Medex DTC Top Endocrinologists in Queens manage conditions like diabetes, thyroid disorders, metabolic imbalances, and hormone-related issues such as infertility or osteoporosis. Endocrinologists use both medical treatments and lifestyle recommendations to help regulate hormone levels and improve overall health. The endocrine system not only supports other systems, but it may also be the source of many disorders.
Endocrinologists diagnose and treat problems with the glands that make hormones: the thyroid, pancreas, adrenals, pituitary, parathyroids, ovaries and testes. These are the conditions we see most often.
We manage type 1, type 2 and gestational diabetes, and help patients with prediabetes stop it from progressing. Care includes A1C tracking, medication and insulin adjustment, continuous glucose monitor (CGM) review, and screening for eye, kidney, nerve and heart complications with our in-house specialists.

An underactive thyroid (hypothyroidism) can cause fatigue, weight gain and feeling cold. An overactive thyroid (hyperthyroidism) can cause a racing heart, weight loss and anxiety. We treat both, including Hashimoto’s thyroiditis and Graves’ disease, and evaluate goiters and thyroid nodules with ultrasound.
Polycystic ovary syndrome can cause irregular periods, acne, excess hair growth and weight gain, and raises the risk of diabetes. We work with our gynecology team on hormone testing and treatment. Read about PCOS care at Medex DTC.
Low bone density often has no symptoms until a fracture. We order DEXA bone density scans, check calcium and vitamin D levels, and treat osteoporosis and parathyroid problems that weaken bones. Learn about bone density testing.
When weight won’t come off despite diet and exercise, a hormone problem such as insulin resistance, hypothyroidism or PCOS may be part of the cause. We test for these and build a medical weight plan, which can include prescription medication when appropriate. See our obesity treatment page.
Low testosterone (hypogonadism) can cause low energy, reduced sex drive, loss of muscle and mood changes. We confirm the diagnosis with proper morning blood tests before discussing treatment options.
We evaluate less common but serious conditions, including Cushing’s syndrome, Addison’s disease, adrenal nodules and pituitary hormone problems, and coordinate imaging and hospital referrals when needed.
We also treat hyperparathyroidism, high calcium, metabolic syndrome, hirsutism and hormone-related hair loss.

We accept most insurance for endocrinology visits, including:
Some HMO and managed Medicaid plans require a referral from your primary care doctor before you see a specialist. If you need one, our own primary care doctors can see you and refer you in-house. Call (718) 275-8900 to check your coverage before your visit, or see our full insurance list.
Your first appointment usually takes 45–60 minutes. Follow-up visits are shorter.
What to bring:
Some blood tests need fasting or a morning draw. We’ll tell you when you book.
Hormone conditions rarely affect just one part of the body. Diabetes affects the eyes, kidneys, nerves, feet and heart. That’s why having every specialist under one roof matters.

What does an endocrinologist treat? An endocrinologist treats disorders of the hormone-producing glands. The most common are diabetes, thyroid disease, PCOS, osteoporosis, low testosterone, and adrenal and pituitary problems.
When should I see an endocrinologist instead of my primary care doctor? See an endocrinologist if your diabetes or thyroid levels stay out of range despite treatment, if you have a thyroid nodule, or if your doctor suspects a less common hormone disorder. Your primary care doctor can refer you, and at Medex that referral stays in the same building.
Do I need a referral to see an endocrinologist in Queens? It depends on your plan. Most HMO and many managed Medicaid plans require a referral; PPO plans and original Medicare usually don’t. Call (718) 275-8900 and we’ll check for you.
Does Medex accept Medicare and Medicaid for endocrinology? Yes. We accept Medicare, Medicaid, HIP, EmblemHealth, GHI, MetroPlus, Fidelis Care and most commercial plans.
What happens at the first endocrinology visit? The doctor reviews your history and symptoms, examines you and orders blood tests or imaging if needed. You leave with a treatment plan or clear next steps. Plan on 45–60 minutes.
Can an endocrinologist help with weight loss? Yes. An endocrinologist checks for hormone causes of weight gain, such as insulin resistance, hypothyroidism and PCOS, and can prescribe weight-loss medication when it’s medically appropriate.
Should I see an endocrinologist or an ENT for a thyroid problem? Start with an endocrinologist for thyroid function problems and most nodules. An ENT or surgeon is needed if a nodule, goiter or cancer requires surgery, and we’ll refer you if so.
Where is your endocrinology office? At 111-29 Queens Blvd in Forest Hills, near the Forest Hills–71 Av station on the E, F, M and R lines. We’re open Monday–Friday, 9 am–8 pm.
Whether you’ve just been diagnosed with diabetes, your thyroid levels won’t settle, or you’re not sure what’s behind your symptoms, we can help you find answers. Book online or call our Forest Hills office today.
