Internal Medicine

As we get older, we outgrow things…even the doctor who cared for us since childhood.

Once you’re graduated from high school, you can appreciate the help and insight from doctors who specialize in caring for grown-ups.

Find an Internal Medicine doctor who fits your needs as an adult.


Your endocrine system includes glands and organs that make hormones. Your body needs hormones to grow and develop, and for metabolism and sexual function. When hormone levels are too high or too low, they can affect everything from your mood to your bone strength.

Endocrinologists are doctors who specialize in these types of disorders. At PeaceHealth, endocrinologists work with a wide range of specialists to care for children and adults, including:

  • Dietitians and fitness experts
  • Nephrologists (kidney specialists)
  • Primary care doctors
  • Weight loss experts

Many endocrine conditions need lifelong management. Your care team will make sure you know how to take good care of yourself — whether that means following a special diet or looking out for symptoms.
