Hypoparathyroidism: Causes, Symptoms and Treatment

The parathyroid glands may be tiny, but they play an important role in maintaining calcium levels. When these glands do not produce enough parathyroid hormone, your body can struggle to maintain healthy calcium and phosphorus levels. This may lead to problems affecting the nerves, muscles, bones, and even your heart.

So, what is hypoparathyroidism? Studies show that it is caused by low levels of parathyroid hormones, leading to hypocalcemia. Basically, it is a rare hormonal disorder that usually develops after autoimmune conditions, neck surgery or certain genetic issues. 

Even though it may sound serious, early diagnosis and the right treatment plan can help manage symptoms effectively and support a much healthier, more stable life. 

Understanding the Condition and Why It Happens

The parathyroid glands are four small glands which are located behind the thyroid in the neck. However, they have very different jobs. Their main role is to produce parathyroid hormone, which helps regulate calcium and phosphorus levels in the blood. 

This hormone helps keep calcium in your body within a healthy range so that your muscles, bones, nerves, and heart can function properly. When these hormone levels become too low, blood calcium drops and blood phosphorus rises, which may lead to cramps, tingling, muscle spasms, and other complications. 

Even though the parathyroid glands are located near the thyroid, hypoparathyroidism is not the same as thyroid disease.

Hypoparathyroidism Causes

There are different causes of hypoparathyroidism, and some of them are seen more often than others. Most often, the condition develops when the parathyroid glands are removed, damaged, or stop working properly, which can affect the body’s ability to maintain normal calcium levels. 

• Autoimmune Conditions: Sometimes, the immune system mistakenly attacks the parathyroid glands, reducing hormone production. 
• Thyroid or Neck Surgery: This one is the most common cause of the ailment. The parathyroid glands can be accidentally damaged or removed during neck surgery.
• Low Levels of Magnesium: If you have very low magnesium levels, it can interfere with the secretion of parathyroid hormone.
• Genetic Disorders: Some people are born with conditions that can affect the development of the function of these glands. 
• Other Rare Conditions: Radiation exposures or infiltrative disease can also affect gland function. 

Hypoparathyroidism Symptoms

The symptoms usually develop because low parathyroid hormone can cause blood calcium levels to drop. 

• Early Signs: Some people notice a tingling feeling around the lips or in the toes and fingers. Muscle cramps and small twitching movements may also appear early and can come and go. 
• Moderate to Severe Signs: When calcium levels drop, some symptoms may become more intense. Some may develop painful muscle spasms, which is also called tetany. They may also feel weakness and tiredness. In severe cases, an abnormal heart rhythm/rate or seizures can also occur that may need urgent medical attention. 
• Long-Term Effects: If the condition is not managed properly, it can lead to brittle nails, dry skin, dental issues and also cataracts. 

Difference Between Hyperparathyroidism and Hypoparathyroidism

Understanding the difference between the two makes it easier to compare how these conditions affect your body’s calcium balance. Here is a simple table to follow: 

Diagnosis and Clinical Classification

Medical practitioners diagnose the condition using various blood tests that measure calcium, phosphorus, magnesium, and parathyroid hormone (PTH) levels. 

If someone has this condition, calcium will typically be low, and phosphorus will typically be high. So, these blood tests will help to confirm the diagnosis. 

A 24 hour urine calcium test to measure calcium levels is sometimes advised to determine whether too much calcium is being lost through the kidneys. Also, an ECG may be done if symptoms suggest an effect on the heart’s rhythm. 

For medical records and insurance coding, hypoparathyroidism ICD 10 commonly includes E20.9 for unspecified hypoparathyroidism. 

Hypoparathyroidism Treatment

The goal of the treatment is to bring calcium back into a safe range in your body and keep symptoms under control. If the symptoms are severe, such as muscle spasms, seizures, or changes in heart rhythm, doctors may give IV (Intravenous) calcium in a hospital setting for faster recovery.

Long-term care usually includes oral calcium supplements and active vitamin D supplements. This helps the body absorb calcium more effectively. Magnesium can also be added if levels are low, as it supports normal parathyroid hormone function. 

Regular blood tests are also vital for monitoring calcium, phosphorus, and kidney-related complications over time. In some cases, if the condition is difficult to control with standard therapy, PTH replacement can be considered under specialist supervision. 

Hypoparathyroidism Diet

A practical diet for this condition usually focuses on calcium-rich foods such as dairy, green leafy vegetables, tofu, broccoli, and fortified foods. 

In certain cases, limiting very high-phosphorus foods like cola drinks, processed foods and certain meats can help. 

It is best not to self-medicate with vitamin D or calcium supplements, as excessive intake can also cause issues. Finally, being hydrated and keeping up with follow-up tests helps treatment work more safely. 

Conclusion

Hypoparathyroidism can affect your daily life if it’s left untreated. However, many people do well with timely diagnosis, the right supplements, a sensible diet and regular monitoring. 

If you notice any of the above symptoms, consult a doctor immediately for proper evaluation.
