FCPP Endocrinology Group

Endocrinology is the study of medicine related to the endocrine system, which controls hormones. Our body’s glands produce and release hormones into the bloodstream. Hormones then travel to various tissues in the body to prompt them to do a specific action. When the glands do not produce the right number of hormones, diseases may develop and can affect many aspects of a person’s life.

The endocrinologists at First California Physician Partners are trained to diagnose and treat hormonal imbalances. We work hand in hand with our patients’ primary care physicians and other specialists to provide comprehensive endocrinology services.

Where Do Hormones Come From?

Although hormones can reach all parts of the body, only target cells with compatible receptors can follow a hormone’s instructions. The endocrine system is composed of specialized glands that release hormones directly into the bloodstream:

Other body tissues outside the endocrine system can also release hormones, such as:

What Is an Endocrinologist?

An endocrinologist is a doctor with specialized training in diagnosing and treating conditions affecting the endocrine system, such as:


Why Would You See an Endocrinologist?

Endocrine conditions can produce a range of symptoms depending on which glands or body tissues are affected. Some people have no symptoms, while others experience debilitating symptoms that affect daily life. Here are some symptoms associated with endocrine disorders:

  • Appetite loss
  • Digestive problems
  • Excessive hunger or thirst
  • Frequent urination
  • Irritability, depression and other mood changes
  • Joint and muscle pain
  • Nausea
  • Unexplained weight loss or gain
  • Upper body weight gain
  • Weakness and fatigue

If you experience any of the symptoms above, speak with your primary care physician. They may refer you to an endocrinologist for specialized care after carefully evaluating your medical history, symptoms and possible risk factors for endocrine diseases. Many endocrine disorder symptoms overlap with those of other conditions. As such, a range of diagnostic tools and tests may be done to diagnose an endocrine disorder:

  • Blood tests
  • Genetic tests
  • Imaging scans
  • Urine tests

What Is a Registered Dietitian?

A registered dietitian has special training in nutrition and diet. They offer advice on healthy eating habits and nutrition to help patients improve their health and well-being. Registered dietitians strive to help patients meet their nutritional needs, especially those with medical conditions such as eating disorders, food allergies, heart disease and more.

Specific dietary patterns may worsen endocrine disorders or undermine treatments for these conditions. A registered dietitian can recommend a diet for patients that can help reduce the symptoms, severity and risks associated with endocrine disorders.
