Parathyroid symptoms: general informational overview

Four tiny parathyroid glands sit in the neck, typically just behind the thyroid gland. Despite their small size, these glands play a vital part in maintaining healthy levels of calcium and phosphorus by releasing parathyroid hormone (PTH). Balanced calcium and phosphorus are essential for many body functions, including strong bones and proper nerve and muscle activity. When these glands do not function properly, a range of symptoms may appear, such as muscle weakness, fatigue, or bone pain. Such signs often point to deeper issues with parathyroid activity, making it important to understand how these glands contribute to overall health.

Common Symptoms of Parathyroid Disorders

Alterations in parathyroid function can manifest through symptoms related to calcium imbalance. When the glands produce too much PTH, a condition known as hyperparathyroidism, it often results in elevated calcium levels in the blood, a state called hypercalcemia. Conversely, insufficient PTH production can cause hypoparathyroidism, leading to low calcium levels, or hypocalcemia. Both conditions can produce a range of symptoms, though some individuals may remain asymptomatic.

Symptoms Associated with Hyperparathyroidism

In cases of hyperparathyroidism, excess PTH causes calcium to be released from bones into the bloodstream. This process can weaken bones, increasing the risk of fractures. Elevated calcium levels may also lead to symptoms such as fatigue, muscle weakness, or joint pain. Some individuals experience digestive disturbances, including nausea, constipation, or abdominal pain. Neurocognitive effects like confusion, difficulty concentrating, or irritability may occur as well. In severe cases, high calcium levels can cause dehydration or kidney stones, prompting further medical investigation.

Symptoms of Hypoparathyroidism

When PTH levels are low, calcium levels in the blood decrease, leading to hypocalcemia. Symptoms associated with low calcium may include numbness or tingling sensations, especially around the lips, fingers, or toes. Muscle cramps or spasms, known as tetany, can also develop. Some individuals might experience fatigue, weakness, or mood changes. In rare instances, severe hypocalcemia can result in seizures or cardiac irregularities, emphasizing the importance of recognizing early signs.

Additional Considerations

It is important to note that parathyroid symptoms can overlap with other medical conditions, making diagnosis challenging without appropriate testing. Blood tests measuring calcium and PTH levels are typically used to assess parathyroid function. Imaging studies may help identify enlarged glands or other abnormalities. Understanding the symptoms associated with parathyroid disorders can aid in early detection and help guide further evaluation by healthcare professionals.
