Services at Our Manhattan Endocrinology Office

Diabetes

Management for Types 1 & 2

The root cause of both diabetes type 1 and type 2 is a lack of insulin, the hormone that converts glucose, or sugar, into usable energy for your body. When uncontrolled, diabetes can cause heart attacks or stroke.

Typically, diabetes is a life-long condition, so our treatment plans are comprehensive, teaching a diabetic anti-inflammatory diet, lifestyle modifications, and insulin pump management.

We are your one-stop-shop for diabetes management! We provide fingersticks and insulin injections, nutritional and lifestyle counseling, and emergency diabetes care.

Thyroid Disorders

Hypothyroidism, Hyperthyroidism & Thyroid Cancer

Thyroid disorders are extremely common, affecting over 12% of the US population, and one in eight women. While there are multiple causes for thyroid conditions, most can be successfully managed throughout a person’s lifetime.

Receiving diagnosis and treatment for your thyroid condition is important, as an undiagnosed condition can lead to a host of other health issues.

We take a unique approach to thyroid dysfunction, acting as your one-stop-shop for testing, diagnosis, and treatment, eliminating the need to see multiple specialists.

Osteoporosis

Osteoporosis, Vitamin D Deficiency & Nutrition

Vitamin D deficiencies affect a large portion of the population: an estimated one billion people worldwide. They pose serious health risks, including osteoporosis, which is often unnoticed until a patient breaks a bone or is otherwise injured.

While our bodies naturally create Vitamin D from sun exposure, most of us do not get enough sun to maintain healthy levels on our own.

At Dr. Mezitis’ office, we take a customized health management approach to treating both Vitamin D deficiencies and osteoporosis, with a focus on whole-body nutrition and lifestyle wellness.

Hormone Disorders

Polycystic Ovarian Syndrome (PCOS), Female and Male Infertility, Low Testosterone, Adrenal Gland Disorders, Parathyroid Disease, Pituitary Disorders and More

Polycystic Ovarian Syndrome (PCOS) is a common hormonal condition in reproductive-aged women. If left untreated, it can cause female infertility, hirsutism, and other serious health problems. 

Our office treats female infertility along with male infertility setting the stage for conception. We also treat low male testosterone and other less common hormone disorders such as Cushing‘s Disease and Acromegaly.

The endocrine system produces hormones that affect the entire body, causing a variety of health problems if not properly treated. Our whole-body approach ensures optimal health and wellness.

Nutrition

We believe a balanced lifestyle plays a key role in health and wellness. We work with all of our patients to develop healthier lifestyle choices, including personalized nutrition advice centered around the Mediterranean diet, a proven healthy eating pattern recognized by the World Health Organization.
