What is hyperparathyroidism?
Hyperparathyroidism occurs when one
or more of your parathyroid glands are overactive. You have four of these tiny glands.
Each one is about the size of a pea. They are found in your neck, next to the thyroid
gland. They keep the amount of calcium in your blood in a normal range. They also keep
the levels of magnesium and phosphorus normal. If these glands are overactive, they make
too much parathyroid hormone (PTH). That raises the level of calcium in your blood.
PTH causes calcium to be released
from your bones. This loss of calcium from the bones can lead to weak, brittle bones
(osteopenia and osteoporosis) and bone fractures. When the blood with this high calcium
goes through the kidneys, the calcium may be filtered into the urine. That can lead to
What causes hyperparathyroidism?
Hyperparathyroidism most often
happens when one of your parathyroid glands gets larger or has a tumor on it. The gland
then makes too much parathyroid hormone. Most people with this problem have one abnormal
gland. Some people may have two abnormal glands. A small number of people have four
abnormal glands. Having four abnormal glands is rare. It is often a genetic problem. In
most cases, if a tumor is causing the gland to be overactive, the tumor is not cancer
(benign). In rare cases, the tumor may be cancer.
Who is at risk for hyperparathyroidism?
You may be more likely to have hyperparathyroidism if:
- You are a woman who has already gone through menopause
- You have a family history of related conditions
- You have had radiation therapy on your head and neck
- You have taken medicines such as
lithium, a medicine used to treat bipolar disorder
What are the symptoms of hyperparathyroidism?
Each person may have symptoms in a
different way. But these are the most common symptoms:
- Joint aches and pains
- Belly (abdominal) pain
- Gastroesophageal reflux disease
- Peptic ulcer disease
- Tiredness (fatigue)
- Urinating more than normal
- Increased thirst
- Loss of appetite
- Muscle weakness
- Kidney stones
These symptoms may look like other health problems. Always see your healthcare provider for a diagnosis.
How is hyperparathyroidism diagnosed?
A blood test can often find hyperparathyroidism. It can spot high levels of calcium and parathyroid hormone. You may also need a urine test. This can measure the calcium in your urine over 24 hours.
How is hyperparathyroidism treated?
Treatment will depend on your symptoms, age, and general health. It will also depend on
how severe the condition is.
- Surgery. If your case is more
severe, your parathyroid gland may need to be removed. Before surgery, you may
have an imaging test to find out which gland is abnormal. You may have an
ultrasound of the neck. Knowing which gland is abnormal will shorten the
surgery. It will also allow the surgeon to make a smaller cut (incision) right
over the abnormal gland.
- Monitoring If you condition is mild, your
healthcare provider may closely monitor your condition to condition to make
sure it doesn’t get worse.
- Medicines. Ask your healthcare
provider about medicines such as cinacalcet.
Living with hyperparathyroidism
You will likely need to have your
calcium and vitamin D levels and bone density checked from time to time. Your healthcare
provider will then be able to make sure your problem is under control.
When should I call my healthcare provider?
Tell your healthcare provider if your symptoms get worse or you have new symptoms.
Key points about hyperparathyroidism
- Hyperparathyroidism happens when one
or more of your parathyroid glands are overactive. The glands make too much
parathyroid hormone. That raises the level of calcium in your blood. It then lowers
the calcium in your bones.
- It most often happens when a parathyroid gland gets larger or has a tumor on it.
- The loss of calcium from the bones can
lead to weak, brittle bones (osteopenia and osteoporosis) and bone fractures.
- A routine blood test can spot high levels of calcium.
- The most common treatment is surgery. The abnormal gland is removed.
Tips to help you get the most from a visit to your healthcare provider:
- Know the reason for your visit and what you want to happen.
- Before your visit, write down questions you want answered.
- Bring someone with you to help you ask questions and remember what your provider tells you.
- At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you.
- Know why a new medicine or treatment is prescribed, and how it will help you. Also know what the side effects are.
- Ask if your condition can be treated in other ways.
- Know why a test or procedure is recommended and what the results could mean.
- Know what to expect if you do not take the medicine or have the test or procedure.
- If you have a follow-up appointment, write down the date, time, and purpose for that visit.
- Know how you can contact your provider if you have questions.
