Why choose Natural Endocrinology Specialists™

Scottsdale's best naturopathic hormone specialists

Natural Endocrinology Specialists™ (NES) was founded by Dr. Linda Khoshaba, NMD, FABNE. Her office is located in Scottsdale, Arizona, yet patients all around the valley use her as their primary doctor. What separates NES™ from the rest is simple: we actually listen.

Patients choose NES™ because they want to address the root cause of their issues, rather than just masking symptoms with multiple medications. Many feel frustrated after being told "your labs are normal" or "this is just part of aging," yet still don't feel like themselves.

We understand, and we're here to help you reach your optimal health. At NES™, we prioritize natural and clean medications and supplements to support your wellness journey.

I can’t say enough wonderful things about Dr. Khoshaba and her entire team at Natural Endocrinology Specialists in Scottsdale. From the moment you walk through the door, they make you feel like family. Dr. K is incredibly thorough and takes the time to explain every aspect of your care — from the process, to the testing, to the results. She genuinely cares, listens, and makes sure you fully understand your health and the path forward.

It’s rare to find a provider who combines deep expertise with such compassion, and Dr. K is truly one of a kind. Her staff is just as warm, supportive, and attentive. I feel so grateful to have found them and would recommend NES to anyone looking for exceptional, personalized care.

Dr. Khoshaba is very good and supportive.
The only downside is her very high visit costs at $275/30 minute, which meas we can only afford to use her skill set on a randum/infrequent basis.

What's the Connection Between Thyroid and Insulin Resistance

The endocrine system operates through a network of feedback loops. Thyroid hormones set the baseline metabolic rate while insulin directs glucose storage. Low thyroid production reduces glucose uptake in peripheral tissues. This forces the pancreas to secrete extra insulin which gradually blunts cellular receptor response. Hyperinsulinemia then suppresses the conversion of thyroxine to active triiodothyronine. […]

How Is Hashimoto’s Linked to Low Cortisol Levels?

Hashimoto’s thyroiditis may be linked to low cortisol levels through autoimmune activity, chronic inflammation, and disruptions in the hypothalamic-pituitary-adrenal (HPA) axis, which controls the body’s stress response. People with Hashimoto’s also have a higher risk of developing adrenal disorders such as Addison’s disease, while hypothyroidism itself can affect cortisol metabolism and stress regulation.

That may sound like a big medical term, but the idea is simple: PCOS was never just about ovarian cysts. It is a hormone and metabolism […]
