Manage your diabetes, maximize your health

Diabetes and Endocrinology Care at Anna Jaques Hospital

If you’re diagnosed with diabetes, a metabolic disorder or another endocrine condition, you need to carefully manage your health. Our specialists help you regulate your nutrition, improve physical activity and balance hormone levels.

What is an Endocrinologist?

Our endocrinologists at Anna Jaques Hospital specialize in diagnosing and treating conditions caused by changes in your hormone levels. This means ensuring your endocrine system is working properly.

Glands and organs make up your endocrine system. They secrete hormones that act as chemical messengers. The hormones travel through your blood and tell organs and other parts of your body how to function.

Hormones and endocrine glands control a variety of functions in your body:

  • Appetite
  • Body temperature
  • Blood pressure
  • Growth and development
  • Heart rate
  • Metabolism
  • Sexual function and reproduction
  • Sleeping and waking cycles

Conditions We Treat

We treat the full range of diabetic and endocrine conditions.


Diabetes occurs when your body cannot produce insulin to break down the sugar in your blood. This means your body cannot convert food into the energy you need for daily activities.

Symptoms of diabetes include hunger, thirst, excessive urination, dehydration and weight loss. Diabetes tends to run in families. Other factors that may cause diabetes include extra body weight and poor nutrition.

Diabetes is one of the nation’s biggest health concerns. More than 37 million people are living with diabetes. The number continues to grow.

There are different types of diabetes. Two chronic forms of diabetes are:

  • Type I diabetes. Cells in your pancreas are damaged and don’t make insulin. Your body cannot control the level of sugar in your blood. Ten percent of people with diabetes have this form of the condition.
  • Type II diabetes. Your body cannot make enough insulin or react to insulin effectively. This lets glucose buildup in your bloodstream. Ninety percent of people with diabetes have Type II.

Other forms of diabetes include:

  • Prediabetes. If your blood sugar levels are higher than normal, you’re at risk for Type II diabetes. You may be able to prevent diabetes by eating a healthy diet, losing weight and exercising.
  • Gestational diabetes. This condition occurs in pregnant people who cannot make enough insulin. Once the baby is born, the condition usually goes away.

We also treat conditions related to diabetes, such as foot ulcers caused by neuropathy. Neuropathy is the loss of the ability to feel pain caused by nerve damage from diabetes.

Endocrine Conditions

We diagnose and manage a wide range of endocrine disorders, such as:

  • Addison’s disease occurs when the adrenal glands don’t produce enough aldosterone or cortisol
  • Cushing syndrome, caused by high levels of the hormone cortisol
  • Goiter, an irregular cell growth or enlargement of the thyroid that forms one or more lumps in the thyroid gland
  • Hyperthyroidism occurs when your thyroid gland makes too much thyroid hormone
  • Hypogonadism, caused by too little production of the sex hormone testosterone
  • Hypothyroidism occurs when your thyroid makes too little thyroid hormone
  • Osteoporosis, an abnormal loss of bone mass and changes in bone tissue caused by low estrogen levels
  • Polycystic ovary syndrome (PCOS) occurs when the reproductive hormones in people with ovaries are unbalanced
  • Thyroid nodules, fluid-filled lumps form in your thyroid
