Hyperparathyroidism is a condition that occurs when the parathyroid glands in your neck produce too much parathyroid hormone (PTH). This hormone is essential for regulating calcium levels in the blood, but when the balance is disrupted, it can cause a variety of health issues. One of the lesser-known but increasingly studied symptoms of hyperparathyroidism is insomnia, or the difficulty in falling and staying asleep.
What Is Hyperparathyroidism?
Hyperparathyroidism occurs when one or more of the parathyroid glands become overactive. These glands are responsible for controlling the body’s calcium and phosphorus levels. When they produce too much PTH, it leads to elevated calcium levels in the blood, which can cause complications throughout the body.
There are two types of hyperparathyroidism:
Primary hyperparathyroidism: Usually caused by a benign tumor on one of the parathyroid glands.
Secondary hyperparathyroidism: Often develops due to other conditions like kidney disease or vitamin D deficiency.
Can Hyperparathyroidism Affect Sleep?
Yes, hyperparathyroidism can indeed affect sleep. Although the relationship between hyperparathyroidism and insomnia is not fully understood, research suggests that elevated calcium levels caused by excessive PTH production can interfere with normal sleep patterns.
Here’s how hyperparathyroidism can contribute to insomnia:
1. Elevated Calcium Levels and Brain Function
Calcium plays a crucial role in brain function, particularly in how neurons communicate. When calcium levels are too high (a condition known as hypercalcemia), it can disrupt normal brain activity, leading to problems such as anxiety, irritability, and difficulty sleeping. These symptoms are common in people with hyperparathyroidism.
2. Fatigue and Restlessness
People with hyperparathyroidism often report feeling unusually tired during the day. This fatigue can paradoxically make it harder to sleep at night, as the body becomes unable to maintain a regular sleep-wake cycle. The body’s internal clock, known as the circadian rhythm, may become disturbed, leading to restless nights and frequent awakenings.
3. Bone Pain and Discomfort
Excessive PTH causes calcium to be drawn from the bones, leading to osteoporosis or bone pain. This pain can become worse at night, making it hard for people to find a comfortable position to sleep in. Chronic pain is a well-known contributor to insomnia.
4. Mood Disorders and Anxiety
Hyperparathyroidism is associated with mood swings, depression, and anxiety, all of which can contribute to sleep problems. Anxiety, in particular, can make it difficult to fall asleep and stay asleep, as racing thoughts and an overactive mind prevent relaxation.
Symptoms of Insomnia in Hyperparathyroidism
If you have hyperparathyroidism, you may experience the following insomnia-related symptoms:
Difficulty falling asleep.
Waking up frequently during the night.
Waking up too early and being unable to fall back asleep.
Feeling tired or groggy during the day despite getting enough sleep.
A sense of restlessness or an inability to get comfortable.
How Is Insomnia Diagnosed in Hyperparathyroidism?
If you are experiencing insomnia and have hyperparathyroidism, it’s important to talk to your doctor. They will assess your symptoms and may perform tests to measure your calcium and PTH levels.
Your doctor may also ask about your sleep habits, overall health, and any underlying conditions that could be contributing to insomnia. In some cases, a sleep study may be recommended to better understand your sleep patterns.

Treating Insomnia in Hyperparathyroidism
Addressing insomnia in hyperparathyroidism requires treating the underlying condition. Here are some potential treatment options:
1. Surgery for Primary Hyperparathyroidism
For people with primary hyperparathyroidism, the most effective treatment is often parathyroidectomy, a surgical procedure to remove the overactive gland(s). After surgery, calcium levels in the blood usually return to normal, which can improve sleep and reduce symptoms of insomnia.
2. Medications
In cases where surgery is not an option, medications may be used to manage the symptoms of hyperparathyroidism. Bisphosphonates or calcimimetics can help control calcium levels, which may improve sleep quality.
3. Calcium and Vitamin D Supplements
For secondary hyperparathyroidism, especially when caused by kidney disease or a vitamin D deficiency, taking calcium and vitamin D supplements can help regulate PTH levels and improve overall health. This may also alleviate some of the sleep problems associated with the condition.
4. Sleep Hygiene
Regardless of the cause of your insomnia, practicing good sleep hygiene can be beneficial. Here are some tips to help improve your sleep quality:
Stick to a sleep schedule: Go to bed and wake up at the same time every day, even on weekends.
Create a calming bedtime routine: Engage in relaxing activities like reading, taking a warm bath, or listening to soft music before bed.
Avoid caffeine and heavy meals before bed: These can interfere with sleep.
Create a comfortable sleep environment: Make sure your bedroom is dark, quiet, and at a comfortable temperature.
Limit screen time before bed: The blue light from phones, tablets, and computers can disrupt your body’s natural sleep cycle.
5. Managing Anxiety and Stress
Since anxiety is a common issue for people with hyperparathyroidism, learning how to manage stress is important for improving sleep. Techniques like deep breathing exercises, meditation, and progressive muscle relaxation can help calm the mind and body, making it easier to fall asleep.
Can Treating Hyperparathyroidism Improve Sleep?
Yes, treating the underlying hyperparathyroidism can lead to significant improvements in sleep. Many people report that their insomnia improves after undergoing surgery or other treatments to normalize their calcium levels. As calcium levels stabilize, the body’s natural processes can function more smoothly, including those that regulate sleep.
It’s important to note that recovery from hyperparathyroidism isn’t always immediate. Some people may continue to experience sleep disturbances for a while after treatment, especially if anxiety or mood disorders are present. However, most patients experience gradual improvement over time.
Conclusion
Hyperparathyroidism can cause insomnia by disrupting calcium levels in the body, leading to problems like anxiety, mood disorders, and bone pain. If you’re experiencing sleep problems related to hyperparathyroidism, it’s crucial to seek medical advice. Treatment options like surgery, medications, and lifestyle changes can help improve sleep and restore your quality of life. By addressing the underlying cause, you can overcome insomnia and enjoy better health.
