experiencing a variety of complications. This article describes some of the common problems associated with untreated hypothyroidism.
Symptoms of Hypothyroidism
Symptoms of hypothyroidism include fatigue, sensitivity to cold, dry skin, and hair loss. You don’t have to experience every common symptom to have hypothyroidism, though. Every patient’s set of symptoms is unique.
Graves’ Disease Diagnosis
In diagnosing Graves’ disease, the doctor will measure the level of different hormones, such as TSH, T3, and T4. Learn what tests you may need to have and what each of the results can tell you about your thyroid condition.
Synthetic T4 Supplements for Hypothyroidism
Synthetic forms of T4 hormone are generally called levothyroxine, and they are considered the standard treatment for hypothyroidism. Finding the right dosage is vital to the success of your therapy. Article explains synthetic T4 supplements.
Risk Factors of Hypothyroidism
Age and sex are the two biggest hypothyroid risk factors. However, medical history also plays a part. This article outlines the top risk factors for hypothyroidism, and will help your doctor determine if regular hypothyroid testing is right for you.
Addison’s Disease Treatment
Treatment of Addison’s disease involves replacing the hormones the body is unable to secrete or produce in sufficient quantity. Read about medications you may need to take and what to do in an Addisonian crisis.
Addison’s Disease Causes
There are several causes of Addison’s disease that primarily affect the adrenal glands’ ability to produce the hormone cortisol. Learn the different endocrine conditions that can cause Addison’s disease.
Addison’s Disease Diagnosis
To diagnose Addison’s disease, your doctor will run exams and tests that may include blood tests and CT scans of the brain and abdomen.
Causes of Hypothyroidism
The most common cause of hypothyroidism is Hashimoto’s thyroiditis. But this isn’t the sole cause of hypothyroidism. This article gives an explanation of each of the possible causes of hypothyroidism.
Hypothyroidism Diagnosis
There are a variety of tests that diagnose hypothyroidism. TSH screenings are the first line of testing, but they are not the sole factor in diagnosing the disorder. T4 testing may also be necessary to determining if you are hypothyroid.
