Bringing direct personalized endocrine and diabetes care to central Indiana.

Our current insurance-based model of medical care limits the time doctors are able to spend with patients. Patients feel rushed, unheard, and frustrated when they can’t get in touch with their doctor. To provide the best care, doctors need the time to listen and need availability to see patients on a short-notice basis.  In our current healthcare environment, it is becoming increasingly challenging to do that in the traditional third-party (insurance) model. This has led to a growing movement of direct care: a practice style where there is a direct line of communication between doctor and patient, minimal wait for appointments, longer visits, price transparency. Increasingly common, direct care clinics increase the likelihood of early disease detection and prevention. In turn, the patient pays the doctor directly, similar to other services we familiar in daily life.

At Impact Endocrinology, Dr. Grethen sees patients with a variety of endocrine conditions including type 1 diabetes, type 2 diabetes including complex disease, patients on insulin pumps, CGMs, pre--diabetes, obesity, metabolic syndrome, thyroid disease, adrenal disease, pituitary disease, osteoporosis, calcium-related disorders and many others. She sees patients for one-time consultations and also manages chronic complex disease over the long-term. We invite you to experience the excellent endocrine care you deserve.

What is endocrinology? Which patients would benefit from a consultation at Impact Endocrinology?

Endocrinology is a subspecialty of Internal Medicine that focuses on patients who have a disease or medical condition in which there is excess or insufficient hormone production. Hormones produced in our bodies work together to maintain a balance of the intricate systems and mechanisms to keep us healthy. When these hormones are not balanced properly, we see adverse health effects and disease. For example, when insulin levels are abnormal, we may see metabolic syndrome or diabetes. Excess of insufficient thyroid hormone can cause very different complexes of symptoms and physiologic effects. Vitamin D and parathyroid hormone affect bone health. Imbalances in the pituitary gland affects multiple parts of the body. The endocrine system plays an essential role in all other systems in the body – cardiovascular, gastrointestinal, immune, among others. Dr. Grethen at Impact Endocrinology provides care for patients with a variety of endocrine diseases and concerns.
